Spinach & Feta Muffins Recipe!

Spinach and Feta Muffins or "cups" are a low-carb, keto-friendly version of fancy Greek spinach pie and they start with frozen spinach! It's hard to believe they have just 3 ingredients!

If you want to eat more green, then these keto spinach muffins are the way to go! We tweaked our popular Cauliflower Muffins to come up with this healthy recipe that makes this vegetable something any kid or adult would love for an appetizer, snack, or even breakfast! 

That's the thinking behind all our Healthy Veggie Egg Muffins. They're mostly vegetables with an egg and cheese gluing everything together. They could also be described as a "bite" or a "tot" because there's no flour at all.

Ingredients and Variations

Here's what you'll need to make the recipe. And, I'll swear by it. You only need 3 ingredients! 

• Spinach - frozen, chopped spinach that has been defrosted. In the next section, we talk about an easy, no-mess process for squeezing out the excess water.
  • Frozen spinach comes in lots of different packaging sizes. We used a 15-ounce package (steam-in-the-bag product) that yielded about 1 ½ cups of packed spinach. 
  • If you use a slightly larger bag, then you may want to add another egg.
  • If you use a 10-ounce bag, then cut back to about ⅓ cup of feta cheese.
• Feta Cheese - crumbled, full- or low-fat, depending upon your preference. Use a four-ounce container.
• Egg - One large or extra-large egg, which helps holds the spinach muffin together.
  • Use 2 eggs for a more "eggy" cup. And, there is nothing wrong with that!

Additional ingredients you may want to add:

• Salt - add a pinch if desired. We did not need it. 
• Garlic - couldn't hurt!
• Finely minced onion - don't add more than ¼ cup.

How to squeeze water out of frozen spinach

This tip will have you making Spinach Egg Muffins ALL THE TIME!

The main ingredient in this recipe is defrosted, chopped spinach, with excess water REMOVED. If you're like me, then you're thinking messy, messy, messy!

Here's how to easily remove it with minimal mess:

• Place an unopened package of frozen spinach in a bowl in the refrigerator, overnight. Trust me, the closed package will leak!
• The next day, pour spinach into a strainer and then press down on top of the spinach with another bowl or your hands to release the liquid into the sink or a plate.
  • Very little spinach should escape the strainer, but you can always pick it up off the plate if it does.
  • If necessary, blot it further with a paper towel. However, I did not need to do this.

Expert Tips

• Once water is removed from spinach it will be very compact. Use a fork to really break it up.
• Crumble any large pieces of feta cheese. The smaller the better!
• Mix really well so the egg and cheese is fully incorporated. These two ingredients help the muffins stick together. 
• Use a 1 Tablespoon quick-release scoop to portion the spinach mixture into the muffin tin wells.
• Once the mixture is in the muffin tin, press down on it with a spoon or your fingers to compress it.
• Allow the spinach and feta egg muffins to rest in the pan for 5 minutes after they've been removed from the oven before gently removing from them from the pan. They're delicate. But, they should be firm enough to pick up and eat with your fingers!

FAQ

Storage and Re-heating 

Refrigerator: Store in the refrigerator for up to 3 days. For best results, reheat in a toaster oven for 2-3 minutes until warmed. 

Freezer: Place in a freezer bag in a single layer until frozen solid. After that, move them around as needed. But, you'll still need to be careful because they are delicate and spinach will chip away. Reheat from frozen for about 10 minutes or until warmed through.
