To a large pot over medium heat, add the vegetable oil. Once hot add the onion and celery. Sauté for 5 minutes, stirring occasionally.
Add the corn to the pot and cook for another 5 minutes.
Add the garlic paste and cook for 30 seconds, stirring constantly so it doesn’t burn.
Add the butter and flour and stir to form a roux. Cook for 10 more minutes.
While stirring, pour the chicken broth, heavy cream, seasonings, and shredded chicken into the pot. Cook for an additional 8-10 minutes until thickened.
Ladle the soup into bowls and sprinkle chopped parsley on top if desired. Serve warm.
Notes
For the chicken, you can boil or bake the breasts ahead of time, or buy a rotisserie chicken at the store and shred the whole thing (discarding the skin).
This chowder is not spicy, but you could increase the cayenne or chili powder to increase the heat. The current measurements mostly add warmth and flavor to the chowder.
The amount of onion used can be reduced if you’re not a huge onion fan.
You can add 1 cup of diced carrots this recipe when the onions and celery go in the pot if desired.
