Step‑by‑Step Instructions for Sheet-Pan Harissa Chicken & Sweet Potatoes
Step 1: Marinate Chicken
Begin by seasoning the chicken thighs with kosher salt and freshly ground black pepper. In a bowl, combine harissa paste, fresh lemon juice, and minced garlic, then coat the chicken thoroughly with this mixture. Allow the chicken to marinate at room temperature for 30 minutes, which will infuse it with flavor and ensure even cooking.
Step 2: Prepare Veggies
While the chicken marinates, preheat your oven to 425°F (220°C). Slice the sweet potatoes and red onion, then place them on a baking sheet. Drizzle with extra-virgin olive oil, followed by cumin seeds, salt, and pepper. Toss everything until the veggies are well coated, creating a base for your delicious Sheet-Pan Harissa Chicken & Sweet Potatoes.
Step 3: Arrange and Roast
Once your oven is preheated, nestle the marinated chicken thighs onto the baking sheet alongside the veggies. Make sure the chicken pieces are evenly spaced for optimal roasting. Place the pan in the oven and roast for about 30-35 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the sweet potatoes are tender and caramelized.
Step 4: Finish and Serve
After roasting, carefully remove the baking sheet from the oven. Garnish the dish with fresh cilantro for a burst of color and flavor, and serve with lemon wedges for added zest. Enjoy this vibrant Sheet-Pan Harissa Chicken & Sweet Potatoes right from the pan for a casual and inviting dining experience.
