First, wash the sweet potato thoroughly as you will leave the skin on. Then slice it into quarter-inch thick wedges of equal shape and size. Start by cutting the potato in half lengthwise, then place each half down flat on the cutting board. Start from one end and slice lengthwise again into wedges, angling the knife towards the center of the potato as needed.
Heat vegetable oil and butter in a large sauté pan over medium-high heat until the butter is fully melted. Swirl it around to mix, then add the sweet potato wedges in a single layer, laying them down flat on one side. Season with a pinch of salt and cook until bottoms are lightly golden and potatoes begin to smell sweet, about 3 to 4 minutes.
Carefully flip the potato wedges, then season with a pinch of salt and cook again until the bottoms are golden and lightly caramelized, about 3 to 4 minutes more.
Next, add the maple bourbon and maple syrup. Lower heat to medium-low to avoid burning the syrup. Stir to coat the potatoes well, being careful not to dent the potatoes with your spatula, then cover the pan and cook until potatoes are tender, about 7 to 9 minutes. Turn the potatoes over once or twice during cooking so the glaze doesn't stick to the pan and burn.
Remove from heat. Use a slotted spatula to plate the potato wedges so that any excess glaze is left behind and doesn't get transferred onto the plate - you want just a thin coating of glaze on the potato wedges when you serve them. Season the potatoes with a light pinch of salt, then top with crumbled bacon and minced chives. Serve immediately.
