Instructions

  1. Step 1: In a bowl, combine 3 tbsp olive oil, 2 tbsp chopped fresh rosemary, 1 tbsp chopped fresh thyme, and 3 minced garlic cloves. Add 4 chicken breasts and coat thoroughly. Marinate for at least 30 minutes at room temperature.
  2. Step 2: Preheat oven to 425°F. Toss 3 chopped carrots, 2 chopped parsnips, and 2 cubed sweet potatoes with 1/2 tsp sea salt and 1/4 tsp black pepper on a baking sheet. Roast for 30-35 minutes, stirring halfway, until tender and caramelized.
  3. Step 3: Heat a large skillet over medium-high heat. Remove chicken breasts from marinade, seasoning with 1/2 tsp sea salt and 1/4 tsp black pepper. Sear chicken in the skillet for 5-6 minutes per side until golden brown and internal temperature reaches 165°F.
  4. Step 4: Rest chicken 5 minutes before slicing. Serve chicken alongside the roasted root vegetables, drizzling any pan juices over the top.
