Boil or steam the diced potatoes until tender, about 10-15 minutes. Drain well.
In a bowl, mash the potatoes with olive oil, chili powder, cumin, garlic powder, onion powder, salt, and pepper.
Heat about 1 inch of vegetable oil in a skillet over medium-high heat.
Warm the corn tortillas by dipping them briefly in the hot oil, then place a spoonful of the potato mixture in the center. Fold the tortilla in half to create a taco shape.
Fry the tacos for 2-3 minutes per side, until golden brown and crispy.
Remove tacos from the skillet and drain on paper towels.
Serve immediately with your favorite toppings and salsa.
Notes
For an air fryer method, place the filled and folded tortillas in the air fryer basket and cook at 400°F (200°C) for 8-10 minutes, flipping halfway through, until crispy.
You can also bake the tacos on a baking sheet at 400°F (200°C) for 15-20 minutes, flipping once, until crisp.
These tacos are a great base for a taco night board, allowing everyone to customize their own.
Consider serving with a vibrant salsa verde or a smoky chipotle salsa.
