Pat the chicken thighs dry with paper towels. Season both sides generously with salt and pepper.
In a small bowl, combine minced garlic, olive oil, rosemary, thyme, and parsley. Mix well until it forms a paste.
Rub half of the herb mixture all over the chicken thighs, making sure to get it under the skin for maximum flavor.
In a large bowl, combine the halved baby potatoes, sliced carrots, and red onion wedges. Drizzle with the remaining herb mixture, season with salt and pepper, and toss until the veggies are well coated.
In a large baking dish or sheet pan, place the seasoned chicken thighs skin-side up. Surround them with the prepared vegetables, spreading them out evenly.
Roast in the preheated oven for about 35-40 minutes, or until the chicken is golden brown and the internal temperature reaches 165°F (75°C), and the veggies are tender.
Remove from the oven and let the chicken rest for 5 minutes. Serve with lemon wedges on the side for squeezing over the chicken and veggies.
Notes
Let the chicken rest before serving for better flavor.
