A rich, creamy New England-style shellfish chowder loaded with shrimp, scallops, clams, and crab, thickened naturally with potatoes for ultimate flavor.

- Starch Gelatinization: Mashing the simmered potatoes releases natural starches, thickening the broth beautifully without needing a flour-based roux.
- Residual Heat Poaching: Off-heat poaching ensures the shrimp cook gently, remaining tender and sweet instead of turning rubbery.
- Clam Juice Boost: Utilizing the canned clam liquid infuses the entire base with a deep, authentic, umami-rich ocean flavor.
I still remember sitting on a sun-bleached, splintered dock near the Chesapeake Bay, my knuckles stained yellow with spice as I scraped sweet meat out of crab shells with a dull butter knife. That damp, salty air clings to your skin, and it makes you crave something incredibly rich, warm, and deeply comforting.
This coastal-style chowder is exactly that. It completely skips the heavy, gluey flour paste that ruins so many restaurant versions.
Instead of a traditional roux, we rely on starch gelatinization from the potatoes themselves; as they simmer and break down, they release amylose molecules that naturally thicken the broth into a velvety, luxurious base. This technique keeps the soup light enough that the delicate sweetness of the scallops and shrimp isn't smothered by a thick blanket of flour. If you love this clean approach to seafood, you might also enjoy our light and refreshing Seafood Salad.
It is hands down a triumph of lazy-day cooking.
You start by melting a generous slab of butter in a heavy Dutch oven—my trusty Le Creuset has survived a decade of this—and sweating down the celery and onions until they are completely translucent. When you splash in the dry white wine, the pan will hiss violently, releasing all those caramelized sugars stuck to the bottom.
For the seafood, I always reach for wild-caught shrimp. A high-quality can of chopped sea clams, like Bar Harbor brand, packs a ton of clean ocean flavor.
The real magic happens at the very end when you stir in the raw shrimp, clap the lid on, and pull the pot off the heat entirely. The thermal mass of the hot potato broth gently poaches the shrimp to tender perfection, preventing them from turning into rubbery little erasers.
Shellfish Chowder
Ingredients
- 1 cup finely diced celery
- 1 large onion, chopped
- 1/2 cup butter
- 2 cloves garlic, minced
- 1/2 cup dry white wine
- 2 cups water
- 2 bay leaves
- 3 teaspoons salt
- 1 teaspoon pepper
- 8 cups diced, peeled potatoes
- 2 cups half & half
- 1/2 lb scallops
- 1 6-oz can chopped sea clams
- 2 cups lump or imitation crab
- 3/4 lb shrimp, peeled
- 1 tablespoon hot sauce
Directions
- Melt the butter in a large, heavy-bottomed pot or Dutch oven over medium heat. Toss in the diced celery and chopped onion, cooking for about 5 minutes until they soften and become fragrant.
- Pour in the dry white wine to deglaze the pot, using a wooden spoon to scrape up any browned bits clinging to the bottom. Let the wine simmer and bubble away until it has reduced by at least half.
- Tip the diced potatoes, water, bay leaves, salt, and pepper into the pot. Bring the liquid to a rolling boil, then cover with a tight-fitting lid, drop the heat to low, and let it simmer gently for 20 to 30 minutes until the potatoes are completely tender when pierced with a fork.
- Remove the lid and use a potato masher or the back of a large spoon to crush the potatoes directly in the pot. Stir thoroughly until you have a thick, rustic base with only small potato chunks remaining.
- Pour in the half & half, the chopped sea clams along with their canning juice, the scallops, and the crab meat. Stir gently to combine, bring the mixture back up to a bare simmer over medium-low heat, then cover and cook for 5 minutes.
- Fish out and discard the bay leaves, then take a quick spoonful to taste the broth, adjusting the salt and pepper to your liking.
- Stir in the peeled shrimp and the hot sauce, then immediately remove the pot from the heat source. Cover tightly with the lid and let the chowder rest undisturbed for 15 minutes, allowing the residual thermal mass to gently cook the shrimp until they are pink and curled.
