Frittatas are a weeknight go-to in our home because they’re easy to make and allows us to use ingredients we already have on hand.

This sun dried tomato frittata is similar to our potato frittata in that we include potatoes, Pecorino Romano, and eggs as the base.

But the addition of sun dried tomatoes, fresh baby spinach, and fresh mozzarella adds wonderful flavors and textures!

Pair this fresh mozzarella and spinach frittata with a simple green salad, a bowl of soup, or a chunk of olive bread.

Recipe Ingredients

All ingredients for this recipe are shown in the pic below and special notes are made in this bulleted list to assist you.

Ingredients shown: eggs, olive oil, milk, potatoes, onion, sun-dried tomatoes, spinach, Pecorino Romano, and sliced fresh mozzarella cheese.
  • Eggs. The main ingredient in this sun dried tomato frittata!
  • Sun dried tomatoes. I am using the ones from a jar in oil that I drain and chop.
  • Spinach. Use fresh baby spinach for best results.
  • Cheese. I use a combination of Pecorino Romano and fresh mozzarella. You can substitute parmesan for Pecorino if you prefer.
  • Potatoes. Yukon golds and red potatoes work well but you could also use russets if that’s what’s available to you.

Top tips

  • Squeeze the spinach. Be sure to squeeze all excess moisture from the spinach to prevent a watery frittata!
  • Cast iron pan. I love using the cast iron pan for frittatas because I can use it on the stovetop and place it right in the oven. I do take an extra step and place the pan on a baking sheet to catch any overflow from the pan but that’s not really necessary.
  • Additions. Feel free to add to this sun dried tomato frittata! Oil-cured olives would be great as would a topping of fresh pesto.
