Preheat your oven to 400 degrees Fahrenheit.
Slice the carrots into rounds and the bell peppers into thin strips.
Place the chicken breast, broccoli florets, carrots, and bell peppers on a large parchment-lined sheet pan.
In a small bowl, whisk together the olive oil, minced garlic, rosemary, thyme, sea salt, and black pepper.
Drizzle the herb-infused oil over the chicken and vegetables, tossing until every piece is well-coated.
Roast in the oven for 20 to 25 minutes until the chicken is cooked through and the vegetables are tender.
Allow the chicken to rest for 5 minutes before slicing to ensure it stays juicy.
