This creamy Thai-inspired soup is all about balance: When the contrasting flavors are in harmony, it is outrageously delicious. (It is also vegan if there’s no fish or shrimp in your curry paste.) Supermarket curry pastes are a great shortcut to flavor for weeknights, but salt and spice levels can vary greatly among brands. So taste at the end, and adjust: You may need to add curry paste, sugar or lime juice to your liking. Chile-lime flavored peanuts, available at some grocery stores, are particularly good for topping — snap them up if you happen to see them. Otherwise, roasted salted peanuts will work beautifully.
Recipe by Sarah DiGregorio for the New York Times
Serves 6
2 ½ lbs sweet potatoes, peeled and cut into 1- to 2-inch chunks
1 medium yellow or red onion, chopped
5 large garlic cloves
2 tbsp coconut oil, preferably unrefined virgin
2 tbsp packed light brown sugar
1 tsp turmeric
½ tsp kosher salt, plus more to taste
1 (4-oz) jar red curry paste (1/2 cup)
1 (13-oz) can full-fat coconut milk
1 cup smooth peanut butter
Juice of 1 lime, plus more to taste
5 oz/1 medium bunch baby kale or spinach, stemmed and chopped
Combine the sweet potatoes, onion, garlic, oil, sugar, turmeric and salt in a 5- to 8-qt slow cooker. Add more than half of the jar of curry paste (about 1/3 cup) and 1 cup of water or broth. Stir to combine all the ingredients and cook on low until the potatoes are quite tender, about 8 hours.
Add the coconut milk, peanut butter, remaining curry paste and 2 1/2 cups water to the slow cooker.
Using an immersion blender, purée the soup until it is uniformly creamy.
Add the lime juice and the kale, and stir to combine. Cook on low until the greens are wilted and tender, about 10 minutes. Stir in more warm water/broth if you would like a looser texture.
Taste and add more lime juice or salt if necessary.
Serve in bowls with peanuts on top.
