Flavorful Baked Chicken with Creamy Mushroom Sauce

This dish features chicken breasts baked to perfection, topped with caramelized onions and mushrooms, all enveloped in a creamy garlic-herb sauce. The recipe takes about 1 hour from start to finish and serves 4 people.
Ingredients
- 4 boneless, skinless chicken breasts
- 2 cups sliced mushrooms (such as cremini or button)
- 2 large onions, thinly sliced
- 4 cloves garlic, minced
- 1 cup heavy cream (or coconut milk for dairy-free option)
- 1 tablespoon olive oil
- 1 tablespoon butter (or dairy-free butter)
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- Salt and pepper to taste
- Fresh parsley for garnish (optional)
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C).
- Sauté the Onions: In a large skillet, heat olive oil and butter over medium heat. Add the sliced onions and cook, stirring occasionally, until they are caramelized and golden brown, about 15-20 minutes. Remove from the skillet and set aside.
- Cook the Mushrooms: In the same skillet, add the sliced mushrooms and garlic. Sauté until the mushrooms are browned and tender, about 5-7 minutes. Season with thyme, rosemary, salt, and pepper.
- Prepare the Cream Sauce: Reduce the heat to low and stir in the heavy cream (or coconut milk). Let it simmer for a few minutes until slightly thickened. Adjust seasoning as needed.
- Assemble the Dish: In a baking dish, place the chicken breasts and season with salt and pepper. Pour the mushroom and cream sauce over the chicken, then top with the caramelized onions.
- Bake: Cover the dish with foil and bake in the preheated oven for 25-30 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
- Serve: Garnish with fresh parsley if desired and serve hot.
