To make the glaze, combine the root beer and stock in a medium heavy saucepan. Bring to a boil over medium-high heat. Reduce the heat to medium-low and simmer until reduced to a thick syrup, about 1 cup, about 50 minutes to 1 hour. Remove from the heat.
Preheat a grill to medium-high. Preheat the oven to 425 degrees F.
Season each chop on both sides with 1 teaspoon of the Essence. Grill for 3 minutes. Turn each chop 1/4 turn to make grill marks and cook an additional 2 minutes. Turn and cook on the second side for 5 minutes.
Transfer to a baking sheet. Drizzle 1 teaspoon of the olive oil over each chop. Roast until cooked through and an instant-read thermometer inserted into the center reaches 150 degrees F, 12 to 15 minutes.
Place the chops on 4 serving plates and drizzle with the glaze. Spoon the Bourbon-Mashed Sweet Potatoes and Caramelized Onions onto the plates, garnish with parsley leaves, and serve.
Combine all ingredients thoroughly.

Preheat the oven to 350 degrees F.
Place the potatoes on a foil-lined baking sheet. Bake until tender and starting to ooze sugary syrup, about 1 hour and 15 minutes, depending on their size. Remove from the oven and let sit until cool enough to handle.
Cut a slit down each potato and scoop the flesh into a large bowl. Discard the skins. Add the cream, bourbon, brown sugar, molasses, and salt and beat on high speed with an electric mixer until smooth. Cover to keep warm, or gently reheat before serving.
Melt the butter in a large skillet over medium-high heat. Add the onions, reduce the heat to medium-low, and cook slowly, stirring occasionally, until golden brown and caramelized, 45 minutes to 1 hour. Remove from the heat and serve hot.
