01 - Melt butter in a large pot over medium heat. Add onion, celery, and carrot. Sauté until softened, about 5 minutes.
02 - Stir in garlic and cook for 1 minute until fragrant.
03 - Add diced potatoes, corn, salt, pepper, paprika, thyme, and bay leaf. Stir to combine thoroughly.
04 - Pour in vegetable broth. Bring to a boil, then reduce heat and simmer for 15–20 minutes until potatoes are tender.
05 - Remove and discard the bay leaf from the pot.
06 - Using an immersion blender, blend a portion of the chowder directly in the pot for a creamier texture, leaving some chunks for body. Alternatively, transfer 2 cups of chowder to a blender, purée, and return to the pot.
07 - Stir in milk and heavy cream. Simmer gently for 5 minutes to heat through without boiling.
08 - Taste and adjust seasoning as needed. Ladle into bowls and garnish with chives, parsley, or bacon if desired.
