Have you ever roasted sweet potatoes? If you haven’t, we are hoping we can convince you to because they make the greatest side dish to any meal!

We first tried these roasted sweet potato cubes over a decade ago, inspired by our recipe for Parmesan Potatoes that we’ve always made.

Since then, we have become OBSESSED and whip them up on the regular! They take about 5 minutes to prep and 20 to bake. They are so simple and so delicious, and our go-to side along with our Roasted Brussel Sprouts and Oven Roasted Vegetables.

Why we think you’ll love it:

  • Simple. This easy side dish takes just about 5 minutes to throw together and 20 minutes to bake.
  • Flavor. The combo of sweet and savory potatoes, plus the cheese and seasonings, is out of this world!
  • Adaptable. Change this potato side dish based on the herbs and seasonings used. Make them sweeter or more savory!

  • 2 tablespoons unsalted butter, melted
  • 1 tablespoon extra-virgin olive oil – or avocado oil
  • ¼ cup grated Parmesan cheese
  • 2 teaspoons minced garlic – about cloves of garlic, How to Mince Garlic
  • ½ teaspoon garlic salt
  • ½ teaspoon Italian seasoning to change the flavors, try a combination of cumin, garlic powder, chili powder, black pepper, and paprika.
  • 2 sweet potatoes Red garnet and jewel are the most common types of orange-fleshed sweet potatoes sold in American grocery stores. Both work well in this recipe.
  • dried parsley for topping
  1. PREP. Preheat the oven to 400°F.
    • Line a baking sheet with foil and spray with nonstick cooking spray. Set aside.
  2. SEASON. Place butter, olive oil, Parmesan, minced garlic, garlic salt, and Italian seasoning in a large resealable plastic bag and mix well.
    • Peel and cut sweet potatoes into 1-inch cubes. Add to the bag and shake until well coated.
  3. BAKE. Place coated sweet potatoes on the prepared baking sheet and spread out evenly. Bake for 18–22 minutes until fork tender.
    • To make them even more crispy, flip halfway through and broil for the last minute or two.
    • Serve warm, sprinkled with dried parsley, if desired. Serve these flavorful potatoes on salads, in burritos with black beans, or grain bowls with rice, quinoa, or farro.
  • Be sure to cut even cubes so everything is roasted at the same rate.
  • Don’t overcrowd the pan. If you double or triple the recipe, make sure the pan is large enough or bake in batches.
  • To make them extra crispy, flip the cubes halfway through and broil for the last minute or two of cooking time.

Air Fryer Directions

  1. Preheat the air fryer to 400°F.
  2. Working in batches, air fry for 6-8 minutes, flip, and fry for another 6-8 minutes.
  3. Do not over-crowd the air fryer basket, or the potatoes will steam instead of roast.

    1. Kristyn Merkley says:

      I am glad you had them at Thanksgiving! Thank you!

  4. Margie says:

    Can I make these a day ahead

    1. Kristyn Merkley says:

      Yes, though I personally like them straight from the oven/fresh. This is my make ahead instructions…Just store in an air-tight container in the fridge for 2-3 days and reheat in the microwave or back in the oven for 10 minutes to get them crispy again.

  5. Courtney says:

    Trying later too excited!! Can I prep the sweet potatoes in the coating and let marinate for a few hours before using?

    1. Kristyn Merkley says:

      I personally haven’t, but I am sure that would still be ok 🙂 Wasn’t sure if it makes them get too soft.
