Preheat your oven to 425°F and line two baking sheets with parchment paper.
Arrange sweet potato rounds in a single layer on the baking sheets, making sure they don't overlap.
Brush both sides of each round with olive oil and sprinkle with cinnamon, garlic powder, salt, and pepper.
Roast for 25-30 minutes, flipping halfway through, until the rounds are tender and lightly caramelized.
While the sweet potatoes are roasting, mix together the goat cheese, chopped cranberries, and half of the chopped pecans in a bowl.
Remove the sweet potato rounds from the oven and let them cool for about 5 minutes.
Top each round with a dollop of the cranberry-cheese mixture.
Drizzle with honey, sprinkle with remaining pecans and fresh rosemary, and garnish with thyme leaves before serving.
