Preheat 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 bowl, whisk together the olive oil, lemon juice, lemon zest, minced garlic, rosemary, and thyme.
Place the chicken breast, potatoes, asparagus, and cherry tomatoes on the prepared sheet pan.
Drizzle the lemon-herb mixture over the chicken and vegetables, then season with sea salt and black pepper.
Toss the vegetables and coat the chicken thoroughly to ensure even roasting and flavor distribution.
Roast for 20 to 25 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 keep it juicy, then serve with the roasted vegetables.
