Potato Frittata is fluffy, delicate and brimming with classic Italian flavors: layers of tender, sliced potato, prosciutto, parmesan cheese and earthy fresh rosemary. It's delicious at any temperature, hot, warm, or cold and welcome for any meal of the day. Serve with a green salad for a light lunch or dinner or with with fresh fruit for breakfast or brunch.
Until the 1950s, frittata was mostly seen as nothing more than a humble omelet outside of Italy, but the world has taken note of how much the dish has to offer. It’s more than worthy of having its own name, method, and recipe.
Ingredients You Need to Make Potato Frittata
- Yukon Gold Potatoes: Yukon Gold potatoes or other waxy potato
- Shallots: or sweet onion
- Olive Oil: ideally extra virgin olive oil
- Eggs: large or extra large
- Milk: or half and half for a richer frittata
- Fresh Rosemary or Fresh Thyme: or ½ teaspoon dried thyme
- Parmesan Cheese: or Pecorino Romano cheese
- Prosciutto: or bacon or pancetta or skip the meat for a vegetarian option
- Kosher Salt and Freshly Ground Black Pepper
Italian, the word frittata is a derivative of friggere and loosely translates as 'fried'. It began as a general term for eggs cooked in a skillet in any number of ways.
Though a frittata is similar to an omelet (also spelled omelette) as a list of ingredients, the difference comes in how they're cooked. With a frittata, you combine the filling ingredients with raw, beaten eggs rather than spreading them over mostly cooked egg. And instead of folding the egg mixture over the filling at the end, as you would an omelet, a frittata is not folded. The filling is dispersed with the raw egg and they cook together, more like a crustless quiche and flipped whole on the stovetop or, my preference, finished in the oven.
Frittatas are cooked slower and at a lower temperature than an omelette. And for frittatas the eggs are beaten until frothy to incorporate more air to create a fluffier, thicker final dish that can hold more filling.
There are endless options for frittata fillings, the key is to swap in similar amounts of related ingredients. For example:
- Instead of Parmesan cheese, use Pecorino Romano cheese or a good melting cheese like Monterey jack, mild or sharp cheddar cheese, or mozzarella. Or branch out to other Italian cheeses like Taleggio or Fontina.
- Swap in thin slices or cubes of cooked sweet potato, butter sautéed mushrooms or leftover cooked vegetables for the potatoes.
- Use thinly sliced yellow onion or sweet onion or chopped green onions for the shallot in this recipe. Caramelized onions would also be an excellent substitution.
- Instead of prosciutto, add pancetta, bacon or sweet or hot Italian sausage.
- Add in a handful of baby spinach or arugula (don't go overboard though as you could end up with a watery frittata).
- Keep in mind that you'll need to cook whatever fillings you choose before adding them to the egg mixture (except for cheese and meats that don't require cooking, like prosciutto).
- Be sure to use an oven safe skillet. Once you add the raw egg to the cooked filling ingredients on the stovetop, you'll transfer the skillet to the oven for the majority of the cooking time. Some versions of frittata spend more time (or cook completely) on the stovetop. With this recipe, you're already using the oven to evenly cook the potatoes and shallots, so it makes sense to finish the frittata there as well. As a bonus, you'll avoid the mess of flipping it and spend less time at the stove.
A Note about Cooking Temperature
Some recipes recommend baking frittata at a temperature of 400˚F (or higher), but in my experience, this is too high. Slower cooking results in a more tender texture; 350˚F is ideal.
