Why we love this recipe
This recipe for spinach feta oven frittata came about from my love affair with my cast iron skillet.
From casseroles to cobblers, and from bacon to all kinds of eggs, this skillet is one of my favorite kitchen buddies, and as your grandma could probably tell you, the more you use it, the more seasoned it gets, and the better it cooks.
Because of the whole cast iron thing, it can go from stovetop to oven, and it delivers a steady, serious heat that is perfect for things like frittatas full of cheese and spinach deliciousness.
So grab your own cast iron skillet (or whatever oven-safe skillet you have – that will work too) and let’s make it!
See the recipe card for full information on ingredients and quantities and nutritional information.
Here’s how to make this recipe
You start by sautéing up some baby spinach, which I particularly love because it usually comes pre-washed and with no chopping needed because of its cute baby spinach size leaves.
Once it is nice and wilted, transfer it to your oven-safe skillet, pour some beaten eggs on top, sprinkle on some crumbled feta cheese, shake on a little salt and pepper and pop it in the oven. About 30 minutes later you have a skillet full of THIS.
Tender, warm, cheesy deliciousness!

These are some of my favorite kitchen tools! These are Amazon affiliate links, which means I get a little something if you buy through my links at no extra cost to you. (Which helps pay for all that bacon I keep buying! 😄) And I only share things I use and love. I’m so grateful for your support!
- Cast Iron Skillet: We love this sturdy skillet for so many things (especially for making a chocolate chip cookie in a skillet!)
- Measuring Spoons: These are our favorites because they come apart so you can use just the spoon you want.
- Mixing Bowls: These dishwasher safe bowls have a handy handle!
I like to scatter a generous amount of oregano on top because it goes so perfectly with the feta cheese flavor. Let it cool for about five minutes, then cut it up into wedges and serve! Almost too good and easy to be true, right? BUT IT IS.
Oh, and got extra feta? Use it in this scrumptious Greek Grain Salad!

It was delicious and so easy! I added a few sundried tomatoes. I would like to make a double batch for more servings. Do you think it would work to double it in a 9×13 pan?
Hi Laurie! Yes, I think that would work just fine! It might need another 5-10 minutes of cooking time, but check it after the regular timing and see if it looks set. Meantime, sun-dried tomatoes make everything more delicious – great idea!

I admit it. I’m a recipe stalker. I like to look at recipes, perhaps several recipes that produce similar results. Then, I gravitate to one to use as the base, then make modifications based on other recipes’ suggestions.
For a 10″ inch skillet, the proportions here are perfect. (well, I added 2 eggs and two tablespoons (ish – eyeballled it) of milk, but I like a taller fritatta…just my preference
I also started the spinach skillet with about half a medium red onion, sauteed for about 3 – 4 minutes, then added two garlic cloves, pounded with a chef’s knife, peeled and roughly minced. Stir briefly and add the spinach. Here, I also added about 1/2 – 1 tsp of both oregano and basil right on top of the spinach. Let it cook until wilted and nearly dry.
Followed your procedure from there on out. It is now baking. Smells amazing!
Hi Stephen! And that’s a dedicated approach to recipes and one that I bet results in some scrumptious dinners! Hope that frittata turned out as amazing as it smelled! :)
Doreen says
I need/want to make this for about 25 people so can’t use a cast iron skillet. Any suggestions?? Glass lagasana pan can’t do cook top can it? If no suggestions any other egg recipes ? No meat, no bread..please I’m desperate
Hi Doreen! You can absolutely make this for a crowd – you will want to triple or quadruple the ingredients, so a lasagna pan will be perfect (or you can make it in two pans, depending on how big they are). Cook the spinach the way the recipes says on the stovetop – maybe in two batches – and then use the pan instead of the skillet for the rest of the recipe so it will fit all your ingredients. You will probably have to extend the baking time a little bit since the pan won’t conduct as much heat as the skillet – I would start checking it after 30 minutes, but plan on as much as 45 – you want the eggs to be set. I will email you with a couple more egg dish ideas too! :)

This was extremely easy but still a great way to use my cast iron as well as get some veg & protein in with my cheese habit. I was worried about getting the egg mixture out of my pan but it was 10x better than when I’ve tried to make scrambled eggs. Pop some extra veg & seasoning in as you like–there’s room for the goodness!
Thanks Kevin! And there’s definitely always room for extra veggies and spices! :)
Vicki Thornton says
Could you sauté the spinach in the cast iron skillet?
You could – just make sure if there is liquid in the pan after the spinach is wilted (sometimes spinach can be juicy!) that you drain it out. :)
Kim says
I tried this recipe out last week! So tasty, great breakfast meal!
I’m so glad! Oven Frittatas are one of my favorites. :)
Theresa M. says
Yum! Love the spinach and feta combo. Have to have meat with our meals, though, so will throw some cooked sausage in there for mine. Have you tried making pizza yet in your cast iron skillet? So, so very good! You can use the cast iron skillet on your grill so no need to crank the oven up in the house!

oh, i do love a frittata, and judging by your related posts, so do you! :)
i actually have never baked one in my cast-iron skillet, but that’s definitely worth a go!

Kate, I am loving this love affair that you’re having with your cast iron. Don’t worry, I won’t tell the Southern Husband. ;) This frittata looks just perfect! Can’t wait to see what you cook up next. Have a great week, my friend!
Mir says
Spinach and feta is one of my favorite combos. And cast-iron skillets are the best. This looks amazing!
Gayle @ Pumpkin 'N Spice says
I actually just made a similar frittata a few weeks ago, and I’ve been hooked on the flavors! Spinach and feta is one of my favorite combos, and I love eating it for breakfast! Looks delicious, Kate!
Anu - My Ginger Garlic Kitchen says
I have cast iron pan, but I don’t know why I don’t use that often but that needs to be changed now. Spinach and feta is a great combo, so I am gonna make this delicious looking frittata very soon.
Karen Nelson says
Glad for this post Kate! I have gotten off the frittata wagon (there is one right?!) for some reason for supper!
I agree .. So simple yet beautiful. I might toss some red bell pepper with the spinach as I am being well supplied by a friend.
On the cast iron note… I use my moms all the time. It has to be ummm…50 years old at least. ( funny I remember it when I’m not that old!..just turned 60)
It has seen eggs, chicken, chicken fried steak, etc. as she was a southern gal. You really can’t beat it.
Sooo thanks for getting me to ride back on the wagon and btw… Have a Happy 4th????????❤️
As always… Big Hugs!

Adina says
I have the same feelings for my cast iron skillet, I have only for about 1 year now, but I use it all the time. This spinach frittata is a great opportunity to use it again, so simple but so tasty, I am sure, spinach and feta make a great combo!
