Servings: 6
Ingredients
2 tablespoons butter or olive oil
1 ½ pounds boneless, skinless chicken breasts, cubed
1 teaspoon garlic powder
Salt and pepper to taste
1 ½ cups broccoli florets
1 small zucchini, sliced
1 cup sliced mushrooms
1 cup spinach leaves
1 cup heavy cream
1 cup shredded mozzarella cheese
½ cup grated parmesan cheese
2 ounces cream cheese
½ teaspoon paprika
Chopped parsley, for garnish
Step-by-Step Instructions
1. Cook the chicken
Preheat oven to 375°F (190°C). In a skillet, melt butter over medium heat. Add chicken, garlic powder, salt, and pepper. Cook until lightly browned and cooked through, about 6–8 minutes. Transfer to a casserole dish.
2. Sauté the vegetables
In the same skillet, add broccoli, zucchini, and mushrooms. Sauté for 4–5 minutes until tender. Add spinach and cook until wilted. Add vegetables to the casserole dish with the chicken.
3. Make the creamy sauce
Reduce heat to low and pour in heavy cream. Add mozzarella, parmesan, and cream cheese. Stir until melted and smooth. Season with paprika, salt, and pepper to taste.
4. Assemble and bake
Pour the creamy sauce over the chicken and vegetables. Stir to combine, then bake uncovered for 15–20 minutes until bubbly and golden on top.
5. Serve
Garnish with chopped parsley and serve warm.

Can I freeze this casserole?
