How to Make Sunday Night Mashed Potato Soup

Step 1: Prepare the Aromatics

Start by melting butter in a large pot over medium heat, then sauté finely chopped onions and minced garlic until they become soft and fragrant—about 3 to 5 minutes. This builds a flavorful base for your soup.

Step 2: Add Broth and Heat

Pour in your chicken or vegetable broth, bringing it to a gentle simmer. This will gently infuse the aromatics and prepare the soup for the potatoes.

Step 3: Incorporate Mashed Potatoes

Slowly whisk in the mashed potatoes to prevent lumps, stirring until the soup is smooth and thickened. This step transforms simple mash into a satisfying soup base.

Step 4: Cream It Up

Stir in milk or cream to reach your desired creaminess. Heat the soup through without boiling to keep it silky and luscious.

Step 5: Season and Serve

Finish with salt, pepper, and any fresh herbs you like. Ladle into bowls and get ready to enjoy the comfort of your Sunday Night Mashed Potato Soup!
