My mother-in-law made this last Sunday, and I couldn’t believe how creamy and comforting it was. It’s a total game changer made with just four ingredients.

This 4-Ingredient Chicken Alfredo Biscuit Casserole is the ultimate weeknight “cheat code” for a cozy, Italian-style dinner. By combining the rich, garlicky creaminess of Alfredo sauce with soft biscuit pieces, you get a dish that feels like a mix between a pasta bake and chicken-and-dumplings. The mozzarella on the bottom creates a cheesy base, so every scoop is gooey and stretchy from top to bottom.
4-Ingredient Chicken Alfredo Biscuit Casserole
Ingredients:
- 1 (16.3 oz) can refrigerated biscuit dough
- 2 cups Alfredo sauce (1 jar)
- 2 cups cooked chicken, shredded or chopped
- 2 cups shredded mozzarella cheese, divided
How to Make 4-Ingredient Chicken Alfredo Biscuit Casserole
Step 1: Prepare the oven and dish
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter.
Tip: A glass baking dish works well because you can easily see when the sauce starts bubbling at the bottom.
Step 2: Make the creamy chicken mixture
In a large bowl, combine the cooked chicken and Alfredo sauce until the chicken is fully coated. Sprinkle 1 cup of mozzarella evenly over the bottom of the baking dish, then spread the chicken mixture on top.
Step 3: Add the biscuit layer
Cut each biscuit into four pieces using a knife or kitchen scissors. Scatter the pieces evenly over the chicken mixture.
Tip: Press a few biscuit pieces slightly into the sauce so the bottoms turn soft and dumpling-like while the tops bake golden and crisp.
Step 4: Add cheese and first bake
Sprinkle the remaining 1 cup mozzarella over the biscuits. Cover the dish loosely with foil (tent it slightly so it doesn’t stick to the cheese) and bake for 20 minutes.
Step 5: Finish baking
Remove the foil and bake for another 15–20 minutes, until the biscuits are golden brown and the sauce is bubbling around the edges.
Step 6: Let it rest
Allow the casserole to sit for 5–10 minutes before serving. This helps the Alfredo sauce thicken so it stays creamy when scooped. 🍽️
