A quick and easy make-ahead breakfast casserole featuring sausage, eggs, and bread that soaks overnight for a custardy, comforting dish perfect for busy mornings.

Ingredients

Scale
  • 6 large eggs, room temperature
  • 2 cups whole milk (or almond milk for dairy-free)
  • 1 teaspoon salt
  • ½ teaspoon black pepper, freshly ground
  • 1 teaspoon dried sage
  • 1 teaspoon garlic powder
  • 1 pound (450g) breakfast sausage, mild or spicy
  • 6 cups cubed day-old bread (white or sourdough recommended)
  • Optional: 1 cup shredded cheddar or mozzarella cheese
  • Optional: ½ cup diced onion
  • Optional: 1 cup chopped bell peppers
  • Optional: Fresh parsley or chives for garnish

Instructions

  1. Cube about 6 cups of day-old bread into roughly 1-inch pieces and set aside.
  2. Heat a skillet over medium heat and cook 1 pound of breakfast sausage, breaking it up with a wooden spoon, until browned and no longer pink, about 8-10 minutes. Optionally sauté diced onions and bell peppers with sausage. Drain excess fat and let cool slightly.
  3. In a large bowl, whisk together 6 large eggs, 2 cups whole milk, 1 teaspoon salt, ½ teaspoon black pepper, 1 teaspoon dried sage, and 1 teaspoon garlic powder until fully combined.
  4. In a 9×13 inch baking dish, layer the cubed bread evenly. Sprinkle cooked sausage and optional veggies over the bread. If using, sprinkle 1 cup shredded cheese on top.
  5. Slowly pour the egg mixture evenly over the bread and sausage, pressing down gently with a spatula to help the bread absorb the liquid.
  6. Cover the dish tightly with plastic wrap or foil and refrigerate for at least 4 hours, preferably overnight.
  7. Preheat oven to 350°F (175°C). Remove casserole from fridge and let sit at room temperature for 15 minutes.
  8. Bake uncovered for 45-50 minutes or until the top is golden brown and the center is set (a knife inserted should come out clean).
  9. Let the casserole cool for 10 minutes before slicing. Garnish with fresh parsley or chives if desired.

Notes

For best texture, soak casserole overnight. Use day-old sturdy bread to avoid sogginess. Tent with foil if edges brown too fast. Can be customized with veggies, different cheeses, or vegetarian sausage alternatives. Refrigerate leftovers up to 3 days or freeze up to 2 months. Reheat in microwave or oven with a splash of water to keep moist.
