Ingredients
  

  • 6 large eggs: Can substitute with 9 egg whites for a lower-fat option.
  • 1 cup milk: Use whole milk for richness or substitute with almond milk or oat milk for a dairy-free option.
  • 1/2 cup shredded cheddar cheese: Experiment with other cheeses like Monterey Jack Colby, or pepper jack.
  • 1/2 cup chopped cooked bacon or sausage: Omit for a vegetarian option or use cooked breakfast sausage.
  • 1/2 cup chopped bell peppers: Any color works well; substitute with chopped spinach or mushrooms.
  • 1/4 cup chopped onion: Substitute with shallots or leeks for a milder flavor.
  • 1/4 teaspoon salt: Adjust to taste.
  • 1/4 teaspoon black pepper: Adjust to taste.
  • 1/4 cup bread crumbs: Panko breadcrumbs add a nice crispy texture; omit for a lower-carb option.

Instructions
 

  • Preheat oven to 350°F (175°C). Grease a 9x13-inch baking dish.
  • Whisk eggs and milk: In a large bowl, whisk together eggs and milk until light and frothy. Stir in salt and pepper.

  • Pour into baking dish: Pour the egg mixture into the prepared baking dish. Sprinkle with bread crumbs (if using).
