Why you’ll love them

I’m convinced that whoever invented egg cups is a genius. They’re easy to make ahead, you can take them on the go, and they’re a tasty and hassle-free breakfast with plenty of protein. These savory little gems will make you look forward to eating them in the morning.

If you’ve never had egg muffins before, they’re basically like mini frittatas that you bake in a muffin tin. The egg is firm yet fluffy, and you can add in all sorts of other ingredients. In my version we have spinach and mushrooms, so it’s a simple way to eat veggies.

Ingredients for them

  • Eggs – we’re using six whole eggs here for 12 muffins
  • Skim milk – for moisture
  • Italian seasoning – I always keep a jar in my pantry of this flavorful dried herb blend
  • Garlic powder – to add a little savory depth of flavor
  • Spinach – fresh spinach adds some nutritious goodness
  • Mushrooms – I used white button, but your favorite variety is great

How to make egg muffins

This is an overview, and full ingredients & instructions are in the recipe card below.

  • Preheat your oven to 350F. Grease the muffin tin generously. I use cooking spray to make it easier.
  • Whisk the eggs, milk, Italian seasoning, garlic powder, and salt & pepper in a mixing bowl. I like using a simple balloon whisk. Stir in the chopped spinach and mushrooms.
  • Spoon the mixture evenly into the muffin tray, bake, and enjoy!

Tips for success

  • Make sure the muffin tin is really well greased prior to adding the egg mixture. These baked egg cups should slide right out. Cooking spray works great to keep them from sticking, so it saves you clean-up later on!
  • The mixture won’t fill each cavity in the muffin tin completely, which is because they expand.
  • To make sure they’re done, simply slide a toothpick into the middle of one of the egg muffins. If it comes out clean, they’re fully cooked.

Substitutions and variations

  • This is meant to be super quick to prep, but you’re welcome to sauté the mushrooms before adding them in.
  • There are endless variations for what flavor combos you can use! Here are some of our favorites for changing it up: fresh tomato and mozzarella, ham and cheddar, & parmesan and red bell peppers.
  • Love bacon? Make this simple oven bacon recipe, and then crumble it into the egg mixture!

Leftovers and storage

  • These egg muffins will keep in the fridge in a tightly sealed container for 4-5 days.
  • You can also freeze them for up to 3 months. We like to store them wrapped up individually in plastic wrap for convenience and then placed in a larger covered container.
  • To warm these up, simply pop them in the microwave on a sheet of paper towel for about 30 seconds or until warmed through. Microwaves do differ, so timing could vary.

  1. These are fabulous Natasha. The only problem was I made them mid-morning and only three survived for next days breakfast!

  2. Hi Natasha,
    These look great! Quick question is this the same recipe if I use a mini muffin tray, or do I need to change it?
    Also may I saute the mushrooms beforehand, and possibly the spinach too?
    Thank you,
    Maggie

    1. Hi Maggie! Sure, sautéing will definitely work. A mini muffin tray should be fine too, but may need slightly less cooking time. Hope you enjoy the recipe! ❤️

    I am a fan of spinach and mushroom in eggs and these are great. Just an FYI, I can’t have dairy so I added a 1/4 cup of soda water for nice puffy muffins. A good alternative if you need/want to cut the milk. Looking forward to tomorrow’s breakfast!

    Love these! Could I possibly add cooked ground turkey to this as well? If added would the egg muffins require a new cook time or oven temp?

    1. Hi Kaitlyn! I think that adding cooked turkey should work just fine. I’d keep the temp and cooking time the same to start with.

    These look delicious. I didn’t see the nutrition info except the calorie count. How many carbs does the skim milk add?

    1. Hi, Lynn! I didn’t work out the full nutritional info, sorry about that. I don’t provide it for most of my recipes for various reasons. If you have a nutritional calculator you trust, try plugging the values in and see what it comes up with.
