Roasted Sweet Potato Soup with Coconut Corn

Sweet potato soup is one of those recipes that just feels right in the cooler months.

Roasting the sweet potatoes gives the soup a deeper flavor you don’t get from just boiling. It caramelizes the natural sugars and adds a nice texture.

This soup is cozy, filling, and surprisingly bright thanks to a splash of lime juice and a hit of soy sauce.

It’s vegetarian, easy to make, and perfect when you need something warm but not heavy.

You might not think soy sauce belongs in a chowder, but it’s a little trick that makes a big difference.

Ingredients

For roasting the sweet potatoes:

2 large sweet potatoes, peeled and cubed
1 tablespoon olive oil for roasting
½ teaspoon smoked paprika
¼ teaspoon cayenne (optional, if you like a hint of spice)
Salt and pepper to taste

For the chowder:

1 tablespoon butter or olive oil
1 medium onion, diced
3 garlic cloves, minced
1 red bell pepper, diced
1 cup corn kernels (fresh or frozen)
1 teaspoon thyme
1 teaspoon smoked paprika
1 can (14 oz) coconut milk
2 cups vegetable broth
1 tablespoon soy sauce (the secret umami hit)
1 tablespoon lime juice
Salt and pepper to taste

Optional toppings:
Chili crisp
Green onions
Fresh cilantro
Lime zest
Toasted pumpkin seeds
