Onion omelette, the sweetness you don't expect (and the chemistry makes it irresistible)
Onion frittata is one of those dishes that seems humble, yet hides a complexity of flavor that few imagine.
- 4 medium onions (about 500 g)
- 6 medium eggs
- 50 g of grated Parmigiano Reggiano
- 2 tablespoons extra virgin olive oil
- 1 knob of butter (optional)
- Salt and black pepper to taste
- Chopped fresh parsley (optional)
- Preparing the omelette
- The secret to this frittata is the slow cooking of the onions. Start by peeling them and slicing them thinly, not too thickly, so they soften evenly. In a large nonstick skillet, heat the oil and butter over medium-low heat.
- Add the onions and a pinch of salt. The salt helps draw out moisture and speed up the caramelization process. Cover and cook for 15-20 minutes, stirring occasionally. The onions should become soft, translucent, and lightly golden. Don't raise the heat: the sweetness develops only with patience.
- While the onions are cooking, beat the eggs in a bowl with the Parmesan cheese, a pinch of salt, a pinch of pepper, and, if desired, chopped parsley. Once the onions are ready, pour them into the bowl with the eggs and mix gently. Return the pan to the heat with a drizzle of oil and pour in the mixture. Cook over medium-low heat for 5-6 minutes, until the edges start to separate and the bottom is golden brown.
- At this point, flip the frittata using an inverted plate and cook the other side for another 4-5 minutes. Serve hot or at room temperature. The result is a soft, sweet, and flavorful frittata that needs no introduction. Because onion frittata, like all things made with method, is savored down to the last bite.
The heat breaks the sulfur chains responsible for the strong odor and releases the natural sugars, which slowly caramelize.
The result is a frittata with a delicate, almost candy-like flavor that melts in your mouth. It's a traditional peasant dish, made with just a few ingredients and a lot of time. Today, with the right method, you can achieve the same result in less than half an hour.
Onion Omelette: Recipe for Making It the Old-Fashioned Way
