how to make Roasted Sweet Potatoes with Garlic and Parmesan

Ingredients

2 pounds (about 900 g) sweet potatoes, peeled and cut into 1-inch cubes
3 tablespoons olive oil
3 cloves garlic, finely minced
1 teaspoon fine sea salt (or to taste)
1/2 teaspoon freshly ground black pepper
1/2 teaspoon smoked paprika (optional, for a smoky note)
1/2 teaspoon dried thyme or Italian seasoning
1/4 teaspoon red pepper flakes (optional, for a little heat)
1/2 cup freshly grated Parmesan cheese, loosely packed, plus 2 tablespoons for serving
2 tablespoons chopped fresh parsley (or chives) for garnish
Zest of 1/2 lemon (optional, for brightness)
Nonstick cooking spray or a little extra oil for the baking sheet

Directions

Preheat the oven
- Preheat your oven to 425°F (220°C).
- Line a large baking sheet with parchment paper or lightly grease it with olive oil or nonstick spray. Make sure the pan is large enough to keep the sweet potatoes in a single layer for the best browning.
Prepare the sweet potatoes
- Peel the sweet potatoes and cut them into even 1-inch cubes. Keeping the pieces uniform helps them cook evenly.
- Place the cubes into a large mixing bowl.
Season the potatoes
- Drizzle the sweet potatoes with 3 tablespoons of olive oil.
- Add the minced garlic, salt, black pepper, smoked paprika (if using), dried thyme or Italian seasoning, and red pepper flakes (if using).
- Toss thoroughly with your hands or a large spoon until every cube is lightly coated with oil and seasonings.
Arrange on the baking sheet
- Spread the seasoned sweet potato cubes onto the prepared baking sheet in a single layer. Avoid crowding them to help them roast and caramelize.
Start roasting
- Place the baking sheet on the middle rack of the preheated oven. Roast for 15 minutes without stirring to allow a good crust to form.
Flip and continue roasting
- After 15 minutes, remove the tray and flip the sweet potatoes using a spatula. Make sure fresh sides touch the pan.
- Return the tray to the oven and roast for another 10 to 15 minutes, until tender when pierced with a fork and browned on the edges.
Add Parmesan and finish roasting
- Take the tray out of the oven and sprinkle the 1/2 cup of grated Parmesan evenly over the hot sweet potatoes.
- Gently toss or turn the cubes so some cheese makes contact with the pan and potatoes.
- Return to the oven and roast for an additional 3 to 5 minutes, until the Parmesan melts and is lightly golden. Watch closely to avoid burning.
Add freshness and adjust seasoning
- Remove the baking sheet from the oven. If using, sprinkle lemon zest and chopped parsley over the top.
- Toss gently to distribute and taste. Add more salt or pepper if needed. For extra richness, you can sprinkle the remaining 2 tablespoons of Parmesan over the hot potatoes before serving.
Serve
- Transfer the roasted sweet potatoes to a serving platter or bowl. Serve hot as a side dish with roasted chicken, steak, fish, or as part of a vegetarian spread. Enjoy immediately while the edges are crisp and the cheese is fragrant.
