What are the best clams for New England clam chowder?

Cherrystone or large chowder quahogs are the classic choice: they are tougher than littlenecks but far more flavorful per dollar, and since chowder chops and simmers the meat anyway, tenderness matters less than flavor. Littlenecks work but are expensive for the yield. Canned chopped clams are a genuinely good option — they are pre-cooked, grit-free, and packed in their own juice, so add them at the very end so they don't toughen.

Can I make clam chowder with canned clams?

Yes, and the result is very close to fresh. Use four 6.5-ounce cans of chopped clams plus two 8-ounce bottles of clam juice for a pot that serves six. Pour the canning liquid into the broth for flavor, but hold the clam meat back until the final few minutes over low heat — canned clams are already cooked, and simmering them further makes them rubbery. This version takes about 45 minutes.

How do you thicken clam chowder?

The recipe's built-in thickeners are flour cooked into the pork fat and starch from the simmering potatoes. If the pot is still thin, reduce it uncovered for about ten minutes before adding cream, or mash a cupful of the cooked potatoes against the pot and stir. A kneaded butter-and-flour paste whisked in and simmered a few minutes also works. Aim for a chowder that coats a spoon but still pours — not paste.

Why did my clam chowder curdle?

Almost always because the dairy boiled. Cream and milk can break into a grainy texture when a chowder is boiled hard after they're added, and acidic or very hot broth hitting cold cream makes it worse. Add cream at the end over low heat and keep the pot below a boil from then on, including when reheating leftovers. Letting the cream come toward room temperature while the potatoes simmer adds cheap insurance.

How long does clam chowder last in the fridge?

Cool it within two hours of cooking, refrigerate it covered, and eat it within three to four days. Reheat gently on the stovetop over medium-low, stirring often, until steaming hot but not boiling, and loosen the thickened soup with a splash of clam juice or milk. Freezing is not recommended: cream-based soups tend to separate when thawed and the potatoes turn mealy, so freeze only the clam-and-cream-free base if you want to work ahead.

Should you discard clams that don't open?

Yes. When steaming fresh clams, pull each one from the pot as it opens, and throw away any clam that remains firmly shut after cooking rather than prying it open. Before cooking, check the raw clams too: shells should be tightly closed or should close when tapped, and the clams should smell cleanly of the sea. Any clam with a cracked shell or a sour, off odor should be discarded at that stage.

New England Clam Chowder Recipe: Creamy and From Scratch

Anchor & Hope · Updated 2026-07-19 · 8 min read

The gistNew England clam chowder is a cream-based soup of chopped clams and their briny liquor, salt pork or bacon, onions, celery, and waxy potatoes, thickened lightly with flour and finished with cream over low heat. Steam and chop fresh quahogs (or use canned chopped clams), build a base in the rendered pork fat, simmer the potatoes in clam broth until tender, then stir in the clams and cream at the end — hot, but never boiling, so the clams stay tender and the dairy stays smooth.

What Goes Into a Real New England Clam Chowder

New England clam chowder is a cream-based soup built from five things: chopped clams and their briny liquor, rendered salt pork or bacon, onions and celery softened in that fat, waxy potatoes simmered until tender, and cream stirred in at the end. It is thickened gently — a little flour, plus the starch the potatoes give up — so it coats a spoon without turning to paste. No tomatoes, ever; that's Manhattan's argument to have.

The whole pot takes about 45 minutes with canned clams and closer to an hour if you steam fresh ones. Neither version is difficult. The difference between a forgettable chowder and one worth a second bowl comes down to three decisions: which clams you use, how much you thicken, and whether you boil the cream (don't). This recipe walks through all three.

Clam Chowder Ingredients: What You Need and Why

Every ingredient in a classic chowder earns its place. Here's the shopping list for a pot that serves six, with the reasoning behind each item.