- Ladle the hot chowder into bowls and serve with an extra splash of hot sauce or a delicate drizzle of dry sherry.
Notes
Keep these essential tips in mind to ensure your coastal chowder turns out perfectly velvety every single time:
- Salt Conversion: We developed this recipe using Diamond Crystal Kosher Salt. If you are using standard table salt, cut the measurement in half (use 1.5 teaspoons instead of 3) to avoid over-salting.
- Starch Science: The potato starch acts as a natural emulsifier. Mashing the potatoes releases amylose, which binds the water and dairy fats together, preventing the half & half from curdling when simmered.
- Prevent Scorching: Watch your heat when reducing the wine and simmering the potatoes. Because the water level might not fully submerge the potatoes, stir occasionally to prevent the bottom layers from catching and scorching on the base of your Dutch oven.
- Scallop Prep: If using sea scallops, pat them dry with a paper towel and cut them into bite-sized quarters if they are large. This ensures they cook evenly in the brief 5-minute simmer.
- Storage Rule: Store leftovers in an airtight container in the fridge for up to 2 days. Do not freeze this chowder, as the freezing process breaks down the starch matrix in the potatoes, causing the dairy to separate and turn grainy upon thawing.
Serving Suggestions
To balance the rich, velvety texture of this coastal soup, pair it with sides that offer sharp acidity or a satisfying crunch:
- Warm, crusty bread like The BEST Bread Machine Italian Bread, perfect for wiping down the bottom of the bowl.
- A crisp, green salad tossed with a bright, acidic dressing like Summer Salad Vinaigrette and Marinade to cut through the dairy richness.
- Oyster crackers or saltines crushed over the top to add a salty, brittle crunch to every spoonful.
- A side of golden, savory muffins like Cheddar Cheese Muffins to complement the sweet seafood notes.
- A splash of dry Spanish sherry stirred directly into your bowl at the table for a sharp, complex finish.
Storage and Reheating
Seafood is notoriously finicky when it comes to leftovers, but this chowder actually develops deeper flavors after 24 hours in the refrigerator. The starches and dairy meld together, and the seafood infuses the liquid even further. Keep it in a tightly sealed glass container for no more than two days.
When you are ready to reheat, avoid the microwave at all costs. The intense, uneven electromagnetic waves will overcook the shrimp and scallops, turning them rubbery and tough while potentially breaking the delicate dairy emulsion.
Instead, empty the cold chowder into a small saucepan and place it over low heat. Stir constantly and gently, allowing the soup to warm up gradually without ever reaching a boil, which would cause the half & half to curdle.
If the starch has tightened up the soup too much overnight, simply whisk in a tablespoon or two of whole milk or water to restore its original, velvety consistency.
Ingredient Substitutes
If you need to swap ingredients based on what is fresh at your local market, use these direct conversions to keep the recipe balanced:
- Half & Half → Heavy Cream and Whole Milk: Use a 1:1 ratio (1 cup heavy cream and 1 cup whole milk) to maintain the exact fat content, but lower your stove heat slightly to prevent the heavier fat from separating.
- Dry White Wine → Seafood Stock with Lemon: Swap 1/2 cup wine for 1/2 cup seafood stock mixed with 1 teaspoon of fresh lemon juice to mimic the acidity, adding it at the same step to deglaze the pan.
- Lump Crab → Imitation Crab (Surimi): Swap 2 cups lump crab for 2 cups chopped imitation crab at a 1:1 ratio, but fold it in gently at the very end of the simmer since surimi is already fully cooked and breaks apart easily.
- Scallops → Firm White Fish: Swap 1/2 lb scallops for 1/2 lb diced cod or halibut at a 1:1 ratio, cutting the fish into 1-inch chunks and simmering for an extra 2 minutes to ensure the fish flakes easily.
There is something incredibly satisfying about watching a pot of simple ingredients transform into a rich, coastal feast. Pulling this together on a chilly evening brings a little bit of the salt-air magic right into your kitchen.
