Get ready for a breakfast bonanza with this show-stopping Cheesy Biscuit Breakfast Casserole. It’s the ultimate morning masterpiece, packed with all the good stuff: eggs, sausage, cheese, and biscuits – all in one glorious dish!
This casserole is the perfect solution for busy weekends and holidays when you need a hearty, satisfying meal to fuel up for the day ahead. And the best part? It’s ridiculously easy to make and can be prepped ahead or even frozen for later.
So, let’s dive into the nitty-gritty of making this breakfast behemoth. First, preheat your oven to 350°F. While that’s warming up, cook your sausage in a large skillet over medium-high heat, breaking it up into tiny pieces as it cooks. Once it’s browned and cooked through, drain the excess fat and set it aside.
Next, whisk together your eggs, milk, and a pinch of salt and pepper in a large bowl. Yes, it’s that simple. Now, grab your 9×13-inch baking dish and add half of the cooked sausage to the bottom. Top that with half of the shredded cheese and half of the biscuit pieces.
Now it’s time to pour in the egg mixture, making sure to cover the entire dish evenly. Don’t worry if it gets a bit messy – that’s half the fun! Sprinkle the remaining sausage, cheese, and biscuit pieces on top of the egg mixture.
Pop that casserole into the oven and bake for 25-30 minutes, or until the eggs are set and the top is golden brown. You can check if the eggs are cooked by inserting a butter knife into the center of the casserole – if it comes out clean, you’re good to go!

While the casserole is baking, you can prep your toppings. Chop up some fresh herbs, like parsley or chives, and have them ready to sprinkle on top of the casserole as soon as it comes out of the oven.
Once the casserole is done, remove it from the oven and let it cool for a few minutes. Sprinkle those fresh herbs on top and serve it up. You can also add some diced ham, bacon, or even diced bell peppers to give it an extra boost of flavor.

This casserole is perfect for a crowd, and it’s also a great way to use up any leftover ingredients you have on hand. So go ahead, get creative, and make it your own!
And don’t worry about leftovers – this casserole freezes beautifully. Simply let it cool completely, then cover it with plastic wrap or aluminum foil and pop it in the freezer for up to 3 months. When you’re ready to reheat, simply thaw it overnight in the fridge and bake it in the oven until hot and bubbly.

This Cheesy Biscuit Breakfast Casserole is a game-changer for busy mornings. It’s easy, delicious, and perfect for a crowd. So go ahead, give it a try, and make it a part of your breakfast routine!
