Essential Chef Techniques to Improve Your Cooking

In a professional kitchen, you shouldn’t rely on strict step-by-step instructions for every plate. Rely on foundational methods. Once you understand how heat, moisture, and time interact with food, you are no longer bound to a recipe. You can open a fridge, look at what you have, and know exactly what to do.

This guide breaks down the seven essential techniques every cook should master: knife skills, searing, roasting, poaching, steaming, braising, and stir-frying. Each technique is demonstrated through a complete meal and a versatile sauce.

Whether you cook meat, fish, or strictly vegetarian, the underlying physics of the kitchen remain exactly the same. Master the method, and the meal takes care of itself.

01. Knife Skills and Mise en Place

The Meal:
Fattoush with Crisp Halloumi
The Sauce:
Sumac and lemon dressing
Skill level
Easy
Equipment
Chef's knife, chopping board, mixing bowl

Mise en place translates to "everything in its place." It is the discipline of preparation: vegetables prepped, dressings mixed, and tools ready before a single pan hits the heat. Once a pan is hot, you do not have time to stop and chop.

When it comes to knife work, consistency matters far more than speed. Ingredients cut to a uniform size cook at a uniform rate. Rely on three primary cuts: a dice for structure, a julienne for fine matchsticks, and a chiffonade, tightly rolling herbs and slicing them into ribbons so they remain vibrant and unbruised.

The Most Common Mistake

Chopping herbs with a blunt knife or repeating the motion. This crushes the cell walls and turns the edges black. Roll the leaves tightly and slice cleanly through them just once.

Fattoush with Crisp Halloumi

Serves 4 | 25 min prep | 10 min cook

Ingredients

  • 2 pitta or flatbreads
  • 1 tbsp olive oil, for the bread
  • 200g halloumi, sliced 1cm thick
  • 4 ripe tomatoes
  • 1 cucumber
  • 6 radishes
  • 1 small red onion
  • 1 romaine lettuce
  • 30g flat-leaf parsley & 15g mint
  • 3 tbsp extra-virgin olive oil
  • 1 tbsp lemon juice
  • 1 tbsp pomegranate molasses
  • 1 tbsp sumac
  • 1 garlic clove, crushed
  • Salt and black pepper

Method

  1. 1Heat the oven to 200°C (180°C fan). Tear the pitta into rustic pieces, toss with olive oil and salt, and bake for 8-10 minutes until crisp. Allow to cool on the tray.
  2. 2Cut the tomatoes into 2cm wedges. Halve the cucumber lengthways, scrape out the watery seeds to protect your dressing, and cut into 1cm half-moons.
  3. 3Finely slice the radishes and red onion. Shred the lettuce into wide ribbons.
  4. 4Stack the parsley and mint leaves, roll them into a tight cylinder, and slice across into thin ribbons (chiffonade). Do this right before dressing to preserve their bright colour.
  5. 5Whisk the lemon juice, molasses, sumac, garlic, and salt. Stream in the olive oil slowly, whisking continuously until the dressing binds and thickens.
  6. 6Sear the halloumi in a dry non-stick pan over medium-high heat for 2 minutes per side until deeply golden.
  7. 7Toss the vegetables and herbs with the dressing. Fold in the crisp bread and warm halloumi at the very last moment to preserve the textural contrast.

Mastering the Sauce: Sumac and lemon dressing

The classic vinaigrette ratio is three parts oil to one part acid. Here, sumac provides an earthy sourness, while pomegranate molasses adds depth. Whisk your acid, salt, and base flavourings first, then emulsify by streaming the oil in slowly.

Application: Spoon this over roasted aubergine, use it to dress lentils, or toss it through any crisp summer salad.

02. Searing

The Meal:
Seared Sirloin with Red Wine Sauce
The Sauce:
Red wine pan sauce
Skill level
Easy
Equipment
Heavy carbon steel, cast iron or stainless steel pan, tongs

Searing is the pursuit of the Maillard reaction, the chemical process that creates the deep, savoury crust on the surface of food. This reaction requires two things: a completely dry surface and intense, sustained heat.

Any surface moisture will boil and steam the food before it can brown. Pat your ingredients meticulously dry and season them at the last possible moment. Avoid non-stick pans for this technique; they cannot retain the necessary heat. Use heavy carbon steel, cast iron, or stainless steel.

