My mother-in-law whipped this up last Sunday, and I could not believe how creamy and comforting it was. A total game changer that uses just 4 ingredients.

4-Ingredient Chicken Alfredo Biscuit Casserole
This easy Chicken Alfredo Biscuit Casserole turns a few simple ingredients into a warm and satisfying meal. Tender chicken and creamy Alfredo sauce form the base, while pieces of refrigerated biscuit dough bake into soft, fluffy bites with golden tops. A generous layer of mozzarella melts throughout the casserole, creating a rich and cheesy dish that combines the comfort of a classic pot pie with the flavors of a creamy pasta bake.
Ingredients
| Ingredient | Amount |
|---|---|
| Cooked chicken, shredded or chopped | 2 cups |
| Alfredo sauce | 2 cups (about 15–16 oz) |
| Refrigerated biscuit dough | 1 can (16.3 oz) |
| Mozzarella cheese, shredded and divided | 2 cups |
Instructions
Step 1: Prepare the Baking Dish
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Evenly spread 1 cup of the shredded mozzarella across the bottom of the dish.
Tip: The cheese layer on the bottom melts into the sauce as it bakes, adding extra flavor and helping create a delicious cheesy layer along the base of the casserole.
Step 2: Add the Chicken Mixture
In a mixing bowl, combine the cooked chicken and Alfredo sauce until well mixed. Spread the mixture evenly over the cheese layer.
Step 3: Add the Biscuit Topping
Cut each biscuit into four pieces and distribute them evenly over the chicken mixture. Sprinkle the remaining 1 cup of mozzarella cheese over the top.
Tip: Cutting the biscuits into smaller pieces allows them to cook evenly and develop a better balance of soft centers and lightly crisp edges.
Step 4: Bake Covered
Loosely cover the baking dish with aluminum foil, making sure the foil does not touch the cheese. Bake for 20 minutes.
Step 5: Finish Baking
Carefully remove the foil and continue baking for an additional 15 to 20 minutes, or until the biscuits are fully cooked and golden brown on top.
Doneness Check: The casserole is ready when the sauce is bubbling around the edges and the biscuit pieces are puffed, lightly browned, and cooked through.
Serve hot and enjoy this creamy, cheesy comfort-food favorite.
