Why I Love This Zucchini and Tomato Summer Frittata

The tomatoes and the zucchini I had in my fridge inspired this dish. Frittatas are really easy to put together, and this is the first one I've made in a cast-iron skillet in a long long time.

Don't get me wrong, making a frittata in a rice cooker is so awesome and easy, but using a cast iron skillet means you can sauté your vegetables in the same pan you cook the frittata in, which is extra great.

This recipe is really easy and delicious, and only about $4.40 for 4-6 servings! Frittatas are great for breakfast, lunch, or dinner, and I'm super excited about 3 days of easy breakfasts for us this week.

Ingredients to Make a Summer Vegetable Frittata

I've made a lot of frittatas in my life, and despite all the various (often Paleo) iterations, I now know that my favorite addition is CHEESE. The feta in this dish is salty and tangy and is perfect for summer flavors.

I think this particular frittata would be great with Parmesan or goat cheese also.

The remaining ingredients include:

Onion and garlic
Zucchini
Tomato
Eggs
Milk
Seasonings

Optional Additions

We've also been successfully growing four little basil plants on our windowsill despite my black thumb, so I tossed a little basil on top just for kicks.

I bought a little four-pack of basil plants for around $3-5 at the farmer's market, and we've already stripped them bare once for pesto, plus we've been pulling basil for pasta and pizza and various other dishes for the last two weeks. I love it!

How To Make This Frittata Recipe

It's pretty simple to whip up this zucchini and tomato frittata and that's exactly the way I like it! First, you're going to prepare your vegetables by chopping everything up and mincing the garlic.

Then you'll saute the onion in the cast iron skillet and then add all of the vegetables. While they cook, you'll whisk the eggs, milk, and seasonings, and then add the mixture to the pan to cook through.

Top with feta, bake for 30-35 minutes, and voila! It's time to enjoy!

FAQ

What’s the difference between a frittata and an omelet?

They're both cooked and served differently! While an omelet is cooked on high heat and served immediately, a frittata is cooked over a lower heat for a longer period of time. Omelets are served hot and frittatas are often served cooled, which makes them a great dish for a gathering!

How do you keep a frittata fluffy?

It's all about the milk! You can use plant-based milk if you'd like, but without milk altogether the frittata will come out rather flat. Which is also delicious, just not fluffy.

What makes frittata rise?

The eggs expanding in the baking process is what makes a frittata fluff up, so be sure to not overbeat your eggs.

Variations and Dietary Modifications

Add mushrooms for a more savory umami flavor.
You can add potatoes to make it a little more filling.
If you eat meat, add sausage!
Swap out the tomato and/or zucchini based on the veggies you have on hand.

Vegetarian: Yep!
Paleo: Sorry, but you'll have to skip the cheese! Maybe you could replace it with sausage?
