My favorite Biscuit Breakfast Casserole serves up sausage, eggs, peppers, and cheese on top of a buttery biscuit base. It’s super easy to make this casserole with a can of biscuits for a hearty way to start the day. My kids love this, and it’s a great thing to make for guests too.

This breakfast casserole with biscuits is the epitome of breakfast comfort food! And all I have to do is assemble it in the casserole dish then pop it in the oven. It can be made the night before and baked first thing in the morning, which is really convenient when I have holiday guests to feed.
Ingredients for Breakfast Casserole with Biscuits
- Biscuit Dough: Use 2 cans of refrigerated biscuit dough, cut into quarters This is the base of the casserole.
- Eggs: You’ll need 10 eggs to fill out this breakfast casserole.
- Milk: Helps create a pourable consistency for the egg mixture. Any kind of milk is fine–whole milk will be the creamiest.
- Cheese: Use shredded cheddar cheese, or your favorite type (pepper jack would be delicious!).
- Breakfast Sausage: Use cooked breakfast sausage, cut into bite-sized pieces. You can swap it for cooked bacon or ham if you like.
- Bell Pepper: Add diced red bell pepper, or any other veggies you like. Mushrooms are a great addition.
- Herbs & Spices: Use oregano, parsley, garlic powder, salt and pepper. Feel free to swap in your favorite herbs.
- Butter: Use melted, unsalted butter for the herb mixture. This adds a final kick of flavor on top.
Tips for Success
- Use a knife sprayed with non-stick oil to cut the biscuit dough into quarters. This will prevent the dough from sticking and stretching as you make the pieces.
- Cover the biscuit casserole with foil for part of the baking time (as instructed) to prevent the eggs from burning.
How to Store and Reheat
This casserole can be prepared up to 1 day in advance. Assemble the casserole, then cover tightly in foil and refrigerate overnight until ready to bake it in the morning. When baked straight out of the refrigerator, you’ll need to add a minute or 2 to the baking time.
Store leftover biscuit breakfast casserole in an airtight container in the refrigerator for up to 3 days. Reheat in the oven until warmed through.
It can be frozen whole or cut into slices, for up to 2 months. Reheat from frozen in the microwave.
Serving Suggestions
Biscuits, cheese, eggs, and sausage make a pretty satiating casserole for breakfast, but I still like to add some breakfast potatoes to fill out the table.
