Add 4 tablespoons butter to the brown bits at the bottom of the stock pot. Add onion and continue to cook over medium heat until onion is caramelized. Add minced garlic and flour. Stir flour until absorbed by the butter and cooked, about 1-2 minutes.
04While stirring, slowly add chicken stock to the flour mixture to prevent lumps. Bring to a simmer then turn heat to low. Add the insides of the diced baked potato. Add sea salt and pepper. Cover pot and continue to cook over low heat.
05In a large saute pan add 2 tablespoons of butter and 2 tablespoons olive oil over medium-high heat and heat until all of the butter is melted. Add the chopped potato skins and fry them until crisp and heated through.
06Add 1/2 of the crumbled bacon, 2 cups of cheddar cheese, 2/3 of the scallions and Greek yogurt into the pot of soup. Stir well and continue to cook over low heat until heated through and cheese is melted.
07Serve soup topped with remaining bacon, cheedar cheese, scallions and crisp potato skins.
