Ingredients
600g Chicken breasts, halved if thick
300g Chestnut or button mushrooms, sliced
1 medium Onion, finely sliced
2 cloves Garlic, crushed
2 tbsp Olive oil
15g Unsalted butter
2 tbsp Dijon mustard
150ml Single cream
150ml Chicken stock
small handful Fresh thyme
1 tsp Cornflour, mixed with 1 tbsp cold water (optional, to thicken sauce)
1/2 tsp Sea salt (plus extra to taste)
1/2 tsp Black pepper, freshly ground
small handful Fresh parsley, chopped
a squeeze of Lemon juice
Method
Step 1
Pat the chicken dry and season both sides with half the salt and pepper.
Step 2
Heat the olive oil and butter in a large frying pan over medium-high heat. When hot, add the chicken and cook for 3-4 minutes per side until golden-brown. Remove the chicken to a plate; it will finish cooking in the sauce.
Step 3
Reduce the heat to medium and add the sliced onion and mushrooms to the pan. Cook for 6-8 minutes, stirring occasionally, until softened and the mushrooms release their juices.
Step 4
Add the garlic and thyme and cook for 30-60 seconds until fragrant.
Step 5
Stir in the Dijon mustard, then pour in the chicken stock, scraping the base of the pan to loosen any browned bits. Simmer for 2-3 minutes.
Step 6
Pour in the single cream and return the chicken to the pan. Bring to a gentle simmer, cover and cook for 6-8 minutes until the chicken is cooked through (internal temperature 75ºC) and the sauce has thickened slightly.
Step 7
If the sauce is too thin, stir the cornflour slurry and add a little at a time, simmering until the sauce reaches the desired consistency. Adjust seasoning with the remaining salt and pepper and add the lemon juice if using.
Step 8
Serve the chicken topped with the mushroom sauce and scatter with chopped parsley. Good with steamed greens, mashed potato or rice.

Recipe Notes
For a lighter version use reduced‑fat single cream and omit the butter. If you prefer breasts to remain extra juicy, finish the pan in a preheated oven at 180ºC for 5-6 minutes.