Clams — about 5 pounds of fresh cherrystone or chowder quahogs, or four 6.5-ounce cans of chopped clams. More on this choice below.
Clam juice — two 8-ounce bottles if you're using canned clams; the steaming liquid itself if you're using fresh. This is the backbone of the flavor.
Salt pork or thick-cut bacon — 4 ounces. Salt pork is traditional and purely porky; bacon adds smoke. Both work.
Yellow onion and celery — one large onion, two ribs of celery. The aromatic base.
All-purpose flour — 3 tablespoons, cooked into the fat. This is your primary thickener.
Potatoes — 1½ pounds Yukon Gold or another waxy-to-medium-starch potato, cut in ½-inch dice. They hold their shape and release just enough starch.
Heavy cream — 1½ cups, or 1 cup cream plus 1 cup whole milk for a lighter pot.
Bay leaf, fresh thyme, black pepper — the seasoning stays quiet so the clams lead.
Oyster crackers — not optional in spirit, even if they're optional in fact.

Notice what's missing: no wine, no garlic overload, no cornstarch slurry. Chowder is a plain-spoken dish. Restraint is the technique.

Best Clams for Chowder: Fresh Quahogs vs. Canned

Hard-shell clams (quahogs) are sold by size, and size determines the job. Smaller clams are tender and sweet; bigger ones are tougher but far more flavorful per dollar — and since chowder chops and simmers them anyway, big is what you want.

Clam	Size	Best use	Chowder verdict
Littleneck	Smallest hard-shell	Raw bar, pasta, steaming	Works, but expensive for chopped meat
Cherrystone	Medium	Grilling, stuffing, chowder	Excellent — good meat yield, still tender
Chowder (quahog)	Largest	Chowder, fritters	The classic choice; chewy raw, perfect chopped
Canned chopped clams	—	Chowder, dips	Honest, consistent, available everywhere

If you live near a coast, buy cherrystones or chowder quahogs. Look for tightly closed shells (or shells that close when tapped) and a clean, sea-smell — never sour or ammoniated. Store them in the fridge in a bowl under a damp towel, never sealed in plastic or submerged in fresh water, and cook them within a day or two.

If you don't, use canned clams without apology. Canned chopped clams are cooked, cleaned, and packed in their own juice. Combined with bottled clam juice, they make a chowder most people couldn't distinguish from fresh in a blind spoonful — and they turn this into a true weeknight pot. The one rule: add them at the very end, off a boil, because they're already cooked and will toughen into erasers if simmered.

The Recipe: New England Clam Chowder From Scratch

Serves 6 · About 1 hour with fresh clams, 45 minutes with canned

Step 1: Steam the clams (skip if using canned)

Scrub 5 pounds of quahogs under cold running water. Pour 2 cups of water into a large lidded pot, bring it to a boil, add the clams, cover, and steam for 6 to 10 minutes, pulling clams out as they open. Discard any clam that stays shut after cooking — don't pry it open and hope.

Pull the meat from the shells and chop it roughly. Strain the steaming liquid through a fine-mesh sieve (or a coffee filter) to catch grit — this strained broth is liquid gold, and you should have roughly 3 to 4 cups. Set both aside.

Step 2: Render the pork

In a heavy Dutch oven over medium heat, cook the diced salt pork or bacon until the fat has rendered and the bits are crisp, about 8 minutes. Remove the crisp bits with a slotted spoon and save them for garnish, leaving the fat in the pot.

Step 3: Build the base

Add the diced onion and celery to the fat and cook until soft and translucent but not browned, 6 to 8 minutes. Sprinkle the flour over the vegetables and stir constantly for 2 minutes — this cooks off the raw-flour taste and sets up your thickening.

Step 4: Simmer the potatoes

Whisk in the clam broth (or bottled clam juice plus the liquid from the cans) gradually, so the flour dissolves without lumping. Add the potatoes, bay leaf, and a few sprigs of thyme. Bring to a gentle simmer and cook until the potatoes are tender at the tip of a knife, 12 to 15 minutes. Stir occasionally and scrape the bottom — flour-thickened soups want to stick.

