How to Make Chicken Alfredo Biscuit Bake
Step 1: Preheat the Oven
Preheat your oven to 375°F.
Lightly coat a 9×13-inch baking dish with nonstick cooking spray.
Place the baking dish on a sheet pan if you’re concerned about the creamy filling bubbling over.
Step 2: Prepare the Chicken
Dice or shred approximately three cups of cooked chicken.
Rotisserie chicken, leftover roasted chicken, or cooked chicken breasts all work well.
Remove any skin or bones before adding the chicken to the casserole.
Step 3: Prepare the Broccoli
Cut the broccoli into small florets.
Large pieces may remain too firm during baking, so keep them small and evenly sized.
For softer broccoli, steam or microwave it for approximately two minutes before adding it to the filling.
Step 4: Melt the Butter
Place two tablespoons of butter in a large skillet over medium heat.
Allow the butter to melt completely.
Step 5: Cook the Onion
Add the diced onion to the skillet.
Cook for approximately 3–4 minutes, stirring occasionally, until it becomes soft and translucent.
Avoid browning the onion too deeply.
Step 6: Add the Garlic
Add the minced garlic.
Cook for approximately 30 seconds, stirring constantly.
Garlic burns quickly, so add the remaining ingredients as soon as it becomes fragrant.
Step 7: Add the Broccoli
Add the broccoli florets to the skillet.
Cook for approximately 2–3 minutes.
The broccoli doesn’t need to become completely tender because it will continue cooking in the oven.
Step 8: Prepare the Alfredo Sauce
Reduce the heat to low.
Add the Alfredo sauce, softened cream cheese, and milk.
Stir gently until the cream cheese melts and the sauce becomes smooth.
If the mixture appears extremely thick, add another small splash of milk.
Step 9: Season the Filling
Add the Italian seasoning, garlic powder, onion powder, salt, and black pepper.
Stir until the seasonings are evenly distributed.
Taste the sauce before adding additional salt because Alfredo sauce and Parmesan can already be salty.
Step 10: Add the Parmesan
Stir the grated Parmesan cheese into the sauce.
Continue cooking over low heat until it begins to melt.
Do not allow the sauce to boil because excessive heat can cause it to separate.
Step 11: Add the Chicken
Fold the cooked chicken into the Alfredo sauce.
Stir until every piece is evenly coated.
Cook for approximately two minutes, just until the chicken is warmed.
Step 12: Add the Mozzarella
Stir ½ cup of shredded mozzarella into the filling.
Reserve the remaining cheese for layering beneath the biscuits.
Step 13: Fill the Baking Dish
Transfer the chicken Alfredo mixture to the prepared baking dish.
Spread it into an even layer, making sure the chicken and broccoli are distributed throughout the casserole.
Step 14: Add the Cheese Layer
Sprinkle the remaining cup of mozzarella evenly over the Alfredo filling.
This creates a cheesy layer between the creamy chicken and the biscuit topping.
Step 15: Prepare the Biscuits
Open the refrigerated biscuit dough and separate the biscuits.
You can leave them whole or cut each biscuit into two or four pieces.
Smaller pieces cook more evenly and make the casserole easier to serve.
Step 16: Arrange the Biscuits
Arrange the biscuit pieces evenly over the cheese.
Leave a little space between them so the hot filling can circulate and help the dough cook properly.
Avoid pushing the biscuits deeply into the sauce.
Step 17: Prepare the Garlic Butter
Combine the melted butter, garlic powder, Italian seasoning, and Parmesan cheese in a small bowl.
Stir until well mixed.
Step 18: Brush the Biscuits
Brush the garlic butter generously over the tops of the biscuits.
This adds flavor and helps the biscuits develop a golden, savory crust.
Step 19: Bake
Place the casserole in the preheated oven.
Bake uncovered for approximately 25–30 minutes, or until the filling is bubbling and the biscuits are golden brown.
Step 20: Check the Biscuits
Gently lift one biscuit near the center of the casserole.
Make sure the bottom is cooked and no raw dough remains.
If necessary, loosely cover the top with foil and continue baking for another 5–10 minutes.
The foil prevents excessive browning while the bottom of the biscuits finishes cooking.
Step 21: Rest
Remove the casserole from the oven.
Allow it to rest for approximately 10 minutes.
