Spinach Frittata

Tested & Perfected Recipes

Stuffed with baby spinach and two kinds of cheese, this spinach frittata makes a lovely brunch, lunch, or light dinner.

Filled with heaps of baby spinach and two kinds of cheese, this spinach frittata tastes nutritious and rich, all at the same time. It’s silkier and more quiche-like than most frittatas, which are usually just glorified omelets with the fillings mixed in rather than stuffed inside. The key is adding heavy cream and lots of cheese to the egg mixture. It’s also important to bake the frittata in a low-temperature oven (as opposed to the traditional stovetop-to-broiler method), so the eggs cook gently into a custard without scrambling.

This frittata can be served for brunch, lunch, or a light dinner – and since it’s good warm or at room temperature, leftovers can be packed for lunch or taken on a picnic.

Reviews & Comments

  • The frittata is really good; however, I did have an issue with the cooking time. I had to let it bake for 30 minutes and still there were some areas that were not fully cooked so I turn on the broil for 3 minutes and that took care of the issue. Thank you Jen.

  • I have no nonstick pans, but I have the All-Clad D3 10 inch stainless steel. Can I make the frittata in this pan? Thank you. Love your recipes.

    • Unfortunately, I think it would stick so I wouldn’t recommend it — sorry!

    • I just bake mine at 350 degrees in a large, glass, buttered pie plate for about 40-45 minutes. Saute the spinach first (I don’t use onions) and add everything to a bowl and mix. Turns out great!

  • Another winner—especially for spinach lovers! Be careful though not to overbake (I did slightly and the bottom was more browned than ideal)–but recipe was fantastic and next time I’ll be more careful to keep to only 20 minutes in the low oven!

  • I love all of the other frittata & quiche recipes but something just seemed off on this one. Perhaps too much spinach.

  • Hi there, for the cheeses, are you using a liquid measuring cup or weight in ounces? For example, should I fill a 3/4 cup with shredded Cheddar cheese, or measure out 3 ounces (package says 1/4 cup = 1 ounce). Sorry if I’m overthinking this!

    • Hi TJ, You’ll want to fill dry measuring cups (so 1/2 cup + 1/4 cup for the Cheddar). Hope that clarifies and that you enjoy!

    • Sure, I think that would work – I’d suggest a 9-inch square pan or 9-inch deep dish pie pan. Please LMK how it turns out!

  • This was easy and delicious. It’s too much for the two of us but reheats well. I made it exactly as specified but can see that it is quite adaptable. I really appreciate the metric version, since volume measurements of cheese depend a lot on how it’s grated. One minor correction – the metric version has the oven temp as 165 F, not 165 C. Believe me, it doesn’t work!

  • I’ve made this three times now, the second time, a doubled recipe in a larger pan. Each time I used frozen spinach and red onion instead of shallots – the third time three red onions (well-cooked) because I thought the extra onion would taste good. I matched the cheese the first couple of times but used haloumi instead of cheddar the third time. I used 30% cream the first two times and a mixture of milk and yogurt the third time. Each time it came out perfectly! Thank you for a great recipe, Jenn, that is very conducive to modification. I notice you have nutmeg in your spinach quiche recipe so next time I make the frittata I’ll also add some nutmeg. This is the only recipe of yours I’ve made so far but as I can see others look so good I’ll be making more.