The Most Common Mistake

Moving the food too early. Protein will naturally stick to the metal as the crust forms and release itself when it is ready. If it resists your tongs, leave it alone.

Seared Sirloin with Red Wine Sauce

Serves 4 | 15 min prep | 35 min cook

Ingredients

  • 4 sirloin steaks, ~200g each (2cm thick)
  • 600g new potatoes
  • 2 tbsp olive oil & 1 tbsp neutral oil (for searing)
  • 100g watercress
  • 1 shallot, finely diced
  • 150ml red wine & 150ml beef stock
  • 1 tsp Dijon mustard
  • 1 tbsp cold butter
  • 2 sprigs thyme
  • Salt and black pepper

Method

  1. 1Bring the steaks to room temperature 30 minutes prior. Cold meat seizes upon hitting the pan, resulting in an uneven cook.
  2. 2Boil the potatoes for 15-18 minutes until tender. Drain and steam dry for 5 minutes. Crush each gently with the base of a glass, toss with olive oil and salt, and roast at 220°C (200°C fan) for 20-25 minutes until the edges are brittle and crisp.
  3. 3Pat the steaks aggressively dry. Season heavily with salt.
  4. 4Place a heavy skillet over high heat until just smoking. Add the neutral oil, lay the steaks in, and leave them entirely alone for 2.5 minutes.
  5. 5Turn once. Cook for another 2.5 minutes for a perfect medium-rare. The centre should yield with a gentle spring. Remove and rest on a board for 5-8 minutes.
  6. 6Pour off the excess fat from the pan. Soften the shallot for 1 minute, deglaze with the red wine, and scrape the caramelised fond from the base of the pan. Reduce by half.
  7. 7Add the stock and thyme, reducing by half again. Remove from the heat, whisk in the mustard and cold butter to mount the sauce, and stir in the resting juices.

Mastering the Sauce: Red wine pan sauce

A pan sauce relies on four precise steps: sear your ingredient, deglaze the caramelised fond with acid, reduce to concentrate the flavour, and whisk in cold butter off the heat (monter au beurre) for a glossy, rich finish.

Application: Deglaze with white wine or cider instead, or use this technique after searing thick wedges of cabbage or celeriac steaks.

03. Roasting

The Meal:
Harissa Roast Chicken and Chickpeas
The Sauce:
Harissa yoghurt
Skill level
Easy
Equipment
Large roasting tray or two, tongs

Roasting uses dry, ambient heat to transform ingredients. The exterior caramelises while the interior slowly yields and cooks through.

The secret to a great roast is spatial awareness. Vegetables release significant water vapour as they heat. If your tray is crowded, that vapour is trapped, and your ingredients will steam rather than roast. Give your ingredients room to breathe, even if it means using two trays.

The Most Common Mistake

Overcrowding the pan. A packed tray guarantees soft, pale vegetables regardless of how high your oven is set. You shouldn't force ingredients into a single layer if they touch; split them across two trays.

Harissa Roast Chicken and Chickpeas

Serves 4 | 15 min prep | 40 min cook

Ingredients

  • 8 boneless, skinless chicken thighs
  • 2 tbsp rose harissa
  • 1 tbsp olive oil
  • 1 lemon, zest and juice
  • 2 red onions, cut into wedges
  • 3 carrots, cut into batons
  • 400g tin chickpeas, drained and thoroughly dried
  • 150g couscous
  • 200ml hot stock
  • 200g Greek yoghurt (plus 1 tsp harissa)
  • Small bunch mint, chopped
  • Salt and black pepper

Method

  1. 1Heat the oven to 220°C (200°C fan). Combine the harissa, olive oil, lemon zest, and a generous pinch of salt. Coat the chicken thoroughly.
  2. 2Arrange the onions, carrots, and chickpeas in a single, uncrowded layer on a large roasting tray. Season and roast alone for 10 minutes.
  3. 3Push the vegetables to the perimeter. Place the chicken in the centre and roast for a further 25-30 minutes until the chicken reaches an internal temperature of 75°C.
  4. 4Pour the boiling stock over the couscous, cover to trap the steam, and let stand for 5 minutes. Fluff with a fork and dress with the lemon juice.
  5. 5Rest the chicken for 5 minutes on the tray to let the juices redistribute.
  6. 6Stir the yoghurt with a splash of water to loosen it, gently ripple the extra harissa through, and scatter with fresh mint.

