Directions

Preheat oven: Set oven to 375°F (190°C).
Brown the chicken: Heat oil or butter in a large oven-safe skillet or Dutch oven. Season chicken with salt and pepper, and brown on both sides until golden, about 4-5 minutes per side. Remove and set aside.
Sauté vegetables: In the same pan, add sliced onions and mushrooms. Cook until softened and lightly browned, about 7-8 minutes. Add minced garlic and cook for another minute.
Make the sauce: Stir in chicken broth, Dijon mustard, and herbs. Bring to a simmer and let reduce slightly.
Add cream: Stir in heavy cream or crème fraîche and simmer until the sauce thickens.
Combine and bake: Return chicken to the pan, spoon sauce over the top. Transfer the skillet or casserole dish to the oven and bake for 25-30 minutes until chicken is cooked through.
Garnish and serve: Sprinkle with fresh parsley and serve hot with crusty bread or roasted potatoes.
