Ingredients

Instructions

  1. Step 1: Whisk 1/4 cup plain yogurt and 1/4 cup harissa paste in a bowl until smooth. Season 1.5 lbs bone-in chicken thighs with 1/2 tsp kosher salt and 1/4 tsp black pepper, then rub the marinade evenly over all sides. Let sit at room temperature for 30 minutes.
  2. Step 2: Preheat oven to 400°F. Toss 2 medium peeled and cubed sweet potatoes with 2 tbsp olive oil, 1 tsp dried oregano, 1/2 tsp kosher salt, and 1/4 tsp black pepper until coated. Spread in a single layer on a parchment-lined baking sheet.
  3. Step 3: Place marinated chicken thighs skin-side up on the baking sheet with the sweet potatoes. Roast for 25–30 minutes, or until chicken reaches 165°F internally and sweet potatoes are golden and tender when pierced with a fork.
  4. Step 4: Transfer to a platter, discarding excess pan juices. Garnish with fresh cilantro and serve immediately.
