Clean and cut sweet potatoes into 1/2-inch thick rounds (you can either keep the skin on or peel it).

Preheat the oven to 380°F / 200°C.

In a bowl or ziplock bag, add sliced sweet potatoes, melted butter, 1 teaspoon cinnamon, salt, paprika, and pepper. Mix well.

Arrange sweet potato slices on a baking tray in a single layer, leaving some space between slices. Bake for 20-25 minutes at 380°F / 200°C.

Check that the sweet potatoes are firm and tender. Baking time may vary depending on the thickness of the slices.

Meanwhile, mix maple syrup, chopped pecans, 0.5 teaspoons cinnamon, and thyme in a bowl.

Remove the baking tray from the oven and top each sweet potato slice with about 1 teaspoon of the maple pecan mixture.

Return the tray to the oven and bake for another 8-10 minutes or until the sweet potatoes appear caramelized around the edges.

Serve as it is or with some feta garnished on top.
