Simple, Flavor-Packed Ingredients for a Delicious Start to Your Day

Here’s everything you need to make this cheesy, eggy, biscuit-filled casserole.

Ingredients:

• 1 box Cheddar Bay Biscuit Mix (usually includes dry mix + seasoning packet)
• 1/2 cup cold water
• 1/2 cup shredded cheddar cheese (extra sharp recommended)
• 6 large eggs
• 1/2 cup milk (or any milk alternative)
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/2 teaspoon black pepper
• 1/4 teaspoon paprika (optional)
• 1/2 cup cooked crumbled chicken sausage or chopped rotisserie chicken (optional)
• 2 tablespoons chopped green onions or fresh parsley for garnish

This combination delivers rich flavor and satisfying texture in every bite. You can also make it your own with easy ingredient swaps.

Everything You Need for a Hassle-Free Bake

You’ll need just a few kitchen tools to bring this dish to life.

Kitchen Equipment:

• Large mixing bowl
• Whisk
• Measuring cups and spoons
• 9×13-inch baking dish
• Oven mitts
• Rubber spatula or wooden spoon
• Non-stick spray or butter for greasing

No need for fancy equipment—just prep, mix, pour, and bake.

How to Make Cheddar Bay Biscuit Breakfast Casserole Perfectly

Step 1: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with non-stick spray or butter.

Step 2: Prepare the Cheddar Bay biscuit mix according to the package instructions. Typically, you’ll mix the dry biscuit mix with water and shredded cheese until combined.

Step 3: Drop spoonfuls of the biscuit dough evenly across the bottom of the baking dish. Spread gently but don’t flatten completely. The dough will expand as it bakes.

Step 4: In a separate bowl, whisk together eggs, milk, garlic powder, onion powder, pepper, and paprika.

Step 5: Pour the egg mixture evenly over the biscuit dough. If using cooked chicken sausage or shredded chicken, sprinkle it over the top.

Step 6: Bake uncovered for 30 to 35 minutes, or until the eggs are set and the top is golden. You can check doneness by inserting a knife into the center—it should come out clean.

Step 7: Let rest for 5 minutes. Garnish with chopped green onions or parsley before serving.

The result is a fluffy, flavorful breakfast recipes casserole that brings together everything you love about brunch in one bite.
