Cook time10 min

First, peel the onion and use a mandoline to cut it into thin slices.
Pour some olive oil into a pan and add the sliced onions. Cook, covered, over medium heat for about 10 minutes, stirring occasionally, until the onions are soft and wilted.
Meanwhile, beat the eggs in a bowl. Add the grated parmesan, a pinch of salt, a pinch of pepper and mix everything well.
When the onions are cooked, spread them evenly across the bottom of the pan. Then add the beaten egg mixture, making sure it is evenly distributed (hold the pan by the handle and rotate it to spread the mixture). Cook the frittata for about 7 minutes over medium/low heat with the lid on.
After this time, check whether the edges come away easily and the bottom is cooked through. Then turn the onion frittata over using a plate (or a flat lid).
Slide the frittata back into the pan and continue cooking the other side for about 4–5 minutes over medium heat, without the lid.
The onion frittata is ready. You can serve it hot, warm, or cold—it's up to you!

FAQ ❓

How long can you store onion frittata?

It will keep in the refrigerator for a couple of days, well covered with plastic wrap or stored in an airtight container.

How long does onion frittata take to cook?

The cooking times are approximate, as they depend on how you like your frittata. If you follow the instructions, you’ll get a thoroughly cooked onion frittata with a pleasant texture.

What can I use instead of grated Parmigiano Reggiano?

Grated Grana Padano or pecorino will also work well in onion frittata. If you use pecorino, add less salt to the beaten eggs.

How should the onions be cooked for frittata?

Cooking the onions properly is very important. Be sure to use the lid: the steam trapped inside will soften them, making them ideal for frittata.

Can I bake onion frittata in the oven?

Yes. Follow the same method as for frittata cooked in a pan. Once the onions have softened, add them to the beaten eggs and mix. Transfer everything to a baking dish lined with parchment paper and bake at 200°C for about 20–25 minutes (as usual, the cooking time will depend on your oven).
