01 - Melt butter in a large pot or Dutch oven over medium heat. Add diced onion, celery, and carrots. Sauté for 5 minutes until vegetables are softened and fragrant.
02 - Stir in minced garlic and cook for 1 minute until fragrant, being careful not to burn it.
03 - Add diced potatoes, corn kernels, thyme leaves, smoked paprika, salt, and black pepper. Stir thoroughly to distribute seasonings evenly.
04 - Pour in vegetable broth and bring mixture to a gentle boil. Reduce heat to low and simmer for 15 minutes, or until potatoes are fork-tender.
05 - Using an immersion blender, blend approximately one-third of the soup directly in the pot to create a velvety base while maintaining chunky vegetable pieces. Alternatively, transfer a portion to a countertop blender and return to pot.
06 - Stir in whole milk and heavy cream. Simmer gently for 5 additional minutes to heat through and flavors meld. Do not allow soup to reach a rolling boil.
07 - Taste chowder and adjust seasoning with additional salt or pepper if needed. Serve hot in bowls, garnished with chopped fresh chives, parsley, or crumbled bacon if desired.
