Ingredients
• 1 cup / 240g (8.5 oz) leftover mashed potatoes, chilled
• 8 soft corn tortillas
• 1/4 pound / 113g (4 oz) Spanish Manchego cheese, cut into 16 small sticks
• 16 slices pickled jalapeño pepper
• 4 tablespoons / 57g (2.01 oz) unsalted butter
Instructions
1. Prepare the Tacos: Spoon 1 tablespoon (15 ml / 0.5 fl oz) of chilled mashed potato into the center of each tortilla. Use the back of the spoon to flatten the potatoes, leaving a 1-inch border around the edge.
2. Add the Fillings: Arrange 2 sticks of Manchego cheese and 2 slices of pickled jalapeño over the potato layer on each tortilla.
3. Fold and Seal: Gently fold each tortilla in half to create a half-moon shape, pressing down lightly to seal the contents inside.
4. Cook the First Batch: In a large skillet over medium heat, melt 2 tablespoons (30 ml / 1 fl oz) of the butter. Once shimmering, carefully place 4 tacos into the pan.
5. Fry Until Golden: Cook for 3–4 minutes on each side, until the tortillas are deeply golden brown and crispy, and the cheese is fully melted.
6. Drain and Repeat: Transfer the cooked tacos to a paper towel-lined plate to absorb any excess butter. Repeat the cooking process with the remaining butter and tacos.
7. Serve: For easy eating, snip the tacos in half and serve immediately with your favorite salsa for dipping.

Pro Tips
• for Perfect Potato Tacos
• Use cold, firm mashed potatoes. Warm or overly creamy potatoes will make the tacos soggy and difficult to fold and fry.
• Warm your corn tortillas for 15-20 seconds in a microwave or a dry pan before filling. This makes them pliable and prevents them from cracking when you fold them.
• Don’t overcrowd the skillet. Frying in batches ensures each taco has enough space to get exceptionally crispy instead of steaming.
• Feel free to swap the cheese! A sharp cheddar, Monterey Jack, or a crumbly cotija would also be delicious in this recipe.
FAQ
Q: Can I make these potato tacos vegan
A: Absolutely! To make this recipe vegan, simply substitute the Manchego cheese with your favorite dairy-free cheese shreds and use a plant-based butter or a neutral oil like avocado oil for frying.
Q: How can I add more protein to these vegetarian tacos
A: To boost the protein, you can mix 1/2 cup (480 ml) of black beans or pinto beans into the mashed potato filling. Serving them with a side of Greek yogurt or a sprinkle of toasted pepitas (pumpkin seeds) also adds a nice protein kick.
Q: Are these crispy potato tacos gluten-free
A: Yes, this recipe is naturally gluten-free as long as you use 100% corn tortillas. Always double-check the packaging of your tortillas to ensure they are certified gluten-free and not a corn/wheat blend.
Q: Can I prepare these vegetarian tacos ahead of time
A: Yes, you can assemble the tacos (fill and fold them) up to a day in advance. Store them in a single layer in an airtight container in the refrigerator. Fry them just before serving for the best crispy texture.
