Everyone should have those go-recipes in their recipe box that are tried and true and can be depended on time and time again.

This Make-Ahead Breakfast Casserole is just that.

It’s perfect for Christmas morning, Sunday brunch, or a pot-luck.

I first stumbled upon this recipe from Jimmy Dean years ago and clipped it from a magazine for my recipe binder. (That sentence makes me feel old.)

10-plus years later, it’s still one of my favorite breakfasts to share with a crowd.

When I was teaching, we often had early morning, potluck-style breakfast meetings on teacher work days.

We’d all bring a dish to share and this casserole was my go-to because it’s so easy, but it was always one of the first things to disappear.

Okay, the bacon was always the first thing to disappear, but this casserole was a close second.

Even though there are a number of potato breakfast casserole recipes out there, my Make-Ahead Breakfast Casserole is made with bread as the base along with the eggs. 

The bread soaks up the eggs overnight and it almost ends up like a savory French toast casserole.

Making this Make-Ahead Breakfast Casserole is so easy, you can practically do it in your sleep.

All you need to do is cook the sausage, and then layer it into a baking dish with the cubed bread, cheese and veggies. I like to toast my bread while the sausage is cooking, but that’s completely optional.

From there, just whisk together eggs with some milk and seasoning, and pour them over the rest of the casserole. After a rest in the fridge, it’s ready to bake.

When I was taking this to work, I would prep everything the night before, refrigerate it overnight and then pop it into the oven while I got ready for work.

I’d cover it with foil and it would still be piping hot by the time our meeting started.

In addition to the bread and eggs, I like to load up this breakfast casserole with sausage, cheese, and red bell peppers.

But you can totally customize it by adding in all sorts of vegetables like mushrooms, onions, jalapeno peppers, or tomatoes to make it even more flavorful.

Don’t like sausage? No problem! Try frying up a pound of bacon and crumbling it into the casserole instead.

You can also try making cinnamon rolls ahead! I love Overnight Toffee Cinnamon Rolls and Overnight Chai Spice Sweet Rolls.

And of course, there’s always granola. Whip up some Salted Dark Chocolate Granola ahead of time, and serve with berries, milk or yogurt in the morning.

Serve any of these make-ahead breakfast recipes with Make-Ahead Breakfast Casserole and spend the morning enjoying a feast, instead of cooking away in the kitchen.

Make-Ahead Breakfast Casserole

Yield: 8 servings
Prep Time: 15 minutes
Cook Time: 55 minutes
Total Time: 1 hour 10 minutes

Make-Ahead Breakfast Casserole is loaded with sausage, cheese and eggs. Assemble it the night before for a simple, delicious breakfast in no time!


  • 1 (16 ounce) package pork sausage
  • 10 eggs, lightly beaten
  • 3 cups milk
  • 1 teaspoon salt
  • 6 cups cubed bread*
  • 2 cups shredded sharp Cheddar cheese
  • 1/2 teaspoon black pepper
  • 1/2 cup diced red pepper, optional
  • sliced green onion, optional


  1. Butter a 9 x 13 x 2 inch casserole dish.
  2. In large skillet, cook sausage over medium-high heat, stirring frequently until thoroughly cooked and no longer pink.
  3. In large bowl, whisk together eggs, milk, and salt until thoroughly combined.
  4. Evenly distribute half the bread into the prepared casserole dish. Sprinkle with half the cheese, half the black pepper, half the red pepper, and half the sausage. Repeat layers.
  5. Pour egg mixture evenly over casserole.
  6. Cover and refrigerate overnight, or bake immediately.
  7. When you're ready to bake the casserole, preheat oven to 325 F. Bake uncovered for 55-60 minutes, or until eggs are set. If the top begins to brown too quickly, loosely cover the casserole dish with foil.
  8. If desired, sprinkle the casserole with sliced green onions. Serve warm.


*I toast my bread before incorporating it into the casserole, but this step is optional.
