Sausage Breakfast Casserole

Prepare breakfast casserole in advance

You can assemble it the night before and just pop it in the oven in the morning. As a chef, you can enjoy the morning’s festivities with your guests instead of frolicking around in the kitchen.

This recipe is inspired by a Jimmy Dean sausage ad pulled from a magazine 20 years ago.

Cut into squares to serve!

Tip: use bread from the day before

Slightly dry bread keeps better in the casserole and provides more structure, which is why breakfast casseroles tend to call for “day-old” bread. If your bread is fresh or soft, after dicing, spread it out on a baking sheet and place in a 200°F oven for 10 to 12 minutes.

Mix the fillings

This recipe is very customizable. Leave the base of the recipe as is — ten eggs, four cups of milk, and five cups of bread cubes — and feel free to play around with the rest.

Replace the ground sausage with ground beef, shredded chicken, or leftover diced ham. Swap out the cheddar for something like Swiss or Monterey Jack. And instead of mushrooms or tomatoes, you can use chopped peppers, zucchini or any other greens. If you have leftover boiled potatoes or sweet potatoes, these are also a good addition.

What to serve with the breakfast casserole

A breakfast casserole like this makes a great part of a brunch buffet for a house full of guests. Add in a platter of sliced ​​fruit, some yogurt and granola, and some breakfast pastries, and you’re all set. Don’t forget the coffee.

This is how you can tell when the breakfast casserole is ready

Insert a skewer or toothpick into the center of the casserole. When fully cooked, the skewer will come out dry, not wet. If it still hasn’t set in the center, loosely cover the pan with foil after baking to keep the top from drying out.

Note: The more additions, the longer the casserole will take to bake.

How to freeze a breakfast casserole

You can bake and freeze this to reheat later.

Slightly dry bread keeps better in the casserole and provides more structure, which is why breakfast casseroles tend to call for “day-old” bread. If your bread is fresh or soft, after dicing, spread it out on a baking sheet and place in a 200°F oven for 10 to 12 minutes.


  • 1 lb Iitalian pork sausage

  • 10 big eggs, beaten

  • 4 cups whole milk

  • 1 teaspoon dry mustard

  • 1/4 teaspoon onion powder

  • 1 teaspoon kosher salt

  • Fresh floor Black pepper to taste

  • 5 cups diced day-old bread (like rustic French or Italian bread), cut into 3/4 to 1 inch cubes

  • 2 cups shredded sharp cheddar cheese

  • 1/2 Cup sliced ​​mushrooms, Optional

  • 1/2 Cup peeled, cored, chopped Tomatoes, Optional


  1. Brown the Sausage:

    Heat a pan on medium-high. Break the sausage into pieces and cook in batches, if necessary, until cooked on all sides. As you cook the sausage, you can break the larger pieces into smaller crumbles (which are easier to spread evenly throughout the casserole).

    When lightly browned, remove from the pan onto a plate lined with kitchen paper to absorb excess fat.

  2. Whisk together eggs, milk and spices:

    In a large bowl, whisk together the eggs, milk, dry mustard, onion powder, salt, and pepper

  3. Assemble casserole:

    Place the diced bread in a well-buttered 9 x 13 inch baking pan. Sprinkle with cheese. Sprinkle with chopped tomatoes and mushrooms, if using. Top with the browned crumbled sausage and spread evenly. Pour the egg and milk mixture evenly over the bread and cheese.

  4. Cover and refrigerate if you are making beforehand:

    At this point, the casserole can be covered and chilled in the refrigerator for several hours or overnight until ready to bake and serve.

    If baking immediately, allow the casserole to rest for 10 minutes to allow the bread to absorb the milk and egg mixture before placing in the oven.

  5. Preheat the oven:

    When ready to bake, preheat the oven to 325°F.

  6. Bake the casserole:

    Bake uncovered for about 1 hour. Tent with foil if the top starts to brown too quickly.

  7. Surcharge:

    Allow the casserole to cool for about 10 minutes before serving. Leftovers will keep in the fridge for about a week.
