Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper.
Halve the baby potatoes and trim the woody ends off the asparagus spears.
In a small glass bowl, whisk together the extra virgin olive oil, lemon juice, minced garlic, chopped rosemary, thyme, sea salt, and black pepper.
Place the chicken breast, halved baby potatoes, and cherry tomatoes onto the prepared sheet pan.
Drizzle half of the lemon-herb oil over the chicken and potatoes, tossing the potatoes to ensure they are well-coated.
Roast in the center of the oven for 15 minutes.
Remove the pan and add the asparagus to the empty spaces, drizzling the remaining herb oil over the spears.
Return the pan to the oven and roast for another 10 to 12 minutes until the chicken reaches an internal temperature of 165°F and the potatoes are golden.
Let the chicken rest for 5 minutes before slicing to ensure maximum juiciness.
