Potato Leek Soup with Orzo

This is a thick, creamy soup that gets its texture from blended potatoes – no cream or milk needed. The orzo makes it hearty enough to be a main dish.

Ingredients (~6 servings)

  • 3 large leeks
  • 2 Tbsp olive oil (for sautéing)
  • 1 medium onion, diced
  • 5 cloves garlic, pressed or minced
  • 6 cups vegetable or chicken broth
  • 1 lb yellow potatoes, peeled and cut into ~3/4″ cubes
  • 1 1/4 tsp salt (or to taste)
  • 3/4 tsp ground black pepper (or to taste)
  • 3/4 cup dry orzo pasta
  • Chopped parsley for garnish

Prep the Leeks

Cut off and discard the dark green tops and the root ends; keep the white and light green parts.

Cut each leek in half lengthwise, then with the cut side down, slice into thin strips.

Put the 3 leeks in a large bowl and fill with cold water. Break up the slices with your hands and slosh them around – this gets all the dirt out from between the layers.

Lift the leek pieces out with your hands or a strainer and pat dry.

Sauté the Aromatics

Add 2 Tbsp of olive oil to a large soup pot over medium heat.

Add the 3 prepped leeks and sauté for ~5 minutes, stirring occasionally.

Add the diced onion and sauté for ~3-4 minutes until the onion becomes slightly golden.

Add the 5 cloves of garlic and sauté for 2 more minutes.

Simmer the Potatoes

Pour in the 6 cups of broth and raise the heat to medium-high.

Stir in the 1 lb of cubed potatoes.

Once the soup reaches a boil, lower the heat and simmer for ~20-25 minutes until the potatoes are fork-tender.

Blend Until Creamy

Use an immersion blender to blend the soup until creamy.

If you don’t have an immersion blender, carefully transfer batches to a regular blender, then return the blended soup to the pot over medium heat.

The potatoes create the creamy texture here – that’s why no dairy is needed.

Add Orzo and Finish

Once the soup is blended, add the 1 1/4 tsp salt and 3/4 tsp black pepper; adjust to taste.

Add the 3/4 cup of orzo and cook for ~10-11 minutes, stirring occasionally, until the orzo is tender.

The orzo will absorb some of the liquid as it cooks.

Serve with chopped parsley on top.
