Heat the oven to 350°. Place the turkey skin-side down on a cutting board and season with salt, pepper, garlic, and thyme.
Beginning at an end, roll a thigh lengthwise into a cylinder. Tie it firmly every two inches with kitchen twine. Season the skin with salt and pepper. Repeat with the other thighs.
Heat the oil in a large nonstick, oven-safe skillet over medium heat. Sear the turkey until lightly browned on all sides, about 3 to 4 minutes.
Bake the thighs until they're no longer pink on the inside, about 20 minutes. Let the meat cool, remove the twine, and cut the turkey into 1/2-inch slices.
