This easy Potato Leek Soup recipe is a creamy, comforting French classic that's simple to make on the stovetop, in the Instant Pot, or slow cooker.
Unassuming Potato Leek Soup
It's like a reliable friend who isn't flashy, and is always there to comfort you, you know? I always make Potato Leek Soup in the cooler months and pair it with crusty Artisan No Knead Bread, soft Homemade Rolls, or ladled into a Homemade Bread Bowl. My kids absolutely love it too and it makes great leftovers. Plus, it's super versatile! Whether you need to make it dairy-free, vegetarian, or want to use your Instant Pot or slow cooker, this recipe adapts beautifully to fit your needs.

How to make Potato Leek Soup:
How to Chop Leeks: Chop off the small root end and the leaves. Rinse the remaining white and light green leek with water, checking for any dirt in the cracks. Chop the leeks thin, like you would celery.
Cook Bacon and Combine: Melt butter then add bacon, cooking until crisp. Add leeks and potatoes and cook until leeks are soft. Add white wine, stock, bay leaves, and thyme. Simmer until potatoes are very soft.
Blend and Add Cream: Blend soup with an immersion blender until it's creamy with just a few chunks. Remove from heat and cool slightly before adding the cream (we don't want it to curdle), or you can slowly temper the cream before adding it to the hot soup. Taste this easy potato and leek soup then season with salt, pepper, and a sprinkle of crushed red pepper or hot sauce, if desired. Let it cool slightly before serving (it will thicken slightly as it cools).
