Before diving into specific recipes, let’s explore the essential ingredients that make up a delicious overnight egg casserole:

Eggs: The star of the show! Eggs provide protein, structure, and richness to the casserole. Use high-quality eggs for the best results.

  • Milk or Cream: Liquid adds moisture and helps bind the ingredients together. Whole milk creates a creamier casserole, while skim milk offers a lighter option.
  • Cheese: No casserole is complete without cheese! Grated cheddar, mozzarella, swiss, or a combination are all fantastic choices.
  • Vegetables: Add color, flavor, and nutrients with a variety of chopped vegetables. Popular options include bell peppers, onions, broccoli, spinach, and mushrooms.
  • Meat: Sausage, ham, bacon, or cooked shredded chicken can add a savory protein boost.
  • Bread: Diced bread, bread cubes, or croissants add texture and soak up the eggy goodness.