Resting gives the Alfredo sauce time to thicken and prevents the filling from running when served.
Step 22: Garnish and Serve
Sprinkle the casserole with chopped parsley, additional Parmesan, or crushed red pepper flakes.
Serve warm, making sure each portion contains creamy chicken filling, vegetables, melted cheese, and a golden biscuit.
The Best Chicken to Use
Cooked chicken makes this recipe quick and convenient.
Good choices include:
- Rotisserie chicken
- Baked chicken breasts
- Grilled chicken
- Poached chicken
- Leftover roasted chicken
- Cooked chicken thighs
- Canned chicken, well drained
Chicken thighs create a richer filling, while chicken breasts provide a lighter flavor.
If using canned chicken, drain it thoroughly and break it into large pieces before adding it to the sauce.
Can I Use Raw Chicken?
It’s better to cook the chicken first.
The casserole may not bake long enough for large pieces of raw chicken to cook safely without overbrowning the biscuits.
If starting with raw chicken, dice it into small pieces and sauté it in the skillet until it reaches an internal temperature of 165°F.
Remove it from the skillet, prepare the sauce, and return the chicken before assembling the casserole.
The Best Alfredo Sauce
A thick, creamy Alfredo sauce works best because vegetables and chicken may release some moisture during baking.
You can use:
- Jarred Alfredo sauce
- Roasted garlic Alfredo
- Four-cheese Alfredo
- Homemade Alfredo sauce
- Light Alfredo sauce
- Bacon Alfredo sauce
If your sauce is very thin, reduce the milk or simmer it briefly before assembling the casserole.
Homemade Alfredo Sauce
To prepare homemade Alfredo sauce, melt four tablespoons of butter in a saucepan.
Add three minced garlic cloves and cook for approximately 30 seconds.
Slowly stir in two cups of heavy cream.
Simmer gently for approximately three minutes, then add:
- 1½ cups freshly grated Parmesan
- ½ teaspoon Italian seasoning
- ¼ teaspoon black pepper
- Salt to taste
Stir over low heat until smooth.
Use approximately three cups of homemade sauce in place of the jarred Alfredo sauce, cream cheese, and milk.
The Best Biscuits for the Topping
Refrigerated buttermilk or homestyle biscuits are easy to use and bake into a fluffy topping.
You can also use:
- Flaky-layer biscuits
- Southern-style biscuits
- Homemade biscuit dough
- Cheddar biscuits
- Garlic biscuits
- Frozen biscuits, partially thawed
Avoid using oversized biscuits unless you cut them into smaller pieces. Thick biscuits can brown on top before cooking completely underneath.
How to Prevent Raw Biscuit Dough
Raw dough can occur when the biscuits are packed too closely together or pushed into the sauce.
For evenly cooked biscuits:
- Cut large biscuits into smaller pieces
- Leave space between the pieces
- Keep the biscuits on top of the filling
- Use hot or warm Alfredo filling
- Bake the casserole uncovered
- Cover with foil only after the tops are golden
- Check a center biscuit before removing the casserole
A metal baking dish may also cook the bottom of the biscuits more quickly than a thick ceramic dish.
Can I Use Crescent Roll Dough?
Yes.
Unroll the crescent dough and cut it into small pieces.
Arrange the pieces loosely over the chicken Alfredo filling and brush them with garlic butter.
Crescent dough creates a lighter, flakier topping and may bake more quickly than biscuits.
Begin checking the casserole after approximately 20 minutes.
Can I Use Puff Pastry?
Yes.
Allow the filling to cool slightly before covering it with thawed puff pastry.
Cut a few small openings in the pastry so steam can escape.
Brush the top with beaten egg and bake until deeply golden and puffed.
Puff pastry creates an elegant crust similar to a creamy chicken pot pie.
Chicken Alfredo Biscuit Bake with Bacon
Cook and crumble approximately 6–8 slices of bacon.
Stir half the bacon into the Alfredo filling and reserve the rest for the top.
Sprinkle the finished casserole with bacon, green onions, and additional Parmesan cheese.
Chicken Broccoli Alfredo Biscuit Bake
Increase the broccoli to three cups.
Steam it briefly before adding it to the sauce if you prefer very tender vegetables.
You can also replace part of the broccoli with cauliflower florets.
Spinach Chicken Alfredo Biscuit Bake
Add approximately two cups of fresh spinach to the sauce.
