Recipe Information
Ingredients
- 2 tablespoons butter
- 1 medium (finely chopped) yellow onion
- 3 cloves (minced) garlic
- 4 cups chicken or vegetable broth
- 3 cups leftover mashed potatoes
- 1 cup heavy cream
- 1 cup shredded cheddar cheese
- 0.5 teaspoon (or to taste) salt
- 0.25 teaspoon (or to taste) black pepper
- 0.25 cup (for garnish) chopped green onions

Instructions
Heat a large pot over medium heat and melt the butter.
Add the chopped onion and cook for 3-5 minutes, stirring occasionally, until it becomes translucent.
Stir in the minced garlic and cook for an additional 1-2 minutes, until fragrant.
Pour in the chicken or vegetable broth and bring the mixture to a gentle simmer.
Stir in the leftover mashed potatoes, breaking them up with a spoon, and whisk until smooth and fully incorporated with the broth.
Reduce the heat to low and let the soup simmer for 10-15 minutes, stirring occasionally.
Add the heavy cream and shredded cheddar cheese to the pot. Stir until the cheese is fully melted and the soup is creamy.
Season with salt and black pepper to taste. Adjust the consistency by adding a bit more broth if the soup is too thick.
