These tender, extra-savory, thin-sliced Southwestern roasted sweet potatoes are a great Paleo side dish for your holiday table - or any time. Sweet potatoes roasted with olive oil, a touch of butter, garlic and the bold flavors of cumin, coriander and chile powder, garnished with cilantro.
Not only is this a delicious recipe, it’s beautiful, and very easy to put together. You could take this to any potluck gathering and impress your host and fellow guests.
The sweet potato dish is ideal for a novice cook. Once you've sliced the sweet potatoes and assembled the dish, there is no guessing about cooking it. The combination of baking the sliced, seasoned sweet potatoes covered first, then uncovered at a higher temperature, makes it a showy and tasty dish that only requires a steady hand in slicing.
Plus, I've included options for Thanksgiving or Mediterranean flavors, just by changing the seasonings.

Steps in making this dish
Preheat the oven to 375 degrees F. Measure out the herbs and spices, peel and mince the garlic, then make the seasoned butter/oil mixture.
Stir together olive oil and melted butter with minced garlic, salt and pepper, and ground cumin, coriander, chile powder and chopped cilantro. Spread a tablespoonful or so of the mixture over the bottom of a 9 x 13 inch baking dish.
Step 2. Slice and season the sweet potatoes.
Peel and slice the sweet potatoes about ¼ inch thick. Making the slices the same thickness will help them cook evenly and make a more attractive dish. Hold each sliced potato together while placing it carefully in the pan. I place the first potato in the center of the side of the pan. Then I place half the slices from the second potato pointing in the opposite direction from the first (see photo). Continue alternating placement of the sweet potatoes.
Brush the remaining butter mixture over the tops of the potatoes. Cover the pan with foil.
Step 3. Roasting
Place the covered baking dish into the oven and roast for 45 minutes. Then remove the foil, turn up the heat to 450 degrees F and roast the uncovered potatoes for 15 more minutes (20-25 minutes at high altitude).
If the sweet potatoes have dried out during the last roasting, brush the tops with a small amount of olive oil just before serving. Enjoy this great side dish!
What can I serve this side dish with?
The roasted sweet potatoes are wonderful with Dutch oven Carne Asada and a green vegetable.
They are also a perfect non-sugary Thanksgiving side dish, especially with the substitution of pumpkin pie spice for the cumin, coriander and chile powder. We will be enjoying them with caramelized Brussels sprouts, Instant Pot salt potatoes, cranberry sauce with apples, and our roasted turkey.
What other seasonings are good on these sweet potatoes?
As I noted above, to harmonize this dish with your Thanksgiving dishes, use pumpkin pie spice instead of the cumin/coriander mixture. The sweet potatoes will have plenty of flavor without adding sugar. However, if your family is used to a sweet" sweet potato dish, stir in ¼ cup coconut sugar into the sauce before using it for basting.
As a Middle-Eastern variation on the Southwestern seasonings, substitute berbere seasoning, leaving everything else the same. So fragrant!
