Method
Prep and preheat
- Preheat oven to 425°F and line a sheet pan with foil, so the potatoes roast hot and crisp.
Season the potatoes
- Toss diced potatoes with olive oil, taco seasoning, garlic powder, salt, and pepper until evenly coated, with every cube visibly speckled.
Roast until golden and crispy
- Spread potatoes in a single layer on the sheet pan and roast for 25–30 minutes, flipping once halfway, until golden and crispy with browned edges.
Melt cheddar and finish
- Transfer to a serving dish or cast iron and top with shredded cheddar, then return to the oven for 2 minutes until melted and glossy.
Top and serve
- Dollop with sour cream, scatter fresh cilantro and jalapeño slices on top, and finish with lime wedges for squeezing right before eating.
Notes
For extra crunch, avoid crowding the potatoes—use a single layer and give them space on the sheet pan so steam can escape. Store leftovers in the refrigerator up to 3 days; reheat on a sheet pan in a 425°F oven until hot and re-crisped. Freezing is not recommended because the toppings and potatoes lose texture. For a lighter option, swap sour cream for plain Greek yogurt while keeping the cheddar amount the same.
