Preheat oven to 400 degrees.
Peel the potatoes cutting the ends off flat so that each potato, when sliced in half, will stand up on its own. Then cut each potato in half. Pat the potatoes dry with paper towels.
Heat vegetable oil in a large ovenproof skillet over medium-high heat. Brown the potatoes on top and bottom. This can take about 6-7 minutes per side.
Remove the pan from the heat and add the butter, chicken stock, sliced garlic, fresh thyme, and fresh rosemary. Bake in preheated oven until the potatoes are tender. Spoon the butter mixture over the cooked potatoes and sprinkle with kosher salt and freshly ground black pepper. For best results, serve promptly.
