These fluffy, tender egg muffins are packed with spinach and cheddar cheese, perfect for meal prep and busy mornings. They reheat beautifully and are endlessly customizable.
Do not overmix the eggs; whisk just until combined. Use room temperature eggs for best texture. Let muffins cool completely before storing to avoid sogginess. For freezing, place cooled muffins on a baking sheet and freeze for 1 hour, then transfer to a freezer-safe bag. Reheat in a toaster oven or air fryer at 350°F for 5-7 minutes.
