Leeks
Leeks provide a mild onion flavor that becomes sweet after cooking. Wash thoroughly since dirt often hides between the layers.
Potatoes
Yukon Gold potatoes create the creamiest soup, while Russets also work well.
Cream
Heavy cream gives the soup a luxurious finish. Half-and-half can be substituted for a lighter version.
Cheese
Freshly grated cheese melts more evenly than pre-shredded varieties.

Step-by-Step Instructions
Step 1: Cook the Leeks
Melt butter with olive oil over medium heat. Add the sliced leeks and onions. Cook gently for about 8–10 minutes until soft and fragrant without browning.
Why it matters: Slow cooking develops the leeks’ natural sweetness.
Step 2: Add Garlic
Stir in the garlic and cook for one minute.
The garlic should become aromatic but never brown, which could make the soup bitter.
Step 3: Add Potatoes and Stock
Add the diced potatoes along with the stock. Bring everything to a gentle boil before reducing to a simmer.
Cook for about 20 minutes until the potatoes are fork tender.
Step 4: Blend Until Smooth
Use an immersion blender or countertop blender until silky smooth.
If you prefer texture, blend only part of the soup.
Step 5: Finish with Cream
Return the soup to low heat.
Stir in the cream and season generously with salt and black pepper.
Avoid boiling after adding the cream.
Step 6: Make the Cheesy Toast
Spread butter over the bread.
Sprinkle generously with shredded cheese and herbs.
Bake until the cheese bubbles and turns golden brown.
Step 7: Serve
Ladle the soup into warm bowls.
Top with freshly cracked black pepper and chopped herbs.
Serve immediately with crispy cheesy toast.
Expert Tips
- Clean leeks thoroughly before cooking.
