Melt the butter in a large pot over medium heat.
2 tablespoons butter
Add the onion, garlic, celery, and carrot. Stir frequently and cook for 4-5 minutes, until the onions look translucent (slightly see-through) and the carrots start to soften.
1 small onion, 2 cloves garlic, 2 celery stalks, 1 large carrot
Stir in the diced potatoes and pour in the chicken broth.
2 medium gold potatoes, 3 cups chicken broth
Bring the mixture to a boil, then reduce the heat to low. Cover the pot with a lid and let it simmer for 10-12 minutes. The potatoes are ready when you can easily pierce them with a fork.
Stir in the heavy cream.
2 cups heavy cream
In a small bowl or liquid measuring cup, ladle out 1 cup of hot broth from the pot. (Note 2)
Add the flour, one tablespoon at a time, whisking constantly to create a smooth, lump-free mixture.
¼ cup flour
Slowly pour the slurry back into the pot while stirring to thicken the chowder.
Add the shrimp, scallops, and white fish.
½ pound medium shrimp, 3-4 large scallops, ½ pound white fish
Reduce the heat to low and simmer gently for 5-7 minutes. Avoid boiling to prevent the cream from curdling (See Note 3).
Stir in the smoked paprika, thyme, and a pinch of salt and pepper.
½ teaspoon smoked paprika, ¼ teaspoon dried thyme, Salt and pepper
Taste the chowder and adjust the seasoning if needed. Let it sit on low heat for 2-3 minutes to allow the flavors to meld.
Ladle the chowder into bowls and garnish with fresh parsley or chives.
