Begin by gathering all your ingredients. If you're using frozen corn, make sure it's thawed before you start cooking. Chop the potatoes and carrots into bite-sized pieces, and finely mince the garlic cloves.
Set your Instant Pot to saute mode. Once it is hot, add a dash of olive oil and sauté the garlic until it becomes fragrant.
1 tablespoon olive oil, 4 garlic cloves
Add chopped onions and saute until they turn translucent. Then, add carrots and corn to the pot.
2 carrots, 1 onion, 4 cup corn kernels
Add chopped potatoes, bay leaf, nutritional yeast, cashews, and spices, and mix well.
3 potatoes, ½ teaspoon cayenne pepper, ½ teaspoon black pepper powder, 1 teaspoon Italian seasoning, ¼ teaspoon turmeric powder, ¾ cup cashews, ¼ cup nutritional yeast, 1 bay leaf, salt to taste
Add the vegetable broth to the pot, making sure all the ingredients are covered. Close the lid of your Instant Pot and set it to manual high pressure for 8 minutes.
4 ¾ cup vegetable broth
Once the timer expires, use the natural release option for 10 minutes before using the quick release option to release the remaining pressure.
Open the lid and give your corn chowder a good stir. If you prefer a creamier consistency, you can use an immersion blender or a high-speed blender to blend some of the soup. (I blended all the soup). While blending take out the bay leaf.
Transfer the soup to a large pot and serve hot with your choice of toppings, such as red pepper flakes, green onions, chopped tortillas, roasted corn, or fresh herbs.
