Course Main course/ Soup
Cuisine American


  • 12 ounces bacon
  • 1 cup diced onions
  • 1 tablespoon minced garlic
  • 4-5 cups leftover mashed potatoes
  • 2 bay leaves
  • 1/2 teaspoon salt
  • 1 teaspoon pepper
  • 6 cups chicken broth preferably homemade
  • 2 cups shredded cheddar cheese plus additional for serving
  • 1/2 cup sour cream plus additional for serving
  • 1/2 cup thinly sliced green onions plus additional for serving


  • In a large soup pot over medium heat, cook the bacon until it is crispy. Transfer to a paper towel to dry. Drain the pot of the bacon fat leaving 2 tablespoons or so. Crumble the bacon and set aside.
  • Add the onion and the garlic to the pot and cook until it becomes translucent about 5 minutes.
  • Add the mashed potatoes, salt, pepper, and bay leaves. Whisk in the chicken broth and simmer over low heat for 20-30 minutes.
  • Remove from heat and add the cheese, sour cream, 1 cup of the reserved bacon, and green onions. Whisk until combined and the cheese melts.
  • Serve immediately with reserved bacon, cheese, sour cream, and green onions.


Tip! If you don't have leftover mashed potatoes, your grocery store deli always sells it over by the roasted chickens!
