Pro Tips

Master the Biscuit Texture
The key to perfect Cheddar Bay Biscuit topping lies in how you handle the dough. Keep your butter and buttermilk extremely cold before mixing. When incorporating the butter into the flour mixture, aim for pea-sized pieces rather than a homogeneous mixture. These small butter pockets create steam during baking, resulting in those delightful flaky layers that make the biscuits irresistible. Work quickly and with minimal handling to prevent the butter from melting before baking.

Create Flavor Depth
For maximum flavor impact, sauté your breakfast sausage and vegetables before adding them to the egg mixture. This simple extra step caramelizes their natural sugars and releases aromatics that infuse throughout the entire breakfast casserole. For the cheese, use freshly grated sharp cheddar rather than pre-shredded varieties, which often contain anti-caking agents that can affect melting quality and flavor.

Perfect Timing Techniques
The most common pitfall with this Cheddar Bay Biscuit Egg Breakfast Casserole is overbaking, which can lead to rubbery eggs. Remove the casserole from the oven when the biscuit topping is golden brown and the center is just set but still has a slight jiggle. The residual heat will continue cooking the eggs to perfection as it rests. Allow the casserole to rest for 10-15 minutes before serving to let the flavors meld and the texture stabilize.

Instructions

Step 1: Prepare the Egg Base
Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish. In a large bowl, whisk together the eggs, milk, and heavy cream until well combined and slightly frothy. This aeration will help create a lighter texture in your Cheddar Bay Biscuit Egg Breakfast Casserole. Season with salt, pepper, and cayenne if using. Stir in 1½ cups of shredded cheddar (reserving the remaining ½ cup for topping), the cooked breakfast sausage, diced bell pepper, and most of the green onions, saving some for garnish.

Step 2: Craft the Biscuit Topping
In a medium bowl, whisk together the flour, baking powder, garlic powder, salt, and Old Bay seasoning. Using a pastry cutter or two forks, cut the cold butter into the flour mixture until it resembles coarse crumbs with some pea-sized pieces remaining. Stir in the shredded cheddar cheese. Make a well in the center and pour in the cold buttermilk. Stir just until the mixture comes together – it should look shaggy and not entirely smooth.

Step 3: Assemble and Bake
Pour the egg mixture into your prepared baking dish, spreading it evenly. Drop spoonfuls of the biscuit dough evenly across the top of the egg mixture. You’re looking for a rustic appearance rather than a smooth covering. Sprinkle the remaining ½ cup of cheddar over the biscuit dollops. Bake for 35-40 minutes, until the biscuit topping is golden brown and the egg mixture is just set in the center.

Step 4: Add the Signature Finish
While the breakfast casserole bakes, prepare the garlic butter topping by mixing the melted butter with garlic powder, dried parsley, and a pinch of salt. As soon as the casserole comes out of the oven, brush this mixture over the hot biscuit topping. This step is essential for achieving that authentic Cheddar Bay Biscuit flavor that makes this Cheddar Bay Biscuit Egg Breakfast Casserole so special.

Step 5: Rest and Serve
Allow the casserole to rest for 10-15 minutes before serving. This resting period lets the eggs set fully and makes serving cleaner and easier. Sprinkle with the reserved green onions just before serving for a fresh pop of color and flavor. Cut into generous squares and watch your family’s faces light up as they dig into this comforting breakfast masterpiece.

Variations

Vegetarian Delight
Transform this Cheddar Bay Biscuit Egg Breakfast Casserole into a vegetarian feast by replacing the sausage with sautéed mushrooms and spinach. The earthy mushrooms provide a meaty texture while the spinach adds nutritional value and beautiful color contrast. For added flavor depth, include some caramelized onions and roasted garlic. This variation works wonderfully with the addition of feta or goat cheese for a tangy counterpoint to the rich biscuit topping.

Seafood Sensation
Honor the maritime inspiration of the original Cheddar Bay Biscuits by incorporating seafood into your breakfast casserole. Fold in 1 cup of cooked crab meat or small cooked shrimp along with a few tablespoons of minced fresh herbs like dill and chives. Increase the Old Bay seasoning in both the egg mixture and biscuit topping for an authentic coastal flavor. This elevated version makes an impressive brunch centerpiece for special occasions.

Southwestern Kick
Give your Cheddar Bay Biscuit Egg Breakfast Casserole a Tex-Mex twist by adding a diced jalapeño, substituting pepper jack for some of the cheddar, and mixing in ½ cup of black beans and ¼ cup of corn kernels. Season the egg mixture with cumin, chili powder, and oregano. Serve with avocado slices, salsa, and a dollop of sour cream for a breakfast fiesta that will energize your morning.

Storage and Serving

This Cheddar Bay Biscuit Egg Breakfast Casserole can be refrigerated in an airtight container for up to 3 days. For best results when reheating, cover with foil and warm in a 325°F (165°C) oven for about 15 minutes, or until heated through. The microwave works for individual portions, but the biscuit topping won’t retain its crispness as well.

For make-ahead convenience, you can prepare the egg mixture and store it separately from the dry biscuit ingredients the night before. In the morning, quickly mix the wet ingredients into the biscuit mixture, assemble, and bake. This approach gives you fresh-baked quality with minimal morning effort.

Serve your breakfast casserole with a simple fruit salad for a balanced meal. For an extra-special brunch, pair it with a light arugula salad dressed with lemon vinaigrette to cut through the richness. A pitcher of Bloody Marys or mimosas completes the spread for weekend entertaining. For family breakfasts, simply add a bowl of fresh berries and your favorite morning beverage.

FAQs

Can I make this casserole the night before?
Yes! You can fully assemble the Cheddar Bay Biscuit Egg Breakfast Casserole (without baking), cover it tightly, and refrigerate overnight. Add about 5-10 minutes to the baking time when cooking from cold. Alternatively, prepare the egg mixture and store it separately from the dry biscuit ingredients, then quickly assemble in the morning.

Can I use biscuit mix instead of making the biscuits from scratch?
Absolutely. While homemade delivers the best flavor, you can use 2 cups of biscuit mix combined with ¼ teaspoon of Old Bay seasoning, 1 teaspoon of garlic powder, and 1 cup of shredded cheddar. Mix with ¾ cup of milk and proceed with the recipe.

Why is my egg mixture watery?
This typically happens when the vegetables release excess moisture. Sauté vegetables before adding them to remove some moisture, and make sure your cheese is freshly grated, as pre-shredded cheese contains anti-caking agents that can affect texture.

Can I freeze leftovers?
Yes, this breakfast casserole freezes well. Cut into individual portions, wrap tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

What can I substitute for Old Bay seasoning?
If you don’t have Old Bay, make your own by combining paprika, black pepper, salt, and a pinch of cayenne, celery salt, and ground nutmeg. Alternatively, Cajun seasoning makes a good substitute but may be spicier.

Conclusion

This Cheddar Bay Biscuit Egg Breakfast Casserole is comfort food at its finest — a harmonious marriage of buttery, garlicky biscuits and a savory, protein-rich egg base that satisfies all your breakfast cravings in one dish. It’s the kind of recipe that creates traditions, whether for holiday mornings, weekend family brunches, or treating overnight guests to something special.
