Ingredients
You only need a few simple ingredients to make this easy lettuce soup recipe!
- Romaine Lettuce - I find romaine (the kind you use for caesar salad) or other thick lettuce is best for this soup recipe. Since this isn't a blended soup, it holds up better after cooking.
- Peas - For extra veggies, add frozen peas, or even frozen chopped carrots or corn, or a mixture.
- Oil, onion and garlic - the flavor base for the soup recipe.
- Vegetable stock - you can even swap to Mushroom Stock or Vegan Chicken Broth.
- Seasonings - black pepper and lemon juice - these seasonings really lift the delicate flavor of the soup.
- Optional garnishes - Yogurt or sour cream (or vegan versions), chopped fresh mint leaves, lemon zest.

Prep the lettuce: Chop the romaine lettuce into chunks.
Make the flavor base of the soup: Heat the oil in a soup pot, then add the onion and cook until soft, stirring often, about 5 minutes. Stir in the garlic and cook for a further minute.
Add the rest: Add the stock, lettuce, and peas, bring to a boil then reduce the heat and simmer for 5 minutes.
Finish with seasonings: Stir in the lemon juice and pepper.
Get fancy with garnishes, if desired: Serve garnished with a little yogurt or sour cream and chopped fresh mint leaves.
Substitutions
- Lettuce - instead of Romaine lettuce, you can use iceberg or bagged lettuce leaves.
- Peas - feel free to swap the peas for other diced or small frozen vegetables. It's great with carrots, corn and green beans.
- Vegan - The soup itself is vegan, but to keep it vegan be sure to use dairy free yogurt or sour cream for the garnish.
Variations
- Add a pinch of chili pepper flakes while cooking to imbue heat into the soup.
- Try it topped with Air Fryer Croutons.
- Instead of yogurt topping, try it with Sriracha Aioli.
- Prefer smooth soups? Add your lettuce soup to a blender and puree it until smooth.
- Serve it topped with a little gruyere melted onto a slice of Garlic Bread.
Storage
Store: Store your lettuce soup in an airtight container in the fridge for up to 3 days. This soup is best served immediately.
Reheat: Add your soup to a pot and reheat gently on the stove, or add it to a microwavable dish and microwave for a few minutes until heated through, stirring halfway.
Freeze: This soup is not recommended for freezing.
Top tip
For best results, enjoy this soup immediately, so the texture of the lettuce stays slightly firm.
