Today’s Roasted Sweet Potato Cubes is one we love so much we make them almost weekly!! They’re one of our favorite side dishes and are also great in salads, burger bowls and more.
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, the entire family has fallen in love and asked that we make them regularly.
We love that they take about 5 minutes to prep and 20 minutes 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 You’ll Love Them + Why They Work:
- 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 incredible.
- The bag makes coating easy. Shaking the sweet potatoes with butter, oil, Parmesan, garlic, and seasonings helps every cube get covered.
- Cutting even cubes helps roasting. 1-inch pieces cook evenly and become soft and tender while baking.
Roasted Sweet Potato Ingredients
- Unsalted butter, melted (2 tablespoons): Adds flavor and helps the coating cling to the sweet potatoes.
- Olive oil (1 tablespoon): Helps the sweet potato cubes roast and prevents them from drying out.
- Grated Parmesan cheese (¼ cup): Adds salty, cheesy flavor to the coating and a crisp once it’s cooked.
- Minced garlic (2 teaspoons): Adds savory garlic flavor.
- Garlic salt (½ teaspoon): Seasons the sweet potatoes and adds extra garlic flavor.
- Italian seasoning (½ teaspoon): Adds flavor that pairs well with the Parmesan and garlic. Basil seasoning also works. To change the flavors, try a combination of cumin, garlic powder, chili powder, black pepper, and paprika.
- Sweet potatoes, peeled and cut into 1-inch cubes (2): Creates the sweet, tender base of the side dish.
- Dried parsley, optional: Adds color and a simple finished look before serving. We usually use chopped curly parsley for this.
How to Make Roasted Sweet Potato
PREP. Preheat the oven to 400°F. Line a baking sheet with foil and spray with nonstick cooking spray. Set aside.
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.
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.
Air Fryer Directions
- Preheat the air fryer to 400°F.
- Working in batches, air fry for 6-8 minutes, flip, and fry for another 6-8 minutes.
- Do not over-crowd the air fryer basket, or the potatoes will steam instead of roast.
Kristyn’s Recipe Tips
- Cut the sweet potatoes into even 1-inch cubes so they roast at the same rate.
- Use a large resealable bag so the coating has plenty of room to cover every piece.
- Spread the cubes in an even layer on the baking sheet so they roast instead of steam.
- Check for tenderness with a fork before removing them from the oven.
- To make them extra crispy, flip the cubes halfway through and broil for the last minute or two of cooking time.
- Make-ahead tip: peel and cube the sweet potatoes earlier in the day, then coat and roast them right before serving for the best texture.

I am confused about the amount of potatoes to use. The recipe says serves 6, and to use 2 potatoes, but in another area it says this:
Since the recipe only calls for 2 potatoes, take note of that when doubling, tripling or even quadrupling. Here is a guide to help with that knowing that 2 potatoes serves 2-3 people
2 people – 2 potatoes
5 people – 3-4 potatoes
10 people – 8 potatoes
15 people – 10-11 potatoes
20 people – 15-16 potatoes
When I go to the print version for 12 servings, it says to use 4 potatoes.
I am cooking for 8 people, and thought I’d use 12 serving measurements from the “print” version
Are the measurments accurate? It doesn’t seem to be as far as amount of potatoes
