Print Recipe

A simple, hearty breakfast casserole combining sausage, eggs, cheese, and bread soaked overnight for a custardy texture and baked to golden perfection. Perfect for busy mornings or lazy weekends.

Ingredients

Scale
  • 1 pound ground breakfast sausage (mild pork sausage recommended)
  • 8 large eggs, room temperature
  • 2 cups whole milk (or 2% milk)
  • 2 cups shredded cheddar cheese (sharp or mild; optional mix with mozzarella)
  • 4 cups cubed day-old bread (about 6–7 slices, thick-cut white or sourdough)
  • 1 tablespoon Dijon mustard
  • Salt to taste (about 1 teaspoon)
  • Freshly ground black pepper to taste (about ½ teaspoon)
  • Optional: chopped green onions or fresh herbs (a handful)

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. Brown the sausage in a skillet over medium heat until no longer pink, about 7-9 minutes. Drain excess fat and set aside to cool slightly.
  3. In a large mixing bowl, whisk together 8 eggs, 2 cups milk, 1 tablespoon Dijon mustard, salt, and black pepper.
  4. Cube the day-old bread into bite-sized pieces. If using fresh bread, toast lightly to help it hold up.
  5. Spray a 9×13-inch baking dish with cooking spray or rub lightly with butter.
  6. Spread half of the bread cubes evenly in the bottom of the dish. Sprinkle half of the cooked sausage and half of the shredded cheese over the bread.
  7. Repeat the layers with the remaining bread, sausage, and cheese.
  8. Pour the egg mixture evenly over the layered ingredients. Press down gently to help the bread soak in the liquid.
  9. Cover the dish tightly with plastic wrap or foil and refrigerate for at least 6 hours or overnight.
  10. Remove from fridge and let sit at room temperature for 15 minutes before baking.
  11. Bake uncovered for 45-50 minutes until the top is golden brown and eggs are set (a knife inserted should come out clean).
  12. Let the casserole rest for 5-10 minutes before slicing and serving.

Notes

Use day-old bread or lightly toasted fresh bread to avoid sogginess. The overnight soak is key for custardy texture. If top browns too quickly, tent with foil halfway through baking. Let casserole rest before slicing to firm up. Variations include vegetarian, spicy, low-carb, and dairy-free options.
