Ingredients
  

For the Casserole
  • 1 tablespoon olive oil
  • 14 to 16 ounces uncooked pork breakfast sausage
  • 12 large eggs
  • 2 cups half-and-half
  • 2 teaspoons dry mustard
  • 1.5 teaspoons kosher salt
  • 0.5 teaspoon freshly ground black pepper
  • 8 ounces sharp cheddar cheese, shredded preferably white, about 2 cups
  • 6 slices hearty white sandwich bread about 8 to 9 ounces

Equipment

  • Large skillet
  • 9x13-inch baking dish
  • Whisk
  • Large bowl

Method
 

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9x13 inch baking dish with cooking spray or olive oil.
  2. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the breakfast sausage and cook, breaking it up with a spoon, until browned and cooked through. Drain off any excess grease.
  3. In a large bowl, whisk together the eggs, half-and-half, dry mustard, kosher salt, and black pepper until well combined.
  4. Tear the bread slices into bite-sized pieces and place them in the prepared baking dish. Scatter the cooked sausage and shredded cheddar cheese over the bread.
  5. Pour the egg mixture evenly over the bread, sausage, and cheese in the baking dish. Gently press down on the bread to ensure it is mostly submerged in the liquid.
  6. Cover the baking dish with plastic wrap and refrigerate for at least 15 minutes, or up to overnight. This allows the bread to soak up the egg mixture.
  7. When ready to bake, remove the plastic wrap and place the dish in the preheated oven. Bake for 45 to 55 minutes, or until the casserole is set and lightly golden brown on top. A knife inserted into the center should come out clean.
  8. Let the casserole rest for 10-15 minutes before slicing and serving. This helps it hold its shape.

Notes

This casserole can be assembled the night before and refrigerated, making your morning easier. It reheats well, making it a great option for meal prep.
