Fold the sautéed onion and spinach into the egg mixture, gently combining them until evenly distributed. This will ensure every bite is packed with delicious goodness!

Layer the sliced cherry tomatoes in the muffin tin, followed by spooning the egg mixture over them. Fill each cup generously, but leave a bit of space for rising.

Spinach and Cheddar Egg Muffins Recipe FAQs
How can I tell if my spinach is fresh?
Absolutely! When selecting spinach, look for vibrant, dark green leaves that are crisp and free of dark spots or yellowing. Fresh spinach should feel cool to the touch, indicating it hasn’t wilted. If you see dark spots or slimy leaves, it’s best to skip those!
What’s the best way to store leftover muffins?
Very! Store your Spinach and Cheddar Egg Muffins in an airtight container in the refrigerator. They’ll stay fresh for up to 3 days, offering a convenient grab-and-go breakfast option. Just reheat in the microwave for 1-2 minutes, and they are good as new!

Can I freeze Spinach and Cheddar Egg Muffins?
Of course! To freeze, wrap each muffin individually in plastic wrap and then place them in a freezer-safe bag or container. They can be stored in the freezer for up to 3 months! When you’re ready to eat, thaw overnight in the fridge, then reheat in the microwave or oven. This method preserves their flavor and texture beautifully.
What can I substitute if I have allergies?
If you’re dealing with allergies, no worries! For those avoiding dairy, consider using a dairy-free cheese alternative and unsweetened almond milk instead of regular milk. If egg allergies are a concern, you might try using a flaxseed mixture (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water) to replace one egg. Each of these substitutions maintains the muffins’ deliciousness!
What if my muffins come out too dry?
Don’t fret! If your Spinach and Cheddar Egg Muffins turn out dry, it might be due to overbaking. To prevent this, always keep an eye on them towards the end of the bake time, as ovens vary. Look for a golden hue and ensure the eggs are just set. You can also add a touch more milk next time for extra moisture!
Can I use frozen spinach instead of fresh?
Absolutely! Frozen spinach works well in this recipe. Just make sure to thaw it and squeeze out any excess water before adding it to the mixture. You may need about 3 ounces of frozen spinach to replace the fresh, ensuring that your muffins remain flavorful and don’t become too watery.
