How to Make Garlic-Parmesan Sweet Potatoes

  1. Prepare the pan: Line the rimmed baking sheet with foil, as it will make your cleanup so much easier. Spray the foil with nonstick spray.
  2. Prepare the potatoes: Spread the ½-inch sweet potato pieces on the foil. Drizzle over the butter, season with salt and pepper, toss, and spread out.
  3. Roast: Roast for about 20 minutes. When they are about halfway cooked, take them out and sprinkle over the minced garlic and the grated Parmesan. Toss to coat.

FAQs

What makes sweet potatoes taste better?

There are a few ways to enhance the flavor of sweet potatoes. Roasting them brings out the flavor more than other methods of cooking, like boiling. The browning in the oven brings up their natural sugars. Seasoning with salt is also important to bring out the flavor and balance their sweetness. Finally, adding enhancements like garlic or Parmesan really brings the sweet potatoes to another level!

Do sweet potatoes get sweeter the longer you cook them?

Yes, sweet potatoes do get sweeter the longer you cook them. This is only true if you roast the potatoes, not if you boil them. As the potatoes roast, the sugars are drawn out and begin to caramelize, making them even more delicious if you have the time.

How do you keep garlic from burning when roasting potatoes?

Garlic cooks much faster than potatoes, so roasting them together often means that the garlic will burn. In order to prevent that, hold back from adding the garlic until the potatoes are mostly cooked. Take them out of the oven halfway through the roasting time and toss to coat with the finely minced garlic, then finish roasting.

Ingredients 

  • 2 pounds sweet potatoes (scrubbed or peeled and cut into 1 1/2 -inch cubes)
  • 2 tablespoons butter (melted)
  • Kosher salt and freshly ground pepper (to taste)
  • 2 teaspoons finely minced garlic
  • ⅓ cup finely grated Parmesan cheese

Instructions 

  • Preheat the oven to 425 F. Line a rimmed baking sheet with foil or parchment if you like, and spray with nonstick spray.
  • Place the potatoes on the baking sheet, drizzle over the butter, then sprinkle over the salt and pepper. Toss the potatoes so that they are nicely coated with the oil, spread them out in a single layer, and then place in the oven and roast for about 20 minutes.
  • Remove the tray from the oven and sprinkle over the garlic and Parmesan. Toss, spread out the potatoes again so that they are in a single layer and return them to the oven. Roast for another 10 to 15 minutes until they are tender, browned in spots, and the cheese has melted. Serve hot.

Notes

  • Remember to line the rimmed baking sheet with foil, as it will make your clean up so much easier.
  • Mince the garlic finely so it melts into the potatoes.
