Leftover Mashed Potato Soup Recipe
This leftover mashed potato soup recipe is easy to whip up and can be adapted to fit your taste. It’s like transforming your leftover mashed potatoes into a luxurious, velvety bowl of comfort. Let’s dive into how to make it:
Ingredients Needed
- 2 cups of leftover mashed potatoes (the star of the show)
- 2 tablespoons of butter (for richness and flavor)
- 1 medium onion, finely chopped (for a slight sweetness and savory base)
- 2 cloves garlic, minced (to add a fragrant depth)
- 4 cups chicken or vegetable broth (for a flavorful, liquid base)
- 1 cup milk (for extra creaminess)
- 1 cup shredded cheese (cheddar is popular, but any meltable cheese works)
- 1 teaspoon dried thyme (for an earthy, herby note)
- Salt and pepper to taste (for seasoning)
- Fresh parsley or chives, chopped (for garnish, adding color and freshness)
- Optional toppings: crumbled bacon, sour cream, or green onions (these elevate the soup even more)
Cooking Instructions
- Prepare your base: In a large pot, melt the butter over medium heat. Add the chopped onions and cook for 3-4 minutes, or until softened. You want them to become translucent and a little golden to bring out their natural sweetness. Add the garlic and cook for another 1 minute, making sure it doesn’t burn.
- Mix the broth and potatoes: Pour in the chicken or vegetable broth and bring to a simmer. Then, whisk in your leftover mashed potatoes. If your mashed potatoes are a little thicker than you’d like, add some extra milk or broth to loosen it up.
- Simmer and blend: Stir everything together until the mashed potatoes start to break down into the soup base. Let it simmer for about 5-10 minutes, stirring occasionally. If you want a smoother texture, use an immersion blender or transfer the soup to a regular blender. Blend until you get the consistency you like. For a chunkier soup, blend just half.
- Add creaminess: Pour in the milk and stir until well combined. You can adjust the amount of milk depending on how creamy or thick you like your soup.
- Add the cheese and seasoning: Stir in the shredded cheese until melted and fully incorporated. Season with thyme, salt, and pepper to taste.
- Serve and garnish: Ladle the soup into bowls and garnish with fresh parsley or chives. If you’re feeling extra indulgent, top with some crumbled bacon, a dollop of sour cream, or a sprinkle of green onions. Serve hot and enjoy!
Ingredient Insights
- Mashed Potatoes: The texture of mashed potatoes forms the backbone of the soup, making it rich and hearty. If your mashed potatoes are already seasoned, be mindful of how much extra salt and pepper you add to the soup.
- Butter and Onion: A classic flavor combination. The butter adds richness, and the onions provide a sweet, aromatic foundation for the soup.
- Broth: Using chicken or vegetable broth infuses the soup with extra flavor. You can make your own or use a store-bought option. The broth also thins out the mashed potatoes, turning them into a soup-like consistency.
- Milk: This adds the necessary creaminess to balance the potatoes. You can substitute with cream for an even richer texture, or use plant-based milk for a dairy-free version.
- Cheese: Cheddar cheese is a popular choice, but other cheeses like mozzarella, gouda, or even cream cheese can be used to add a unique twist.
- Thyme: A savory herb that complements potatoes very well. It adds a subtle earthiness to the soup that brings everything together.
Expert Tips
- Use leftover mashed potatoes: This recipe is perfect for those extra mashed potatoes that you have hanging around after a big meal. The flavor from the day-old mashed potatoes actually makes the soup even better, as the ingredients have had time to meld.
- Texture preference: If you like a chunky soup, don’t blend all of it. Keeping some of the mashed potatoes intact can add texture. For a smoother finish, blend everything to create a creamy, velvety texture.
- Flavor variations: If you’re craving a bit more flavor depth, a dash of hot sauce or a sprinkle of smoked paprika can give the soup a whole new level. A splash of white wine while sautéing the onions can add a nice depth of flavor, too.
- Don’t forget the toppings: The right garnish can make all the difference! Consider crumbled bacon, shredded cheese, a dollop of sour cream, or even crispy fried onions to add texture and extra flavor.
Recipe Variations
- Loaded Mashed Potato Soup: Add cooked bacon, green onions, and extra cheese to make it a loaded baked potato-inspired soup. Top with sour cream for the full effect!
- Vegan Version: Use plant-based milk (like almond or oat milk) and swap the butter for olive oil or coconut oil. Choose dairy-free cheese or skip it altogether for a lighter version.
- Spicy Mashed Potato Soup: For a little heat, add diced jalapeños or a pinch of cayenne pepper. You could also mix in some chili powder or smoked paprika for a smoky kick.
- Herbed Mashed Potato Soup: For a fresher, herby twist, add fresh herbs like rosemary, basil, or parsley during the simmering phase. This will give the soup a more vibrant, aromatic flavor.
- Cheese Lovers’ Delight: You can experiment with different types of cheese like Gouda, mozzarella, or even brie for a creamier, more sophisticated version. Mix in more than one kind for a cheesy masterpiece.
