Perfect for busy weeknights, family gatherings, or meal prep, this casserole is one of those dishes that everyone goes back for — and there are rarely leftovers.

Why This Chicken Alfredo Biscuit Casserole Works So Well

The secret to this recipe is layering simple ingredients in a way that builds flavor and texture:

• The Alfredo sauce creates a rich, creamy base
• The chicken adds protein and heartiness
• The cheese melts into a smooth, gooey layer
• The biscuits bake into a fluffy, golden topping

As everything cooks together, the sauce thickens, the cheese bubbles, and the biscuits absorb just enough moisture to stay soft inside while crisping up on top.

Ingredients (Serves 6–8)

• 2 cups cooked chicken, shredded or diced
• 1 jar (15 oz) Alfredo sauce
• 1 cup shredded mozzarella cheese
• ½ cup grated Parmesan cheese
• 1 can refrigerated biscuit dough
• 1 cup broccoli (fresh or frozen, optional)
• ½ teaspoon garlic powder
• ½ teaspoon black pepper

Equipment Needed

• 9×13-inch baking dish
• Large mixing bowl
• Knife and cutting board
• Spoon or spatula

Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C). Lightly grease a baking dish to prevent sticking.

Step 2: Make the Creamy Chicken Filling

In a large mixing bowl, combine:

• Cooked chicken
• Alfredo sauce
• Garlic powder
• Black pepper
• Broccoli (if using)

Mix until everything is evenly coated in the creamy sauce.

Step 3: Add Cheese to the Filling

Stir in:

• Half of the mozzarella cheese
• Half of the Parmesan cheese

This creates a rich, cheesy base that melts beautifully while baking.

Step 4: Assemble the Casserole Base

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

Make sure the sauce covers the bottom fully to keep everything moist during baking.

Step 5: Prepare the Biscuit Topping

Cut each biscuit into 4 pieces.

Scatter the pieces evenly over the top of the casserole.

They should slightly overlap but still allow steam to escape.

Step 6: Add Final Cheese Layer

Sprinkle the remaining mozzarella and Parmesan cheese over the biscuit pieces.

This creates a golden, bubbly crust.

Step 7: Bake to Perfection

Bake for 25–30 minutes, until:

• Biscuits are golden brown
• Cheese is melted and bubbling
• Filling is hot and creamy

If biscuits brown too quickly, cover loosely with foil and continue baking.

Step 8: Rest and Serve

Let the casserole rest for 5 minutes before serving.

This helps the sauce thicken and makes scooping easier.

Pro Tips for the Best Results

• Use rotisserie chicken for extra flavor and convenience
• Cut biscuits evenly for consistent baking
