Ingredients
- 2 tablespoons olive oil
- 1 pound boneless, skinless chicken breasts, cut into bite-size pieces
- Salt and black pepper, to taste
- 8 ounces cremini or button mushrooms, sliced
- 3 cups fresh spinach
- 3 cloves garlic, minced
- ¾ cup heavy cream (or half-and-half for lighter version)
- 4 ounces cream cheese, softened
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- ½ teaspoon Italian seasoning
- ¼ teaspoon crushed red pepper flakes (optional)
Step-by-Step Instructions
- 1. Sauté the Chicken : Heat olive oil in a large skillet over medium heat. Season chicken with salt and pepper, then cook for 5–6 minutes until golden and just cooked through. Transfer to a plate.
- 2. Cook the Veggies : In the same pan, add mushrooms and sauté until browned and tender. Add garlic and spinach, stirring until spinach wilts.
- 3. Make the Creamy Sauce : Lower heat to medium-low. Add heavy cream and cream cheese, stirring until smooth and creamy. Sprinkle in Italian seasoning and crushed red pepper flakes for flavor.
- 4. Combine Everything : Return the cooked chicken to the pan and stir to coat in sauce. Mix in half of the mozzarella and Parmesan cheeses until well combined.
- 5. Bake Until Golden : Transfer the mixture to a lightly greased casserole dish. Top with remaining cheeses and bake at 375°F (190°C) for 20 minutes, or until the top is bubbly and golden brown.
- 6. Cool and Serve : Let rest for 5 minutes before serving. Each bite should be creamy, savory, and perfectly balanced — rich but light enough for a low-carb casserole night.
