Leek and Lettuce Salad
Ingredients
Directions
Prepare the leeks
Clean and cut the leeks into pieces about 3 inches long.
Blanch and boil the leeks in salted water until done, then drain and press dry.
Chill the leeks in the refrigerator until cold.
Assemble the salad
Clean and shred the required amount of Cos lettuce.
Arrange the lettuce in a pyramid in the center of a large salad plate.
Cut the leeks in half lengthwise and arrange them endwise around the lettuce pyramid, cut side out.
Pour French salad dressing over the salad.
Garnish the base of each leek with a slice of hard boiled egg.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leeks
- Form the main body of the salad, providing a mild, tender vegetable texture.
- Cos lettuce
- Forms the central pyramid, adding crisp texture and fresh bulk to the plate.
- French salad dressing
- Adds moisture and tangy, seasoned flavor that coats the leeks and lettuce.
- Hard boiled egg
- Adds rich, soft texture and mild savory flavor as a garnish.
The step that matters
Blanch and boil the leeks in salted water until done, then drain and press dry.. Leeks must be cooked until tender but not mushy; pressing them dry removes excess water so the dressing clings instead of diluting.
