Red Curry-Lime Sweet Potato Soup

Yes, this warm, cozy fall recipe is a great way to use up some of your Thanksgiving leftovers, but why wait around until after T-Day hoping you just might have enough leftover mashed sweet potatoes on hand? Go ahead and bake a few now before making this luscious, velvety soup. Then when you’ve got about a half hour, you can whip it together and have it ready to eat in no time.

I think using a homemade chicken broth instead of water adds additional depth of flavor, but if you’re sticking to vegetarian, a veggie broth or water will do just fine. You can also substitute cilantro in place of basil as a garnish if that’s what you prefer.

Want a heartier meal? Grilled Swiss cheese sandwiches make great companions. We made ours from Ezekiel 100% sprouted whole grain bread slices (no flour, no gluten). My go-to for an added flavor punch is a schmear of Dijon mustard. Additionally, although I didn’t have any at the time, a few slices of tomato in that sandwich would take it over the top.

Next time you’re serving sweet potatoes for dinner, cook up a few extra and put them aside, and you’ll be ahead of the game in making this soup again—because, yes, you’ll want to.
