Clean and cut the sweet potatoes into ½-inch thick rounds. You may keep the skin on or peel them according to your preference.

Set your oven to 380°F (200°C).

In a bowl or large ziplock bag, combine melted butter, 1 teaspoon cinnamon, salt, pepper, and paprika with the sweet potato slices. Mix thoroughly.

Place the sweet potato slices in a single layer on a baking tray.

Bake for 20-25 minutes at 380°F (200°C), until the slices are firm yet tender.

While the sweet potatoes roast, combine the maple syrup, chopped pecans, remaining 0.5 teaspoons cinnamon, and thyme in a bowl.

Remove the sweet potatoes from the oven and spoon about 1 teaspoon of the maple pecan mixture onto each slice. Return the tray to the oven and bake for an additional 8-10 minutes.

Serve the roasted sweet potatoes as they are, or garnish with crumbled feta cheese if desired.
