Drain juice from clams into a 6-quart saucepan or stockpot over medium heat. Add the onions, celery, potatoes and carrots. If needed, add water to cover the vegetables, and simmer over medium heat until tender.
Meanwhile, in a 2-quart saucepan, melt the butter over medium heat. Whisk in flour until smooth. Cook for 1-2 minutes, until bubbly. Gradually whisk in half-and-half, 1 cup at a time, and keep whisking until soup is thick and smooth.
Add half-and-half mixture to pot with vegetables. Stir in clams just before serving. When clams are heated through, stir in seasoning, then salt and pepper, to taste.Serve warm in sourdough bread bowls.

Notes
Giving the bowl a quick run in the oven under your oven's broiler can keep the bread bowl from getting soggy. But if you’d prefer to maintain that fluffy texture, use clean hands to press down on the soft center, sort of smushing the bread against the crusty sides so that the soup doesn’t penetrate as much.
We recommend checking big retailers like Costco, Sam's Club, BJs, Smart & Final, Amazon, or Walmart online for large cans of minced clams to make this soup more budget-friendly.
Recipe Variations:
Bacon and garlic clam chowder: Add a savory depth by sautéing minced garlic and chopped bacon before cooking the vegetables. Use a bit of the bacon grease to flavor the soup base, then garnish with crispy bacon bits for a smoky finish.
Herbed chowder with leeks and thyme: Swap out onions for thinly sliced leek and add a bay leaf and sprig of fresh thyme while simmering the vegetables. This simple herb combo gives the chowder an aromatic boost that pairs beautifully with the clams.
Rustic pork and clam chowder: Inspired by old-school coastal recipes, stir in a spoonful of pork fat or bacon drippings to start your roux. Use hearty clam meat and finish with a sprinkle of chopped parsley for a warm and rustic version of this classic.
