Cheddar Bay Biscuit Casserole

Jump to Recipe

Cheddar Bay Biscuit Casserole combines fluffy biscuit topping, savory breakfast sausage, creamy eggs, and sharp cheddar cheese in one warm, hearty bake. It’s the kind of breakfast casserole that works just as well for slow weekend mornings as it does for holiday brunches, meal prep, or breakfast-for-dinner nights.

Using Red Lobster Cheddar Bay Biscuit Mix gives this casserole its buttery garlic flavor and golden biscuit topping without needing to make biscuits completely from scratch. The biscuit dough bakes right on top of the egg mixture, creating crisp golden peaks with soft, fluffy centers. A final drizzle of garlic herb butter over the top gives every bite that classic Cheddar Bay flavor.

This casserole comes together in about 15 minutes of prep time and bakes in under 35 minutes, making it easy enough for busy mornings while still feeling comforting and homemade.

Ingredients You’ll Need

Red Lobster Cheddar Bay Biscuit Mix

This recipe uses 1 cup of the biscuit mix along with the included herb seasoning packet. The mix creates soft biscuit topping with that familiar cheesy garlic flavor.

Ground Breakfast Sausage

Breakfast sausage gives the casserole a rich savory base. Make sure to brown and drain it well before adding it to the pie dish so the casserole doesn’t become greasy.

Eggs

Four large eggs create the creamy center of the casserole and help bind everything together.

Whole Milk or Heavy Cream

A small amount of milk or cream keeps the eggs soft and creamy while baking.

Sharp Cheddar Cheese

Sharp cheddar adds bold flavor and melts beautifully into both the eggs and biscuit topping.

Unsalted Butter

The melted butter mixes with the seasoning packet to create the buttery garlic topping brushed over the casserole near the end of baking.

How to Make Cheddar Bay Biscuit Casserole

1. Prepare the Pie Dish

Preheat your oven to 375°F and grease a 10-inch pie dish generously with butter or cooking spray.

Cook the sausage in a skillet over medium heat until fully browned, breaking it apart as it cooks. Drain the sausage well and spread it evenly across the bottom of the prepared dish.

2. Make the Egg Mixture

In a medium bowl, whisk together the eggs and milk until smooth.

Stir in:

• 1/2 cup shredded cheddar cheese
• 1/3 of the herb seasoning packet

Pour the egg mixture evenly over the sausage layer.

3. Mix the Biscuit Dough

In a separate bowl, combine:

• 1 cup biscuit mix
• 1/3 cup cold water
• 1/4 cup shredded cheddar cheese

Stir gently just until a soft dough forms. Avoid overmixing so the biscuit topping stays tender.

4. Add the Biscuit Topping

Drop rounded tablespoons of biscuit dough across the top of the casserole. Leave small gaps between the dough portions so steam can escape while baking.

Sprinkle the remaining cheddar cheese over the top.

5. Bake Until Golden

Bake the casserole for 22 minutes.

While it bakes, stir together:

• 4 tablespoons melted butter
• Remaining herb seasoning packet

After 22 minutes, drizzle the garlic herb butter over the biscuit topping. Return the casserole to the oven and bake for another 6–10 minutes until:

• The biscuits are deep golden brown
• The center is fully set
• A knife inserted into the middle comes out clean

Let the casserole rest for 5 minutes before slicing.

Tips for the Best Breakfast Casserole

Drain the Sausage Well

Removing excess grease helps keep the egg mixture creamy instead of oily.

Don’t Overmix the Biscuit Dough

Stir just until combined. Overmixing can make the biscuit topping dense instead of fluffy.

Leave Gaps Between the Dough

Spacing out the biscuit topping allows heat and steam to circulate evenly through the casserole.

Watch the Center Carefully

Pie dishes are deeper than sheet pans, so the middle may need a few extra minutes to fully cook.

Let It Rest Before Slicing

Allowing the casserole to sit for 5 minutes helps the eggs firm up for cleaner slices.

Easy Variations

This Cheddar Bay Biscuit Casserole is easy to adapt depending on the flavors you like best.

Add Vegetables

Try mixing in:

• Diced bell peppers
• Green onions
• Spinach
• Cooked mushrooms
• Jalapeños

Cook vegetables first so they don’t release too much moisture while baking.

Swap the Meat

Instead of breakfast sausage, try:

• Bacon
• Diced ham
• Turkey sausage
• Chorizo

Change the Cheese

Sharp cheddar works well, but you can also use:

• Pepper jack
• Monterey Jack
• Colby Jack
• Smoked gouda

Make It Spicy

Add hot sauce, crushed red pepper flakes, or diced jalapeños for extra heat.
