The secret to these Egg Muffins lies in their key ingredients. Each one brings something special to create three unique and flavorful versions of this breakfast staple. Let’s dive into what makes this recipe truly exceptional:
- Eggs: Start with the freshest, highest quality eggs you can find. Look for ones with a deep, rich yolk to ensure a creamy texture and vibrant flavor in your muffins.
- Spinach Tomato & Mozzarella: This combination offers a delightful mix of fresh, juicy tomatoes and tender spinach, balanced with the creamy goodness of mozzarella. Use ripe tomatoes and fresh spinach leaves for the best results.

Ready to whip up some delicious Egg Muffins? Follow these simple steps with images to guide you through the process. You’ll create fluffy, flavorful muffins with three unique flavor profiles that are perfect for any time of day. Let’s get started and impress your taste buds with these easy-to-make breakfast delights just like my healthy banana oat muffins recipe.

- Preheat Oven: Preheat oven to 350°F (180°C). Lightly spray a 12 cup muffin tin with nonstick oil spray.

- Whisk Eggs: In a large bowl, whisk together eggs and onion. Season with salt and pepper to taste.
*Note: Make sure to grease your muffin tin properly and use a good-quality non-stick muffin tray. If you’re unsure, use parchment paper or cupcake liners to prevent sticking.

- Fill Muffin Tins: Add the egg mixture halfway up into each tin of the greased muffin tin.

- Add Toppings: Divide the three topping combinations into four muffin cups each.
*Note: The muffins will puff up as they bake, so be sure to fill the tins only three-quarters full to prevent overflow.

- Bake Muffins: Bake for 15-20 minutes until set.

- Serve or Store: Let cool slightly, then serve.
*Note: Allow your muffins to cool for about 10 minutes before removing them. If needed, run a plastic knife or spatula around the inside walls of the muffin holes to help loosen them.

I just made these for a meeting I have this morning. My husband, who never eats breakfast, has already devoured 2 of them!
I made 12 plain with just salt and pepper, then 12 with onion and green peppers. Both smell delicious.
Thumbs up for a great recipe.
I made these today: A triumph! Absolutely delicious, super easy and low-guilt 🙂 For my 12-muffin pan, an 8-egg base was perfect (12 would have overflown, too much).
But I have two questions, please:
One: When the timer went off and I opened the oven to take the egg muffins out, they were gorgeous and puffy, expanded into a perfect golden dome. The moment they were outside the oven, they deflated and I brought to the table these sad-looking concave muffins. Is there a trick to avoid this from happening? What did I do wrong?
Two: Would it be possible to line the muffin pan with muffin/cupcakes cup? To ease the extraction of the egg muffins…
I plan on doing these over and over again. A minion thanks, f.
I personally also used 8 eggs but added 1/2 tsp of baking soda so they would get nice and puffy and lightly sprayed the muffin pan with nonstick spray. Hope that helps!
You should never feel guilty for eating. We are alive and we are meant to eat food, it is how we are designed. Enjoy! <3
Can I make these in mini muffin pans? If so, how long do I bake them for?
Yes you can! Bake them for 8-10 minutes, just keep an eye on them.
I de bake them in muffin pan and do the same time and they come out great
I loved these but 20 minutes is just too long. I took mine out at 17 minutes but I’m fairly certain they were done at about 15. Just keep an eye on them
Do you put the balsamic glaze in it or after it’s been baked?
These always turn out fantastic!!
I was just wondering how you went about freezing these. Do you use zip lock bags and a container or either? I would like to make several batches and want them to keep for a while. Thank you ahead of time.
Hi Michelle! Let the muffins cool completely, wrap each one individually in plastic wrap and pop them all in a freezer zip-lock bag or airtight container. They last for up to 3 months. To reheat, unwrap from plastic and fold them in a wet paper towel. Microwave in 15 second increments until warmed through. I hope that helps!
You can also freeze them on a cookie sheet with parchment paper and then transfer them to a large tub.
The nutrition facts do not say how many are in each serving. Is it for just one? Counting calories and wasn’t sure how many to eat in one sitting.
Hi Natalie. Yes, just for one.
It was mentioned that these could be made ahead and then microwaved. I don’t use a microwave. Is there a way to reheat them in the oven in a manner that won’t overcook them or is it just better to make them fresh? Thanks, Michelle
Hi Michelle, you can reheat them in the oven for about 10 minutes. They won’t overcook. They are definitely better tasting fresh, but reheating won’t harm them. I hope that helps!
Yes, thank you. I’ll plan on making them fresh for Christmas and reheat leftovers in the oven the next day. Happy Holidays!
The same to you Michelle!
𝕐𝔼𝕊! I don’t do microwaves myself. You can throw in, oven you reheat again or you can wrap in aluminum foil while flipping them for a couple minutes or throw them in an air fryer for 2 minutes ☺
Can you freeze these?
Yes, that is a great idea. Thanks for following along with me!! xo
Can you make them in mini muffin tins?
Absolutely! You may need to reduce cooking time.
