Gather fresh produce, measure your storecupboard items and prep the ovenproof dish before you begin.

Fresh Produce

Baby new potatoes: 350g–900g, halved or quartered if large. Boil for 12 minutes to achieve the ideal texture.

Three large leeks, washed and sliced, add sweetness. Use plenty of fresh thyme leaves; 1 tsp dried thyme works as a substitute.

Pantry Staples

For the sauce, you need 40g plain flour and 40g butter to make a roux, plus 600ml chicken stock. Season with salt pepper and freshly ground black pepper.

A large pan is useful for browning the breasts before transferring everything to a 2.3 litre ovenproof dish for the final bake.

• Six skinless, boneless breasts (as per the complete aga cookbook).
• Fresh thyme leaves or dried thyme if fresh is unavailable.
• High-quality salt and freshly ground black pepper for seasoning.

Preparing the Vegetables and Chicken

Start by readying the veg and pan so timing stays precise and flavours build.

Bring a large pan of water to the boil and add your baby new potatoes. Boil for 12 minutes, then add the leeks for the final 3 minutes so the potatoes tender and the leeks remain bright.

Techniques for Browning Chicken

Use a large frying pan and heat a little oil large frying until shimmering. Season the breasts with salt pepper and freshly ground black pepper.

Brown the chicken for 2–3 minutes per side with a drizzle honey to promote a golden crust. Once you brown chicken, remove each piece with a slotted spoon and set aside.

Do not wash the pan — those browned bits will enrich the sauce. Drain the leeks and potatoes well in a colander before mixing with the creamy herb sauce later.

• Bring water boil, add baby new potatoes for 12 minutes.
• Add leeks for the last 3 minutes so vegetables are tender.
• Use a large frying pan and oil large frying to brown chicken quickly.
• Season with freshly ground black and salt pepper; set aside after browning.

Tip: Have foil ready to cover the assembled dish before it goes in the oven. For a full step-by-step method and timing, see the Mary Berry chicken and leek pie with potato.

Creating the Creamy Herb Sauce

Use the flavours left in your frying pan as the base for a silky, herb-scented sauce.

In the same large frying pan, melt the butter in the unwashed pan. Stir in the plain flour to make a smooth roux and cook for a minute to remove the raw taste.

Gradually whisk in the chicken stock so the sauce stays lump-free. Keep stirring until it begins to thicken and you can bring boil the mixture briefly.

Add the crème fraîche and fresh thyme leaves, then season with salt pepper to taste. Stir until the sauce is glossy and coats a spoon.

Remove the pan from the heat and fold in the drained leeks and potatoes. Gently mix so the vegetables are fully coated before you transfer everything into the buttered ovenproof dish.

Arrange the browned breasts evenly on top, then set aside for a moment if you want to check seasoning. Using the same pan captures the browned juices — a classic tip from the complete aga cookbook and the aga cookbook style that helps build depth.

Assembling and Baking the Dish

Careful assembly makes the difference: spread the leeks and potatoes evenly, then rest each browned breast on top so every portion gets sauce and herbs.

Cover the dish tightly with foil, sealing the edges to trap steam. Bake in a preheated oven at 200°C (Fan 180°C) or Gas 6 for 25 minutes to let the flavours meld and the sauce bubble.

Remove the foil and continue to cook for a further 8–10 minutes until the top is golden and the drizzle honey on the breasts begins to caramelise. The total oven time is about 35 minutes, which should leave the potatoes tender.

• Place the browned chicken breasts over the sauced vegetables so heat distributes evenly.
• Seal the foil edges tightly to ensure the breasts stay moist while they cook.
• Bake at 200°C/Fan 180°C/Gas 6 for 25 minutes, then remove foil and cook 8–10 minutes more.
• Monitor gas minutes if using a gas oven to avoid the sauce drying out too quickly.

Check the dish is ready by ensuring the juices run clear and the sauce is bubbling. This is the simple indicator that the chicken cooked through and the potatoes are heated perfectly.

Expert Tips for Success

Timing and little techniques are the real secret to a fuss-free supper. Follow simple rules and you will avoid common pitfalls and serve a dish that feels effortless.

Avoiding Overcooked Potatoes

Stick to the 12-minute boil for new potatoes and add leeks only for the last 3 minutes. The veg will continue to soften in the oven, so this step keeps them firm.

Brown chicken first to lock in juices. This ensures the breasts retain texture while the vegetables finish in the oven.

Achieving the Perfect Sauce Consistency

If the sauce seems thin, make sure you cooked the roux for at least one full minute before adding stock.

Whisk the stock in gradually and simmer until it coats the spoon. Remove foil after the sealed bake to let the top caramelise and the sauce reduce slightly.

Storing and Freezing Leftovers

Store leftovers in the fridge for up to three days. For longer storage, freeze the base without the potatoes for up to two months.

When reheating, cover with foil to keep the breasts moist and reheat gently in the oven until the chicken is fully warmed through.

“Proper timing is the secret to this recipe; always keep an eye on the cook minutes to ensure the chicken is perfectly tender.”

• Brown chicken before baking for best flavour and colour.
• Monitor your oven and adjust gas minutes when using a gas oven to keep results consistent.
• Use a thermometer to confirm the chicken cooked through if in doubt.

Serving Suggestions and Pairings

Pairing matters: choose bright vegetables and plain bread to highlight the herb sauce and tender meat.

Serve the dish with steamed green vegetables such as broccoli or green beans. These add colour and freshness and cut through the creaminess.

A crisp, crusty loaf is ideal for mopping up the sauce. A slice of bread brings texture and makes every mouthful satisfying.

Winewise, a chilled Sauvignon Blanc complements the earthy notes of the fresh thyme and lifts the flavours on the plate.

• mary berry recommends greens to balance richness.
• Once you remove foil, the aroma of fresh thyme bursts free — serve straight away.
• A crisp salad or roasted carrots work well alongside the potatoes for variety.
• For a rustic finish, serve from the ovenproof dish so guests help themselves.

Allow the dish to rest for a few minutes before serving so the sauce thickens and flavours settle.
