The perfect bowl of clam chowder on a cool evening is just about the best, and making it yourself is definitely the best. This is a great recipe - easy, quick, and everything good chowder should be.
Heat the butter in a large pot over medium-high heat. Add carrots, onions, and celery and garlic, onion powder, bay leaves, and thyme. Stir and saute until softened. Sprinkle flour over the mix and stir for 1 minute to cook the flour.
Add the stock, heavy cream, clam juice (set clams aside), bay leaves, thyme, and potatoes. Stir and bring to a simmer. Reduce the heat to medium-low and cook 20 minutes, stirring often, until the potatoes are nice and tender. Remove thyme sprigs and bay leaves.
Add clams, salt, and pepper. Cook until clams are just firm, another 2-5 minutes.
Stir and serve hot and fresh with oyster crackers, of course!
