Yes, I just said lettuce soup. Hear me out, because it turns out Lettuce Soup is light, refreshing, and incredibly healthy (which I must say feels really good after all those holiday desserts). Plus, it’s a great way to use up a big package of romaine when you just can’t fathom another salad.

What Kind Of Lettuce Is Used In Soup?
In French cuisine, the outer leaves of lettuce that are too tough for salads are used to make this soup. I’m all for less waste, so I’m here for that.
While any type of lettuce will work, the most common tend to be romaine and butter lettuce. For lettuce soup, this is paired with simple, flavorful additions like leeks, scallions, onions, garlic, herbs, or some combination of all.
Making Lettuce Soup
After the ingredients are cooked and softened, the soup is then blended to create a surprisingly creamy texture. An immersion blender is super helpful here. I was honestly shocked by this since I hadn’t added even a drop of milk or cream yet.
This recipe follows the classic process and features crisp romaine, leeks, parsley, and garlic, with a touch of dried coriander. While some recipes use water as the base, I opted for chicken broth to maximize the flavor.
As I said before, the soup is very creamy on its own, but some recipes still call for a splash of milk or heavy cream. More creaminess is never a bad thing, am I right? I opted for a few tablespoons of Greek yogurt to create that amazing silky texture while adding a subtle tangy flavor. You’ll be left in awe of just how good lettuce in soup can be—seriously.
