Serves 4Prep 15 minCook 30 minTotal 45 min

Ingredients

• 4 small boneless, skinless chicken breasts, approximately 700g total
• 1 teaspoon fine salt, divided
• ½ teaspoon freshly ground black pepper, divided
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 300g cremini or chestnut mushrooms, cleaned and sliced
• 1 small shallot, finely chopped
• 3 garlic cloves, finely minced
• 1 tablespoon plain flour
• 300ml chicken stock
• 180ml double cream
• 1 teaspoon Dijon mustard
• 1 teaspoon fresh thyme leaves, plus extra to serve
• 1 tablespoon chopped fresh parsley
• 1 teaspoon lemon juice

Method

1. Prepare the chicken. Pat the chicken breasts dry with kitchen paper. If they are very thick, slice them horizontally into thinner pieces so they cook evenly. Season both sides with half of the salt and pepper.
2. Sear the chicken. Heat the olive oil in a large skillet over medium-high heat. Add the chicken and cook for 3–5 minutes on each side, until golden brown. The chicken does not need to be fully cooked at this stage. Transfer it to a plate.
3. Brown the mushrooms. Reduce the heat to medium and add the butter. Once melted, add the sliced mushrooms in a single layer. Cook for 5–7 minutes, stirring occasionally, until the mushrooms are browned and their moisture has evaporated.
4. Add the aromatics. Stir in the shallot and cook for 2 minutes. Add the garlic and cook for a further 30 seconds. Do not allow the garlic to brown heavily.
5. Thicken the base. Sprinkle the flour over the mushrooms and stir until evenly combined. Cook for 1 minute to remove the raw flour flavour.
6. Make the sauce. Pour in the chicken stock gradually, stirring continuously and scraping the browned pieces from the bottom of the skillet. Add the double cream, Dijon mustard and thyme. Stir until smooth.
7. Finish the chicken. Return the chicken and any accumulated juices to the skillet. Reduce the heat to medium-low. Cover loosely and simmer for 8–12 minutes, turning the chicken once, until cooked through and the sauce has thickened.
8. Check the temperature. Insert an instant-read thermometer into the thickest part of the largest chicken piece. It should register 74°C . If the chicken is not at this temperature, continue cooking and check again after 2 minutes.
9. Finish and serve. Remove the skillet from the heat. Stir in the lemon juice and taste the sauce. Adjust the seasoning if required. Scatter over the parsley and additional thyme, then serve immediately.

One-Pot Creamy Mushroom Chicken Skillet

Tender chicken, browned mushrooms and a smooth garlic cream sauce come together in one pan. This creamy mushroom chicken skillet is suitable for a weeknight dinner and requires no separate saucepans.

The chicken is seared first for colour, then finished gently in the sauce. The mushrooms absorb the pan juices while chicken stock, cream and Dijon mustard create a balanced sauce without complicated preparation.

Overview

This recipe serves four people and works with either chicken breasts or boneless chicken thighs. Chicken breasts provide a leaner result, while thighs remain particularly moist during simmering.

Use a large, heavy-based skillet so the chicken and mushrooms have enough room to brown. Overcrowding the pan can cause the mushrooms to steam rather than develop a deeper flavour.

The finished dish can be served with mashed potatoes, rice, pasta, crusty bread or steamed vegetables.

Tips

Dry the chicken before seasoning

Surface moisture prevents proper browning. Patting the chicken dry helps it develop a more even golden exterior.

Avoid overcrowding the skillet

If the chicken pieces are large or the skillet is small, sear them in batches. Overcrowding lowers the pan temperature and can leave the chicken pale.

Brown the mushrooms properly

Mushrooms release water as they cook. Continue cooking until that water has evaporated and the mushrooms begin to brown before adding the shallot or stock.

Use a gentle simmer

Cream sauces can separate when boiled aggressively. Keep the sauce at a gentle simmer, particularly after returning the chicken to the pan.

Check chicken doneness with a thermometer

Colour is not a reliable measure of doneness. The thickest part of the chicken should reach 74°C. The USDA-referenced cooking guidance used in similar skillet preparations also emphasises checking the internal temperature rather than relying on appearance alone.

Variations

Use chicken thighs

Replace the chicken breasts with boneless, skinless chicken thighs. They may require a few additional minutes of simmering, depending on their size.

Add spinach

Stir two large handfuls of baby spinach into the finished sauce. Cook for 1–2 minutes, until wilted.

Add Parmesan

Stir 40g of finely grated Parmesan into the sauce after removing the skillet from the heat. Reduce the added salt because Parmesan is naturally salty.

Make it alcohol-free

This recipe does not require wine. Chicken stock provides enough liquid for the sauce and allows the dish to remain suitable for a family dinner.

Serve it with pasta

Slice the cooked chicken and toss the sauce with cooked tagliatelle or penne. For a dedicated pasta version, see this one-pot creamy chicken and mushroom pasta recipe.

Make it lighter

Use half-and-half or a reduced-fat cooking cream instead of double cream. The sauce will be less rich and may require a slightly longer simmer to thicken.

Serving suggestions

Serve the skillet with mashed potatoes, steamed green beans, rice or roasted vegetables. Crusty bread is useful for collecting the remaining sauce.

For a more substantial meal, spoon the chicken and mushrooms over buttered noodles or cooked rice. Add a simple green salad dressed with lemon juice and olive oil to offset the richness of the cream sauce.

Storage and reheating

Transfer leftovers to a shallow airtight container and refrigerate within two hours. Use within three days.

Reheat gently in a covered skillet over low heat with a small splash of stock or water. Stir occasionally until the chicken and sauce are hot throughout. Avoid prolonged high heat, which can cause the cream sauce to split and the chicken to become dry.

Do not reheat the same portion more than once.

FAQ

Can I use chicken thighs instead of chicken breasts?

Yes. Boneless, skinless chicken thighs work well and are less likely to dry out. Check the thickest piece with a thermometer and continue cooking until it reaches 74°C.

Can I make this recipe without flour?

Yes. Omit the flour and simmer the stock and cream for several additional minutes. The sauce will be slightly thinner. You can also mix 1 teaspoon of cornflour with 2 teaspoons of cold water and stir it into the simmering sauce.

Why is my mushroom sauce watery?

The mushrooms may not have cooked long enough before the stock was added. Continue simmering uncovered until the sauce reduces. Avoid adding extra salt before the mushrooms have browned, as salt can draw out additional moisture.

Can I use milk instead of cream?

Milk can be used, but the sauce will be thinner and less rich. For a more stable result, use half-and-half or add a small amount of flour or cornflour.

Is this recipe suitable for meal preparation?

Yes. Store the chicken and sauce in sealed containers for up to three days. Reheat gently with a splash of stock to loosen the sauce.

What is the safest way to cook the chicken?

Cook the chicken until the thickest part reaches 74°C. Check the largest piece with an instant-read thermometer, avoiding contact with the pan.