Mastering the Sauce: Harissa yoghurt

A cold, acidic sauce served alongside rich, hot roasted food provides the same comforting moisture as a gravy, but with a sharp contrast that cuts through the fat.

Application: Spoon under a roasted aubergine half, use as a flatbread dip, or thin it out to dress a roasted grain bowl.

04. Poaching

The Meal:
Salmon Poached in Court-Bouillon
The Sauce:
Salsa verde
Skill level
Moderate
Equipment
Wide, shallow pan with a lid, slotted spoon

Poaching is an exercise in restraint. It is the art of cooking food gently in liquid held just below a simmer (around 75°C). It is the ideal method for delicate structures, fish, eggs, stone fruit, because the gentle heat preserves texture and requires no fat.

Because the liquid imparts the seasoning, build a court-bouillon, a brief broth of aromatics, acid, and herbs, to gently flavour the ingredient as it cooks.

The Most Common Mistake

Allowing the liquid to boil. Boiling tightens the protein fibres instantly, wringing out the moisture and leaving you with dry, chalky fish. Keep the water at a barely perceptible tremble.

Salmon Poached in Court-Bouillon

Serves 4 | 20 min prep | 30 min cook

Ingredients

  • 4 skinless salmon fillets, ~150g each
  • 1 carrot, 1 celery stick, 1 onion (sliced)
  • 1 bay leaf, 6 black peppercorns
  • 100ml dry white wine & ½ lemon, sliced
  • Parsley stalks
  • 4 leeks, halved lengthways
  • 600g new potatoes
  • 30g flat-leaf parsley & 15g basil
  • 1 tbsp capers, 4 anchovy fillets, 1 garlic clove
  • 1 tsp Dijon mustard
  • 1 tbsp red wine vinegar
  • 4 tbsp extra-virgin olive oil

Method

  1. 1Combine the carrot, celery, onion, bay, peppercorns, wine, lemon, and parsley stalks in a wide pan with 1.5 litres of water. Simmer for 15 minutes to extract the flavours, then drop the heat until the water is barely trembling.
  2. 2Boil the potatoes for 15 minutes. Gently steam or simmer the leeks for 6-8 minutes until tender.
  3. 3Hand-chop the parsley, basil, capers, anchovies, and garlic on a board. Transfer to a bowl and fold in the mustard, vinegar, and olive oil to create a textured salsa verde.
  4. 4Gently lower the salmon into the court-bouillon. The liquid must remain completely still.
  5. 5Poach for 8-10 minutes. For the most delicate texture, turn the heat off completely and let the fish steep for 12 minutes. It is ready when the flesh yields under light pressure.
  6. 6Lift out with a slotted spoon, blot on paper towels, and serve alongside the vegetables and salsa verde.

Mastering the Sauce: Salsa verde

A vibrant suspension of chopped herbs, capers, garlic, and acid. Always chop this by hand; a food processor oxidises the herbs and turns a bright, rustic sauce into a muddy paste.

Application: Toss through warm new potatoes, spoon over grilled root vegetables, or serve alongside a freshly poached egg.

05. Steaming

The Meal:
Steamed Sea Bass with Ginger & Spring Onion
The Sauce:
Ginger and spring onion hot oil
Skill level
Easy
Equipment
Wok or wide pan with a lid, steamer rack, heatproof plate

Steaming uses the vapour suspended above boiling water. Because the temperature never exceeds 100°C, the cooking process is gentle, exceptionally clean, and requires no fat.

The cardinal rule is that the food must never touch the water. Keep the water at a rolling boil to ensure a continuous column of steam.

The Most Common Mistake

Lifting the lid. Every time you peek, you dump the ambient heat, halting the cooking process. Fish and dumplings are unforgiving of these temperature fluctuations. Trust your timing and check only at the end.

