Turning leftover mashed potatoes into a warm, hearty soup is a fantastic way to avoid waste and enjoy a comforting dish. Loaded potato soup is beloved for its creamy texture and rich flavors, which are enhanced by simple yet flavorful ingredients. To create this loaded potato soup, start by boiling potatoes until tender if you don't already have mashed potatoes. In a pot, mix the mashed potatoes with a stick of butter and about a cup of chicken broth. The broth helps to thin out the thick mashed potatoes, creating a smooth soup consistency. Next, stir in 3 spoonfuls of cream cheese seasoned to your liking, which adds creaminess and depth to the soup. Half and half and sour cream can also be folded in to increase richness and tanginess. Chopped cooked bacon is an essential ingredient that adds a smoky and savory twist to the soup. Mix in half a cup or more depending on preference. Then, sprinkle in shredded cheddar cheese, which melts into the mixture, intensifying the savory flavor and making the soup luscious. Heat the soup on medium for about 5 minutes until everything is thoroughly warmed and the cheese has melted nicely. This loaded potato soup is not only comforting but also easy to customize. You can add seasoning such as garlic powder, onion powder, or fresh herbs like chives for an aromatic boost. Additionally, topping each serving with extra bacon bits, shredded cheese, or even a dollop of sour cream enhances the experience. Overall, this recipe is a smart way to utilize thick mashed potatoes and turn them into a delightful bowl of loaded potato soup that satisfies cravings and warms the soul.
