125 ml olive oil
225 g potatoes, thinly sliced
salt and pepper to taste
1 large onion, thinly sliced
4 large eggs
2 medium tomatoes - peeled, seeded, and coarsely chopped
2 green onions, chopped
Step 1
In a large skillet, heat the olive oil over medium-high heat. Add the thinly sliced potatoes and season with salt and pepper. Cook, stirring occasionally, until the potatoes are golden brown and crispy, which should take around 10 to 14 minutes. Add the thinly sliced onions and continue to cook and stir until they are soft and beginning to brown, for about 6 to 8 minutes.
Step 2
In a bowl, whisk the eggs and season with salt and pepper. Pour the eggs into the skillet and gently stir to combine with the potatoes and onions. Reduce the heat to low and cook until the eggs begin to brown on the bottom, which should take around 4 to 5 minutes.
Step 3
Using a spatula, loosen the frittata. Place a large plate over the skillet and carefully flip the frittata onto the plate. Slide the uncooked side of the frittata back into the skillet. Cook until the eggs are set, for about 4 to 5 minutes.
Step 4
Serve the savory Spanish potato frittata warm, garnished with the chopped tomatoes and green onions.
