Preheat your oven to 400°F.
Start by preparing the sweet potato. Wash and prick it with a fork a few times, then place it on a baking sheet.
In a bowl, chop the red bell pepper and zucchini into bite-sized pieces. Toss them with olive oil, fresh rosemary, fresh thyme, minced garlic, salt, and pepper.
Spread the seasoned vegetables on another baking sheet in a single layer.
Place both the sweet potato and the vegetable tray in the oven. Bake the sweet potato for about 35-40 minutes until tender, and roast the vegetables for 20-25 minutes until lightly caramelized.
While the vegetables and sweet potato are baking, season the chicken thighs with salt and pepper.
Heat a skillet over medium-high heat. Sear the chicken thighs skin-side down (if applicable) for about 3-4 minutes until a golden crust forms, then flip and cook for another 3 minutes.
Transfer the seared chicken thighs to the oven on a separate tray and roast for an additional 10 minutes until the internal temperature reaches 165°F.
Once everything is cooked, plate the chicken thighs alongside the roasted vegetables and baked sweet potato. Serve warm and enjoy your balanced, nutrient-packed dinner.
