Easy Slow Cooker Vegan Leek and Potato Soup
A hearty soup without animal products but still full of rich flavor. Sauteing before slow cooking brings out the flavor of seemingly simple ingredients.
Ingredients
- ¼ cup vegan butter /
- 3 tablespoons olive oil /
- 2 large leeks, diced /
- 1 yellow onion, minced /
- 1 large carrot, diced /
- 1 cup minced Pleurotus mushrooms (oyster mushrooms) /
- 2 pounds potatoes, peeled and diced /
- 4 cups low-sodium vegetable broth /
- 1 cup unsweetened oat milk, divided /
- 1 tablespoon potato starch /
- salt and ground black pepper to taste
Instructions
Step 1
Turn on the Saute function on your slow cooker. Heat vegan butter and olive oil. Add leeks, onion, carrot, and mushrooms. Cook and stir until leeks and onions are translucent and softened, carrots have softened, and minced mushrooms have liquefied, about 7 minutes. Add potatoes and vegetable broth; mix well. Mix 1 tablespoon of the oat milk with potato starch to create a slurry and stir it into the soup.
Step 2
Heat remaining oat milk in a microwave-safe bowl in the microwave until hot, about 30 seconds. Pour it into the soup and season with salt and pepper. Turn off Saute function.
Step 3
Cook in the slow cooker on Low for 6 hours or on High for 3 1/2 hours. Stir soup before serving.
