It’s make-ahead friendly, customizable with proteins or veggies, and ideal for feeding a crowd. Whether for holidays, weekends, or weekday mornings, it’s a stress-free solution that doesn’t sacrifice taste.

Preparation Phase & Tools to Use

To make this Cheddar Bay Biscuit Egg Breakfast Casserole seamless, here are the essential tools and why they matter:

Mixing Bowls – You’ll need a few to mix the biscuit dough and whisk the eggs.
9×13-inch Baking Dish – Perfect size for even cooking and layered structure.
Whisk – Crucial for incorporating air into the eggs for a fluffy texture.
Oven – A preheated oven ensures the biscuits puff and the eggs set properly.
Silicone Spatula – Helps you spread ingredients evenly and scrape every cheesy bit.

Prepping in advance? Use a covered dish or aluminum foil to store the assembled casserole overnight. Just pop it into the oven the next morning and enjoy a fuss-free breakfast.

Ingredients for the Cheddar Bay Biscuit Egg Breakfast Casserole

Cheddar Bay Biscuit Mix – This is the flavor foundation, giving buttery, garlicky biscuit goodness in every bite.
Shredded Cheddar Cheese – Melts into the casserole for that gooey, savory finish.
Large Eggs – They create the custard base that binds everything together.
Milk or Half-and-Half – Adds creaminess and helps the eggs puff.
Garlic Powder – Boosts the signature Cheddar Bay flavor.
Chopped Parsley – For freshness and a pop of color on top.

Optional additions: cooked crumbled sausage, bacon bits, or sautéed veggies like spinach and bell peppers for a heartier casserole.

How To Make the Cheddar Bay Biscuit Egg Breakfast Casserole

Step 1: Prep the Oven and Pan

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with nonstick spray or butter.

Step 2: Mix the Biscuit Dough

Prepare the Cheddar Bay biscuit mix according to the package directions. Fold in shredded cheddar cheese for extra richness.

Step 3: Spread the Biscuit Base

Drop spoonfuls of biscuit dough evenly into the greased baking dish. Don’t worry about spreading them flat—they’ll rise beautifully as they bake.

Step 4: Whisk the Egg Mixture

In a mixing bowl, whisk together eggs, milk, garlic powder, and a pinch of salt and pepper until fully combined.

Step 5: Assemble the Casserole

Pour the egg mixture evenly over the biscuit dough. Sprinkle extra shredded cheese on top for added gooeyness.

Step 6: Bake to Perfection

Bake uncovered for 35–40 minutes or until the center is set and the top is golden. Let it rest for 5 minutes before slicing.

How to Serve and Store This Casserole

Serve warm slices topped with fresh parsley or a drizzle of hot sauce for extra kick. Pair it with a simple fruit salad or crispy bacon for a balanced breakfast.

To store, let the casserole cool completely. Cover and refrigerate for up to 4 days. Reheat individual portions in the microwave or oven. This dish also freezes well for up to 2 months—just thaw overnight in the fridge and reheat.
