Preheat your oven to 425°F (220°C).
Wash the baby potatoes and cut them into halves or quarters, depending on their size. Place them in a mixing bowl.
Drizzle 2 teaspoons of olive oil over the potatoes, season with a pinch of salt and pepper, and toss to evenly coat.
Spread the potatoes on a baking sheet in a single layer and roast in the oven for about 25-30 minutes until they are golden and crispy, turning once halfway through.
While the potatoes are roasting, pat the chicken breast dry with a paper towel. Season both sides with salt and pepper.
In a small bowl, combine minced garlic, chopped rosemary and thyme leaves (from the sprigs), and a squeeze of lemon juice.
Rub the herb mixture evenly over the chicken breast.
Heat a skillet over medium-high heat and sear the chicken breast for about 2-3 minutes per side until a golden crust forms.
Transfer the seared chicken to an oven-safe dish and place it in the oven for an additional 10-12 minutes until fully cooked.
Once the chicken reaches an internal temperature of at least 165°F (74°C), remove it from the oven.
Plate the chicken alongside the crispy lemon potatoes and finish with an extra drizzle of fresh lemon juice if desired.
