These easy make-ahead egg muffins with spinach and cheddar are a quick, healthy breakfast option that can be prepared in advance and enjoyed throughout the week.
Do not overfill muffin cups to avoid spills; fill about ¾ full. Whisk eggs and milk until frothy for lighter muffins. If using frozen spinach, squeeze out excess water to prevent soggy muffins. Rotate muffin tin halfway through baking for even cooking. Cover with foil halfway if muffins brown too quickly. For mini muffins, reduce baking time to 12-15 minutes.
