Why Everyone Loves This Recipe

This soup is a wonderful way to give new life to leftover mashed potatoes. It’s creamy, comforting, and easy to make with ingredients you probably already have. Plus, it reduces food waste while delivering a warm, satisfying meal.

Best Cooking Tips

- Use low-sodium broth to control the saltiness of the soup.
- Add a splash of cream or milk at the end for extra richness.
- Stir frequently to prevent the soup from sticking to the bottom of the pot.

Step 1

Cook the bacon in a large skillet over medium-high heat. Turn it occasionally and cook until it’s fully cooked but not too crispy—this should take about 8 minutes. Once done, drain the bacon on paper towels, then cut each strip in half lengthwise and chop into small pieces.

Step 2

Keep about a tablespoon of the bacon drippings in the skillet and set aside another tablespoon for later. Use the drippings left in the pan to sauté the onion over medium heat until it just starts to brown, which should take around 5 to 7 minutes.

Step 3

While the onion is cooking, combine your leftover mashed potatoes, chicken broth, and half-and-half in a large pot over medium-high heat. Whisk everything together until it’s smooth and creamy. Then stir in the reserved bacon drippings along with the corn, garlic and herb seasoning, green hot pepper sauce, paprika, Worcestershire sauce, black pepper, and red hot pepper sauce.

Step 4

Add the sautéed onions and chopped bacon to the pot. Bring the soup to a boil, then lower the heat and let it simmer gently for about half an hour to let the flavors meld together.

Perfect Pairings

Serve this soup with a sprinkle of fresh herbs like chives or parsley for a burst of color and flavor. Pair it with crusty bread or a simple green salad to complete the meal.

Best Storage Tips

Store leftover soup in an airtight container in the refrigerator for up to three days. Reheat gently on the stove, adding a little broth or water if it becomes too thick. This soup can also be frozen for up to two months.
