Make your own crispy fiesta potatoes at home! This simple, gluten-free recipe only requires 10 simple ingredients and is ready in under an hour.


  • 3 lbs. russet potatoes, washed
  • 1/4 cup avocado oil
  • 1/2 cup corn starch 
  • 1 tablespoon garlic powder
  • 1 tablespoon onion powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon paprika
  • 1/4 teaspoon cayenne pepper
  • 1/4 teaspoon cumin


  1. Add the potatoes to a large pot and fill it with water about 1-2 inches above the potatoes. Bring the water to a boil on high heat. Cook for about 20 minutes (timed from turning on the burner), or until slightly fork-tender. We do not want the potatoes to cook all the way since we will be baking them after this. 
  2. In the meantime, preheat the oven to 425°F and line a full sized baking sheet (or two half sheets) with parchment paper or a silicone mat. 
  3. Grab a small bowl and mix together the corn starch, garlic, onion, salt, pepper, paprika, cayenne pepper, and cumin. 
  4. Once the potatoes are parboiled, dice them into 1″ squares, and add them to a large bowl. Add oil to your potatoes and gently mix together until fully coated. Sprinkle over the spice blend and mix through until they are coated on all sides. 
  5. Transfer seasoned potatoes to the baking sheet(s) and spread out to a single layer. 
  6. Place into the oven and bake for 40 minutes, mixing potatoes halfway through. 
  7. Allow the potatoes to cool slightly before serving. Enjoy! 


  • For this recipe, we like to use russet potatoes, but Yukon Gold would work great too. If you want to put a unique twist on this recipe you can also use sweet potatoes.
  • You can also use olive oil or any oil of your choice.
  • If you don’t have any corn starch on hand, you can use all-purpose for a non-gluten-free option.
