This is the ultimate hands-off breakfast bake, perfect for feeding a crowd. The secret to its luxuriously tender, custardy texture is gently whisking the eggs without incorporating too much air. It’s a savory, cheesy, and satisfying meal that feels special but is simple to make.

Ingredients

Scale
  • 1 pound breakfast sausage, mild or spicy
  • 1 tablespoon olive oil or butter
  • 1 medium yellow onion, diced
  • 1 red bell pepper, diced
  • 6 large eggs
  • 2 cups whole milk
  • 1 teaspoon dry mustard powder
  • 1 teaspoon kosher salt
  • ½ teaspoon black pepper
  • ½ teaspoon garlic powder
  • 1 (16 ounce) loaf French or Italian bread, cut into 1 inch cubes (about 8 cups)
  • 2 cups shredded sharp cheddar cheese, divided
  • 1 cup shredded Monterey Jack cheese
  • Fresh chives or parsley, for garnish (optional)

Instructions

  1. Brown the sausage in a large skillet over medium heat until crumbled and cooked through. Remove with a slotted spoon.
  2. In the same skillet, add oil or butter and sauté the diced onion and bell pepper until softened, about 5 minutes.
  3. In a large bowl, gently whisk the eggs, milk, dry mustard, salt, pepper, and garlic powder just until fully blended and smooth. Avoid over-whisking to prevent a rubbery texture.
  4. Grease a 9×13 inch baking dish. Scatter the bread cubes evenly in the bottom.
  5. Top the bread with the cooked sausage and sautéed vegetables.
  6. Sprinkle with 1 ½ cups of the cheddar cheese and all of the Monterey Jack cheese.
  7. Slowly and evenly pour the egg custard mixture over the entire casserole. Gently press down any bread pieces to ensure they are soaked.
  8. Sprinkle the remaining ½ cup cheddar cheese on top. Cover and refrigerate for at least 20 minutes or overnight.
  9. When ready to bake, preheat oven to 350°F (175°C). Bake the casserole, uncovered, for 45 to 50 minutes, until the center is set and the top is golden brown.
  10. Let the casserole rest for 10 minutes before slicing and serving. Garnish with fresh herbs if desired.

Notes

For best results, use slightly stale bread. The casserole can be assembled the night before and baked in the morning. Letting it rest before baking allows the bread to fully absorb the custard.
