Flautas de Papa with Salsa Roja (Potato Flautas)

Crisp potato flautas bring together two of Mexican cooking’s most satisfying textures: soft, seasoned filling and brittle, golden corn tortilla. The potato is mashed with onion, garlic and cumin, then rolled tightly in warmed tortillas and fried until crunchy enough to hold up to generous toppings. A rustic salsa roja made with ripe tomatoes and guajillo chilli adds warmth, acidity and gentle heat, while shredded romaine, sour cream and lime keep each serving fresh. They work well as a vegetarian dinner, snack-style plate or sharing dish, especially when served straight from the pan while the shells are still crisp.

Why this recipe works

  • Crisp tortilla shell: Warming the corn tortillas before rolling helps them hold their shape, while frying in batches keeps the exterior golden and crisp.
  • Simple filling, bold finish: The potato filling is mild and savoury, giving the warm tomato and guajillo salsa space to bring depth, acidity, and gentle chilli flavour.
  • Easy to serve casually: The flautas can be plated individually or served sharing-style with salsa, lettuce, sour cream, and lime added at the table.

Get the most out of this recipe

Adjust the heat

  • For a gentler salsa: Use a mild chilli powder in place of guajillo chilli powder and add lime gradually so the salsa stays bright without tasting sharp.
  • For more heat: Add a hotter chilli powder or serve with a spicy table salsa, keeping the potato filling mild so the heat stays balanced.

Texture tips

  • Keep the oil steady: Fry in batches and avoid crowding the pan, as a drop in oil temperature can make the tortillas absorb oil instead of crisping.
  • Top just before serving: Add salsa, lettuce, and sour cream at the last moment so the flautas stay crisp underneath.
  • Cool the filling slightly: Let the mashed potato cool a little before rolling; a firmer filling is easier to shape and less likely to squeeze out.

Make-ahead tips

  • Make the components ahead: The potato filling and salsa roja can be prepared in advance, then the tortillas can be filled and fried closer to serving.
  • Store separately: Keep fried flautas and salsa in separate airtight containers so the tortillas do not soften in the fridge.
  • Re-crisp before serving: Reheat the flautas in a 200°C (390°F) oven until hot and crisp, and warm the salsa separately before adding lime to taste.

Ingredient notes

  • Use corn tortillas: Corn tortillas give flautas their characteristic flavour and crisp snap; warm them well so they roll without cracking.
  • Choose ripe tomatoes: Ripe tomatoes soften quickly into a fuller-tasting salsa roja and need less adjustment at the end.
  • Finish with lime: Add lime after the salsa has simmered so the acidity stays fresh and can be adjusted to taste.

  1. Peel the potatoes and cut into even chunks. Put them in a large pot, cover with water, and add 1 tsp of the fine sea salt. Bring to the boil and cook for 12 to 15 minutes, until very tender.
  2. Meanwhile, finely chop half the onion and mince 1 garlic clove for the filling. Thinly slice the remaining onion and mince the remaining garlic for the salsa. Shred the romaine lettuce and cut the lime into wedges.
  3. Drain the potatoes well, then mash until smooth. Stir in the chopped onion, 1 minced garlic clove, the ground cumin, and 0.5 tsp of the fine sea salt. Let the filling cool slightly so it is easier to roll.
  4. Make the salsa roja: put the tomatoes, sliced onion, remaining garlic, guajillo chili powder, water, and 0.5 tsp fine sea salt in a saucepan. Bring to a simmer and cook for 8 to 10 minutes, until the tomatoes collapse and the onion is soft. Crush with a potato masher for a rustic salsa, then squeeze in a little lime to taste.
  5. Warm the corn tortillas briefly in a dry frying pan so they are pliable. Spoon the potato filling down the centre of each tortilla and roll up tightly. Keep them seam-side down while you heat the oil.
  6. Pour the vegetable oil into a frying pan to a depth of about 2 cm and heat over medium-high until shimmering. Fry the flautas in batches, turning with tongs, for 2 to 3 minutes per side until golden and crisp. Drain briefly on a plate and season lightly with a pinch of fine sea salt.
  7. Serve the flautas topped with warm salsa roja, shredded romaine lettuce, and spoonfuls of sour cream. Finish with extra lime wedges for squeezing at the table.

Recipe notes

Tips

  • For the crispest flautas, keep the oil at a steady medium-high heat and avoid overcrowding the pan, which drops the temperature.
  • If the tortillas crack as you roll, warm them a little longer so they soften before filling.
  • If serving anyone who is vulnerable, use pasteurised sour cream and ensure the flautas are fried until piping hot throughout.

Substitutions

  • Replace romaine lettuce with iceberg lettuce for extra crunch.
  • Replace sour cream with greek yogurt for a lighter topping.
  • Replace guajillo chili powder with mild chili powder for a gentler heat.

Storage

  • Refrigerate up to 3 days
  • Store flautas and salsa separately in airtight containers. Reheat flautas in a 200°C (390°F) oven for 8 to 10 minutes until hot and crisp; warm the salsa gently in a saucepan and add lime to taste after reheating.
