Ingredients You’ll Need

This recipe uses simple, easy-to-find ingredients to create a truly spectacular dish. Here’s what you’ll need to gather.

For the Creamy Chicken Filling

• Butter: The base of our rich and flavorful sauce.
• Onion & Garlic: Essential aromatics that build the first layer of flavor.
• All-Purpose Flour: This thickens the sauce, creating that perfect creamy consistency.
• Chicken Broth & Milk: The liquids for our homemade cream sauce. Whole milk will yield the richest result.
• Shredded Cooked Chicken: A store-bought rotisserie chicken or any leftover cooked chicken works perfectly. You’ll need about 3 cups.
• Frozen Peas and Carrots: For a classic, colorful, and nutritious addition. No need to thaw them first.
• Shredded Cheddar Cheese: Adds a wonderful sharp, savory flavor that melts beautifully into the sauce.
• Seasoning: Dried thyme, salt, and black pepper are all you need to perfectly season the filling.

For the Biscuit Topping

• Canned Biscuits: A 16.3-ounce can of refrigerated buttermilk biscuits makes this recipe incredibly simple.
• Melted Butter & Garlic Powder: Brushing the biscuits with garlic butter before baking makes them extra golden and delicious.

How to Make The Best Chicken Biscuit Casserole

Follow these simple steps to assemble and bake this comforting casserole. It’s a straightforward process that delivers a delicious result every time.

1. Preheat and Prep: Start by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish.
2. Sauté Aromatics: In a large skillet or Dutch oven, melt the butter over medium heat. Add the chopped onion and cook until softened, about 4-5 minutes. Stir in the minced garlic and cook for another minute until fragrant.
3. Make the Cream Sauce: Sprinkle the flour over the onions and stir continuously for one minute to cook out the raw flour taste. Gradually whisk in the chicken broth and milk until the mixture is smooth. Bring to a simmer and cook for 2-3 minutes, stirring, until the sauce has thickened.
4. Combine the Filling: Remove the skillet from the heat. Stir in the shredded chicken, frozen peas and carrots, shredded cheddar cheese, dried thyme, salt, and pepper. Mix until everything is well combined and coated in the creamy sauce.
5. Assemble the Casserole: Pour the chicken mixture into your prepared baking dish and spread it into an even layer.
6. Add the Biscuit Topping: Separate the canned biscuits and arrange them in a single layer on top of the chicken filling. In a small bowl, mix the melted butter with the garlic powder. Brush this mixture evenly over the tops of the biscuits.
7. Bake to Perfection: Bake for 25-30 minutes, or until the filling is hot and bubbly and the biscuits are deeply golden brown and cooked through. Let it rest for a few minutes before serving.

Tips for the Perfect Casserole

A few simple tricks can take your chicken biscuit casserole from great to absolutely unforgettable.

• Don’t Overcrowd the Biscuits: Leave a little space between the biscuits to allow them to expand and cook evenly.
• Use Freshly Grated Cheese: Pre-shredded cheese is often coated in anti-caking agents that prevent it from melting smoothly. Grating your own from a block makes a big difference.
• Check for Doneness: Ensure the biscuits are cooked through by inserting a toothpick into the center of one. It should come out clean.
• Let it Rest: Allowing the casserole to sit for 5-10 minutes after baking helps the sauce set up, making it easier to serve.

Delicious Variations to Try

One of the best things about this recipe is how easy it is to customize. Try one of these simple swaps to put your own spin on it.

• Add More Veggies: Corn, green beans, or mushrooms would all be delicious additions. For a delicious twist, try adding some sautéed leeks for a mild, sweet onion flavor.
• Change the Cheese: Swap the cheddar for a blend of Colby Jack, Monterey Jack, or even some Gruyère for a nuttier flavor.
• Spice it Up: Add a pinch of cayenne pepper or a dash of hot sauce to the filling for a little kick. For a different flavor profile, consider this Cajun Chicken Alfredo Orzo for inspiration.

What to Serve with Chicken Biscuit Casserole

This casserole is a hearty meal on its own, but it pairs wonderfully with a few simple sides. A crisp green salad with a simple vinaigrette is a perfect fresh contrast. For something a bit heartier, try serving it alongside some Garlic Parmesan Roasted Potatoes. Steamed green beans or roasted broccoli also make excellent and easy side dishes.

Storage and Reheating Instructions

Leftovers are one of the best parts! Store any leftover casserole tightly covered with foil or in an airtight container in the refrigerator for up to 3 days. To reheat, place individual portions in the microwave or reheat the entire casserole in a 350°F (175°C) oven until warmed through. The biscuits may soften slightly upon refrigeration but will still be delicious.
