Ingredients

Scale
  • 6 cups day-old bread cubes (crusty white or sourdough loaf, toasted lightly)
  • 6 large eggs (room temperature)
  • 2 cups whole milk (can substitute 2% or oat milk)
  • 1 cup shredded sharp cheddar cheese (about 100 g)
  • Salt and black pepper to taste
  • 1 lb ground breakfast sausage (slightly spicy variety preferred)
  • 3 tablespoons unsalted butter (about 42 g)
  • 3 tablespoons all-purpose flour (about 24 g)
  • 3 cups whole milk (warmed, about 720 ml)
  • Pinch of cayenne pepper
  • Optional garnishes: chopped fresh parsley or chives, hot sauce or red pepper flakes

Instructions

  1. Preheat oven to 350°F (175°C). Cut day-old bread into 1-inch cubes. Spread on baking sheet and toast for about 10 minutes until crispy but not browned.
  2. In a medium bowl, whisk together eggs, 2 cups whole milk, salt, and black pepper. Stir in shredded cheddar cheese and set aside.
  3. Heat a large skillet over medium heat. Add ground sausage, breaking it apart, and cook until browned and cooked through, about 7–8 minutes. Remove sausage with slotted spoon and set aside, leaving fat in pan.
  4. Add butter to sausage fat in skillet and melt over medium heat. Sprinkle in flour and whisk continuously for about 2 minutes to form a roux.
  5. Slowly pour in 3 cups warm milk, whisking constantly to avoid lumps. Simmer gently until thickened, about 5–7 minutes. Season with salt, black pepper, and cayenne pepper. Stir cooked sausage back into gravy.
  6. Lightly grease a 9×13-inch baking dish. Spread toasted bread cubes evenly in dish. Pour egg and cheese mixture over bread, pressing gently to soak. Ladle creamy sausage gravy evenly over the top.
  7. Bake uncovered at 350°F (175°C) for 35–40 minutes until eggs are set and edges are golden. Let rest for 5 minutes before serving.
  8. Garnish with chopped parsley or chives and add hot sauce or red pepper flakes if desired.

Notes

Warm the milk before adding to the roux to prevent lumps. Toast bread cubes to avoid sogginess. Let casserole rest after baking for easier serving. Tent with foil if browning too quickly. For gluten-free, substitute bread and flour accordingly. Vegetarian version uses sautéed mushrooms and vegetable broth gravy.
