Ingredients
  

Main Ingredients
  • 4 pieces boneless, skinless chicken breasts
  • 8 oz mushrooms, sliced (about 225 g)
  • 4 cups fresh spinach, roughly chopped
  • 1 cup shredded mozzarella or cheddar cheese
  • 1/2 cup grated Parmesan cheese
  • 1 cup heavy cream or half-and-half
Cooking Ingredients
  • 2 tablespoons olive oil
  • 2 cloves garlic, minced
  • 1 small onion, chopped
  • 1 teaspoon dried thyme or Italian seasoning
  • to taste Salt and black pepper
  • 1 tablespoon butter (optional)
  • 1 tablespoon flour (optional, to thicken)

Method
 

Preparation
  1. Preheat the oven to 375°F (190°C). Lightly grease a medium baking dish.
  2. Season the chicken breasts with salt, pepper, and half the thyme.
  3. Heat olive oil in a skillet over medium-high heat. Sear chicken 2–3 minutes per side until light brown. Remove and set aside.
  4. In the same skillet, add butter if using, then sauté onion until soft, about 3 minutes.
  5. Add garlic and mushrooms. Cook until mushrooms release liquid and turn golden, 5–6 minutes.
  6. Stir in the spinach and cook until wilted. If you want a thicker sauce, sprinkle flour and stir for 1 minute.
  7. Pour in the cream and bring to a light simmer. Add the remaining thyme, half the Parmesan, and taste for salt and pepper.
Baking
  1. Place chicken in the baking dish. Spoon the mushroom and spinach cream over the chicken. Sprinkle mozzarella and the rest of the Parmesan on top.
  2. Bake uncovered for 20–25 minutes, until the chicken reaches 165°F (74°C) and the top is golden.
  3. Let rest 5 minutes before serving.

Notes

Serve this bake hot with simple sides like steamed rice, mashed potatoes, or a green salad. Fresh bread also works well to soak up the sauce. Cut the chicken across the grain for tender slices.
