This easy breakfast casserole with maple sausage is made with eggs, bread, and cheese for a simple, make-ahead breakfast that’s perfect for weekends or feeding a crowd.

This is one of those recipes that makes mornings feel a whole lot easier.

Everything goes into one dish, you pop it in the oven, and somehow it comes out tasting like you put in way more effort than you actually did. No standing at the stove, no flipping anything… just bake, slice, and serve.

I made this with maple sausage because that’s what I had on hand, and it ended up being one of my favorite parts. It adds just a little sweetness that works so well with the eggs and cheese.

It’s simple, filling, and the kind of breakfast that disappears fast once it hits the table.

This is the kind of breakfast that pairs perfectly with something simple on the side, like fresh fruit or a slice of my lemon blueberry loaf.

How to Make This Easy Breakfast Casserole

Cook the sausage

In a skillet over medium heat, cook the maple sausage, peppers, and onion until sausage is browned and fully cooked. Drain excess grease if needed.

Prepare the egg mixture

In a large bowl, whisk together the eggs, milk, salt, and pepper until well combined.

Assemble the casserole

Grease a 9×13 baking dish.

Add the cubed bread, cooked sausage, and shredded cheese. Pour the egg mixture evenly over the top.

Gently press everything down so the bread soaks up the liquid.

Bake

Bake at 350°F for 40–45 minutes, or until the center is set and the top is lightly golden.

The top gets lightly golden while the inside stays soft and a little custardy, which is exactly what you want.

Easy breakfast casserole with sausage and cheese

Let it sit for about 5–10 minutes before slicing.

It slices best after sitting for a few minutes, otherwise it’s a little too soft right out of the oven.
