Prepare the Croutons: Preheat oven to 375°F (190°C). In a bowl, toss bread cubes with olive oil, salt, and pepper. Spread on a baking sheet and bake for 10-12 minutes or until golden and crisp. Set aside.
2 cups day-old bread cubes, 1 tbsp olive oil, Salt and pepper
Sauté Aromatics: In a large pot, melt butter over medium heat. Add onion, celery, and garlic. Sauté until onions are translucent, about 5 minutes.
1 medium onion, 2 celery stalks, 2 garlic cloves, 2 tbsp butter
Add Potatoes and Broth: Stir in diced potatoes. Pour in the broth and bring to a gentle simmer. Cook for 10-12 minutes, until potatoes are fork-tender.
2 medium potatoes, 2 cups seafood broth
Open the Clams: Rinse the clams thoroughly. Add them to the pot, cover, and cook until the shells open, about 5-7 minutes. Discard any that remain closed.
2 lbs Pacific White Shell Clams
Thicken (Optional): If you prefer a thicker chowder, whisk the optional flour into the milk before adding. This helps prevent lumps.
1 tbsp all-purpose flour
Add Dairy: Pour in heavy cream and milk. Stir gently, and season with salt and pepper to taste. Simmer for 5 minutes more. Avoid boiling to prevent curdling.
1 cup heavy cream, 1 cup milk, Salt and pepper
Serve and Top with Croutons: Ladle the chowder into bowls. Sprinkle with homemade croutons just before serving for a delightful crunch.
