Ingredients:
- 1 ½ lbs boneless, skinless chicken breasts (cut into bite-sized pieces)
- 2 tablespoons olive oil
- 1 tablespoon butter
- 1 medium onion, finely chopped
- 3 cloves garlic, minced
- 8 oz mushrooms, sliced
- 3 cups fresh spinach leaves
- 1 cup heavy cream
- ½ cup chicken broth
- 1 teaspoon Dijon mustard
- ½ teaspoon paprika
- ½ teaspoon dried thyme
- Salt and black pepper to taste
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- Fresh parsley, chopped (for garnish)
Instructions:
- Preheat the oven to 375°F (190°C) and lightly grease a baking dish with olive oil or nonstick spray.
- Cook the chicken: Heat olive oil in a large skillet over medium-high heat. Add chicken pieces, season with salt, pepper, and paprika, and cook until golden brown on all sides (about 5–6 minutes). Remove from the skillet and set aside.
- Sauté the vegetables: In the same skillet, melt butter. Add chopped onion and cook until translucent, about 3 minutes. Stir in the garlic and mushrooms, cooking until the mushrooms are golden and tender.
- Add spinach: Add fresh spinach leaves to the skillet and cook just until wilted.
- Make the creamy sauce: Pour in the heavy cream and chicken broth. Stir in Dijon mustard and thyme. Let the sauce simmer for 3–4 minutes until slightly thickened.
- Combine everything: Add the cooked chicken back into the skillet and stir until coated with the creamy mixture.
- Bake: Transfer the mixture to the prepared baking dish. Sprinkle mozzarella and Parmesan cheese evenly on top.
- Bake uncovered for 20 minutes or until bubbly and golden on top.
- Garnish & serve: Let cool for 5 minutes, then sprinkle with fresh parsley before serving.
Tips & Tricks:
- Use rotisserie chicken for an even quicker version.
- Substitute kale for spinach if you prefer a heartier green.
- Add a pinch of red pepper flakes for a little kick of heat.
- If you’re dairy-free, use coconut cream and dairy-free cheese alternatives — it still comes out rich and flavorful!
