This comforting soup tastes so rich and creamy, yet there's not a drop of dairy in it! Garlic and abundant herbs and spices create bold flavor, while veggies and corn add heartiness and nutrition. Takes a little chopping preparation, but so worth it!
Soften the cashews: Either place in a small bowl and cover with cold water to cover, then let soak for at least an hour, the longer the better. Or, for a quicker method, pop the bowl of cashews and water in the microwave for a minute on high to boil, then let sit for about a half hour.
Heat the olive oil in a large soup pot over med-high heat. Add the onion and carrots, stirring, for about 2-3 minutes. Add the garlic and potatoes, cook for about 5 minutes, then add the veggie stock, soy sauce and all herbs and spices. Bring to a low boil, reduce heat to med-low and simmer for about 15-20 minutes until the carrots and potatoes are tender.
Transfer about 4 cups of the chowder mixture to a blender in batches. Drain the soaked cashews and add them to the blender. Make sure your blender has a way for steam to escape (remove center knob on lid) and place a paper towel over the opening to catch splash-ups. Blend first on low for about 15 seconds then increase speed to high and blend until smooth and creamy, for about a minute.
Return the pureed mixture to the remaining chowder in the soup pot, add in the corn and cook over medium heat for another couple minutes. Taste and add more salt and pepper if needed.
Garnish bowls of soup with the sliced scallions. Enjoy!
