PREHEAT the oven to 400°F.
PIERCE each potato 5-6 times with a fork. Drizzle with olive oil and sprinkle with salt. Bake for 45-60 minutes until the potato can be pierced easily with a fork. Let potatoes cool enough to handle then slice potatoes in half lengthwise and scoop out the insides, leaving about a ¼-inch shell.
RETURN potato shells to the oven and bake for 10 minutes.
MASH potato with butter, milk, sour cream, and spices, adding additional milk if needed to reach a creamy consistency. Fold in half of the bacon and cheese. Spoon mashed potatoes back into the potato skins.
