Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss 3 medium peeled and 1-inch chopped carrots and 2 medium peeled and 1-inch chopped parsnips with 2 tbsp olive oil, 1/2 tsp sea salt, and 1/4 tsp black pepper on a rimmed baking sheet. Roast for 25-30 minutes, stirring halfway, until caramelized and tender.
  2. Step 2: While vegetables roast, pat dry 2 boneless skinless chicken breasts (6 oz each) and season both sides with 1/2 tsp sea salt and 1/4 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat.
  3. Step 3: Add chicken breasts to the hot skillet and cook for 5-6 minutes per side, until golden brown and internal temperature reaches 165°F. Remove and rest on a plate.
  4. Step 4: Reduce heat to medium, add 2 minced garlic cloves and 4 thyme sprigs to the skillet. Sauté for 1 minute until fragrant.
  5. Step 5: Pour in 1/2 cup chicken broth and 1 tbsp fresh lemon juice, scraping browned bits from the pan with a wooden spoon. Simmer for 3-4 minutes until the sauce reduces slightly.
  6. Step 6: Stir in 1 tsp chopped fresh thyme and remaining 2 minced garlic cloves, cooking for 30 seconds.
  7. Step 7: Serve the rested chicken breasts over the roasted root vegetables, spooning the garlic-thyme sauce over the top.
