Preheat your oven 350 degrees f.
Heat the oil in a medium skillet, over medium-high heat. Add the onion and saute until it softens, about 3 minutes, then add garlic and saute another minute or two.
Meanwhile, in a small bowl whisk together coconut milk, paprika, and gluten-free flour.
Pour the coconut mixture over the onions in the pan, then whisk to combine.
Lower the heat to a simmer and cook stirring frequently, until the sauce begins to thicken about 2-3 minutes.
Pour the coconut sauce in the bottom of an 8 x 8 oven dish, then layer the sweet potato slices on as shown.
Cover with foil and bake for 60 minutes in your preheated oven.
Then, uncover the dish, bake for an additional 12-15 minutes, until the potatoes are fork tender and golden-crispy-browned on top.
Garnish with fresh chopped chives, and serve.
