Feta and Spinach Frittata

This simple, flavorful feta spinach frittata recipe is a cinch to make and comes together in 20 minutes! This baked frittata recipe is perfect for a healthy weekend brunch or an easy weeknight dinner. Add my lazy Mediterranean salad for a quick and satisfying meal.

This feta spinach frittata is inspired by the flavors of a traditional spanakopita. It came together by happy accident when I made the flaky, feta, dill, and spinach-filled pastry for a large party. Instead of a typical casserole, I decided to roll the phyllo sheets into little Greek-style spring rolls for an appetizer, like the vegetarian version of my meat and feta rolls. Somehow I ran out of phyllo with plenty of filling to spare!

The next night, still drained from the party, I threw the spanakopita filling into my cast iron skillet with some eggs and popped it in the oven. Viola! A lovely, fluffy feta spinach frittata was born.

I've since played around with the spinach and feta mixture to get just the right measurements. I like to use frozen spinach as an easy way to get loads of the vitamin, protein, and mineral-packed green in my diet. A 6-ounce bag of frozen spinach is around ¾ pound of fresh! Plus, it makes this a great back-pocket pantry meal.

I also finish the frittata in the oven so there’s no fuss, no mess. No flipping or turning. It's the same technique we use in our egg white frittata with smoked salmon. Anyone can do it!

Feta Spinach Frittata Ingredients 

Making a healthy and flavorful feta spinach frittata starts with quality ingredients. Here’s what you need:

• Eggs: Use large, fresh eggs. 
• Flavor-makers: Dried oregano, dill, sweet or smoked Spanish paprika. Salt and black pepper enhance the taste. 
• Fresh herbs: Parsley and mint leaves add a fresh quality. 
• Baking powder (optional): Totally optional, but I find a small amount of baking powder helps the frittata get a nice fluffy and airy texture. 
• Frozen spinach: 6 ounces frozen chopped spinach, thawed and water wrung out
• Onion: I like the sweetness of yellow onions, but you can substitute with white or red, or a couple of shallots if you’d like. 
• Garlic: Adds that magical punchy flavor that only garlic can bring. 
• Feta: Look for blocks of feta preserved in brine, as it tends to be fresher and more flavorful than the pre-crumbled version. 
• Milk: I like whole milk for extra creaminess, but you can use whatever unsweetened and unflavored milk you’d like, including low fat or plant-based. 
• Extra virgin olive oil: Coats the pan to crisp the frittata. Use a high quality extra virgin variety–any of the olive oils from our shop would work well, but I especially love our Greek Koroneiki for this recipe. 
• Mediterranean Cucumber Tomato Salad: This easy salad is optional, but the fresh flavors complement the richness of the frittata nicely. If you’d like to make it, you’ll need tomatoes, cucumber, red onion, parsley, sumac, olive oil, and lemon juice.

How to Make this Feta Spinach Frittata

This feta spinach frittata recipe uses my go-to frittata technique: first brown the edges on the stove to create a “crust,” then finish the frittata in the oven. It makes the eggs slightly crisp on the outside with a soft, souffle-like center. And it couldn’t be easier! Here’s how you do it: 

• Get ready. Preheat your oven to 375°F. Use a cheesecloth or clean kitchen towel to wring out 6 ounces of frozen chopped spinach. Finely chop a small onion. Chop enough parsley leaves to yield 1 cup, and enough mint for 3 tablespoons. Mince 3 garlic cloves (see our how to mince garlic guide for tips).
• Season the eggs. Crack 8 eggs into a large bowl. Add 1 teaspoon of dried oregano and ½ teaspoon each of dried dill, black pepper, and paprika. Add ¼ teaspoon of baking powder (if using), season with a pinch of salt, and whisk to combine.
• Mix the remaining ingredients. Add the prepared spinach, onion, parsley, mint, and garlic, along with ¼ cup of milk. Crumble in 3 to 4 ounces of feta cheese and mix well to combine.
• Start the frittata. In a 12-inch cast iron skillet (or oven-safe skillet) over medium-high heat, heat enough olive oil to coat (about 2 tablespoons). When it’s shimmering (but before smoking), pour in the egg mixture. Give the skillet a gentle shake to allow the egg mixture to spread well. Cook for about 4 minutes or so, allowing the bottom of the eggs to settle. 
• Bake the frittata. Transfer the pan to the heated oven until the top is firm and it doesn’t jiggle when you shake the pan, about 8 minutes. 
• Serve. Remove the frittata from the oven and allow to rest for a few minutes, then slice and serve, with cucumber tomato salad on the side if you’d like. Enjoy!

Can I prepare this Frittata ahead of time?

This spinach feta frittata can be made ahead of time. There are a couple of options here for you:

• Simply do all the prep for the spinach and feta mixture. Store in the fridge in a tightly closed container. When ready, follow the recipe by adding the spinach and feta mixture into the egg mixture and bake.
• You can also make the entire spinach frittata and bake it in the oven. Once baked, let it cool completely, then slice and wrap each piece to freeze individually. You can reheat from frozen in a skillet or in your microwave for a few seconds.

What to Serve with Feta Spinach Frittata

Feta spinach frittata is a crowd-pleasing dish to serve for brunch, Mother’s Day breakfast, winter holiday breakfasts, and even as an appetizer for parties! And, honestly, I've served it for a quick dinner on a couple of busy nights.

Although this recipe is fabulous on its own, I like to serve it with my lazy Mediterranean salad or Greek Salad, and a side of my Middle Eastern skillet potatoes. If I'm serving a crowd for brunch, this frittata is a good option next to my epic Mediterranean brunch board.

This recipe also freezes well, so it’s a good thing to make for a friend or family member who might need a little extra TLC. Once it’s baked, let it cool completely, then slice and wrap each piece to freeze individually. Simply reheat from frozen in a skillet or in your microwave for a few minutes.
