Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Scrub the potato and carrots, then dice the potato into 1-inch cubes and slice the carrots into half-moons.
Slice the zucchini into thick rounds, then halve them if they are large to ensure even cooking with the other vegetables.
Place the chicken breast in the center of the baking sheet and surround it with the prepared potato, carrots, and zucchini.
Drizzle the garlic-infused olive oil and fresh lemon juice over the chicken and the vegetable medley.
Finely chop the fresh rosemary and thyme leaves, discarding the woody stems.
Sprinkle the chopped herbs, sea salt, and black pepper evenly over the entire tray.
Toss the vegetables with tongs to ensure they are well-coated in the oil and seasonings, and flip the chicken to coat both sides.
Roast in the center of the oven for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are golden and tender.
Remove from the oven and let the chicken rest for 5 minutes before slicing to keep it juicy, then serve immediately.