Steamed Sea Bass with Ginger & Spring Onion

Serves 4 | 15 min prep | 15 min cook

Ingredients

  • 4 sea bass fillets, ~130g each
  • Thumb of ginger (half sliced, half julienned)
  • 6 spring onions (julienned)
  • 1 tbsp Shaoxing wine
  • 2 tbsp light soy sauce & 1 tsp caster sugar
  • 3 tbsp groundnut or neutral oil
  • 300g pak choi, halved & 200g jasmine rice

Method

  1. 1Lightly season the fish with salt and Shaoxing wine. Lay the sliced ginger and half the spring onions on a heatproof plate, resting the fish on top to allow steam to circulate underneath.
  2. 2Bring 3cm of water to a rolling boil in a wok fitted with a rack. Lower the plate in, seal tightly with a lid, and steam over high heat for 8-10 minutes.
  3. 3Blanch the pak choi in boiling water for 90 seconds and drain.
  4. 4The fish is done when it is entirely opaque and flakes easily. Carefully discard any cloudy water that has pooled on the plate.
  5. 5Blanket the fish with the remaining julienned ginger and spring onion. Dissolve the sugar into the soy sauce and pour it around the base of the fish.
  6. 6Heat the oil in a small pan until smoking. Pour it directly over the ginger and spring onion. The aromatics will hiss and wilt instantly, infusing the oil. Serve immediately.

Mastering the Sauce: Ginger and spring onion hot oil

A classic Cantonese technique where smoking-hot oil is poured over raw aromatics. The instant heat flash-cooks the ginger and alliums, carrying their fragrant oils across the dish.

Application: Use this exact finish over blanched broccoli, steamed pak choi, or a simple bowl of noodles.

06. Braising

The Meal:
Braised Lamb with White Beans
The Sauce:
Gremolata
Skill level
Moderate
Equipment
Heavy casserole with a tight lid, tongs, wooden spoon

Braising is the alchemy of heat, moisture, and time. It involves heavily searing an ingredient, then cooking it slowly in a shallow, covered pool of liquid. It is the definitive technique for transforming tough, hardworking cuts (or dense vegetables) into something yielding and gelatinous.

The liquid should reach no higher than halfway up the ingredient. The submerged portion simmers, while the exposed portion gently steams.

The Most Common Mistake

Rushing the sear. The deeply caramelised residue left in the pan (the fond) is the foundation of your braise's flavour. Brown in uncrowded batches until the surface is genuinely dark. You shouldn't add the liquid until a proper crust has formed.

Braised Lamb with White Beans

Serves 4 | 20 min prep | 140 min cook

Ingredients

  • 600g lamb shoulder, trimmed and cut into 4cm pieces
  • 1 tbsp olive oil & 1 onion, diced
  • 2 garlic cloves, sliced & 1 tsp fennel seeds
  • 2 anchovy fillets
  • 200ml dry white wine
  • 400g tin chopped tomatoes
  • 300ml stock
  • 1 sprig rosemary
  • 400g tin cannellini beans, drained
  • Zest of 1 lemon, 20g flat-leaf parsley, 1 small garlic clove (for gremolata)

Method

  1. 1Heat the oven to 150°C (130°C fan). Aggressively pat the lamb dry and season well.
  2. 2Heat the oil in a heavy casserole. Brown the lamb in batches for 5-6 minutes until a dark crust forms. Remove to a plate.
  3. 3Reduce the heat. Sweat the onion for 5 minutes, then bloom the garlic, fennel seeds, and anchovies for 1 minute.
  4. 4Deglaze with the wine, scraping the caramelised fond from the base. Reduce for 2 minutes.
  5. 5Return the lamb to the pot. Add the tomatoes, stock, and rosemary. The liquid should cover half the meat. Bring to a gentle simmer, cover, and transfer to the oven for 2 hours until the lamb is fork-tender.
  6. 6Fold in the beans and cook uncovered for a final 15 minutes. Skim away surface fat.
  7. 7Finely chop the lemon zest, parsley, and raw garlic to make the gremolata, scattering it over the dish just before serving.

Mastering the Sauce: Gremolata

Long, slow braises result in incredibly deep but heavy flavours. Gremolata, a raw, sharp garnish of zest, garlic, and parsley, acts as a culinary corrective, cutting through the richness and waking the palate up.

