The abundance of farm fresh leeks is overwhelming. Alongside onions, garlic, and shallots, they are the “it” item in farmers markets right now. Though favorites in everyday cooking, leeks seem too ordinary to make it the source of inspiration when making a dish. Asides from vichyssoise, can you think of any other dish in which the leek takes the leading role?
The inspiration for this dish comes from the very humble, Tortilla Espanola. This potato omelet is one of the only Spanish recipes I actually enjoy. While beautiful in its simplicity, eggs, potatoes, onions, and olive oil, I wanted to play with the ingredients I had at hand. The leeks bring a mild sweetness to the traditional recipe, the potatoes, texture and body, and the rosemary, a sweet herbaceous fragrance. Though I will not compete with the traditional recipe, I think it is perfect for this weather, light, delicious, and fresh.
And while I will patiently continue to await springs delicacies (Asparagus, where are you?); I will leave you with this. 
Spring’s Spanish Omelet

- Yield: 3 servings 1x
Description
This Spanish Spring Omelet is a delightful twist on the traditional Tortilla Espanola, featuring leeks, potatoes, and fresh rosemary for a light and flavorful meal.
Ingredients
- 1 leek, thinly sliced
- 4 small potatoes, thinly sliced
- 3 eggs
- Several rosemary leaves
- Pinch of salt
- Pinch of cumin
- 2 tbsp (30 ml) olive oil
- Fresh ground pepper to taste
- 1/2 cup (120 ml) water
Instructions
- Thinly slice the potatoes and leeks. Set aside.
- In a small-medium saucepan, heat 1 tbsp of olive oil over low heat. Add the leeks and a pinch of cumin. Cook slowly, stirring occasionally, until the leeks are soft and caramelized, about 10 minutes.
- In another pan, add the sliced potatoes and 1/2 cup of water. Cook over medium heat until the potatoes are tender and the water has evaporated, about 10 minutes.
- In a bowl, beat the eggs with a pinch of salt and fresh ground pepper. Add the caramelized leeks, cooked potatoes, and rosemary leaves to the eggs. Stir to combine.
- In a non-stick skillet, heat the remaining tbsp of olive oil over medium heat. Pour the egg mixture into the skillet, spreading it evenly. Cook for about 5 minutes, or until the edges start to set.
- Carefully flip the omelet using a plate to assist, and cook the other side for an additional 3-5 minutes, or until the omelet is fully set and golden brown.
- Slide the omelet onto a serving plate, cut into wedges, and serve warm.

Frequently Asked Questions
Why are the leeks cooked slowly for 10 minutes rather than just sautéed quickly?
The article explains that slow caramelization is the point — cooking the leeks over low heat for 10 minutes with a pinch of cumin draws out their mild sweetness, which is what distinguishes this version from a standard Tortilla Española. Rushing them would produce a sharp, raw leek flavor instead.
Why are the potatoes cooked in water rather than fried in olive oil?
The recipe simmers the thinly-sliced potatoes in 1/2 cup of water over medium heat until tender and the water has evaporated — about 10 minutes. This is lighter than the traditional olive-oil confit method and means the potatoes absorb the egg mixture better without adding extra fat.
How do I flip the omelet without breaking it?
The instructions say to use a plate to assist with the flip: slide the set omelet onto a plate, then invert the pan over the plate and flip both together so the uncooked side lands in the skillet. Cook the second side for 3–5 minutes until golden brown.
