Use brown lentils if you want to use another type of lentils. If you add green lentils or black lentils, keep in mind they may need an additional 10-20 minutes.

Replace the shallots with yellow onion if needed, but add a pinch of sugar to mimic the sweetness.
How to serve this vegan red lentil soup and sweet potato soup recipe
What’s the best way to serve my vegan red lentil soup with sweet potatoes?
Try serving it with a delicious vegan sandwich or my quick and easy summer salad recipe. You can also serve it with toasted garlic bread, sweet cornbread, or even roasted vegetables! If you want a little coolness, add a dollop of vegan sour cream on top for added coolness.
For a creamy soup without chunks, use an immersion blender (stick blender) until smooth. I recommend setting aside some broth before blending so you can control the texture.
Is vegan red lentil soup with sweet potatoes good for leftovers?
Yes, it is! This soup will last in your refrigerator for up to 4 days and requires no meal prep. Like many great soups, this recipe keeps building more and more flavor the longer you have it.
To reheat your soup with the same original texture, add vegetable broth or water to thin it out. It’ll come right back to life after 10-15 minutes of simmering over medium low heat.
Can vegan red lentil soup with sweet potatoes be frozen?
You totally can! This vegan red lentil soup recipe with sweet potatoes will hold up in the freezer for about 2 months, making it perfect for future cravings. I recommend making a larger batch and saving the soup in either freezer-safe bags or BPA-free plastic soup containers.
When you’re ready to reheat, start by thawing your soup in warm water (while still in the bag or container). When it starts to loosen up, transfer the contents into a medium pot on the stove. You can also let the soup come to room temperature on the counter and then reheat. Simple as that!
