What is the difference between an omelet and a frittata?

Frittatas are an easy way to elevate your standard eggs for breakfast, brunch—or any meal. A frittata feels more luxurious, yet is still extremely simple to cook.

A frittata is a one-skillet recipe made with beaten eggs, milk or cream, and cooked both on the stovetop and finished in the oven. Frittatas are also usually stuffed with fillings like vegetables, herbs, cheese, or meat.

While frittatas and omelet sound similar on paper, there are a few differences that set the two apart:


The omelet originated in French cuisine, while the frittata originates from Italy and is sometimes referred to as an “Italian omelet.”


To make frittatas, eggs and cream are combined and baked to form custard-like mixture, whereas omelet recipes eggs are blended together just until mixed, then cooked entirely on the stovetop.


In frittatas, fillings are combined with the egg batter in the skillet, while in omelets, the fillings are served on top or folded inside the egg.


A frittata is cooked slowly over low heat while an omelet is cooked quickly over higher heat—cooking frittata in cast iron is a great way to get a delicious result.

How to coo​k a frittata in a cast iron skillet?

Because of their great heat retention and stove-to-oven versatility, cast iron skillets are the perfect pan for making frittatas. Our cast iron frittata recipe is delicious and highly customizable; you can switch up the fillings to whatever suits your likings.

Frittatas are also a great breakfast/brunch food when entertaining, and our recipe can be scaled up or down to suit the size of your gathering. Our standard recipe, cooked in a No.8 Field Skillet, serves six, but you can increase the amount of eggs and fillings and cook your frittata in a Field No.12 Skillet to serve a larger group, or use a Field No.4 Skillet to make a single-serving frittata.

Recipe: Cast Iron Frittata

Yield: 6 servings



Preheat the oven to 350°F. In a large bowl, combine the eggs with the milk, salt, and pepper to taste. Whisk just until no visible egg whites remain.


In a Field No.8 Skillet, heat the olive oil over medium heat. Add the onions and cook, stirring frequently, until softened, about 5 minutes. Pour the egg mixture over the onions and add the shredded cheese (if using) and any mix-ins. Stir until well combined. If using crumbled goat cheese or feta; sprinkle evenly over the top.


Cook the egg mixture, without stirring, until the edges are set and just begin to pull away from the side of the skillet, about 7 minutes.


Transfer the skillet to the oven and bake until the eggs are just set (they should barely jiggle when you shake the pan), 15 to 20 minutes.


Let the frittata cool for at least 10 minutes before slicing and serving. The frittata can be made an hour or two ahead of time; reheat (if needed) in a 250°F oven.

Best practices when cooking frittata in cast iron pan

Simple mistakes can occur when cooking frittatas, which prevent your cast iron frittata from living up to its highest potential. Here are some of our best practices when cooking a frittata in cast iron skillet:


Make sure to thoroughly whisk together your eggs and cream until no whites remain to get the perfect custard-y consistency.


Dairy turns frittatas into a sort of rich, creamy egg cake—don’t skimp on this ingredient and go for the whole-fat milk or cream instead of skim milk.


Cook your meats before adding them to the frittata so that they get some caramelization before going into the frittata—and to make sure they’re fully cooked through.


Use the best pan possible—like Field cast iron skillets—you want a pan that retains heat well so that it cooks your frittata perfectly.


Follow the recipe’s cooking time and don’t overbake! You’ll miss out on the tender, custard-y texture if your frittata is in the oven for too long.
