Weight Watchers Recipe of the Day: Sweet Potato Tomato Soup
This simple sweet potato tomato soup (for the stovetop or slow cooker) is a light, healthy and delicious way to use up any leftover Thanksgiving sweet potatoes taking up space in your fridge. It’s just the thing to get you back on track after a day or two of heavy eating.

I hope you had a wonderful Thanksgiving! We spent the day here at home, in the company of family and friends. What could be better?
Taking time Tuesday night to get several side dishes done ahead made for what felt like an easy, effortless, yet delicious dinner. Having my mother and sister bring several dishes also helped a lot.
Mom brought her spectacular mashed potatoes, along with shrimp cocktail (she insisted) and a beautiful relish tray. My sister brought yummy breads (rolls, cranberry walnut, and pumpkin) and desserts (pumpkin pie and a variety of little tasty tarts from a wonderful bakery/cafe in Tucson called, Beyond Bread.)
Did we have way more food than we needed? Absolutely. It’s a long-standing family tradition!
The good news is that I can take the whole rest of the weekend off from major cooking, depending instead on the creative use of leftovers. We also intend to share some of our bounty with a few friends who adore Thanksgiving food.
What to do with your leftover sweet potatoes?

How about soup? I first made this soup when I had several leftover baked sweet potatoes I needed to use up. We thought it was delicious!

Sweet Potato Tomato Soup Recipe
Ingredients
- 1 teaspoon olive oil
- 1 medium onion, chopped
- 5 cups vegetable broth (affiliate link)
- 3 cups leftover cooked sweet potatoes
- 2 cups canned tomatoes with their juice
- 3/4 cup orange juice
- Salt and pepper to taste
- Additional water to achieve desired consistency
Instructions
- In a large saucepan set over medium heat, cook the onion in the oil, until it begins to soften and become translucent.
- Add the broth, sweet potatoes and tomatoes and bring to a boil, reduce heat and simmer, stirring occasionally, for 15 to 20 minutes. (Slow Cooker Directions: Alternatively toss the onions, broth, sweet potatoes and tomatoes into the slow cooker. Cover and cook on LOW until the vegetables are tender, 6 to 8 hours.)
- Remove from the heat and allow to cool slightly. Then puree in a blender (affiliate link) or food processor (affiliate link) until smooth. (This may require two batches.)
- Return the mixture to the saucepan or slow cooker. Stir in the orange juice and additional water, if the soup seems to thick. Season to taste with salt and pepper.
- Heat gently until hot.
- Serve immediately.
