Method
Preparation
Clean and cut the sweet potatoes into ½-inch thick rounds. Preheat your oven to 200°C (400°F).
Season the Sweet Potatoes
In a mixing bowl, combine the sweet potato slices with melted butter, 1 teaspoon of cinnamon, salt, and pepper. Mix thoroughly.
Alternatively, place the ingredients in a ziplock bag, seal it, and shake to combine.
Arrange for Roasting
Lay the seasoned sweet potato slices in a single layer on a baking tray, ensuring there’s space between each slice.
Bake in the preheated oven for 25–30 minutes, checking for fork tenderness as the baking time nears completion.
Prepare the Topping
While the sweet potatoes roast, mix the maple syrup, chopped walnuts, the remaining ½ teaspoon of cinnamon, and thyme in a bowl.
Add the Topping
Remove the baking tray from the oven. Top each sweet potato slice with about 1 teaspoon of the walnut and maple mixture.
Return the tray to the oven and bake for an additional 8–10 minutes, or until the topping caramelizes and the edges of the sweet potatoes turn golden.
Serve and Enjoy
Remove the sweet potatoes from the oven and allow them to cool slightly. Serve as is, or for added flavor, sprinkle crumbled feta cheese over the top.
Notes
Cut slices to an even ½-inch thickness for uniform cooking. Don't crowd the pan. Topping can be added near the end for caramelization.
