Breakfast Egg Muffins with Bacon and Spinach: These muffins make a great breakfast, lunch, or a snack to pack up for work, school, or a picnic! Just use a regular muffin pan for this recipe!

I love that these breakfast egg muffins are very easy to make, and all the ingredients in them constitute, basically, a classic breakfast. These muffins have protein (eggs), meat (bacon), vegetables (spinach), and cheese. What not to like? These will keep you full for a long time!
And, if you want meatless egg muffins - I have this delicious recipe for breakfast egg muffins with mushrooms and spinach.

If you have a company staying at your house - these egg muffins are a great way to treat your guests to a fast, easy, and very delicious breakfast! Also, you can pack these muffins as a to-go breakfast, lunch, or snack to bring to work or school.

They are also gluten free!

I’m only get 10 muffins and have added an extra egg?
Did you fill the muffin cups 3/4 full? If you fill up the muffin cups 3/4 full (not to the brim) - then you'll get 12 muffins.
Delicious egg muffins. Made them yesterday and froze them for the week ahead.
These look so good! Want to make them this weekend!
Delicious, however, despite greasing muffin tin, I found them very difficult to remove from the pan.
Can paper cups be used or do you have another suggestion?
Use silicone muffin liners. They are a godsend for recipes like this!
I'm using diced ham with spinach and the small sweet peppers in different colors and half the cheese. I've done this before and they come out awesome. The first time I used the recipe as written and they were great. My husband uses it to eat on his way to work. Thanks for posting.
Linda, you are so welcome! I am glad you've been making and enjoying this recipe! Using diced ham with spinach and small sweet peppers sounds so good!
How do you store them ? Can they be froze ? How long do they last in the fridge.
You can freeze these. Store them refrigerated (in an air-tight container or wrapped in plastic wrap or in a plastic bag). They last 5 days if stored in the fridge.
How do you warm them up if made ahead? Making about 4 doz quichettes for baby shower (2 types). Would be great f I could make them day before.
You can definitely make these a day before. That's what I do - I make them ahead, refrigerate them, and then reheat when I need them. The best way to reheat them would be in the oven, especially if you're reheating many of them at one time.
Hi, mine came out great apart from the fact that it was all puffed up when i took it out the oven (looked stunning), then it fell flat.. what could i have done wrong? Overbeat the eggs?
I think it's normal for egg muffins to puff up after baking and then they settle back to normal size.
Can you use uncooked spinach?
Yes, I use fresh spinach in mine.
Wouldn’t fresh spinach have too much moisture? I steamed fresh spinach and used that after squeezing out moisture.
I prefer to use cooked and drained spinach.
These are very versatile muffins. Mde a batch and they were awesome.
So glad to hear that! Enjoy! 🙂
Can you leave out "most" of the cheese and still have them come out okay? I have a guest with a dairy sensitivity
In theory, you can leave all of the cheese out, and replace the volume with more spinach, for example. Leaving the cheese out won't ruin the texture - it will just affect the flavor and the volume of muffins. Maybe, add more bacon too, to add more saltiness throughout each muffin.
Can you use bacon bits/pieces instead of cooking the bacon outright?
Yes, you can. But I like to use bigger chunks of bacon, so I use cooked bacon and then chop it up.
If I make ahead for weekday breakfast, how long will they stay good in the fridge?
These will stay good in the fridge for about 5 days.
Can i refridgerate and heat in microwave? Also are the calories for 1 muffin or 2??
Yes, you can refrigerate the muffins and reheat them in microwave. The calories are for 1 muffin.
Just what I was looking for! I have a huge 'Pillow' of fresh Spinach, two dozen Organic eggs, and some 'Wright' thick bacon! I will add chopped red bell pepper, a dash of turmeric, black pepper, and top with Mozzarella, that is what I have on hand.
Next batch I will add Quinoa, sunflower seeds, etc.
Plan to top another batch with frags of Organic flax-seed corn chips. Optional: Paprika, garlic, Shallots, mushrooms, etc. Like a mini omelet but portable! Sounds so yummy! A new way to make a nutritious breakfast!
Thank You!
Wow, you have quite a plan for these breakfast egg muffins! I love all your ideas! Adding turmeric and chopped red bell pepper sounds so good! If you like quinoa, take a look at this recipe that uses quinoa, it makes a delicious breakfast: https://juliasalbum.com/quinoa-spaghetti-squash-and-bacon-fritters/
If I make ahead and freeze these, could you please tell me how to defrost and re-heat?
I've made them before - delicious) - but have served them right away. Thank you!
You can reheat these right in the oven - probably 15-20 minutes in the preheated oven at 350 F, not more.
