Step-by-Step Instructions
Step 1: Prepare the Leeks
Clean your leeks meticulously by slicing them in half lengthwise and rinsing between the layers under cold water. Leeks are notorious for harboring grit, and this thorough cleaning ensures a silky soup without unwanted texture. After cleaning, slice them into thin half-moons. TIP: Place sliced leeks in a bowl of cold water and swish them around—any remaining dirt will sink to the bottom.
Step 2: Sauté the Aromatics
In a large Dutch oven or heavy-bottomed pot, melt butter over medium heat. Add leeks and garlic, seasoning with a pinch of salt to help them release moisture. Sauté for 5-7 minutes until soft and translucent but not browned. This slow cooking develops sweet, mellow flavors that form the foundation of your lemony leek and potato soup.
Step 3: Add Potatoes and Broth
Add cubed potatoes to the pot, stirring to coat with the buttery leek mixture. Pour in the vegetable broth, ensuring potatoes are fully submerged. Bring to a gentle boil, then reduce heat and simmer for 15-20 minutes until potatoes are fork-tender. TIP: Cut potatoes into uniform sizes (approximately 1-inch cubes) for even cooking.
Step 4: Blend to Perfect Consistency
For the creamiest texture, use an immersion blender to purée the soup directly in the pot until smooth. If using a standard blender, work in batches and remember to vent the lid to prevent pressure buildup. For a rustic version, blend only three-quarters of the soup, leaving some potato chunks for textural interest.
Step 5: Finish with Lemon and Cream
Return the blended soup to low heat. Stir in milk or cream, then add lemon zest and juice. Add fresh thyme leaves and season with salt, pepper, and optional nutmeg to taste. Heat gently without boiling (to prevent curdling) for 3-5 minutes. Serve immediately, garnished with fresh chives and an extra lemon wedge.

FAQs
Can I make this soup vegan?
Absolutely! Simply substitute the butter with olive oil and use coconut milk or cashew cream instead of dairy. These plant-based alternatives maintain the creamy texture while adding subtle complementary flavors.
How can I tell when leeks are fresh at the store?
Look for leeks with firm white bases and crisp, dark green tops. Avoid those with yellowing or wilted leaves. The freshest leeks will have a mild onion scent rather than a strong odor.
Can I prepare components of this soup in advance?
Yes! Clean and slice leeks up to 2 days ahead, storing them in a sealed container in the refrigerator. You can also pre-cook the soup base through the blending stage, then add the cream and lemon just before serving.
Why does my soup sometimes curdle when I add lemon?
Curdling occurs when acidic ingredients like lemon are added to hot dairy. Prevent this by tempering your cream (warming it slightly before adding), ensuring your soup isn’t boiling, and adding lemon gradually while stirring continuously.
Is lemony leek and potato soup freezer-friendly?
Yes, but freeze it before adding cream. When reheating, thaw completely and add fresh cream and a squeeze of lemon to revive the bright flavors that may have diminished during freezing.
