Have you ever made Lettuce Soup? Lettuce is a much-overlooked ingredient. As well as serving as a salad, you can braise it and serve as a vegetable, and you can make a delicious soup.

Reduce, Recycle, Reuse Lettuce
Soup is also a brilliant way to use lettuces from the garden or allotment that have bolted and are past their best.
Even better you can use that forgotten lettuce at the bottom of the fridge, you know, the one that is slightly limp, maybe a little brown around the edges. Not a wet and slimy lettuce, I’m afraid that one goes in the compost heap.
Growing Lettuce
Lettuce has to be one of the easiest crops to grow. Salad Bowl lettuce is the easiest and you can pick as much as you need and then come back for more.
Other lettuces are no more difficult, you simply plant the seeds and keep them watered and they will grow. You do need to watch out for slugs and other predators but some of your seeds will germinate and survive.
Lettuce grows well in containers too, so if you don’t have a patch of ground you can still grow lettuce. Pay attention to the watering as this is even more crucial when a plant is in a container.

How to Grow Salad Bowl Lettuce is a step by step guide to show you how easy it is to grow salad leaves so you can enjoy fresh salad all summer long.
Can I freeze lettuce soup?
Yes, let the soup cool, then put in a freezer-proof container and freeze for up to 3 months. To use the soup either thaw overnight in the fridge or, heat gently in a saucepan from frozen, stirring frequently. You can also thaw on the defrost setting of the microwave.
Can I serve lettuce soup cold?
Lettuce soup is very good served either warm or cold. If serving cold, then make sure it is really well chilled. It would be perfect served in shot glasses as part of a buffet or afternoon tea.
What other vegetables can I add to Lettuce Soup?
Traditionally Lettuce Soup is made only with lettuce and onions or leeks, but you can add many other vegetables to your lettuce soup.
As long as there is more lettuce than other ingredients, then you won’t lose the delicacy of flavour.
Here are a few ideas:
- I always add a few carrots, as they provide a little sweetness.
- Chard leaves
- Spinach leaves and stems
- Pak (Bok) Choi
- Celery
- Peas
Lettuce Soup is really quick and easy to make, so next time you are about to throw out lettuce, remember you can make Lettuce Soup!

More Spring and Summer Soup Recipes from Farmersgirl Kitchen
Carrot and Tomato Soup is one of my favourite soups, it’s rich and creamy, full of flavour, really easy to make and very economical. You can use up all the dodgy carrots at the bottom of your fridge drawer, add a couple of cans of tomatoes, an onion, some stock, and a little milk, and you will have enough soup for 8 people.
Scottish Summer Vegetable Soup is perfect for those cooler days of summer when you crave a little comfort food. It’s the summer equivalent of my Scotch Broth recipe but this time packed full of summer vegetables and herbs.
Wild Garlic, Ham and Pea Chowder is a chunky soup using potatoes, peas, ham, and wild garlic leaves. The soup has a mild garlic flavour and is creamy and totally delicious.

I’ve never actually tried lettuce soup before, but I am forever finding half-eaten, browned lettuces in the salad drawer so I should probably give it a try!

This recipe is definitely for you Hannah! You can add lettuce to any soup you are going to blend.
Helen @ family-friends-food.com says
