Description

Breakfast Egg Casserole is a hearty, customizable dish made with eggs, cheese, vegetables, and optional meats or potatoes. It’s ideal for meal prep, holiday brunches, or feeding a crowd with minimal effort.


Ingredients

  • 10 large eggs
  • 1 cup milk or half-and-half
  • 1 1/2 cups shredded cheese (cheddar, mozzarella, or a blend)
  • 12 cups diced vegetables (bell peppers, onions, spinach, mushrooms)
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1/2 tsp garlic powder or onion powder (optional)
  • 2 cups bread cubes, hash browns, or tater tots (optional base)
  • Fresh herbs for garnish (optional)

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 9×13-inch baking dish.
  2. In a large bowl, whisk together the eggs, milk, salt, pepper, and optional seasonings.
  3. Layer the bread cubes, hash browns, or tater tots in the bottom of the baking dish, if using.
  4. Evenly spread the cooked meat and chopped vegetables over the base.
  5. Sprinkle the shredded cheese over the meat and vegetables.
  6. Pour the egg mixture over the top, ensuring all ingredients are covered.
  7. Let the casserole sit for 10–15 minutes (or refrigerate overnight).
  8. Bake uncovered for 40–50 minutes, or until the center is set and the top is golden.
  9. Let cool for a few minutes before slicing and serving.

Notes

Customize with your favorite cheese, meats, or veggies.For a vegetarian version, omit the meat and add more vegetables.To make it dairy-free, use plant-based milk and cheese alternatives.Chilling the mixture overnight improves flavor and texture.Freeze individual portions for a grab-and-go breakfast option.
