Ingredients for Chicken Alfredo Biscuit Casserole
This recipe works because each ingredient plays an important role in creating the perfect creamy, cheesy casserole texture.
1. Cooked Chicken – 2 Cups
The protein and heart of the dish.
Rotisserie chicken works beautifully for convenience.
Leftover roasted or grilled chicken also adds fantastic flavor.
Shredded chicken absorbs the Alfredo sauce better, while chopped pieces provide a heartier bite.
2. Jarred Alfredo Sauce – 2 Cups (15–16 oz)
This is what gives the casserole its signature creamy richness.
Alfredo sauce is typically made from cream, butter, and Parmesan, delivering a smooth, savory base.
Using jarred sauce keeps the recipe fast and beginner-friendly, but it still produces a restaurant-quality flavor.
3. Refrigerated Biscuit Dough – 1 Can (16.3 oz)
These biscuits transform into fluffy golden dumplings during baking.
Cutting them into quarters allows them to cook evenly while absorbing some of the sauce.
The tops become lightly crisp and buttery, while the bottoms stay soft and tender.
4. Shredded Mozzarella Cheese – 2 Cups (Divided)
The melty magic that binds everything together.
Mozzarella melts smoothly and creates a stretchy, cheesy topping.
Half goes on the bottom to create a rich cheese base, while the rest forms the golden bubbly topping.
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking.
2. Prepare the Creamy Chicken Filling
In a large mixing bowl:
Combine 2 cups cooked chicken with 2 cups Alfredo sauce.
Stir until every piece of chicken is fully coated in creamy sauce.
This mixture becomes the rich base of the casserole.
3. Create the Cheesy Base Layer
Spread 1 cup of shredded mozzarella cheese evenly across the bottom of the baking dish.
This step creates a melted cheese layer that blends into the Alfredo sauce while baking.
4. Add the Chicken Alfredo Mixture
Pour the chicken and sauce mixture into the dish and spread it evenly.
Make sure the chicken is distributed across the pan so each serving has plenty of flavor.
5. Prepare the Biscuit Topping
Open the can of refrigerated biscuits and cut each biscuit into four pieces.
Scatter the pieces evenly across the casserole.
Try to keep them mostly in a single layer so they bake evenly.
Some pieces will sink slightly into the sauce—this creates a soft dumpling-like texture underneath.
6. Add the Final Cheese Layer
Sprinkle the remaining 1 cup mozzarella cheese evenly over the biscuit pieces.
During baking, this will create a bubbly golden crust.
7. Bake the Casserole
Cover the dish loosely with foil.
Bake:
20 minutes covered
Then remove foil and bake 15–20 minutes uncovered
The casserole is ready when:
The biscuits are golden brown
The cheese is melted and lightly browned
The Alfredo sauce bubbles around the edges
If the center biscuits still appear doughy, bake an additional 5 minutes.
8. Rest Before Serving
Let the casserole sit for 5–10 minutes.
This allows the sauce to thicken slightly, making it easier to serve neat portions.

Pro Tips for the Best Alfredo Biscuit Casserole
Use Rotisserie Chicken for Maximum Flavor
Store-bought rotisserie chicken adds extra seasoning and tenderness without extra work.
Avoid Overcrowding the Biscuits
Keep biscuit pieces in a single layer whenever possible so they bake evenly and become golden on top.
Shred Your Own Cheese
Pre-shredded cheese contains anti-caking agents that prevent smooth melting.
Freshly shredded mozzarella creates a creamier melt.
Tent the Foil Loosely
Make sure the foil doesn’t touch the cheese during the first part of baking.
Check the Center Biscuit
Pull apart one center biscuit to ensure it’s fully cooked inside before serving.
