Ingredients
For the chicken
- 4 large chicken breasts , skin-on
- 1 tsp sea salt
- ½ tsp black pepper
- 1 tbsp olive oil , or as needed
- 1 tbsp unsalted butter
For the sauce
- 2 tbsp unsalted butter
- 3 large onions , cut into thin slices
- ½ tsp sea salt
- ½ tsp black pepper
- 1 tbsp fresh thyme , plus extra to serve
- 2 tsp light brown sugar
- ½ tbsp Dijon mustard
- 3 cloves garlic , sliced or minced
- ⅓ cup (80ml) Marsala , sherry or dry white wine
- 1 tbsp flour
- 2 cups (500ml) chicken broth
- ⅓ cup (80ml) cream heavy / double
- gruyere cheese , grated to serve
Instructions
- Pat the chicken breasts dry using paper towels and season well with sea salt and black pepper.
- Heat oil and butter in a large casserole dish. Place the chicken breasts in the hot pan, skin-side down. Cook for 4-5 minutes or until the skin is deeply golden then turn over and cook the underside for a couple of minutes. Transfer the chicken onto a plate and set aside.
- Add the sliced onions and season with salt and pepper. Cook over high heat, stirring until they start to brown.
- Sprinkle with the sugar and thyme, add the wine, cover with a lid (a glass one if possible so you can check on the onion's progress) and sweat the onions for 20 minutes or so, stirring occasionally.
- Remove the lid and cook for 15 minutes, stirring frequently, until the onions are very soft and golden.
- Add the butter, garlic, Dijon mustard and flour and stir well, cooking for a minute or so. Gradually stir in the chicken broth and bring to a simmer.
- Reduce the heat, return the chicken breasts and their juices to the pan and cover with a tight fitting lid. Cook for 6-9 minutes, depending on their thickness, or until cooked through (165°F /75°C on a meat thermometer). Set chicken aside onto a plate.
- Stir in the cream and check the seasoning, adding salt and pepper if needed. Serve the chicken breasts over mashed potatoes, rice or noodles with a generous grating of Gruyere cheese and a sprinkling of fresh thyme leaves.

Notes
- You use beef broth instead of chicken for a richer, darker gravy.
- Make sure the chicken breasts are of equal size and thickness so that they cook at the same time. You don't want to overcook them so a meat thermometer is very useful here!
- Slice a baguette and brush with olive oil on both sides. Toast in the oven or air fryer for 10-15 minutes at 350°F /180°C. Brush with Dijon mustard and top with grated Gruyere. Place under the broiler (grill) to melt the cheese to serve alongside the chicken.
