I love how easy this casserole is to whip up. Just throw everything together, pop it in the oven, and in no time, you have a warm, filling meal. Who can resist cheesy goodness? 😋
Key Ingredients & Substitutions
Refrigerated Flaky Biscuits: These are the star of the dish! They provide fluffy texture. If you can’t find them, try using homemade biscuit dough or other types of refrigerated dough like crescent rolls.
Breakfast Sausage: Crumbled sausage adds flavor and protein. If you want a lighter option, turkey sausage works great. For a vegetarian version, just skip it or use sautéed veggies instead.
Cheddar Cheese: I love the sharpness of cheddar in this casserole. You can choose mild cheddar for a subtler taste or switch to Monterey Jack for creaminess. Mixing different cheeses like pepper jack can add a fun twist!
Milk: Whole milk gives the best creaminess, but you can substitute with low-fat milk, almond milk, or even cream for a richer blend. Just remember that thinner alternatives may adjust the texture a bit.
How Do You Cut and Layer the Biscuits Perfectly?
Getting the biscuits cut and layered right sets the base for your casserole. Start by opening the can of refrigerated biscuits and using a sharp knife or kitchen scissors to cut each biscuit into quarters. This ensures even cooking and makes them soak up the egg mixture nicely.
- Use a greased or non-stick baking dish to prevent sticking.
- Spread the biscuit pieces evenly across the dish. Try not to overlap them too much for even cooking.
- Gently push them down, so they’re nestled together, but don’t compact them too tightly!
This way, each biscuit piece gets its share of that delicious egg mixture and stays fluffy in the casserole.

Ingredients You’ll Need:
For the Casserole:
- 1 can (16 oz) of refrigerated flaky biscuits
- 1 cup cooked breakfast sausage, crumbled (optional: substitute with cooked bacon or omit for vegetarian)
- 1 cup shredded cheddar cheese
- 4 large eggs
- 1 cup milk
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/2 tsp dried parsley or Italian seasoning (optional)

How Much Time Will You Need?
This delicious breakfast casserole requires about 15 minutes for prep and 35-40 minutes for baking. So, in about an hour, you can have a warm, cheesy breakfast ready to serve!
Step-by-Step Instructions:
1. Preheat the Oven and Prepare the Dish:
Start by preheating your oven to 350°F (175°C). While it heats up, lightly grease a 9×9 inch baking dish or a similar sized casserole dish to prevent sticking.
2. Cut and Arrange the Biscuits:
Open the can of flaky biscuits and cut each one into quarters. Then, spread the biscuit pieces evenly in the greased baking dish. They should be nicely arranged to form a solid base.
3. Add Sausage and Cheese:
If you’re using sausage (or bacon), sprinkle it evenly over the biscuit pieces. Next, add 1 cup of shredded cheddar cheese on top of the sausage and biscuits for that cheesy goodness.
4. Whisk the Egg Mixture:
In a medium bowl, combine the eggs, milk, salt, pepper, and optional dried parsley or Italian seasoning. Whisk until everything is mixed well, then pour this mixture evenly over the biscuits, sausage, and cheese. Make sure it covers everything nicely!
5. Top with Extra Cheese:
Finally, sprinkle an additional 1 cup of shredded mozzarella or cheddar cheese on top of the entire casserole. This will create a deliciously cheesy crust as it bakes.
6. Bake and Enjoy:
Place the dish in your preheated oven and bake for about 35-40 minutes. You’ll know it’s done when the casserole is set, and the biscuit tops are golden brown. Let it cool for a few minutes, then serve warm by scooping portions with a spatula. Enjoy your tasty breakfast treat!
This Lazy Biscuits Breakfast Casserole is perfect for making ahead and feeding a crowd with minimal effort!
Can I Use Frozen Biscuits Instead of Refrigerated Ones?
Absolutely! If you’re using frozen biscuits, thaw them first according to the package instructions. Once thawed, cut them into quarters and follow the recipe as usual for a delicious result.
Can I Make This Casserole Vegetarian?
Yes, you can easily adapt this recipe for a vegetarian option. Just omit the sausage and consider adding more veggies like spinach, bell peppers, or mushrooms for added flavor and nutrition.
How to Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm it in the microwave or bake it in the oven at 350°F (175°C) until heated through.
Can I Add Additional Toppings?
Definitely! Feel free to customize your casserole with toppings like diced tomatoes, green onions, or even different types of cheese. Just sprinkle them on before baking to let the flavors meld together.
