A warm, cheesy, and crowd-pleasing brunch casserole that you can prep the night before, perfect for a stress-free family breakfast or weekend gathering.

Ingredients

Scale
  • 10 large eggs
  • 1 ½ cups (360 ml) whole milk
  • 2 cups (200 g) shredded sharp cheddar cheese
  • 1 pound (450 g) breakfast sausage (mild pork or turkey sausage)
  • 6 cups (about 8 ounces) cubed day-old bread (sourdough or French bread)
  • 4 green onions, sliced
  • Salt and pepper to taste
  • 1 teaspoon dried Italian seasoning or dried thyme

Instructions

  1. Brown the sausage in a skillet over medium heat for 7–8 minutes until no longer pink and nicely browned. Drain excess fat on paper towels.
  2. Cube the day-old bread into roughly 1-inch pieces and slice the green onions thinly.
  3. In a large mixing bowl, whisk eggs and milk vigorously until combined and slightly frothy.
  4. Add the browned sausage, bread cubes, green onions, shredded cheddar, Italian seasoning, salt, and pepper to the egg mixture. Stir gently until the bread is evenly coated and everything is well distributed.
  5. Transfer the mixture to a greased 9×13-inch baking dish. Cover tightly with foil or plastic wrap and refrigerate overnight or at least 4 hours.
  6. Preheat oven to 350°F (175°C). Remove casserole from fridge 15 minutes before baking.
  7. Bake covered for 30 minutes, then uncover and bake another 15–20 minutes until the top is golden and a knife inserted comes out clean.
  8. Let the casserole rest for 5 minutes before slicing and serving warm.

Notes

[‘Use day-old bread to avoid sogginess; if using fresh bread, toast lightly first.’, ‘Season well with salt and pepper for best flavor.’, ‘Let the casserole soak overnight or at least 4 hours for best texture.’, ‘Remove from fridge 15 minutes before baking to take the chill off.’, ‘Avoid overbaking to keep casserole moist; cover with foil if browning too fast.’, ‘Reheat leftovers in a skillet with a splash of milk or cream to keep creamy.’]
