- Frozen Cheddar Bay Biscuits: These biscuits bring a deliciously soft texture and cheesy note that give the casserole its unique charm.

How to Make Cheddar Bay Biscuit Breakfast Casserole Recipe
Step 1: Prepare the Baking Dish and Biscuits
Start by preheating your oven to 350ºF and lightly spray a 9×13-inch baking dish with cooking spray to prevent sticking. Next, take your frozen Cheddar Bay Biscuits, bake them according to the package directions, then chop each biscuit into 6 to 8 bite-sized pieces before spreading them evenly across the bottom of the prepared dish. This layer forms the hearty base that will soak up all the delicious flavors.
Step 2: Cook the Sausage
Heat a skillet over medium-high heat and cook the sausage until it is thoroughly browned with no pink remaining. Make sure to crumble it into small pieces for even cooking and distribution throughout the casserole. Once cooked, drain the fat to avoid an overly greasy dish, then sprinkle the sausage evenly over the biscuit pieces.
Step 3: Add Cheese
Generously top the sausage with 1½ cups of shredded cheddar cheese. Don’t be shy here—this cheesy layer is what makes the casserole absolutely irresistible, adding pockets of creamy texture and savory richness.
Step 4: Mix and Pour the Egg Mixture
In a mixing bowl, whisk together 8 large eggs, 2 cups of milk, and a pinch of salt and pepper to taste. Once combined, pour this custardy mixture evenly over the biscuit, sausage, and cheese layers, making sure the eggs seep into every nook and cranny. This step is crucial to bind the casserole and give it that beautifully soft, golden finish after baking.
Step 5: Bake to Perfection
Bake your casserole uncovered in the preheated oven for about 1 hour, or until the eggs are fully set and the top is slightly golden. The smell filling your kitchen will be heavenly as the biscuits absorb the savory flavors and the cheese melts into gooey perfection.

Garnishes
Fresh herbs like chopped parsley or chives make fantastic garnishes, adding a pop of green and a fresh bite to contrast the richness. A dollop of sour cream or a drizzle of hot sauce can take this breakfast casserole to the next level of flavor complexity.
Side Dishes
For a balanced breakfast, serve it alongside fresh fruit or a crisp green salad. If you want to keep the comfort-food vibe, crispy breakfast potatoes or roasted veggies add complementary textures and flavors.
Creative Ways to Present
Try serving your Cheddar Bay Biscuit Breakfast Casserole Recipe in individual ramekins for a charming personal touch, or layer it with sautéed spinach and mushrooms for an extra nutritional boost and flavor twists. It even works beautifully as a brunch buffet centerpiece because it can be made ahead and reheated with ease.
Make Ahead and Storage
Storing Leftovers
After enjoying your breakfast casserole, store any leftovers in an airtight container in the refrigerator. It will keep well for up to 3 days, making it a perfect make-ahead meal that tastes just as delightful when reheated.
Freezing
If you want to prepare this Cheddar Bay Biscuit Breakfast Casserole Recipe in advance, assemble and bake it but hold off on slicing it before freezing. Wrap tightly with foil and plastic wrap, then freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
To reheat, simply warm in a 350ºF oven until heated through, about 20 to 30 minutes, to keep the casserole’s texture intact and the flavors fresh. Microwaving works too for a quicker fix, but the oven method preserves the nice crust on top best.
FAQs
Can I use fresh biscuits instead of frozen Cheddar Bay Biscuits?
Absolutely! While this recipe shines with the unique flavor of the frozen biscuits, fresh or homemade cheddar biscuits can be a great substitute that adds a personal touch.
Is it possible to make this casserole vegetarian?

Can I prepare this casserole the night before?
Definitely. You can assemble it the night before, cover, and refrigerate so it’s ready to bake first thing in the morning.
What kind of sausage works best for this recipe?
Pork breakfast sausage is traditional and flavorful, but you can use turkey or chicken sausage for a leaner option without sacrificing taste.
How can I make this dish more spicy?
Add diced jalapeños to the sausage layer or sprinkle red pepper flakes into the egg mixture for a nice kick of heat.
