These easy make-ahead cheddar spinach egg muffins are a quick, nutritious, and delicious breakfast option that can be prepared in advance and enjoyed throughout the week.
Do not overfill muffin cups to prevent spilling. Use room temperature eggs for fluffier texture. If using frozen spinach, thaw and squeeze out excess water. Tent muffins with foil if browning too quickly. Let muffins cool before removing from tin to avoid breakage. Silicone molds can be used for easier removal and freezing.
