How to Make Breakfast Egg Muffins

This simple keto recipe is made with eggs, almond milk, fresh spinach, tomatoes, green onions and cheddar cheese. The best part of all is that the recipe is so effortless!

All you do is mix together all of your ingredients, pour them in a muffin pan and then bake until the egg muffins are set. I also like to top them with some sliced avocado (to add more healthy fats and also for presentation) when I am ready to serve or eat them, but that is completely optional.

How to Store, Freeze, and Reheat Breakfast Egg Muffins

These Breakfast Egg Muffins are great for meal prepping on Sundays because you can make a batch, store it in the fridge and enjoy it for the next few days. They are also ideal for a brunch buffet, as you can make them ahead of time and reheat when you are ready to serve. They can be stored for up to three days in the refrigerator and three months in the freezer (just remember not to add the avocado, if using, until you are ready to eat them!)

To Store in the Refrigerator: Allow the egg muffins cool off completely, then place them in a sealed, airtight container. You can store all of the egg muffins together in one large container or portion each one into individual containers. Alternatively, you can wrap the egg muffins in plastic wrap or store them in zipped-top plastic bags.
To Store in the Freezer: Allow the egg muffins cool off completely, then wrap each one individually in plastic wrap. Place them in a freezer-safe zipped-top bag and place in freezer.
To Reheat from Refrigerated or Frozen: Unwrap the muffins, if needed, and place on a microwave-safe plate. Reheat in the microwave until warmed through to the center, for about 30 seconds (from thawed) or 1 to 2 minutes (from frozen).*

*The exact cook time you need to reheat the breakfast egg muffins will vary based on the power of your microwave.

Here are a couple of tools I suggest using when making this recipe:

Box grater – You can save a ton of money by grating a brick of cheese yourself, rather than buying pre-shredded cheese. Pre-shredded cheese also contains additives that prevent the cheese from sticking together in the bag. So if you grate the cheese yourself, it will melt better too!
6-cup muffin pan – This pan is the perfect size for this recipe. I love using it because its small enough to fit inside of my toaster oven, which heats up so much faster than my actual oven!
