Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

cooked chicken breast, shredded or diced
broccoli florets
heavy cream
cream cheese
garlic, minced
parmesan cheese, grated
mozzarella cheese, shredded
butter
Italian seasoning
salt
black pepper

Directions

I start by preheating the oven to 375°F (190°C) and lightly greasing a baking dish.

Next, I prepare the Alfredo sauce. In a saucepan over medium heat, I melt the butter and cook the minced garlic until fragrant.

I add the heavy cream and cream cheese, stirring until the mixture becomes smooth and creamy.

Then I mix in grated parmesan cheese, Italian seasoning, salt, and black pepper, letting the sauce simmer gently until it thickens slightly.

In a large bowl, I combine the cooked chicken and broccoli florets. I pour the Alfredo sauce over the mixture and stir until everything is well coated.

I transfer the mixture into the prepared baking dish and spread it evenly.

I sprinkle shredded mozzarella cheese over the top of the casserole.

I bake the casserole for about 20 to 25 minutes, until the cheese is melted and bubbly.

After baking, I let the casserole rest for a few minutes before serving.

Servings and Timing

This recipe usually makes about 6 servings.

Preparation time: 10 minutes
Cooking time: 25 minutes
Total time: about 35 minutes

Variations

I sometimes add mushrooms or spinach to the casserole for extra flavor and nutrients.

Another variation I enjoy is replacing the broccoli with cauliflower, which works well with the creamy Alfredo sauce.

For a slightly richer flavor, I occasionally add a small amount of cooked bacon or crispy pancetta to the mixture.

storage/reheating

I store leftover casserole in an airtight container in the refrigerator for up to 4 days.

To reheat, I warm portions in the oven at 350°F (175°C) for about 10 minutes or until heated through.

I can also reheat individual servings in the microwave for a quicker option.

The casserole can also be frozen for up to 2 months. I thaw it in the refrigerator before reheating.
