Meatless Monday: Spanish Zucchini Tortilla

Some of the best recipes in the world are built from the simplest ingredients.

Eggs. Potatoes. Onion. Olive oil.

Nothing flashy. Nothing complicated.

And yet somehow, when these ingredients come together the right way, they create something deeply comforting—something that feels far more special than the ingredient list would suggest.

That’s exactly what makes a Spanish tortilla so magical.

The first time I tried one, I expected something closer to an omelet. What arrived instead was thick, golden, soft in the center, and layered with flavor from slowly cooked vegetables and rich olive oil. It felt rustic in the best possible way—the kind of dish you imagine being served in a tiny café tucked down a side street somewhere in Madrid.

This version adds zucchini, which brings freshness and a subtle sweetness that lightens the richness of the eggs and potatoes beautifully. As the zucchini softens into the tortilla, it almost melts into the center, creating a texture that’s creamy without needing cream.

And honestly? The flipping part is half the fun.

There’s a moment when you place the plate over the pan and commit to the flip that feels oddly dramatic every single time. But once you do it successfully, you suddenly feel like a much more confident cook than you were ten minutes earlier.

That’s part of why I love recipes like this.

They’re approachable enough for a weeknight meal but interesting enough to feel like you’re trying something new. They invite you into another style of cooking—slower, simpler, more ingredient-focused.

And when you slice into that golden tortilla and see the layers inside?
Completely worth it.

Spanish Zucchini Tortilla

Ingredient List

1 tbsp olive oil
1 small potato, peeled and chopped
1 small onion, chopped
½ small zucchini, thinly sliced
6 eggs
Salt & pepper, to taste

Directions

Cook the vegetables
Heat olive oil in a non-stick frying pan over medium-high heat.
Add the chopped potato and onion and cook for about 4 minutes, stirring occasionally.
Next, add the sliced zucchini and sauté for another 4 minutes, until the vegetables begin to soften and lightly caramelize.

Prepare the egg mixture
In a bowl, whisk the eggs and season generously with salt and pepper.
Transfer the cooked vegetables into the bowl and mix well.

Cook the tortilla
Using the same pan, lower the heat and pour in the egg mixture.
Spread everything evenly across the pan.
After about 3 minutes, gently run a spatula around the edges to prevent sticking.
Continue cooking for 8–10 minutes, depending on your stove and pan size.

Flip the tortilla
Place a large plate over the frying pan.
Carefully flip the tortilla onto the plate, then slide the uncooked side back into the pan.
Cook for another 5–6 minutes until fully set.

Serve
Remove from heat and allow to cool slightly before slicing.
Serve warm.
Makes 2 servings.
