In a medium bowl, combine the softened butter, minced garlic, chopped rosemary, thyme, parsley, lemon zest, lemon juice, salt, and pepper. Mix until well blended to create the herb butter.
Pat the chicken thighs dry with paper towels. Carefully loosen the skin on each thigh with your fingers, being careful not to tear it.
Take about half of the herb butter and smear it directly under the skin of the chicken thighs, ensuring it’s evenly distributed.
Rub the remaining herb butter all over the skin of the chicken thighs, then season the outside generously with salt and pepper.
In a large roasting pan, toss the baby carrots and halved baby potatoes with a drizzle of olive oil, salt, and pepper. Arrange the chicken thighs on top of the vegetables.
Roast in the preheated oven for 35-40 minutes, or until the chicken skin is golden brown and crispy, and the internal temperature reaches 165°F (75°C).
Once done, let the chicken rest for 5-10 minutes before serving to allow the juices to redistribute.
Serve the chicken thighs over the roasted vegetables, drizzled with any pan juices for extra flavor.
Notes
Let the chicken rest before serving for better flavor.
