For ultimate convenience, we cook them in the air fryer. This makes it a virtually fool-proof and stress-free recipe! All you have to do is toss the potatoes in oil and seasoning, then throw them in your air fryer basket. 

If you don’t have an air fryer or prefer not to use it, we’re also including instructions to cook them in your oven on a baking sheet. 


All the ingredients needed to make cheesy fiesta potatoes in prep bowls on a white background.

  • Potatoes – I used Yukon Gold potatoes. 
  • Oil – Vegetable, olive, and avocado oils all work great. 
  • Flour – Use all-purpose flour. 
  • Cornstarch – This helps give the potatoes the crispy exterior. 
  • Seasonings – Chili powder, garlic powder, onion powder, cumin, paprika, and salt.
  • Nacho Cheese – You can use store-bought nacho cheese or make copycat Taco Bell cheese.
  • Sour Cream – Use full-fat sour cream for best flavor.

How To Make

To make the cheesy fiesta potatoes, grab a cutting board, a knife, and the ingredients. If you are opting for the oven method, line a baking sheet with foil.

  3. Be sure to add your favorite toppings and get creative with your own twist! Salsa, hot sauce, green onions, and pickled jalapeños are some of our favorites.

To store your Cheesy Fiesta Potatoes, allow them to cool completely, then transfer them to an airtight container. They can be refrigerated for up to three days. 


To reheat, simply pop them in the oven at 350°F for about 10 minutes or until warmed through. Alternatively, you can use an air fryer at 400F for 6-7 minutes.
