This hearty fish chowder soup delivers a big bowl of comfort but not too heavy. The broth is so creamy, silky, and rich in flavors. It has a perfect consistency, not too thick and not too thin, very similar to New England chowder.
Render Bacon Fat: In a heavy-bottom pot or Dutch oven over medium heat, cook bacon for 5 minutes or until crispy and golden brown. Transfer the bacon to a plate and set aside. Keep about 2 tablespoons of bacon grease in the pot.
Add butter, onion, and celery. Cook and stirring occasionally over medium heat for about 5 minutes or until softened but not browned.
Deglaze the pan: Add white wine, cook at medium-high heat, stirring to scrape the brown bits from the bottom of the pan, until it has evaporated and reduced in half.
Add bay leaf, thyme, clam juice, broth, old bay seasoning, and potatoes. Bring to a boil then lower the heat. Cover the pot and cook until potatoes are almost done (firm on the outside but soft on the inside) for about 10 minutes or longer.
Add the fish fillets and preheated heavy cream into the pot. Cook, uncovered, on low heat for about 8-10 minutes. Adjust seasoning with salt/black pepper if needed.
Serve and enjoy with crispy bacon bits or allow the soup to chill at room temperature for up to an hour to enhance flavors. The broth will get thickened as it sits. Reheat at low heat just before serving. Do not let it boils.
