For an even richer flavor, consider adding a splash of dry white wine during the sautéing process. A pinch of nutmeg stirred in before serving can also add a delightful warmth. Feel free to experiment with different types of potatoes. Yukon Golds will lend a creamy texture, while Russets will result in a slightly thicker soup. If you prefer a completely smooth soup, use an immersion blender to purée it before serving. Be cautious when blending hot liquids.

Follow The Directions
01
StepEngage the Sauté function on your slow cooker. Melt vegan butter and olive oil in the pot. Introduce the leeks, onion, carrot, and mushrooms. Sauté until the leeks and onions become translucent, the carrots soften, and the mushrooms release their moisture, approximately 7 minutes.
02
StepIncorporate the diced potatoes and vegetable broth; ensure a thorough mix. In a separate small bowl, whisk together 1 tablespoon of oat milk with the potato starch to form a smooth slurry. Gently stir this slurry into the simmering soup.
03
StepWarm the remaining oat milk in a microwave-safe bowl until heated through, about 30 seconds. Introduce the warmed milk into the soup and season generously with salt and pepper. Deactivate the Sauté function.
04
StepSet the slow cooker to Low for 6 hours or High for 3 1/2 hours. Stir well before serving to ensure a harmonious blend of flavors and textures.

May 24, 2025My leeks were a bit sandy, so I made sure to wash them really well before dicing. The soup turned out perfectly!
