This potato leek soup may look familiar, but I've refined my technique to ensure an even creamier, more luxurious result. In the past, I puréed the entire soup, but after elevating my cooking methods, I now mash the potatoes separately using a ricer, avoiding the dreaded gluey texture. The remaining ingredients are puréed for a smooth base, while the riced potatoes add the perfect velvety texture. The result is a comforting, flavorful bowl of soup with the perfect balance of texture and flavour—never gummy, always silky. This approach allows for an elevated yet comforting version of a classic.

Ingredients

Servings:

2 tbsp unsalted butter
1 tbsp oil
3–4 large leeks, white and light green parts only, roughly chopped (about 5 cups)
3 cloves garlic, peeled and smashed
2 lbs Yukon Gold potatoes, peeled and cut into 1/2-inch pieces
5 cups chicken or vegetable broth
2 bay leaves
3 sprigs fresh thyme, or 1 tsp dried thyme
1 tsp kosher salt
1/4 tsp ground black pepper
1/4 cup coffee cream (10% cream)
Chives or other fresh herbs, finely chopped, for garnish
1 tbsp lemon juice, totally optional

Instructions

1
Melt the butter in a large pot over medium heat. Add the leeks, cooking until soft, about 10 minutes, ensuring they don't brown. Add the garlic and cook for about 30 seconds.
2
Add the potatoes, broth, bay leaves, thyme, salt, and pepper. Bring to a boil, cover, then simmer for about 15–20 minutes until the potatoes are soft.
3
Remove the thyme and bay leaves. Pass the potatoes through a ricer, and purée the rest of the soup using an immersion blender or standard blender. If you don't have a ricer, just mash them with a potato masher. Also, consider leaving some potatoes chunky and only mashing half of the potatoes for more texture.
4
Return the riced potatoes to the pot, stir in the coffee cream, and simmer gently.
5
Adjust the consistency, if necessary, with more broth. Adjust the seasoning if necessary and garnish with chopped chives. Sometimes I like to add some lemon juice for extra brightness (but not always!).

FAQ

Can I make potato leek soup ahead of time?+

Yes, this soup keeps well for up to 4 days in the refrigerator or can be frozen for up to 3 months—just add the cream when you reheat it to maintain the best texture and flavor.

What can I use instead of coffee cream?+

You can swap in heavy cream, half-and-half, whole milk, or even Greek yogurt for a tangier version; just stir in your substitute at the end to avoid curdling.

Why is my potato leek soup watery or too thin?+

This usually happens when you blend it too much or use starchy potatoes instead of Yukon Golds—blend just until creamy rather than completely smooth, and stick with waxy potatoes that hold their shape better.

How do I make sure my leeks are clean before cooking?+

Since leeks trap dirt between layers, slice them lengthwise, fan out the layers, and rinse thoroughly under running water before chopping to remove any grit.
