Preheat your oven to 425°F (220°C) and line a large sheet pan with parchment paper for easy cleanup.
In a small bowl, whisk together the olive oil, lemon zest, lemon juice, minced garlic, rosemary, thyme, salt, and pepper. This will create a flavorful herb marinade.
Place the chicken thighs on one side of the sheet pan. Using a brush or your hands, generously coat the chicken with the herb marinade, making sure to get under the skin for maximum flavor.
On the other side of the pan, arrange the halved baby potatoes, sliced bell pepper, and red onion wedges. Drizzle the remaining marinade over the vegetables and toss to coat evenly.
Bake in the preheated oven for 35-40 minutes or until the chicken reaches an internal temperature of 165°F (74°C) and the potatoes are tender and golden brown. You can broil on high for an additional 2-3 minutes for extra crispiness on the chicken skin.
Once cooked, remove the sheet pan from the oven and let it rest for 5 minutes before serving.
Notes
For extra crispiness, broil the chicken for 2-3 minutes after baking.
