Why you’ll love them

These cute spinach egg muffins are a little bit special. Here’s a summary of what you’ll love.

  • So quick and easy. They’re a little similar to my famous crustless quiche recipe, zucchini slice and baked vegetable frittata, but arguably even easier since nothing has to be pre-cooked. In less than 30 minutes, you’ll have 12 very cute, tasty and fluffy mini frittatas that the whole family will love.
  • Just a few simple pantry and fridge ingredients. You’ll need just 4 eggs to make 12 spinach egg muffins, making this an economical recipe, too!
  • Delicious taste and texture! Added flour makes the texture of these firmer than classic egg muffins, making them easy to pack into lunch boxes or for picnics. They’re also slightly crisp on the outside – mmm! More ‘secret’ ingredients including pesto and mustard make sure they pack a punch in flavor, despite the few ingredients.
  • Great for making ahead. These keep well in the fridge for a few days. Enjoy them cold or reheat in your microwave, oven or air fryer. Alternatively, you can freeze them in baking paper, then grab and go for an easy breakfast or other pack-up meal.

About the ingredients

All the ingredients for spinach egg muffins labelled including eggs, milk, cheese, flour, tomatoes, pesto, salt and pepper, mustard, garlic and spinach.

Tomatoes: I chop them into small pieces. You could also use cherry tomatoes.

Garlic: I like the extra hit of flavor that the garlic adds to this recipe. I don’t use a lot, but feel free to add more or skip it all together if you prefer (there’s more garlic in the pesto).

Spinach: I prefer store-bought fresh baby spinach for the convenience (no chopping!). Feel free to use frozen spinach if that’s what you have, but make sure you squeeze out as much water as you can first.

Pesto: This really makes the frittata extra tasty! Regular pesto or tomato pesto are both great. Use nut-free pesto if allergies are a concern.

Cheese: I usually go for a mixture of at least two or three cheeses – usually chosen from feta, cheddar, and parmesan. Other cheeses such as gruyere, ricotta cheese, goat cheese or any other cheese are great choices as well.

Flour: I use self-raising (AKA self-rising) flour for this recipe because it makes the texture of the frittatas firmer (perfect for lunch boxes, picnics and finger food for little ones!). If you don’t have any, use plain/all purpose flour mixed with a teaspoon of baking powder.

For those of you in the USA, this recipe will also work well with Bisquick, instead of flour.

Fresh Milk: Use whatever you have on hand – whole milk or reduced fat (semi-skimmed/high-low/2%). For a richer result, you could also replace some of the milk with cream, but really there’s no need. Milk works perfectly for this recipe and it keeps the frittata light and economical.

Eggs: You only need 4 eggs for this recipe (bonus!).

Mustard: My top choice is a wholegrain mustard, but Dijon mustard is another good choice. If you only have mustard from a squeezy bottle, use that!

Salt and pepper: I’ve suggested an amount, but you can adjust according to taste.

How to make spinach egg muffins

Step 1. Wilt the spinach. There are two easy ways to wilt the spinach for this recipe: using a pan or boiling water. For the pan method, add the spinach to a non-stick pan over low heat for about 1-2 minutes. It will wilt quickly, so keep an eye on it and stir occasionally. Don’t worry, it won’t take long!

The other way is to pile the spinach into a colander and carefully pour boiling water over it. This will wilt the leaves in a flash. Just remember to give the spinach a quick rinse with cold water afterwards to cool it down.

No matter which method you choose, you need to squeeze out as much water as possible. I usually use my hands, but you could squeeze it in a clean tea towel.

Step 2. Prepare the egg and milk mixture. Blend some of the milk into the flour until there are no lumps. Then add the eggs and the rest of the milk.

Step 3. Stir in the fillings. Add the spinach, garlic, pesto, cheese, mustard, salt and pepper and stir until combined.

Step 4. Grease the muffin tin and pour the egg mixture equally between the muffin holes. Scatter the chopped tomato all over the top (I love the little bit of color this adds!).

Step 5. Bake for around 10-15 minutes at 375F/190C, or until the muffins are puffed up and golden without any raw egg.

Helen’s Top Tips

  • Spray the muffin holes generously with oil to stop them sticking. It doesn’t matter if a little of the mixture still sticks.
  • Only fill the muffin holes about 2/3 to 3/4 full with mixture. The tomatoes will add a little more volume.
  • If you have one, use a rubber spatula to run all the way around each baked egg muffin and underneath it to get it out of the muffin hole cleanly.
  • These are great popped into lunch boxes straight from the freezer. By lunch time, they’ll have defrosted. Either enjoy cold or reheat covered for 30 seconds in a microwave. After this, check and microwave for 15 or 20 seconds longer or until piping hot again. In the oven, try around 15 minutes or until the muffins are heated through or put them in the air fryer for about 6 minutes at 320F/160C. You can also reheat them straight from frozen. Add a couple of minutes in the air fryer, or 5 to 10 minutes longer in the oven.

Ways to vary the recipe

Here are some ways to customize your muffins to make them your own:

  • Leftover Vegetables: Use up leftover roasted vegetables like broccoli, peppers, zucchini, or even sweet potatoes. Dice them up and toss them in with the spinach.
  • Cheese Variations: Easily swap the feta for shredded mozzarella or Monterey Jack. You could also add spoonfuls of ricotta cheese. Goat cheese adds a nice tangy twist, too.
  • Cooked meat: Crumbled bacon (try air-fried!), sausage, or diced ham are great with these egg spinach muffins.
  • More savory additions: Sautéed mushrooms or caramelized onions (for a touch of sweetness) add a lot of flavor.
  • Make spicy muffins: Add a pinch of red pepper flakes or a sprinkle of cayenne pepper for a spicy kick.
  • Chopped fresh herbs: Eggs are great with fresh parsley, chives, or even oregano.

  1. I am wanting to make these this weekend to take to a christmas street party. Am I able to make these in the mini muffin tins as I want them to be bite size.

    1. Hello Jenny! Aw, a Christmas street party sounds wonderful! You can definitely make mini versions of these. They’ll probably be done in a bit less time. I’d check after about 8 minutes initially and see how you go from there. Good luck and enjoy the party! 🙂

  2. 5 stars
    I can see how these would make a great breakfast idea. Easy to prepare and colorful tasty as well. Loaded with veggies!

  3. Hi there, just wondering if I could make this in a large version?

    In a quiche pan or pie dish?

    Thank you!

    1. Hi Michelle! I don’t see why not! This way, I guess it would be like a frittata. To be honest though I can’t say confidently how long you should cook it for as I haven’t tried the recipe this way yet. I’d guess it would be longer than 12 minutes though. Based on other frittata recipes online, however, I’d try 20 minutes at 350F, then check if it’s cooked. Good luck!

  4. Je crois que je préfère tes frittatas pour le petit déjeuner a un croissante ! Elles sont l’air tellement bonnes ! J’imagine bien mangé celle-ci avec mon café demain matin !
