Brief Introduction
Egg casseroles are a classic breakfast solution for busy mornings. Instead of scrambling a dozen eggs individually, you bake them all at once with cheese, meat, and veggies for a filling, shareable dish. This recipe is inspired by the classic American “church potluck” or holiday brunch table — hearty, comforting, and always the first to disappear.
Step-by-Step Cooking Guide (Narrative Expansion)
Step 1: Eggs & Milk
Eggs are the backbone. Whisking with milk makes them fluffier and prevents rubbery texture.
Step 2: The Meaty Layer
Ham is traditional, but any protein works — sausage, bacon, or even turkey. Dice small for even distribution.
Step 3: Cheese Factor
Cheese not only adds flavor but also binds the casserole. Cheddar = sharpness, mozzarella = stretch, pepper jack = spice.
Step 4: Vegetables
Green onions add freshness. Spinach or peppers add color and nutrition. Potatoes make it heartier.
Step 5: Baking
The key is even baking. Too hot = dry eggs, too low = watery center. 375°F is the sweet spot.
Ingredient Details & Substitutions
- Eggs: Use 10 eggs + 1 cup liquid egg whites for lighter version.
- Ham: Swap with shredded rotisserie chicken, turkey, or plant-based sausage.
- Cheese: Use reduced-fat cheese for lighter macros.
- Milk: Almond milk works fine; cream makes it richer.
