01 - Melt butter in a large pot over medium heat. Add onion, celery, and carrot. Sauté for 5 minutes until softened.
02 - Stir in minced garlic and cook for 1 minute until fragrant.
03 - Sprinkle flour into the pot, stirring constantly for 1-2 minutes to form a smooth roux and cook out raw flour taste.
04 - Gradually whisk in vegetable broth until fully incorporated and smooth, ensuring no lumps remain.
05 - Add diced potatoes and bring mixture to a boil. Reduce heat, cover, and simmer for 12-15 minutes until potatoes are fork-tender.
06 - Stir in corn kernels, salt, black pepper, and smoked paprika. Simmer for an additional 8-10 minutes until corn is heated through.
07 - Reduce heat to low. Pour in milk and heavy cream, stirring gently to combine. Heat through thoroughly but avoid boiling to prevent curdling.
08 - Use an immersion blender to puree approximately one-third of the soup directly in the pot, creating a creamy base while preserving chunky texture.
09 - Taste the chowder and adjust salt and pepper as needed to achieve desired flavor balance.
10 - Ladle hot chowder into serving bowls and sprinkle generously with fresh parsley and chives.
