Preparation

  • In a large bowl, whisk together eggs, milk, salt, black pepper, and optional garlic powder until well combined.
  • Evenly scatter the cooked sausage, bell peppers, and onion in the prepared baking dish.
  • Sprinkle ¾ cup of shredded cheddar cheese over the vegetable and sausage mixture, then pour the egg mixture over everything.
  • Sprinkle the remaining ¼ cup of cheese on top, and bake for 35-45 minutes until set and golden brown.
  • Allow the casserole to rest for 5-10 minutes before slicing and serving.
