Preheat the oven to 425°F.

Line a large baking sheet with parchment paper.

Cut the sweet potatoes into wedges about 3/4 inch thick.

Place the sweet potatoes in a large mixing bowl. Drizzle with olive oil, and sprinkle with the salt and pepper. Use a rubber spatula to toss the sweet potatoes until they are evenly coated.

Transfer the sweet potatoes to the prepared baking sheet with as much space between the wedges as possible.

Finely mince the garlic.

Roast the sweet potatoes on middle rack of oven for 12 minutes.

Carefully flip the sweet potatoes and sprinkle evenly with the minced garlic. Continue roasting until the sweet potatoes are tender and slightly charred, 10-14 minutes.

Check to see that sweet potatoes are done. Remove from oven or add time as needed.

Serve immediately.