Application: Scatter over any slow-cooked stew, roasted aubergine, or fold into a rich lentil ragù.

07. Stir-Frying

The Meal:
Prawn and Green Bean Stir-Fry
The Sauce:
The master stir-fry glaze
Skill level
Moderate
Equipment
Wok or wide heavy skillet, wok ladle or spatula

Stir-frying relies on thermal momentum: small, uniform pieces of food kept in constant motion over aggressive, searing heat. Because the process is over in minutes, your mise en place must be flawless. If your sauce isn't mixed before the pan gets hot, you shouldn't start cooking.

The hallmark of a great stir-fry is wok hei, the "breath of the wok", which occurs when atomised oil droplets catch the intense heat of the pan, imparting a distinct, smoky sear.

The Most Common Mistake

Cooking everything at once. Dumping a mound of cold ingredients into a pan instantly kills the heat. The ingredients drop their water, pool in the centre, and boil. Work in small, fiercely hot batches.

Prawn and Green Bean Stir-Fry

Serves 4 | 20 min prep | 10 min cook

Ingredients

  • 500g raw king prawns, peeled and deveined
  • 300g green beans, halved
  • 1 red pepper, sliced
  • 4 garlic cloves, sliced & thumb of ginger, julienned
  • 2 dried red chillies, torn & 1 tsp Sichuan peppercorns
  • 3 spring onions, cut into batons
  • 250g medium egg noodles
  • 2 tbsp groundnut oil
  • 3 tbsp light soy sauce, 1 tbsp Chinkiang black vinegar, 1 tsp caster sugar, 1 tsp cornflour, 4 tbsp water

Method

  1. 1Mix the soy, vinegar, sugar, cornflour, and water in a small jug. Place it by the hob with all your prepped ingredients.
  2. 2Cook and drain the noodles, tossing with a drop of oil to prevent sticking.
  3. 3Pat the prawns entirely dry to ensure they sear rather than steam.
  4. 4Heat a wok or heavy skillet until faintly smoking. Add half the oil, then the prawns in a single layer. Leave untouched for 45 seconds to sear, then toss for 1 minute. Remove to a plate while slightly undercooked.
  5. 5Add the remaining oil, green beans, and pepper. Stir-fry aggressively for 3 minutes until the vegetables blister but retain their snap.
  6. 6Add the garlic, ginger, chillies, and peppercorns. Toss for 30 seconds until fragrant, ensuring the garlic does not burn.
  7. 7Return the prawns. Stir the reserved sauce and pour it into the wok, tossing for 1 minute until it tightens into a glossy glaze. Fold in the noodles and spring onions, toss once more, and serve immediately.

Mastering the Sauce: The master stir-fry glaze

Memorise the ratio, not the recipe: three parts soy sauce, one part black vinegar, a touch of sugar for balance, and cornflour slaked in cold water to bind it to the ingredients.

Application: Dress cold smashed cucumbers, use as a dumpling dip, or use as the base for an aubergine and tofu stir-fry.

Common questions

Why focus on these seven techniques?

Knife skills, searing, roasting, poaching, steaming, braising, and stir-frying cover the full spectrum of dry heat, moist heat, and combination cooking. Master these, and you can execute almost anything a domestic kitchen requires. Grilling, baking, and deep-frying are intentionally omitted, as they require specialised setups or are expansive enough disciplines to warrant their own dedicated study.

Do I need to learn them in order?

While not mandatory, the curriculum is designed to build intuition. It progresses from ambient preparation to dry heat, gentle wet heat, combination methods, and culminates in the aggressive heat management of stir-frying. If you are already comfortable searing, skip to a technique that challenges you.

What equipment is actually essential?

You need remarkably little: a sharp chef's knife, a heavy-bottomed pan that retains thermal mass (carbon steel, cast iron, or thick stainless steel), a heavy casserole dish with a tight lid, and a basic steaming setup (a plate balanced on a heatproof bowl inside a lidded pot works perfectly).

How do I apply this to the Mello app?

Mello allows you to take any recipe you love, from any source, import it and easily order ingredients. You can also adapt recipes as you learn how to cook; and save these to your own personal cookbook. Our dream is to make cooking more fun for people who love food.
