1 large sweet potato, peeled and sliced into 1/4-inch-thick rounds, divided 2 tbsp olive oil 2 tbsp whole-wheat flour 1 cup skim milk 1/2 tsp sea salt 1 tsp fresh ground black pepper 1 tsp chile powder 1 tsp ground cumin 1 tsp red pepper flakes 1/2 cup shredded low-fat cheddar cheese

Preheat oven to 400°F.
In a 10-inch baking dish, spread half of potato slices in an even layer, overlapping slightly if needed.
In a medium skillet, heat oil on medium-high. Sprinkle in flour and whisk until combined (mixture will resemble a paste). Gradually whisk in milk until lumps smooth out and mixture begins to thicken. Add salt, black pepper, chile powder, cumin and pepper flakes; stir to combine. Add cheese and stir until completely melted, about 2 minutes. Pour three-quarters of chile-cheese sauce over potatoes. Layer remaining potatoes over top, overlapping slightly if needed. Top with remaining chile-cheese sauce.
Transfer to oven and bake for 30 to 35 minutes, uncovered, until browned and bubbly. Remove from oven and let rest for 5 minutes before serving.
