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.

This 4-Ingredient Chicken Alfredo Biscuit Casserole is the ultimate weeknight “cheat code” for a comforting Italian-style dinner. By combining the rich, garlic-cream flavor of Alfredo sauce with pillowy biscuit quarters, you create a dish that is half-pasta-bake and half-chicken-and-dumplings. The mozzarella base acts as a “cheese floor,” ensuring that every scoop has a stretchy, gooey pull from top to bottom.

How To Make 4-Ingredient Chicken Alfredo Biscuit Casserole:

Step 1: Prep the Oven and Pan: Preheat your oven to 375°F. Lightly grease a 9×13-inch glass baking dish with cooking spray or butter.

Tip: Glass is the best choice here because it allows you to see if the Alfredo sauce is bubbling at the bottom, which is your best indicator that the chicken is heated through and the flavors have melded.

Step 2: Create the Creamy Base: In a large bowl, stir together your cooked chicken and the Alfredo sauce until the meat is fully coated. Sprinkle 1 cup of the mozzarella evenly over the bottom of your prepared baking dish, then pour the chicken mixture over the cheese.

Step 3: The “Biscuit Bubble” Layer: Quarter each of the 8 biscuits using a knife or kitchen shears. Scatter the pieces over the chicken mixture in a single layer.

Tip: Don’t be afraid to nestle a few pieces slightly into the sauce! This creates a “dumpling” texture on the bottom of the biscuit while the top stays crisp and golden.

Step 4: Cheese and First Bake: Top the biscuits with the remaining 1 cup of mozzarella. Cover the dish loosely with a “tented” piece of foil (so the cheese doesn’t stick) and bake for 20 minutes.

Step 5: The Golden Finish: Remove the foil and bake for another 15/20 minutes. You are looking for the biscuits to be deep golden brown and the sauce to be bubbling vigorously around the edges.

Step 6: The Rest: Let the casserole sit for 5/10 minutes. This rest period is crucial—it allows the Alfredo sauce to thicken up so it doesn’t run all over the plate when you serve it.
