Step-by-Step Instructions for Making the Soup

Step 1: Prep the Vegetables
Wash the leeks thoroughly to remove any hidden grit. Slice them into thin rounds. Peel and dice the potatoes and finely chop the onion.
Step 2: Sauté the Aromatics
Melt the butter in a large pan over medium heat. Add the chopped onion and leeks, and cook gently for about 10 minutes until soft and fragrant.
Step 3: Add the Potatoes and Stock
Add the diced potatoes and pour in the vegetable stock. Bring the mixture to a gentle boil, then reduce the heat and let it simmer for 20–25 minutes until the potatoes are tender.
Step 4: Blend the Soup
Use a hand blender to purée the soup until smooth. You can leave a few chunky bits for added texture if desired.
Step 5: Finish with Cream
Stir in the double cream, if using, and season with salt, pepper, and thyme to taste. Heat for an additional 5 minutes and serve hot.

- Always clean the leeks thoroughly; they often trap dirt between layers.
- Use waxy potatoes like Yukon Gold for the best creamy texture.
- Add cream at the end to prevent curdling.
