Ingredients
For the Vegan Tortilla
2 large sweet potatoes

1 small zucchini, grated
350 g chickpea flour
350 ml water
2 tablespoons olive oil, plus extra for cooking
2 teaspoons salt, or to taste
Black pepper, to taste
Ingredient Notes
Sweet Potatoes
Sweet potatoes give this vegan tortilla a slightly sweeter flavor and softer texture than traditional potatoes.
Peel them and cut them into small cubes, approximately 1 cm in size. Keeping the pieces similar in size helps them cook evenly.
Chickpea Flour
Chickpea flour is the key ingredient that replaces the eggs in this recipe. When mixed with water and cooked, it creates a firm, savory mixture that holds the vegetables together.
Onions
Do not rush the onions. Cooking them slowly allows them to become soft and lightly golden, adding sweetness and depth to the tortilla.
Zucchini
Grated zucchini adds moisture and another layer of vegetables to the tortilla. Squeeze out some excess moisture if your zucchini is particularly watery.
Olive Oil
Olive oil is important for both flavor and cooking. It also helps the edges of the tortilla cook properly and makes it easier to release from the pan.
Equipment
You will need:
Large mixing bowl
Large nonstick frying pan
Small frying pan
Sharp knife
Cutting board
Vegetable peeler
Box grater
Whisk
Spatula
Toothpick or skewer
Oven-safe frying pan or baking dish
A nonstick pan with relatively high sides is particularly helpful because the tortilla mixture is fairly thick.
How to Make Vegan Tortilla de Patatas
1. Prepare the sweet potatoes
Peel the sweet potatoes and cut them into approximately 1 cm cubes.
Try to keep the pieces similar in size so they cook evenly.
Set aside.
2. Slice and cook the onions
Peel the onions and finely slice them.
Heat 2 tablespoons of olive oil in a frying pan over medium heat.
Add the onions, cover the pan, and cook for approximately 25–30 minutes, stirring occasionally.
Continue cooking until the onions are soft and beginning to turn golden.
If they start to brown too quickly, reduce the heat.
3. Cook the sweet potatoes
Heat approximately 3 tablespoons of olive oil in a large, deep nonstick frying pan over medium-low heat.
Add the cubed sweet potatoes and season with some of the salt.
Cook gently until the sweet potatoes are tender and lightly golden.
The goal is tenderness rather than heavy browning. Reduce the heat if the potatoes begin to brown too quickly.
4. Prepare the chickpea mixture
While the vegetables are cooking, add the chickpea flour and water to a large mixing bowl.
Whisk thoroughly until smooth.
There should be no large lumps of dry flour remaining.
Season with the remaining salt and a little black pepper.
5. Add the vegetables
Add the cooked sweet potatoes, caramelized onions, and grated zucchini to the chickpea flour mixture.
Gently mix everything together until the vegetables are evenly distributed.
Taste the mixture before cooking and adjust the seasoning if necessary.
This is the easiest stage to adjust the salt.
6. Prepare the pan
Carefully clean the large frying pan used for the tortilla.
Remove any leftover pieces of onion or potato because they can burn during the final cooking stage.
Add enough olive oil to lightly coat the bottom and sides of the pan.
Heat over medium heat.
7. Add the tortilla mixture
Pour the chickpea and vegetable mixture into the hot pan.
Use a spatula to spread the mixture evenly and gently smooth the surface.
The edges should begin cooking shortly after the mixture touches the pan.
8. Cook the tortilla on the stovetop
Cook for approximately 4 minutes over medium heat.
Watch the edges carefully.
You want the outside to begin setting while the center remains softer.
9. Finish cooking in the oven
Preheat the oven to 180°C / 350°F.
Transfer the oven-safe frying pan to the preheated oven.
Bake for approximately 25 minutes.
The exact cooking time will depend on the thickness of your tortilla and your oven.
10. Check for doneness
Insert a toothpick or wooden skewer into the center of the tortilla.
Remove it slowly.
If it comes out mostly clean and dry, the tortilla is ready.
If the mixture is still wet, return it to the oven and bake for another 5 minutes before checking again.
11. Allow the tortilla to rest
Remove the tortilla from the oven and allow it to rest for several minutes.
Carefully loosen the edges with a spatula.
Place a plate over the pan and carefully turn the tortilla onto the plate.
12. Serve
Remove any excess oil from the surface with a paper towel if necessary.
The tortilla can be served warm, but it is particularly good at room temperature.
For even more flavor, refrigerate it for several hours and remove it from the refrigerator about 30 minutes before serving.
Tips for the Best Vegan Tortilla de Patatas
Cut the sweet potatoes evenly
Small, evenly sized cubes cook more consistently and make the finished tortilla easier to slice.
Cook the onions slowly
The onions are an important source of flavor. Give them enough time to soften and become lightly golden rather than cooking them quickly over high heat.
Don't skip the resting time
Allowing the tortilla to rest helps the chickpea mixture firm up and makes slicing easier.
Don't make the tortilla too thin
A thicker tortilla gives you the satisfying texture associated with a Spanish-style potato omelette.
Use a nonstick pan
A good nonstick pan makes releasing the tortilla considerably easier, especially when working with a thick mixture.
Check the center before serving
Because the tortilla is relatively thick, the outside can look cooked before the center is fully set. Always check the middle before removing it from the oven.
Easy Variations
Use regular potatoes
For a more traditional tortilla-style recipe, replace the sweet potatoes with regular potatoes.
Add fresh herbs
Fresh parsley, chives, or green onions can add freshness to the finished tortilla.
Add smoked paprika
For a slightly smoky flavor, add a small amount of smoked paprika to the chickpea flour mixture.
Add bell peppers
Finely diced red or green bell peppers can be cooked with the onions and added to the tortilla.
Make it spicier
Add chili flakes or a small amount of cayenne pepper for some heat.
Add vegan cheese
A small amount of shredded vegan cheese can be added to the mixture for a richer variation.
How to Store Vegan Tortilla de Patatas
Allow the tortilla to cool completely before storing it.
Place it in an airtight container and refrigerate for up to 3 days.
It can be enjoyed cold, at room temperature, or gently reheated.
For the best texture, remove it from the refrigerator about 20–30 minutes before serving.
How to Reheat
To reheat individual slices, place them in a skillet over low to medium heat until warmed through.
You can also reheat them in the oven at approximately 160°C / 320°F until warm.
Avoid overheating because the chickpea mixture can become dry.
