Pro Tip
Assemble the casserole the night before, cover, and refrigerate. In the morning, just pop it in the oven — the extra time allows the eggs to fully absorb into the other ingredients, resulting in a creamier texture.

A well-built breakfast casserole delivers balanced macros and a wide spectrum of micronutrients from whole food ingredients.

Eggs

  • The protein backbone of this dish — complete amino acid profile for muscle support
  • Rich in vitamins D and B12 for bone health and energy

Vegetables (Bell Peppers, Spinach, Onions)
