Unpretentious Cooking: Harissa-Spiced Sweet Potatoes with Whipped Tahini Sauce
Warm spices and cool yogurt amp up the flavor of North Carolina’s beloved crop
by Chef Matthew Krenz
I absolutely love pairing warm spices with sweet potatoes this time of year. It is a step away from the old standby of dumping brown sugar and cinnamon on them (not that there is anything wrong with that!). I find that roasting and concentrating the sweetness and meatiness of the potatoes adds to the allure of this side dish, and giving it a little kick and coolness rounds out the flavors to be new and exciting for friendly potlucks and gatherings. I hope you enjoy this (last) wintertime dish, as spring is already showing that it is nearby. Cheers!
Whipped Tahini Sauce
Makes 16 oz.
1 lb. plain greek yogurt
¼ c. tahini paste
1 tbsp. garlic, finely minced
2 tbsp. ginger, finely minced
2 tbsp. pomegranate molasses
1 tbsp. ground sumac
2 tbsp. orange zest
3 oz. fresh orange juice
1 oz. fresh lime juice
2 oz. extra virgin olive oil
Salt, to taste
- In a stand mixer, combine all ingredients except the olive oil and salt. Using the whisk attachment, whip the ingredients until fluffy and pale, adding in the olive oil while mixing a little at a time. Season to taste and set aside.
Harissa Spice Roasted Sweet Potatoes
Serves 4-6
2 tbsp. avocado oil
1 tbsp. olive oil
4-5 medium sweet potatoes, peeled and sliced into uniform wedges
2-3 tbsp. harissa spice blend (more if you want it spicier)
2 tbsp. ghee
1 tbsp. garlic, finely minced
Salt to taste
- Preheat oven to 375°F.
- Brush a roasting pan with avocado oil.
- In a large bowl, toss sweet potatoes with olive oil, salt, and harissa spice.
- Place the coated sweet potatoes on the roasting pan and roast until cooked through and lightly caramelized around the edges, about 20-30 minutes, flipping halfway through.
- Place the ghee, garlic, and extra harissa as desired to a mixing bowl and stir to combine.
- Toss the sweet potatoes with the ghee mixture until fragrant and evenly coated.
- Spread the yogurt mixture on a plate, then top with sweet potatoes. Serve immediately.
