These easy make-ahead egg muffin cups with spinach and cheese are a quick, nutritious, and customizable breakfast solution perfect for busy mornings. They are fluffy, flavorful, and travel well for on-the-go meals.
Use room temperature eggs for better rise and even cooking. Avoid excess moisture in spinach by patting dry or sautéing and draining. Grease muffin tins well to prevent sticking. If tops brown too quickly, tent with foil and continue baking. For dairy-free, substitute milk with almond or oat milk and cheese with nutritional yeast or vegan cheese. Muffin cups can be frozen for up to 2 months and reheated gently.
