Notes

  • Sauté vegetables thoroughly: Cook until the peppers and mushrooms release their moisture to avoid a watery casserole.
  • Layer spinach raw: There's no need to pre-cook the spinach, baking will wilt it perfectly.
  • Mix cheese throughout: Stirring some cheese into the veggie layer ensures even flavor, while topping adds a golden finish.
  • Whisk eggs well: Beat until fully blended for a uniform texture and better rise.
  • Let it rest before slicing: Allow the casserole to cool for 5–10 minutes after baking so it sets and slices cleanly.
  • Use a glass or ceramic dish: These materials help cook the casserole more evenly than metal pans.