Step 5: Finish with clams and cream

Drop the heat to low. Stir in the chopped clams and the cream and warm everything through for 2 to 3 minutes — hot, but never boiling. A hard boil at this stage can curdle the dairy and will absolutely toughen the clams. Fish out the bay leaf and thyme stems. Taste before salting: between the clams, their liquor, and the pork, the pot may need nothing but a heavy hand of black pepper.

Ladle into bowls, scatter the reserved pork bits and oyster crackers over top, and serve immediately.

How to Thicken Clam Chowder (and How Not To)

Proper New England chowder is creamy but pourable — it should nap the back of a spoon, not stand up like wallpaper paste. If yours came out thinner than you'd like, you have four honest options, in order of preference:

Simmer it longer, uncovered. Ten extra minutes of gentle reduction concentrates flavor and body at the same time. Do this before the cream and clams go in.
Mash some potatoes. Press a cupful of the cooked potatoes against the side of the pot and stir. The released starch thickens naturally with zero added ingredients.
Add a flour-butter paste. Knead a tablespoon each of soft butter and flour together, whisk it in, and simmer 3 to 4 minutes. Reliable and traditional.
A cornstarch slurry (1 tablespoon cornstarch in 2 tablespoons cold water) works in a pinch, but adds a glossier, slightly gelled texture that reads more diner than New England.

And one warning in the other direction: if a spoon can stand up in your chowder, you've over-thickened. Thin it back with clam juice — not water, which dilutes flavor, and not more cream, which dulls it.

Common Chowder Mistakes (and the Fixes)

Rubbery clams. They were boiled after being added. Clams — like shrimp, which have the same short window between done and ruined that we cover in our guide to cooking shrimp — finish in minutes. Add them at the end, over low heat.
Curdled, grainy broth. The dairy boiled, or cold cream hit hot soup too fast. Keep the heat low at the finish; letting the cream sit out while the potatoes simmer helps too.
Gritty bottom-of-the-bowl. Fresh-clam broth went in unstrained. Always pass it through a fine sieve or coffee filter.
Bland pot. Usually under-reduced broth or timid pepper — not missing salt. Clam liquor and pork carry plenty of sodium; brightness comes from black pepper and thyme.
Blown-out potatoes. Russets over-simmered into mush. Use Yukon Golds and pull the pot off the heat when a knife tip slides in easily.

Storage, Reheating, and Making It Ahead

Chowder is better on day two — the flavors settle and round out overnight. Cool it within two hours of cooking, refrigerate in a covered container, and eat it within 3 to 4 days.

Reheat gently, on the stovetop over medium-low, stirring often, until steaming hot — again, not boiling, for all the same clam-and-cream reasons. The chowder will have thickened in the fridge as the starch set; loosen it with a splash of clam juice or milk.

Freezing is the one thing this soup does badly. Cream-based soups tend to separate when frozen and thawed, and the potatoes turn mealy. If you want to work ahead by weeks rather than days, make the base through the potato step, freeze that, and add clams and cream fresh when you reheat.

What to Serve With It

Tradition says oyster crackers, a crusty roll for dragging through the bowl, and not much else — chowder is a complete argument on its own. If you're feeding a crowd and want a second dish that won't compete, something clean and simple from the oven works beautifully; a well-baked side of salmon shares the table without fighting for it. And if this pot gets you hooked on shore-style cooking, the rest of our coastal recipes collection picks up where the chowder leaves off — stews, rolls, and the other classics the boat brought in.

One last note on the dish itself: New England clam chowder isn't a restaurant trick. It's a fisherman's supper — pork fat, potatoes, and the day's clams stretched with milk into something generous. Every shortcut in this recipe that works, we've said so; the only thing you can't shortcut is the gentle heat at the end. Respect that, and the chowder takes care of the rest.
