How to Make Chicken Alfredo Biscuit Casserole

1. Preheat the Oven

Start by preheating your oven to 375°F (190°C). Lightly grease a medium-sized baking dish to prevent sticking.

2. Prepare the Chicken Mixture

In a large bowl, combine:

• cooked chicken

• Alfredo sauce

• garlic powder

• black pepper

• broccoli (if using)

Mix everything together until the chicken is evenly coated in the creamy sauce.

3. Add Cheese

Stir in half of the mozzarella cheese and half of the Parmesan cheese. This helps create a rich, cheesy filling inside the casserole.

4. Transfer to the Baking Dish

Spread the chicken Alfredo mixture evenly into the prepared baking dish.

Make sure the sauce covers the bottom evenly so the casserole stays moist while baking.

5. Prepare the Biscuit Topping

Cut each biscuit into four smaller pieces and place them on top of the chicken mixture.

Spread the biscuit pieces evenly across the casserole so they bake into a soft, golden topping.

6. Add the Remaining Cheese

Sprinkle the rest of the mozzarella and Parmesan cheese over the biscuit pieces. This creates a cheesy crust once baked.

7. Bake the Casserole

Place the dish in the oven and bake for 25–30 minutes, or until:

• the biscuits are golden brown

• the cheese is melted and bubbly

• the casserole is heated through

If the biscuits start browning too quickly, loosely cover the dish with foil for the remaining baking time.

8. Let It Rest and Serve

Allow the casserole to rest for 5 minutes after removing it from the oven. This helps the sauce thicken slightly and makes serving easier.

Scoop portions onto plates and enjoy while warm.
