Like pumpkin soup? Like sweet potato soup? Then why not combine the two with this super simple soy-free vegan pumpkin and sweet potato soup recipe? Pumpkin and sweet potatoes are simmered on the stovetop with white wine and fresh thyme in this simple yet delicious and nourishing recipe. As veggies that are in season typically at the same time, the flavors from pumpkin and sweet potatoes naturally complement each other. Smaller pumpkins work really well here; you'll often see them at farmers markets or grocery stores labeled as pie pumpkins or sugar pumpkins. The ones buy for carving are a bit flavorless in comparison and often simply called field pumpkins in comparisonsave those for roasting the seeds and using the seeds in other ways. However, if you don't have a pumpkin, you can always substitute butternut squash instead, which is an equally good winter squash option. This pumpkin and sweet potato soup is the perfect fall or autumn soup recipe for your vegetarian or vegan meal. You can serve it as is with a green salad for a light lunch or dinner.
