Instructions

Step 1: Preheat oven to 400°F (200°C). Season chicken thighs with salt and pepper. In a bowl, mix rosemary, thyme, garlic, and olive oil. Rub the herb mixture evenly over the chicken.
Step 2: Place chicken on a baking sheet lined with parchment paper. Roast for 25-30 minutes, until the skin is golden and crispy, and the chicken is fully cooked (internal temperature 165°F/75°C).
Step 3: While chicken roasts, peel and cube potatoes. In a large pot, boil potatoes in salted water for 15 minutes, until tender. Drain and return to the pot.
Step 4: Add butter, milk, salt, and pepper to the potatoes. Mash until smooth and creamy, adjusting milk for desired consistency.
Step 5: Serve chicken with mashed potatoes, garnished with additional rosemary and thyme.
