You'll ❤️ This Caprese Frittata Recipe

Caprese salad has always been one of my favorite dishes. So much so that I created several versions. LOL! Make sure to try this Cherry Tomato Caprese, and this Grilled Eggplant Caprese Salad. I know you'll love them. The frittata makes great leftovers!

Is it a Frittata or a Quiche?

It's both! This recipe could either be called a frittata or a crustless quiche. Both are made with eggs, the biggest difference is that frittatas ingredients are typically cooked on the stovetop and then moved to the oven for baking.

Quiches, on the other hand, are usually only baked. Ingredients are prepared beforehand, mixed together in a bowl and then poured into a baking dish, then sent into the oven.

Of course, there are always variances in both methods, but these are typical examples.

Frittata Is Easy

Don't be intimidated by the list of ingredients. It is all easily prepared and all gets cooked in the same pan. The hardest part is chopping the onion (which isn't too hard)!

A Healthy Crustless Quiche

Frittatas and quiches use a lot of eggs and fresh ingredients which make them healthy. Eggs are nutrient-packed wonders. This version of a crustless quiche/frittata is made even healthier as it is low carb, has no sugar added, and is keto-friendly.

Crustless Quiche - Keto

Whether you call it crustless quiche or frittata, this recipe is perfect if you're following a keto diet.

It tastes great

I'm a huge fan of frittatas because they are so delicious. I love the flavors of this one. Caprese salad is one of my favorite things to make during the summer when my roma tomatoes are ripening all at once.

This year we have an abundance of cherry tomatoes and eggs (from our 17 chickens). It was actually my husband's idea for me to make a caprese salad frittata! Good idea, honey!

It's a one-pan dish

Other than whisking your eggs and milk in a bowl, this is a one-pan that goes from stovetop to oven quickly! It also gives me an excuse to use my cast iron skillet - which is my favorite pan!

FAQ's

Who invented caprese?

The Italians invented caprese in the early 1900's - in Capri. Capri a charming island Southwest of Sorrento in Western Italy. See it on the map

Traditionally served as a salad (Insalata Caprese), with alternating slices of tomato, fresh mozzarella, basil, salt, pepper, and drizzle with olive oil (and many times balsamic vinegar). Here's a great recipe for Caprese Salad!

I love that not only does this taste fabulous, the colors resemble the Italian flag...so pretty!

Thank you, Italy!

What goes with Caprese?

Caprese is an italian dish so anything italian would go well. If you are making Caprese Frittata it is a really a meal in one, but you could serve it with a nice caesar salad.
 
If you are making caprese salad, you would want to serve with protein like a grilled chicken or baked chicken.
 

Why is my frittata watery?

Frittata can become watery if low fat milk is used, or your fresh ingredients, such as spinach and tomatoes have too much water.

If using more that a couple cups of spinach it is advisable to squeeze the moisture from the spinach. You should also use tomatoes with less moisture such as roma tomatoes or cherry tomatoes. Do not use more than 1 cup of tomatoes.

How do you freeze a frittata?

Pre-slice the frittata into individual slices. Freeze in individual freezer safe containers, one larger container, or freezer bags with pieces separated by parchment paper.

Thaw and re-heat in microwave.

The frittata is easier to reheat and handle if in smaller portions.

| Is a frittata the same as a crustless quiche?

Yes and no. They are similar in that neither has a crust, they are made with eggs and milk as a base, but they are different slightly in cooking method.

The frittata ingredients are cooked partially on the stove (in one pan), then that pan is put into the oven to complete baking.

A quiche is usually made by baking the whole thing. Onions, and certain other ingredients, need to be sauted in a separate pan before adding to the quiche mixture.

What is crustless quiche called?

Usually it's called a frittata.

Can you use fat free half and half in Quiche?

You can use fat free half and half, but it can result in a more watery texture. Be careful if you are adding ingredients with a lot of moisture.

How long does crustless quiche last?

Crustless quiche or frittata will last 3 to 4 days in the refrigerator.

Hey there, I'm Kori.

I’m a culinary school trained chef specializing in holistic nutrition and wellness. I’ve always been a major foodie, and as I’ve aged, the full impact of my love of food—and not-necessarily-healthy eating habits—caught up to me. In an effort to make positive changes in my life (and hopefully yours, too), I created this website where I could share great-tasting, craveable, healthy recipes.
