Ingredients

- 3 –4 garlic cloves minced

Instructions
- Prep chicken: Pat dry and season both sides with salt, pepper, and herbs.
- Sear chicken: In a skillet with 1 tbsp oil, sear 2–3 minutes per side until golden. Remove and set aside.
- Cook mushrooms: Add remaining oil, sauté mushrooms 5–7 minutes until browned. Add garlic in the last minute.
- Wilt spinach: Add spinach in batches, stirring until wilted. Remove from heat.
- Mix sauce: In a bowl, combine cream, Dijon, Parmesan, and ¾ of the mozzarella. Stir in seasoning.
- Assemble dish: Spread some sauce in a casserole dish. Layer half the spinach-mushroom mix, then chicken, then remaining veggies. Pour sauce over and top with mozzarella.
- Bake: Cover loosely with foil, bake at 375°F (190°C) for 20–25 minutes. Uncover and bake 8–10 minutes more until cheese is bubbly and chicken reaches 165°F (74°C).
- Rest and serve: Let sit for 5 minutes before serving. Garnish with parsley or extra Parmesan.
