This Caramelized Onion-Potato Egg White Frittata is every bit as hearty as a whole egg frittata, and you might even like it better! Recipes with egg whites, like this one, can be very versatile and can take on several delicious flavors at once. Before we begin, so you understand this recipe, frittata is the word for omelet in Italian.
Do you ever order an egg white omelet because you think it’s the “light and healthy” choice?
Well, it’s certainly a healthy choice — however, why does it have to be light? Don’t get me wrong, light can be delicious, but when I’m especially hungry, I want something that tastes hearty, rich, and healthy, but not light. Know what I mean?
Well, as it turns out, recipes with egg whites do not always have to be light. And let me tell you, this scrumptious Caramelized Onion-Potato Egg White Frittata totally does the trick!
There is in fact a trick to this.
I NEVER whisk or mix egg whites in any way, shape or form, when I’m using them for an omelet of any sort
Simple — so they don’t taste light. And by the way, they still are light — in the healthy sense of the word.
The result of not mixing them is a texture that’s thick and smooth. This is how I get the “hearty.” The “rich,” I get by developing the flavors of the added ingredients.
And in the case of potato egg white frittata, it’s the caramelized onions that bring it on.
The technique for adding the whites to recipes with egg whites in omelets and frittatas. . .
Crack the egg, obtain the whites and add them to the pan as they are. NO mixing of any kind — not even to season them, which you’ll do later in the cooking process.

This Caramelized Onion-Potato Egg White Frittata is every bit as hearty as a whole egg frittata, and you might even like it better! Recipes with egg whites, like this one, can be very versatile and can take on several delicious flavors at once.
- olive oil for the pan
- 2 1/2 cups yellow onion, thinly sliced
- 2 ½ teaspoons garlic, minced
- 1 tablespoon fresh thyme, finely chopped
- 1 cup small red potatoes, thinly sliced
- 12 large egg whites
- sea salt and freshly ground black pepper
Coat the bottom of a 10-inch, non-stick sauté pan with olive oil, and place it over medium-high heat.
Add the onions and garlic and sauté, stirring every couple of minutes, until he onions are soft and nicely browned, about 7 minutes.
Mix in the thyme and let this cook for another minute or so -- until it's very aromatic.
Add the potatoes and sauté for a couple of minutes. Then turn the heat to low, cover and let the potatoes steam until they are tender, 8 to 10 minutes.
Season generously to taste with salt and pepper. (Here's how.)
Turn the heat off and remove half of the onion-potato mixture from the pan. Set it aside, and then arrange the other half, so that it neatly covers the bottom of the pan.
Crack the 12 egg whites into a bowl. (You can save the yolks for making ice cream or custard.) Do not mix or whisk the egg whites in any way. (Not even for a second!)
Turn the heat to medium, and pour the egg whites into the pan, evenly on top of the arranged onion-potato mixture. Then quickly arrange the remaining half of the onion-potato mixture directly on top of the egg whites. Most of this will stay "afloat."
Cook until you see that the bottom is opaque, then reduce the heat to low, cover and cook just until all of the whites have solidified, about 15 minutes.
Once the frittata is cooked, gently loosen the edges and slide it onto a large plate. Let it cool for a few minutes and then serve.
