Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Pat the turkey breast completely dry with paper towels to ensure a crisp exterior.
In a small bowl, whisk together the olive oil, dried sage, dried thyme, sea salt, and black pepper.
Rub the herb oil mixture evenly over all sides of the turkey breast.
Place the turkey breast and the sliced carrots on the prepared baking sheet, tossing the carrots in any excess herb oil.
Roast for 25 to 30 minutes, or until the internal temperature of the turkey reaches 165°F.
Remove the turkey from the oven and let it rest on a cutting board for 5 minutes before slicing.
While the meat rests, pour the chicken broth into a small saucepan and whisk in the arrowroot starch until dissolved.
Bring the broth to a simmer over medium heat, whisking constantly until the gravy thickens and becomes glossy.
Slice the turkey and serve immediately with the roasted carrots and a generous drizzle of the warm pan gravy.
