Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Halve the baby potatoes and trim the woody ends off the asparagus spears.
Mince the garlic cloves finely.
In a large mixing bowl, whisk together the extra virgin olive oil, fresh lemon juice, minced garlic, dried rosemary, dried thyme, sea salt, and black pepper.
Add the chicken breast, halved potatoes, asparagus, and cherry tomatoes to the bowl, tossing thoroughly until every piece is well-coated in the herb oil.
Arrange the chicken and vegetables in a single layer on the prepared baking sheet, ensuring they are not overcrowded.
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 potatoes are fork-tender and golden.
Remove from the oven and let the chicken rest for 5 minutes before slicing to keep it juicy.
