Instructions

  1. Pat the chicken breasts dry using paper towels and season well with sea salt and black pepper.
  2. 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.
  3. Add the sliced onions and season with salt and pepper. Cook over high heat, stirring until they start to brown.
  4. 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.
  5. Remove the lid and cook for 15 minutes, stirring frequently, until the onions are very soft and golden.
  6. 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.
  7. 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.
  8. 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.
