This easy Tortilla Española, Spanish Omelette, is made with potatoes, eggs, and onions. A perfect brunch recipe rooted in Spanish and Puerto Rican tradition.
Peel and slice the potatoes and onions. Place the potatoes in cold salted water to keep them from turning brown.
Cook onions in olive oil in a non-stick skillet over medium heat until translucent. Strain and set aside, reserving the oil.
In the same pan, arrange the potatoes in a single layer and cook covered over low heat until tender. Sliced potatoes may cook faster than diced potatoes.
Whisk eggs with salt. Mix in ricotta if using. Add the cooked onions and stir gently.
Pour the egg mixture over the potatoes into the skillet. Cook over medium heat until the edges are set, then lower the heat and cover.
Once the bottom is set, flip the tortilla using a plate or lid and return it to the skillet to finish cooking for another five to eight minutes. When a knife or fork comes out mostly clean, it is ready.
Slide the tortilla onto a plate and let it cool slightly.
Garnish with parsley or cilantro and serve.
Notes
Keep the heat low to avoid burning the eggs.
Let potatoes cook in their own steam by keeping the pan covered.
Use evenly cut slices for uniform cooking.
Cook onions until lightly golden to add depth.
Serve warm or at room temperature.
Use a small cast iron skillet if you want a more compact tortilla that is easier to flip.
If the tortilla isn't cooking or setting fast enough, gently lift the edges and tilt the pan to let the uncooked egg run underneath.
