Step‑by‑Step Instructions for Instant Pot Potato Leek Soup

Step 1: Prepare the Leeks
Begin by thoroughly cleaning the leeks, making sure to remove any grit hidden between the layers. Slice the cleaned leeks into thin rounds, aiming for uniformity to ensure even cooking. Set aside the prepared leeks as we get ready to sauté and build the flavors for your Instant Pot Potato Leek Soup.

Step 2: Sauté the Aromatics
Use the “Sauté” function on your Instant Pot and melt a generous pat of butter. Once melted, add the sliced leeks, diced celery, and minced garlic. Sauté the mixture for about 5-7 minutes, stirring often, until the leeks become soft and translucent, filling your kitchen with a fragrant aroma that signals deliciousness ahead.

Step 3: Add the Potatoes and Broth
Next, incorporate the chopped russet potatoes into the pot, stirring to combine them with the sautéed leeks and garlic. Pour in your vegetable broth, ensuring the potatoes are fully submerged. Add fresh thyme and a bay leaf to infuse the soup with herby goodness, making sure everything is well mixed before we move to the cooking phase.

Step 4: Cook Under Pressure
Secure the Instant Pot lid, ensuring the vent is in the sealing position. Select the “Manual” or “Pressure Cook” option and set the timer for 10 minutes on high pressure. As the pot comes to pressure, excitement builds; this step allows the flavors to blend beautifully while cooking the potatoes until tender and ready for blending.

Step 5: Release the Pressure and Blend
Once the cooking time is complete, carefully perform a quick release of the pressure by flipping the valve. Once it’s safe, remove the lid and use an immersion blender to purée the soup until it reaches a silky-smooth consistency. If you don’t have an immersion blender, you can transfer the mixture in batches to a countertop blender—just be cautious with the hot liquid.

Step 6: Stir in the Cream
After blending the soup, return to the pot if needed, and stir in the heavy cream until fully integrated. This addition is what gives your Instant Pot Potato Leek Soup its creamy texture and richness. If the soup seems too thick for your liking, feel free to add more broth until you achieve your desired consistency, then heat through for a couple of minutes.

Step 7: Taste and Adjust Seasoning
Finally, taste the soup and adjust the seasoning as needed. This is your chance to elevate the flavor profile—add salt and pepper according to your preference. Once satisfied with the taste, ladle the warm soup into bowls, and consider garnishing with a drizzle of cream or fresh herbs for a pop of color before serving alongside your crispy crostini.
