Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, combine 3 tbsp olive oil, 4 minced garlic cloves, 2 tbsp lemon juice, 1 tsp sea salt, 1/2 tsp black pepper, and 1 tsp dried thyme. Add 4 bone-in, skin-on chicken thighs and toss to coat evenly.
  2. Step 2: Arrange the coated chicken thighs on a baking sheet. In the same bowl, add 2 medium diced sweet potatoes and toss with any remaining marinade. Spread the sweet potatoes around the chicken on the sheet.
  3. Step 3: Roast in the oven for 35-40 minutes until chicken skin is golden and internal temperature reaches 165°F, and sweet potatoes are tender with caramelized edges.
  4. Step 4: While chicken roasts, heat a large skillet over medium heat and add 1 tbsp olive oil. Add 5 cups fresh spinach leaves and sauté for 2-3 minutes until wilted and bright green. Season with a pinch of sea salt.
  5. Step 5: Serve the roasted chicken and sweet potatoes alongside the sautéed spinach for a balanced Whole30 dinner.
