Why This Recipe Works
What I love about this casserole is how simple it is. We're talking about frozen biscuits, some eggs, and cooked sausage - pretty straightforward, right? The magic happens when you mix everything together. The biscuits soak up the egg mixture, creating that lovely texture you want in a breakfast bake. Plus, the combination of flavors is spot on.

The garlic powder adds a nice kick without being overpowering, and the cheddar cheese gives it that gooey, melty goodness we all crave.
Ingredients
To whip this up, you'll need:
- 6 frozen biscuits
- 4 large eggs
- ½ cup whole milk or heavy cream (I usually go for the cream for extra richness)
- ½ teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- ½ cup shredded cheddar cheese
- ½ pound breakfast sausage, cooked and crumbled

I like to keep the ingredients simple and straightforward, so you probably have most of these in your pantry already.
How to Make It
First things first, preheat your oven to 375 degrees F. This is key because you want that oven nice and hot when the casserole goes in.
Next, grab an 8x8-inch casserole dish and place your frozen biscuits in there. I just toss them in whole, but if you're feeling fancy, you can cut them into quarters for a more spread-out effect.

In a mixing bowl, whisk together the eggs, milk or cream, salt, black pepper, and garlic powder. I really like to make sure everything is well combined; it makes a difference in the final product. Pour this mixture evenly over the biscuits. Don’t worry if it looks a little messy at this point - that's part of the charm.
Now for the fun part: sprinkle the shredded cheddar cheese over the top. You can never have too much cheese in my book. Then, add the cooked and crumbled breakfast sausage. I usually cook mine in a skillet first to get it nice and crispy, but if you have leftovers from breakfast, they work perfectly here too.

Pop the casserole into the oven and bake for about 35 to 40 minutes. Keep an eye on it - you want the eggs to be fully set and the biscuits cooked through. If you notice the tops of the biscuits browning too quickly, just loosely cover the dish with aluminum foil. This way, you won’t end up with burnt tops while waiting for the inside to set.
Once it’s done, let it cool for about 10 minutes before serving. This is an important step. It allows the casserole to firm up a bit and makes it easier to cut. Plus, it won’t scald your mouth when you dive in.

Tips / Variations
Here’s where you can get a little creative. I like to switch things up with different types of cheese. Sometimes I’ll use pepper jack for a bit of heat, or even mix in some cream cheese for extra creaminess. If you want to add some veggies, diced bell peppers or spinach can sneak in some nutrients without anyone noticing.
If you're looking for a lighter version, you can use egg whites instead of whole eggs and low-fat milk. It’ll still taste great, just a little lighter on the waistline.

Serving Ideas
This casserole is perfect for brunch gatherings or even as a make-ahead breakfast for busy weekdays. I’ve served it alongside fresh fruit or a simple green salad to balance out the richness. You can easily double the recipe if you’re expecting a crowd, and trust me, it’s a crowd-pleaser.

Yes, you can prepare the casserole the night before and store it in the refrigerator. Just cover it tightly with plastic wrap or aluminum foil. When you are ready to bake it, remove it from the fridge and allow it to sit at room temperature for about 30 minutes before baking. Store any leftover Biscuit Sausage Breakfast Casserole in an airtight container in the refrigerator for up to 3-4 days. You can also freeze it for up to 3 months. To reheat the casserole, preheat your oven to 350F. Place the casserole in an oven-safe dish, cover it with foil to prevent it from drying out, and heat for about 20-30 minutes or until heated through. Yes, you can substitute the breakfast sausage with cooked bacon or ham, and the cheddar cheese can be replaced with your favorite cheese. You can also use dairy-free milk or a milk alternative if you want to make it lactose-free. Using a different type of biscuit may change the texture slightly. For instance, using flaky biscuits will yield a lighter casserole, while using buttermilk or whole wheat biscuits may create a denser texture. Just make sure the biscuits are frozen as the recipe specifies for best results.Frequently Asked Questions
