A quick and easy crustless breakfast casserole featuring fluffy eggs, salty feta, and tender spinach. Perfect for spring brunches or busy weekday mornings, this recipe comes together in under 30 minutes with simple ingredients.
For best results, use room temperature eggs and squeeze spinach dry to avoid a watery casserole. A pinch of nutmeg enhances the flavor. If the top browns too quickly, tent with foil. Leftovers keep in the refrigerator for up to 4 days or freeze for up to 3 months.
