  • 3 tablespoons olive oil
  • 3 cloves garlic, minced

Recipe Details

Prep Time: 10 minutesCook Time: 30 minutesTotal Time: 40 minutesServing Size: Serves 4

Instructions

  1. Preheat your oven to 425 degrees Fahrenheit. Line a large baking sheet with parchment paper or lightly grease it with oil to prevent sticking.
  2. In a large mixing bowl, toss the cubed sweet potatoes with olive oil, garlic, salt, pepper, and smoked paprika until evenly coated.
  3. Spread the sweet potatoes out in a single layer on the prepared baking sheet. Make sure there’s a little space between each cube—this helps them roast instead of steam.
  4. Roast for 25 minutes, stirring halfway through, until the sweet potatoes are golden and tender.
  5. Sprinkle the Parmesan cheese evenly over the sweet potatoes, then return the pan to the oven for 5 more minutes, or until the cheese is melted and lightly browned.
  6. Remove from the oven and let cool slightly. Garnish with chopped parsley if desired. Serve hot.

Tips for the Best Roasted Sweet Potatoes

  • Use parchment paper or a preheated pan: This ensures the potatoes don’t stick and get that perfectly crispy texture.
  • Don’t overcrowd the pan: Give the sweet potato cubes room to breathe. If they’re piled on top of each other, they’ll steam and turn mushy.
  • Toss well: Make sure every cube is evenly coated in oil and seasoning. A good toss in a large bowl does the trick.
  • Fresh garlic vs. garlic powder: Fresh minced garlic gives a punchier flavor, but if you’re in a rush, 1/2 teaspoon of garlic powder works just fine.

Recipe Variations

Looking to switch things up? Here are a few delicious twists on the classic:

  • Spicy Version: Add 1/4 teaspoon cayenne pepper or a dash of chili flakes for a kick.
  • Herby Roasted Potatoes: Toss in some dried rosemary, thyme, or Italian seasoning for an herby aroma.
  • Vegan Friendly: Swap out the Parmesan for a vegan cheese alternative or skip it entirely and drizzle with tahini for a creamy finish.
  • Add Protein: Mix in some roasted chickpeas or top with a fried egg for a satisfying, protein-packed meal.

Frequently Asked Questions

Can I use pre-cut sweet potatoes?
Absolutely. Pre-cut sweet potatoes save time and work just as well. Just be sure they’re evenly sized so they roast evenly.

Do I need to peel the sweet potatoes?
Peeling is optional. If you like a more rustic texture and extra fiber, go ahead and leave the skin on—just scrub them clean.

Can I make these ahead of time?
Yes, you can roast them ahead and reheat in the oven at 375 degrees for 10 to 15 minutes. They won’t be quite as crispy, but the flavor still shines through.

What kind of Parmesan should I use?
Freshly grated Parmesan is best for texture and melt, but pre-grated from the store will work in a pinch. Just avoid the powdered kind in a can—trust me, it’s not the same.

Can I make this in an air fryer?
You bet. Just reduce the cooking time to about 18 to 20 minutes at 400 degrees, shaking halfway through. Add the Parmesan in the last 2 to 3 minutes to avoid burning.

Final Thoughts

This roasted sweet potato dish has quickly become one of my go-to sides. It’s simple enough for a busy weeknight but elevated enough to bring to a potluck or serve at a family gathering. The natural sweetness of the potato plays beautifully with the savory garlic and nutty Parmesan. Add a sprinkle of parsley, and you’ve got a dish that looks as good as it tastes. Give it a try, and don’t be surprised if your family starts requesting it weekly.
