Step 1: Prepare the Base : In a large pot or Dutch oven, melt the butter over medium heat. Add bacon and cook until crisp. Remove and set aside (leave about 1 tablespoon of fat in the pot). Add the onion, celery, and carrot. Sauté until softened and translucent (about 5 minutes). Stir in garlic and cook for another 30 seconds, until fragrant.
Step 2: Add the Potatoes and Corn : Add diced potatoes and corn to the pot. Stir to coat with the buttery mixture.
Step 3: Build the Broth : Sprinkle in the flour and stir well to form a light roux (this helps thicken the chowder). Slowly pour in the seafood stock, whisking constantly to avoid lumps. Add Old Bay, smoked paprika, salt, and pepper. Simmer for about 15 minutes, until the potatoes are tender.
Step 4: Add Milk, Cream, and Crab : Reduce heat to low. Stir in milk and cream. Add the crab meat gently, ensuring not to break it up too much. Simmer for another 5–7 minutes, allowing flavors to meld. Adjust seasoning with salt, pepper, and a squeeze of lemon juice.
Step 5: Finish and Serve : Stir in fresh parsley and return the cooked bacon to the pot. Ladle into bowls, garnish with parsley, chives, or a dash of paprika.
