Description
Frittata di Cipolle is a rustic Italian dish made with deeply caramelized onions, eggs, and Parmigiano Reggiano. This simple yet flavorful one-pan recipe is perfect for any meal of the day and is naturally gluten-free and vegetarian.
Ingredients
6 large eggs
2 large yellow onions, thinly sliced
3 tbsp olive oil
2 tbsp whole milk
1/4 cup grated Parmigiano Reggiano
Salt and freshly ground black pepper, to taste
Fresh parsley, chopped (optional, for garnish)
Instructions
- Heat olive oil in a non-stick or cast iron skillet over medium-low heat.
- Add the sliced onions and cook slowly, stirring occasionally, for about 15–20 minutes until deeply golden and caramelized.
- While the onions cook, whisk the eggs with milk, Parmigiano Reggiano, salt, and pepper in a large bowl until smooth.
- Once onions are ready, spread them evenly across the skillet.
- Pour the egg mixture over the onions and gently tilt the pan to evenly distribute.
- Cook on medium-low heat, undisturbed, for about 8–10 minutes until the edges are set and the center is slightly soft.
- Finish by either flipping the frittata to cook the other side for 2–3 minutes or placing the skillet under a preheated broiler for 2–3 minutes until set and lightly golden on top.
- Let it cool slightly before slicing. Garnish with chopped parsley if desired.
Notes
Use a non-stick or well-seasoned cast iron skillet to prevent sticking.
Bake at 350°F (175°C) for 20–25 minutes as an alternative to stovetop cooking.
Yellow onions are preferred for their sweetness, but red or white onions work too.
Store leftovers in the fridge for up to 3 days or freeze for up to 2 months.
Reheat using oven or skillet to maintain texture.
