Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Dice the yellow potato into 1/2-inch cubes and slice the chicken breast into even 1-inch strips.
In a small bowl, whisk together the extra virgin olive oil, minced garlic, dried rosemary, dried thyme, lemon zest, lemon juice, sea salt, and black pepper.
Place the chicken and potatoes on the prepared baking sheet and drizzle with the herb-lemon oil mixture, tossing until every piece is thoroughly coated.
Spread the ingredients in a single layer, ensuring they aren't crowded so they can crisp up properly.
Roast for 15 minutes, then remove the pan and add the asparagus spears to the sheet, tossing them in the residual oil.
Return to the oven and roast for an additional 10-12 minutes until the chicken is cooked through and the potatoes are golden brown.
Serve immediately, garnished with an extra squeeze of fresh lemon if desired.
