Step-by-Step Instructions

Step 1: Prepare the Leeks

Leeks often trap dirt between their layers, so cleaning them properly is essential. Slice the leeks thinly, then place them in a bowl of cold water. Swirl them gently to loosen any sand or grit, then lift them out with your hands. Drain thoroughly before cooking.

Step 2: Sauté the Aromatics

In a large soup pot, melt the butter over medium heat. Add the sliced leeks and chopped onion. Cook slowly, stirring occasionally, until the leeks become soft and translucent. This step takes about 10 minutes. You want to sweat them gently without browning that’s how you build the delicate base flavor of creamy potato leek soup.

Step 3: Add Garlic and Potatoes

Step 4: Add Broth and Simmer

Pour in the vegetable broth or chicken stock. Increase the heat and bring to a gentle boil, then reduce to a simmer. Cook uncovered for 20 minutes or until the potatoes are completely tender. Stir occasionally to prevent sticking.

Step 5: Blend Until Smooth

Once the potatoes are soft, remove the pot from heat. Use an immersion blender directly in the pot to puree until creamy and smooth. If you’re using a countertop blender, let the soup cool slightly before blending in batches for safety.

Step 6: Add Cream and Season

Return the blended soup to the pot and stir in the cream (or your preferred dairy substitute). Reheat gently on low heat, and taste to adjust salt and pepper. The consistency should be rich and velvety, not too thick or watery.
