4-Ingredient Chicken Alfredo Biscuit Casserole

How to Make Chicken Alfredo Biscuit Casserole

Step 1: Prep the Oven

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.

Step 2: Prepare the Filling

In a mixing bowl, combine:

shredded chicken
Alfredo sauce

Stir until the chicken is evenly coated.

Spread the mixture evenly into the prepared baking dish.

Step 3: Add the Biscuits

Separate the biscuits and place them evenly over the chicken mixture in a single layer.

They’ll puff up beautifully as they bake.

Step 4: Add Cheese

Sprinkle Parmesan cheese evenly over the biscuits for a savory, golden topping.

Step 5: Bake

Bake for 22–28 minutes until:

biscuits are golden brown
filling is hot and bubbly

Step 6: Rest Before Serving

Let the casserole rest for 5–10 minutes. This helps the sauce thicken slightly.

Then scoop generous servings and enjoy!

Tips for the Best Casserole

Use Good Alfredo Sauce

Look for a sauce made with real cream, butter, and Parmesan for the best flavor.

Keep Biscuits Cold

Cold biscuits puff up higher in the oven.

Don’t Overbake

Remove the casserole once biscuits are golden so they stay soft and fluffy.

Let It Rest

Allowing the casserole to rest helps the filling thicken.
