Ingredients

Scale
  • 1 lb (450 g) halal beef or turkey breakfast sausage
  • 1 red bell pepper, diced
  • 6 cups cubed day-old bread
  • 2 cups shredded sharp cheddar, divided
  • 3 green onions, sliced
  • 10 large eggs
  • 2 cups whole milk
  • 1 tsp dry mustard
  • ½ tsp salt
  • ¼ tsp black pepper
  • ¼ tsp garlic powder
  • Fresh parsley, for garnish

Instructions

  1. Brown the sausage 7–8 minutes, adding the bell pepper for the last 2 minutes. Drain.
  2. Grease a 9×13-inch dish. Layer bread cubes, sausage mixture, green onions and 1½ cups cheese.
  3. Whisk eggs, milk, dry mustard, salt, pepper and garlic powder. Pour over the casserole and press the bread down.
  4. Cover and refrigerate overnight (at least 8 hours).
  5. Preheat oven to 350°F (175°C). Top with remaining cheese and bake uncovered 45–55 minutes, until set in the center.
  6. Rest 10 minutes, garnish with parsley and serve.

Notes

  • Use day-old bread so it soaks up the custard without getting soggy.
  • Cover with foil if the top browns too quickly.
