Preheat the oven to 400°F (200°C).
Scrub the russet potato thoroughly, pierce it several times with a fork, and place it directly on the oven rack to bake for 45 to 50 minutes until the center is soft.
In a small bowl, mash 1 teaspoon of ghee with the minced garlic, dried rosemary, dried thyme, sea salt, and black pepper to create an herb paste.
Pat the turkey breast dry with a paper towel and rub the herb paste evenly over all sides of the meat.
Place the seasoned turkey in a small roasting pan or oven-safe skillet and roast for 25 to 30 minutes, or until the internal temperature reaches 165°F (74°C).
While the turkey rests for 5 minutes, steam the green beans over boiling water for about 6 minutes until they are vibrant and crisp-tender.
Slice the turkey breast against the grain and serve alongside the split baked potato topped with the remaining teaspoon of ghee and the steamed green beans.
