Preheat your oven to 400°F and line a baking sheet with parchment paper.
Dice the potato into half-inch cubes and place them in a mixing bowl.
Mince the garlic cloves and add them to the bowl with the potatoes, along with 1 teaspoon of olive oil, rosemary, thyme, and half of the salt and pepper.
Toss the potatoes until evenly coated, then spread them in a single layer on the baking sheet.
Roast the potatoes for 25 to 30 minutes, flipping halfway through, until they are golden and crispy.
While potatoes roast, season the chicken breast with the remaining salt and pepper.
Heat the remaining teaspoon of olive oil in a skillet over medium-high heat and cook the chicken for 6 to 7 minutes per side until the internal temperature reaches 165°F.
Steam the asparagus for 3 to 5 minutes until tender-crisp and bright green.
Plate the roasted potatoes, chicken, and asparagus, finishing the dish with a generous squeeze of fresh lemon juice over the chicken and vegetables.
