Easy Sheet Pan Sausage & Cheese Breakfast Casserole

Sheet Pan Sausage Breakfast Casserole - featured image

A hearty, comforting breakfast casserole made with day-old bread, savory sausage, and sharp cheddar cheese, baked on a sheet pan for maximum crispiness and easy cleanup.

Ingredients

Scale
  • 1 pound breakfast sausage (pork, links or bulk)
  • 1 large loaf French or Italian bread, cut into 1-inch cubes (day-old)
  • 10 large eggs
  • 1 cup heavy cream
  • 1 cup whole milk
  • 2 cups sharp cheddar cheese, shredded
  • 1 tablespoon Dijon mustard
  • 1 teaspoon dry mustard powder
  • 1 teaspoon garlic powder
  • 1 teaspoon smoked paprika
  • Salt and black pepper to taste
  • 2 tablespoons butter, melted

Instructions

  1. Preheat oven to 350°F (175°C). Grease an 18×13 inch rimmed sheet pan thoroughly with melted butter.
  2. In a large skillet over medium heat, cook the sausage until browned and cooked through. Break into small crumbles and drain excess grease if necessary.
  3. Spread the bread cubes evenly across the prepared sheet pan in a single layer.
  4. Sprinkle the cooked sausage crumbles evenly over the bread.
  5. In a large bowl, whisk together eggs, heavy cream, whole milk, Dijon mustard, dry mustard powder, garlic powder, smoked paprika, salt, and pepper until frothy.
  6. Pour the egg mixture evenly over the bread and sausage. Use a rubber spatula to gently press down on the bread to ensure it absorbs the liquid.
  7. Let the casserole sit for 10 minutes to allow the bread to soak up the eggs.
  8. Sprinkle the shredded cheddar cheese evenly over the top.
  9. Bake for 35-45 minutes until the top is golden brown and the center is set. Tent with foil if browning too quickly.
  10. Remove from oven and let rest for 5-10 minutes before cutting into squares and serving warm.

Notes

Use day-old bread to prevent a soggy texture. Let the casserole rest for 10 minutes after baking to allow the custard to set. Can be assembled the night before and refrigerated overnight.
