This creamy, butter-based Clam Chowder is thick, hearty, and perfect for fish fry season. Made without bacon, it’s rich and satisfying with just a hint of clam flavor.
In a Dutch oven over medium heat, melt butter. Add onion and celery and cook until softened, about 5 minutes.
Stir in garlic, thyme, and bay leaf until fragrant, about 30 seconds. Sprinkle in flour and cook, stirring constantly, until pale golden and nutty but not browned, about 2 to 3 minutes.
Gradually whisk in milk until smooth. Stir in clam juice and the liquid from the canned clams. Add potatoes.
Bring to a boil, reduce heat, and simmer uncovered, stirring occasionally, until potatoes are tender and soup is thickened, about 15 to 20 minutes.
Stir in half-and-half and return to a gentle simmer. Add chopped clams and cook just until heated through, 1 to 2 minutes. Do not boil.
Remove bay leaf and season to taste with salt and pepper (I like 1 teaspoon salt and 1/2 teaspoon pepper). Serve with oyster crackers.
