Total Time: 55 minutes
Servings: 8
Yield: 1 frittata
Dietary Type: Gluten-Free

Ingredients

4 medium red potatoes
8 large eggs
3 tablespoons parmesan cheese, grated
2 tablespoons fresh parsley, chopped or 2 tablespoons basil, chopped
¾ teaspoon salt
¼ teaspoon black pepper
1 ½ tablespoons olive oil
1 medium onion, halved and thinly sliced
1 garlic clove, minced
1 tablespoon butter

Equipment Needed

Medium saucepan
Large bowl
Whisk
Large ovenproof skillet (preferably cast iron)
Spatula
Serving plate

Instructions

Begin by preparing the potatoes. Place the red potatoes in a medium saucepan and add enough water to cover them by about an inch. Bring the water to a boil over high heat. Once boiling, reduce the heat to medium and gently boil the potatoes until they are tender when pierced with a knife – this should take about 15 to 20 minutes.
Once the potatoes are cooked, carefully drain them in a colander. Let them cool slightly until they are easy to handle. Then, peel the potatoes and cut them into ¼-inch-thick slices. Set aside.
While the potatoes are cooking, prepare the egg mixture. In a large bowl, whisk the 8 large eggs until they are frothy and light. This incorporates air and helps create a fluffy frittata.
Add 3 tablespoons of grated parmesan cheese, 2 tablespoons of chopped fresh parsley (or basil), ¾ teaspoon of salt, and ¼ teaspoon of black pepper to the bowl with the eggs. Whisk everything together thoroughly until all the ingredients are well blended. Set aside.
Preheat your oven to 350°F (175°C).
Now, prepare the onion mixture. In a large ovenproof skillet (cast iron works beautifully for this), heat 1 ½ tablespoons of olive oil over medium heat. Add the halved and thinly sliced medium onion to the skillet. Cook the onion, stirring often, until it becomes lightly golden and softened – about 10 to 12 minutes. Slow and steady cooking is key to getting the onions perfectly caramelized.
Add the minced garlic clove to the skillet with the onions and cook, stirring constantly, for just 1 minute, until fragrant. Be careful not to burn the garlic, as it can become bitter.
Add 1 tablespoon of butter to the skillet and reduce the heat to medium-low. This will add richness and flavor to the frittata.
Add the sliced potatoes to the skillet with the onions and garlic. Gently mix everything together, ensuring that the potatoes are evenly distributed throughout the skillet.
Slowly pour the prepared egg mixture into the pan, over the potato and onion mixture. Do not stir the mixture at this point. Let the egg mixture settle and begin to cook around the edges.
Cook the mixture on the stovetop, undisturbed, for 2 minutes. This will help the bottom of the frittata set and prevent it from sticking to the pan.
Carefully transfer the skillet to the preheated oven and bake until the eggs are cooked through and the frittata is set. This should take about 15 to 18 minutes. The frittata is done when the center is no longer jiggly and a knife inserted into the center comes out clean.
Remove the skillet from the oven and let it sit for 2 minutes. This allows the frittata to settle and makes it easier to remove from the pan.
Use a spatula to gently loosen the edges of the frittata from the skillet. Then, carefully slide the frittata onto a serving plate.
Let the frittata cool for 5 minutes before slicing and serving. This allows the flavors to meld together and prevents it from falling apart when cut.

Expert Tips & Tricks

For an even fluffier frittata, separate the eggs. Whisk the whites until soft peaks form, then gently fold in the yolks with the other ingredients.
Don’t overcook the onions. They should be lightly golden and softened, not browned or burned.
If your skillet is not ovenproof, you can transfer the mixture to a greased baking dish before baking.
To prevent the frittata from sticking, make sure your skillet is well-seasoned or use a non-stick skillet.
If the top of the frittata is browning too quickly in the oven, cover it loosely with aluminum foil.

Serving & Storage Suggestions

This potato and onion frittata can be served warm, at room temperature, or even cold, making it a versatile dish for any occasion. It’s delicious on its own or as part of a larger brunch spread. Pair it with a side salad or some crusty bread for a complete meal.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, you can gently warm it in a skillet over low heat, in the oven at 300°F (150°C), or in the microwave. The frittata is best consumed within a day or two, as the texture can change slightly over time. I don’t recommend freezing it, as the texture of the eggs can become rubbery upon thawing.
