Pin ItEasy Egg Muffins (Healthy, Make-Ahead Breakfast!)
I always have a batch of these egg muffins in my fridge, and they have truly saved my mornings more times than I can count.
Life gets busy, and breakfast is usually the first thing to get skipped, but having these ready to go makes it so much easier to start the day on a good note. I can grab one as I’m heading out the door, warm it up in seconds, and actually feel full and energized until lunch.
I’ve tested this recipe over and over, and this combination is my favorite. The white cheddar gets perfectly melty, the tomatoes add a fresh pop of flavor, and the spinach makes me feel like I’m doing something good for myself.
They’re simple, satisfying, and exactly the kind of recipe you’ll come back to every week. Plus, they are easy to customize. My boys love them with bacon or sausage and sometimes I mix up the veggies or cheese, depending on what is in my fridge. And bonus? They freeze well too so they are perfect for meal prep!
If you’re looking for a healthy breakfast you can make ahead, these egg muffins are it.
Ingredients (with Helpful Tips)
- Eggs – Use large eggs and whisk really well so the muffins bake up light and fluffy
- Milk – Just a little helps keep the texture soft and tender
- Grape tomatoes – Chop them so you get a little in every bite; they add freshness and juiciness
- Spinach – Chop it finely; if it feels watery, give it a quick sauté or pat dry
- White cheddar cheese – Sharp white cheddar adds great flavor; shred your own for best melting
- Green onions – Add a mild onion flavor without being overpowering
- Garlic powder – Easy way to boost flavor without extra prep
- Salt & black pepper – Don’t skip—eggs need seasoning!
- Optional toppings – Avocado, salsa, herbs, or hot sauce take them to the next level
Tips for the BEST Egg Muffins
- Grease the pan generously – This is key so the eggs don’t stick. You can also use a silicone muffin pan.
- Whisk until slightly frothy – This helps create a lighter texture.
- Don’t skip seasoning – Eggs need enough salt and pepper to taste their best.
- Divide evenly – Ensures even baking.
- Don’t overbake – Remove when just set; they’ll continue cooking slightly.
- Let them cool before removing – About 5 minutes makes them easier to release.
How to Store & Reheat
These are perfect for meal prep because they reheat beautifully and keep their texture.
To Store: Let the muffins cool completely and store in an airtight container in the refrigerator for up to 4 days.
To Freeze: Freeze in a single layer until solid, then transfer to a freezer-safe bag or container and freeze for up to 2 months.
To Reheat: Microwave for 30–60 seconds or warm in a 350°F oven until heated through
Egg Muffins
Ingredients
- 12 large eggs
- 1/4 cup milk
- 1 cup chopped grape tomatoes
- 1 cup chopped spinach
- 3/4 cup shredded white cheddar cheese, divided
- 1/4 cup chopped green onions
- 1/2 teaspoon garlic powder
- Kosher salt and black pepper, to taste
- For serving: avocado, salsa, herbs, hot sauce, optional
Instructions
- Preheat the oven to 350 degrees F. Grease a muffin tin generously with nonstick cooking spray. Set aside.
- Crack the eggs into a large bowl and whisk until combined. Whisk in the milk. Add the tomatoes, spinach, cheese, green onions, and garlic powder. Gently stir with a spatula. Season with salt and black pepper, to taste.
- Pour the egg mixture evenly into the greased muffin cups. Sprinkle remaining ¼ cup of cheese on top of the egg muffins.
- Bake for 20-25 minutes or until the eggs are cooked. Remove from the oven and let cool for 5 minutes in a pan. Use a knife to loosen the muffins from the pan. Serve immediately with avocado, salsa, herbs, and/or hot sauce, if desired.
Notes
- Grease the pan well: Eggs can stick easily, so be generous with nonstick spray or use a silicone muffin pan for easy removal.
- Whisk thoroughly: Whisk the eggs until fully combined and slightly frothy for the best fluffy texture.
- Watch the moisture: If your spinach or tomatoes are very juicy, pat them dry or sauté briefly to prevent watery egg muffins.
- Don’t overbake: Remove from the oven when the centers are just set. Overbaking can make the eggs rubbery.
- Let them cool slightly: Let the muffins sit for about 5 minutes before removing, they’ll release more easily.
- Make them your own: Swap in your favorite veggies, cheeses, or cooked meats. This recipe is very flexible!
- Storage tip: Store in the fridge for up to 4 days or freeze for up to 2 months for easy meal prep.

I love almost all the recipes on this site, but this was a miss. The flavors were off– I think it called for too much spinach, but I’m not sure the components worked together overall. I greased the muffin tin very well but it was a nightmare to clean. The freezability and small portions of this recipe were so appealing. Too bad! We love many others– the rigatoni with sausage is one of my boys’ most requested recipes 🙂
I made half the batch as I didn’t have many eggs and these came out great! I sprinkled some Parmesan cheese on top as well. I had a lot of trouble getting them out of the muffin tin despite a heavy coating of nonstick spray. Has anyone tried using those silicone muffin cups?
Yes, the silicon muffin cups are awesome!!
They are available from Amazon.
Silicon cups can be used for muffins, cupcakes, crustless quiche, etc.
You can spray the silicon cups with Pam, but it wasn’t necessary when I made muffins.
Also a muffin tin is not required. The silicon cups stand up without being in a muffin pan.
Place the silicon cups directly on a baking sheet and place in the oven.
Silicon cups are microwave, freezer, and oven safe (up to 445 degrees).
Let the silicon cups stand to cool for 5 minutes after cooking. Muffins will pop out.
Cleaning the silicon cups is easy. Just place them in wash soapy water.
Silicon cups cans be turned inside out to wash. Rub with fingers.
When I cooked egg muffins, there was no residue left in the silicon cups.
I just made these and yes, it was a pain getting these out of my well greased non-stick muffin tin so I just ordered a silicone one from Amazon. I did modify the recipe a bit: I used red onion instead of green and I sautéed them first before adding to mixture. I also use chard from my garden instead of spinach and again, sautéed it first. I made these for my rancher husband so I added in breakfast sausage that I precooked and crumbled in. He takes two every morning and loves them. Super great time saver during harvest. Another winner Maria, thanks!
Quick to come together and tasty! Such a great breakfast option!
Glad you enjoyed the egg muffins!
Can the paper cupcake liners be used with these? I make breakfast occasionally for a local group that feeds homeless folks (sometimes 100+). This looks like a nice option to casseroles but I don’t have the time or energy to wash a muffin tin after every use.
Yes, but spray them first so they don’t stick.
These look delish, but I’m nervous to make these after reading the comments of people who had a really difficult time getting the egg muffins out of the tin, even after greasing. What is the best trick? Does greasing with butter work better than spraying with oil?
I haven’t had a problem. Use a good non-stick muffin pan and grease well! I always use avocado oil spray and they are fine!
