Ingredients – What You Need

You’ll need 7 ingredients to make this creamy soup happen (minus salt & black pepper). See below for the full list.

Leeks: these onion-like vegetables add a lot of flavors and are sweet in taste!
Potatoes: these will add creaminess to the soup when blended! I recommend using Yukon gold potatoes.
Yellow onion: for flavor!
Garlic: fresh garlic is a must for a flavor-filled soup.
Vegetable broth: for the base of the soup! I like using low sodium vegetable broth and adjusting the salt as needed.
Oil: for sauteing the vegetables. You can use olive, avocado oil, or butter/vegan butter.
Thyme: to infuse the soup with fresh flavor while it simmers.

How to Develop the Most Flavor

Ensuring your soup has tons of flavor is always most important. When making leek soup I love to use ingredients that develop strong flavor with little effort. I recommend using yellow onion, fresh garlic, black pepper, and thyme sprigs for a sweet aroma.

Those four ingredients alone develop layers of flavor to this simple soup. Make sure to top with chives for an extra zing! And as always, salt your soup to taste until the flavor is just right before serving.

How to Make Leek and Potato Soup – Step by Step

• (1) Chop up your leeks and rinse thoroughly in a bowl of water.
• (2) Peel and prepare potatoes. Dice and then soak in cold water to remove extra starch.
• (3) In a large pot with oil sauté the leeks, onion, and garlic until soft. Then add broth, thyme sprigs, and potatoes – add pinch of salt and pepper. Simmer until potatoes are soft when tested with fork (about 15 minutes).

• (4) Either use a hand immersion blender or transfer soup to a blender and in batches.
• (5) Blend on high until creamy and smooth (no more than 20 seconds). Adjust taste with salt and pepper and enjoy!

Tips for Success

• Soak potatoes in water before using: make sure you do not skip this step. Soaking the potato pieces in cold water will remove extra starches from the potatoes which can cause an unpleasant consistency in the soup if not removed.
  If soup is too thick: if the soup consistency is too thick after blending, add more broth a little bit at a time until desired consistency. Adjust salt to taste whenever adding additional liquid.
• How to cut leeks: Leeks can be a bit confusing if you’ve never worked with them before. I love this video Ali from Gimme Some Oven created showing how to properly cut and wash leeks.
• Blending Soup: Either use a hand immersion blender to cream the soup or a high-powered blender – I used a Vitamix.

How to Freeze Soup & Keep Leftovers Fresh

Keep leftover soup fresh: let the soup cool and store in an airtight container, chill in the refrigerator for 3-4 days.

Freeze soup: make sure soup has cooled to room temperature, then add to a ziplock freezer bag to lay flat and save room, or store in an airtight container. Freeze for up to 1-3 months. When ready to serve thaw at room temperature, or in the fridge overnight, then reheat in a pot.

What to Serve it With

We love serving this soup with pizza like our naan pizza or cast iron skillet pizza! For a healthier option, we pair it with an abundant salad like our lentil salad or Tuscan artichoke salad with a side of sourdough bread.
