Ingredients
Serves 6
- 2 lb (900g) boneless, skinless chicken breast or thighs, cut into bite-size pieces
- 2 tablespoons olive oil
- 1 medium onion, sliced (optional)
- 3 cups (240g) mushrooms, sliced
- 3–4 cups (120–160g) fresh spinach
- 3 cloves garlic, minced
- 1 teaspoon salt (adjust to taste)
- 1/2 teaspoon black pepper
- 1 teaspoon Italian seasoning
- 1/2 teaspoon paprika (optional)
Creamy Sauce
- 1 cup (240ml) heavy cream (or use half-and-half for lighter)
- 1/2 cup (120ml) chicken broth
- 4 oz (113g) cream cheese, softened
- 1/2 cup (50g) grated Parmesan
- 1 1/2 cups (150g) shredded mozzarella
Optional add-ins:
- 1/2 teaspoon red pepper flakes (for heat)
- 1 tablespoon lemon juice (for brightness)
- 1/4 cup chopped sun-dried tomatoes (for extra flavor)
Preparation Time
- Prep time: 15 minutes
- Cooking time: 30–35 minutes
- Total time: About 50 minutes
Step-by-Step Instructions
Step 1: Preheat and Prep
Preheat oven to 400°F (200°C). Grease a 9×13-inch baking dish or spray with cooking spray.
Step 2: Sauté the Mushrooms
In a large skillet over medium-high heat, warm olive oil. Add mushrooms (and onion if using) and cook for 6–8 minutes until browned. Stir in garlic for 30 seconds.
Step 3: Make the Creamy Sauce
Lower heat to medium. Add chicken broth, heavy cream, and cream cheese. Stir until cream cheese melts and the sauce is smooth.
Mix in Parmesan, salt, pepper, Italian seasoning, and paprika.
Step 4: Add Chicken and Spinach
Add chicken pieces to the skillet and stir to coat (they will finish cooking in the oven). Fold in spinach until it starts to wilt.
Step 5: Bake
Pour everything into the baking dish. Top with mozzarella.
Bake for 25–30 minutes, until chicken is fully cooked and the top is bubbly and lightly golden.
Step 6: Rest and Serve
Let rest for 5 minutes before serving so the sauce thickens slightly.
Serving Suggestions
- Serve over cauliflower rice, zucchini noodles, or sautéed cabbage.
- Pair with a simple salad and olive oil dressing.
- Add roasted broccoli or asparagus on the side.
- For non–low carb guests, serve with crusty bread or rice (optional).
- Top with fresh parsley and extra Parmesan for a pretty finish.
