The tomato-based clam chowder emerged in the 1890s among Italian immigrant cooks on the New York-New Jersey coast, who treated chowder the way they treated zuppa di vongole — tomato broth, no dairy. The 'Manhattan' label was applied by New England partisans as a slur in the early 20th century and stuck. In 1939 a Maine legislator introduced a (failed) bill to make tomato in clam chowder a punishable offense — the rivalry was real. Today it's standard at NJ Shore diners and Manhattan seafood restaurants alike.
Tomato-based chowder from 1890s Italian immigrant cooks on the NY-NJ coast — they treated chowder like zuppa di vongole, no dairy. The 'Manhattan' label was a New England slur that stuck. In 1939 a Maine legislator introduced a bill to make tomato in chowder a punishable offense.
A tomato-red broth, brothy not creamy, full of cubed potato and tomato pulp. Clams are tender, smoky-briny against the sweet-acid base; celery and onion stay distinct. Each spoonful is briny first, vegetal second. Black pepper is forward. Saltines crumbled on top is the diner move. The first time a New Englander sees this they will tell you it isn't chowder — it is, just a different lineage.
The trick is keeping the soup brothy: no dairy means no thickener except the potato starch and tomato pulp. Cherrystone or littleneck clams are chopped, not minced — texture matters. The clam liquor (the natural juice from steaming) carries more flavor than any stock; using it is the difference between a chowder and a tomato-vegetable soup. Bacon adds smoke and fat without dominating. Add the clams last, briefly, or they go rubber.
Variations
Rhode Island clear (clam-broth-only, no tomato, no cream — Champlin's Seafood); New England creamy (Legal Sea Foods); Manhattan tomato-based; Minorcan-style St. Augustine FL adds datil pepper; Hatteras NC version uses no dairy and no tomato.

How it's made
5 steps · 50 min active + 10 min waiting
- 115 min
Scrub 1.5kg live hard-shell clams (cherrystones or littlenecks). Steam in 250ml water in a covered pot 5-7 minutes until shells open. Discard any unopened. Strain liquor through cheesecloth — reserve. Pull meat from shells; chop coarsely.
Watch outThe strained clam liquor is the soup's backbone — don't pour it down the drain.
- 28 min
Render 100g diced bacon or salt pork in a heavy pot over medium-low until crisp. Remove solids; leave fat. (Some classic NY versions skip the pork — a New Jersey 1939 law tried to make this version mandatory.)
- 310 min
Add 1 large onion, 2 celery ribs, 1 carrot — all small-diced. Sweat 8 minutes until soft, not brown. Add 3 minced garlic cloves, 1 tsp dried thyme, 1 bay leaf; cook 1 minute.
- 425 min
Add 800g canned crushed tomato (San Marzano), the reserved clam liquor, 500ml fish or chicken stock, and 600g peeled potato (Yukon Gold) cut in 1cm dice. Simmer 20 minutes until potato is tender.
Watch outDon't add the clams yet — they'll go rubbery if cooked twice.
- 53 min
Stir in chopped clams, the reserved bacon, 1 tsp Worcestershire, salt and black pepper to taste. Heat through 2 minutes — no longer. Finish with chopped flat-leaf parsley.
Watch outOnce clams hit hot soup they have 2 minutes before they seize — pull as soon as warmed through.
