Ingredient Notes

Leeks: we love using leeks in this recipe instead of onion, but if you can't find any leeks, yellow onion is a great substitute.
Potatoes: Yukon gold potatoes work best in puréed soup because they don't get super gummy/mealy when blended. Avoid using red or russet potatoes, which won't have quite as creamy a texture when blended.
Kale: we prefer lacinato (aka Tuscan) kale, which is a bit less fibrous and blends better than regular leafy green kale. You could also sub with spinach if desired.
Fresh herbs are best in this recipe, as they add a nice refreshing, herbaceous flavor. If you only have dried herbs, you can use 1 tablespoon each of dried parsley and basil.

This soup also tastes delicious unblended. For extra protein, you can add in a can of white beans.

Can you freeze potato kale soup?

Short answer: no, we don't suggest it. Creamy potato soup does not freeze well and can become grainy when defrosted. If you don't blend the soup, you can freeze for up to 3 months.
