Happy Earth Day! Thought maybe this a good time to prepare a meatless meal. This is not a traditional Spanish tortilla, since it has cheese in it, but the crust that develops on this omelet with the addition of parmesan, is worth breaking the rules. I’ve prepared this dish a handful of times and more than a few times, some of the tortilla has broken off while coming out of the pan. Don’t stress about it! It’ll still be delicious and you are cutting it anyway. Serve this with a simple green salad, dressed in olive oil and salt and maybe a glass of wine…

Tips:

• This has nothing to do with the bread-like tortilla. It’s a Spanish version of an omelet or Italian frittata.

• Go the distance and serve some Serrano ham or prosciutto on the side or on the salad- oops, forgot I said meatless.

• The dish is delicious at room temperature and even the next day for lunch.

Spanish Tortilla

Recipe originally from Food52

Serves 6

PREP 30 minutes

COOK 20 minutes

INGREDIENTS

2 pounds white or Yukon Gold potatoes, peeled

Salt

1 medium onion, chopped

3 tablespoons olive oil or vegetable oil

8 eggs

Freshly ground black pepper

1/3 cup freshly grated Parmesan cheese

1 1/2 tablespoons unsalted butter

INSTRUCTIONS

1. Place the potatoes in a medium pot. Cover with water, season with about a tablespoon of salt, and bring to a boil. Reduce the heat and simmer until the potatoes are just tender when prodded with a fork, 20 to 25 minutes. Drain and let cool, then cut into 1/8-inch slices and put them in a large mixing bowl.

2. Heat the oven to 400 degrees.

3. Meanwhile, warm 1-1/2 tablespoons oil in a medium pan over medium heat. Add the onions, season with salt, and cook until translucent and lightly browned, about 10 minutes. Scrape the onions into the bowl with the potatoes.

4. Lightly whisk the eggs until smooth, then add them to the potatoes and onions, and gently fold everything together. The potatoes should not be sticking together -- make sure the egg separates each slice. Season with salt and pepper and fold once more.

5. Set a large nonstick or well-seasoned cast iron pan over medium high heat. Add the remaining 1 1/2 tablespoons oil and the butter. When the butter foams, pour in the potato-and-egg mixture and pat it down so it's even on the top. Sprinkle the cheese on top, let the eggs set around the edges, and transfer the pan to the oven. Bake until the eggs are almost set in the middle and the tortilla is browned around the edges, about 20 minutes.

6. Remove the pan from the oven and let it cool on the stovetop. Run a thin spatula or knife around the edge of the tortilla to loosen it, then invert it onto a plate (this may be a 2-person job). If you'd like to serve the tortilla warm, invert it while it's still warm. Slice and serve.
