Peel the skin of sweet potatoes, cut into small to medium cubes.
On a greased baking pan, toss the sweet potato cubes evenly in neutral cooking oil.
Place the sweet potato in the oven top rack. Roast for 12 - 15 minutes and flip them halfway to ensure they get crispy on all sides.
Make the Maple Miso glaze while the sweet potatoes are cooking in the oven.
Handle the hot sweet potatoes carefuly (let them cool for 5 minutes if needed) then toss the gently with the miso glaze. Use more or less of the glaze depending on your preference.
Place the glazed sweet potatoes back on the baking sheet. Roast for another 5 minutes.
Garnish with sesame seeds before serving.
Notes
Overcook the sweet potatoes can result in mushy sweet potatoes.
