- 1 medium onion, chopped

How to Make Best Potato Leek Soup Directions
Getting started on your potato leek soup is straightforward and doesn’t demand advanced cooking skills. Here’s how you can whip up a batch that is sure to satisfy:
- Begin by cleaning your leeks thoroughly under cold running water to remove any grit. Slice them thinly and discard the tough green tops for a sweeter flavor.
- In a large pot, melt the unsalted butter over medium heat. Add the sliced leeks and the chopped onion. Sauté these ingredients together until they soften, which should take about 5 to 7 minutes. You’ll start to notice the sweet, earthy aroma filling your kitchen.
- Now, it’s time to add your diced russet potatoes. Stir them in and let them mingle with the leeks and onions for an additional minute, ensuring everything is evenly coated in butter.
- Pour in the vegetable or chicken broth, making sure that the potatoes and leeks are submerged completely. Season the mixture with salt, black pepper, and optional thyme. Increase the heat to bring the pot to a boil, then reduce it to a simmer. Allow it to cook until the potatoes are fork-tender, roughly 20 to 25 minutes.
- Once cooked, blend the soup until smooth. You can use an immersion blender directly in the pot or transfer it to a countertop blender. Gradually stir in the whole milk or cream to achieve the desired richness and texture.
- Heat the blended soup gently without bringing it to a boil again. Taste and adjust the seasoning if necessary, as you can always add a pinch more salt or pepper to suit your palate. When ready to serve, ladle it into bowls and garnish with fresh chives for a pop of color and flavor.

Expert Tips: Best Potato Leek Soup
