Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Halve the baby potatoes and toss them with 0.5 tbsp of olive oil, half the salt, and half the pepper.
Spread potatoes on the baking sheet and roast for 15 minutes.
Trim the woody ends off the asparagus and add them to the baking sheet with the potatoes, roasting for an additional 10-12 minutes until tender.
Season the chicken breast evenly with the remaining salt, pepper, rosemary, and thyme.
Heat the remaining 0.5 tbsp of olive oil in a large skillet over medium-high heat.
Place the chicken in the skillet and sear for 6-7 minutes per side until the exterior is golden and the internal temperature reaches 165°F.
During the last 2 minutes of cooking, add the minced garlic and fresh lemon juice to the pan, basting the chicken with the pan juices.
Plate the chicken alongside the roasted asparagus and potatoes, drizzling any remaining lemon-garlic pan sauce over the top.
