Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Chop the broccoli into florets, slice the carrots and bell peppers into strips, and core the apple before slicing it into thin wedges.
Place the chicken breast on the prepared baking sheet along with the broccoli, carrots, bell peppers, and apple slices.
Drizzle the olive oil over the chicken and produce, then sprinkle evenly with minced garlic, rosemary, thyme, sea salt, and black pepper.
Use your hands to toss the ingredients until everything is thoroughly coated in the oil and herb mixture.
Spread the ingredients into a single layer, ensuring the chicken is not covered by the vegetables to allow for even browning.
Roast for 20 to 25 minutes, or until the chicken is cooked through and the vegetables are tender and slightly charred.
Let the chicken rest for 5 minutes before slicing to keep it juicy, then serve immediately with the roasted vegetables.
