A warming bowl of soup is always welcome at the table, and this roasted garlic potato soup is as savory and nourishing as it gets. It’s hands down a simply delicious soup recipe that will cozy-up your day.

Made without cream or flour, this soup is naturally thick and hearty with a lovely smooth texture.

Ingredients in potato soup

  • Potatoes: Potatoes give this soup gives a satisfying creamy texture without needing to add heavy cream, butter or milk. The best type to use are yellow Yukon gold potatoes. Baking potato varieties such as russet potatoes have a dryer texture that aren’t great for creamy soup.
  • Garlic: Let’s talk about garlic — because delicious food wouldn’t be the same without it. The “stinking rose” not only makes most everything taste better, it’s long been credited for its remarkable healing abilities. This recipe uses a whole head of garlic, not nearly as much as some recipes that call for 50, 80 or 100 cloves (who feels like counting?) but it’s no less a distinct seasoning. Plus, while the garlic is roasting the kitchen smells absolutely amazing. Roasting garlic also tempers the its raw bite, making it mellow and almost sweet.
  • Leek: This allium pairs well with potatoes. If you don’t have one, substitute with a medium onion or a bunch of chopped green onions.
  • Cheese: I use freshly grated Parmesan. A good sharp cheddar cheese is a perfect choice to use instead.
  • Broth: I usually use vegetable broth, but chicken broth is also tasty if you don’t need the soup to be vegetarian.

When it seems like a hassle to pull the big blender out (and then clean it), I use a hand blender to puree this soup right in the pot or Dutch oven. It’s the best!

An immersion blender is the secret to the soup’s smooth texture — but any powerful blender works like magic to make potato purees airy and velvety. Just don’t use a food processor, which can cause the potatoes to become pasty.

Serving ideas

  • To enjoy this soup as meal all by itself, garnish the soup with roasted potatoes and freshly grated Parmesan cheese. Serve this hearty soup with toasted crusty sourdough bread to savor every drop.

To jazz the soup up even more:

Pro tip for peeling garlic:

  • Separate unpeeled garlic cloves from the head.
  • Put them in a bowl and cover with water.
  • Soak the cloves 15-30 minutes then drain. The skins will loosen and peel away easily.

Servings 6 servings

Ingredients

  • 1 head of garlic, separated into cloves and peeled
  • Extra-virgin olive oil
  • Kosher salt
  • 6 cups vegetable broth, or water
  • 3 pounds yellow potatoes such as Yukon Gold (peeled or unpeeled as you prefer), cut into 1½-inch dice
  • 1 leek, white and light green parts thinly sliced, or 1 medium onion, chopped
  • ½ cup freshly grated Parmesan cheese
  • 1 teaspoon fresh lemon juice
  • 2 tablespoons chopped parsley

Instructions 

Roast the garlic and potatoes

  • Heat the oven to 425 (220 C) degrees.
  • Put the garlic cloves in a small baking dish. Drizzle with olive oil, sprinkle with a pinch of salt and cover with a piece of foil. Roast until the cloves are soft and golden brown, 20-25 minutes. (The roasted garlic can be prepared up to 5 days ahead. Store in the refrigerator in a covered container).
  • Put 2 cups of the potatoes on a baking sheet. Add 2 tablespoons olive oil and ½ teaspoon salt and toss around to coat. Put them in the oven next to the garlic, and roast until tender, 25-30 minutes.

Make the soup

  • Heat a tablespoon of olive oil in a Dutch oven or large saucepan over medium-high heat. Add the leek and cook until softened. Add the roasted garlic, remaining raw potatoes, 6 cups broth and 1 teaspoon salt. Bring to a simmer and cook until the potatoes are tender, about 25 minutes.
  • Puree the soup with a hand blender or in a regular blender in batches (let it cool 10 minutes before putting in the blender) until smooth. Stir in ¼ cup of the Parmesan cheese and the lemon juice.
  • To serve, put 4 or 5 roasted potatoes in each serving bowl. Ladle the soup over the potatoes. Sprinkle with additional cheese and the parsley.

Karen’s Notes and Tips

  • The soup will keep refrigerated 3-4 days, or frozen in small containers up to one month. Cool the soup completely before freezing to avoid ice crystals from forming.
  • Pro tip for peeling garlic: Separate unpeeled garlic cloves from the head. Put them in a bowl and cover with cold water. Soak the cloves 15-30 minutes, then drain. The skins should loosen and peel away easily.

    I forgot to mention that I used three sliced scallions instead of a leek.

    I’m eating this now, with one
    addition — a tablespoon of dried dill. Delicious!

    This recipe is a great if you or your guests have trouble digesting dairy. Also, my house does not reek of garlic as some prior posts say. You’d think this would taste overwhelmingly of garlic, but it doesn’t – just perfectly earthy and full-flavored. It’s a great consistency – it is a soup! The roasted potatoes in the bottom of the bowl add a great texture and flavor. As I am used to potato soup with carrots and celery, one thing I might try next time is to roast a couple carrots along with the potatoes and since celery tends to get stringy if you cook it like that, I may add in a stalk with the immersion blended portion of the soup. You could change this up with a few mushrooms, too. I will definitely make this again, it’s delicious!

  5. Love this! Very healthy and very simple.

  6. Making this tonight for dinner along with fresh-baked sourdough bread.

  7. Potato soup is my all time favorite. I’ve never thought to add parmesan cheese on it.

  8. This soup looks so cosy and nutricious!