Stir it into the skillet after the garlic and cook until wilted.
If using frozen spinach, thaw it and squeeze out as much liquid as possible before adding it.
Mushroom Chicken Alfredo Biscuit Bake
Slice eight ounces of mushrooms.
Cook them with the onion until their moisture evaporates and they begin to brown.
Mushrooms add a savory flavor that pairs especially well with garlic, Parmesan, and chicken.
Spicy Chicken Alfredo Biscuit Bake
Add ½ teaspoon of crushed red pepper flakes to the Alfredo filling.
You can also add diced jalapeños or replace some of the mozzarella with Pepper Jack cheese.
Finish the casserole with hot sauce for additional heat.
Sun-Dried Tomato Alfredo Biscuit Bake
Add ½ cup of drained and chopped sun-dried tomatoes to the filling.
Their slightly sweet, tangy flavor balances the rich Alfredo sauce.
Spinach makes an excellent addition to this variation.
Buffalo Chicken Alfredo Biscuit Bake
Stir ⅓ cup of buffalo sauce into the Alfredo filling.
Replace half of the mozzarella with Monterey Jack cheese.
Finish the casserole with green onions and a drizzle of ranch or blue cheese dressing.
Can I Add Pasta?
Yes.
Add approximately 2 cups of cooked pasta to the chicken Alfredo mixture.
Good options include:
- Penne
- Rotini
- Bow-tie pasta
- Small shells
- Rigatoni
If adding pasta, increase the Alfredo sauce by approximately one cup so the casserole remains creamy.
Can I Add More Vegetables?
Yes.
Good additions include:
- Peas
- Spinach
- Mushrooms
- Cauliflower
- Bell peppers
- Asparagus
- Green beans
- Corn
- Diced carrots
Cook firm or watery vegetables before adding them.
Drain vegetables thoroughly so they don’t dilute the Alfredo sauce.
What to Serve with Chicken Alfredo Biscuit Bake
This casserole is filling enough to serve on its own, but it also pairs well with:
- Green salad
- Caesar salad
- Roasted vegetables
- Steamed green beans
- Garlic-roasted broccoli
- Tomato cucumber salad
- Sautéed spinach
- Fresh fruit
- Marinated tomatoes
A crisp salad or lightly seasoned vegetable side balances the creamy sauce, cheese, and buttery biscuits.
Can I Prepare It Ahead?
Yes.
Prepare the Chicken Alfredo filling and spread it in the baking dish.
Cover and refrigerate for up to 24 hours.
When ready to bake, warm the filling slightly or allow the dish to sit at room temperature for approximately 20 minutes.
Add the mozzarella, biscuits, and garlic butter immediately before baking.
Do not refrigerate the casserole with the raw biscuits already on top because they can absorb moisture from the sauce.
Storage
Allow the casserole to cool before covering the baking dish or transferring leftovers to an airtight container.
Refrigerate for up to 3–4 days.
The biscuits will soften as they absorb moisture from the filling, but they will still taste delicious when reheated.
How to Reheat Chicken Alfredo Biscuit Bake
Reheat the casserole in a 350°F oven until hot.
Cover it loosely with foil to prevent the biscuits from becoming too dark, then uncover it during the final few minutes.
Individual portions can be reheated in the microwave.
Add a spoonful of milk or Alfredo sauce if the filling has become very thick.
Can You Freeze Chicken Alfredo Biscuit Bake?
The chicken Alfredo filling can be frozen before adding the biscuits.
Cool the filling completely and store it in a freezer-safe container for up to 3 months.
Thaw overnight in the refrigerator.
Transfer the filling to a baking dish, warm it slightly, and add fresh biscuit dough before baking.
Freezing the fully assembled casserole may change the texture of the biscuits and creamy sauce.

Pro Tips
Use cooked chicken and warm Alfredo filling so the casserole heats evenly without overbaking the biscuits.
Cut large biscuits into halves or quarters and leave space between them. This allows the hot air to circulate and helps the bottoms cook completely.
Keep the filling thick, drain vegetables carefully, and cover the casserole with foil only if the biscuit tops become golden before the centers are cooked.
Finish with garlic butter, Parmesan, and parsley for the perfect combination of creamy Alfredo chicken, melted cheese, tender vegetables, and fluffy golden biscuits.
