What You’ll Need for This Breakfast Casserole
- Grands! Biscuits – These flaky, buttery layers form the hearty crust that holds everything together and adds rich texture to every bite.
- Precooked sausage crumbles – Savory and spiced just right, sausage adds meaty depth and classic breakfast flavor.
- Shredded mozzarella – Brings a creamy, melty layer that binds beautifully with the eggs and sausage.
- Shredded cheddar cheese – Adds sharpness and a golden top, boosting both flavor and visual appeal.
- Eggs – The heart of the casserole, eggs bind everything together while delivering protein and that signature custardy bite.
- Milk – Lightens the eggs into a smooth, pourable custard and helps bake the dish evenly.
- Salt and pepper – Simple, essential seasoning that ties all the flavors together.
Quick & Cozy: How to Make Breakfast Casserole
Start by preheating your oven and preparing your baking dish with nonstick spray. Press biscuit dough evenly into the bottom to form a crust.
Sprinkle on the sausage crumbles and cheeses, layering them generously over the biscuit base. In a separate bowl, whisk together the eggs, milk, salt, and pepper.
Pour the egg mixture evenly over the casserole, then slide it into the oven. Bake until the center is set and the top is golden. Let it rest briefly, then slice and serve warm.
Flavor Boosts & Smart Tips for Success
To deepen the flavor and add texture, consider sautéing onions, peppers, or mushrooms and mixing them into the sausage layer. The key is cooking vegetables beforehand to avoid excess moisture.
For an even flakier crust, you can use homemade biscuit dough—just par-bake it first to ensure it cooks through under the egg layer.
Make this casserole ahead by assembling it the night before. Simply cover and refrigerate, then bake fresh in the morning with a few extra minutes of cook time. It’s a time-saver for holiday breakfasts or weekend guests.
Storing and Reheating Breakfast Casserole Like a Pro
Store leftovers in an airtight container in the refrigerator for up to 4 days. Individual portions can also be wrapped and frozen for up to 2 months.
To reheat, microwave slices for 1–2 minutes, or warm in a 325°F oven until heated through. For best results, thaw frozen portions overnight in the fridge before reheating.
Breakfast Biscuit Casserole Recipe
Ingredients
- 1 cup shredded cheddar cheese
- 1 16.3-ounce can Grands! Biscuits (8 count)
- Salt and black pepper to taste
- 1 cup shredded mozzarella cheese
- 1 8-ounce package precooked sausage crumbles (or 1 cup of cooked crumbled sausage)
- 8 large eggs beaten
- 1 cup milk at room temperature
Instructions
- Preheat the oven to 425°F. Generously grease a 9×13-inch baking dish and arrange the biscuit dough across the bottom, pressing the edges together to form a uniform crust. Evenly scatter the sausage crumbles and the two varieties of shredded cheese over the biscuit base. In a separate bowl, whisk together the eggs, milk, and a pinch each of salt and pepper until thoroughly combined. Pour the egg mixture over the assembled layers in the baking dish. Bake for 25 to 30 minutes, or until the eggs are fully set and the center remains firm when gently shaken. Allow to rest for 5 minutes before slicing into squares and serving warm.
Notes
Biscuit Dough Option: If using homemade dough, pre-bake slightly to ensure full doneness.
Advance Preparation: Complete steps up to pouring in the egg mixture, cover the dish with foil, and refrigerate overnight. Uncover before baking, adding a few extra minutes to the cook time.
Storage Tips: Refrigerate leftovers in an airtight container for 3–4 days or freeze for up to 2 months.
