Dungeness Crab Melt
Published October 9, 2026 · Oregon
Search the Oregon newspaper archive for this sandwich and the first thirty-five years of hits are the word Melt beginning the next sentence of a recipe for something else.
Historic Oregon Newspapers sits behind a bot challenge and answers only a real browser, so the counting here was done in one. The phrase "crab melt" returns 36 pages, and the early ones dissolve as soon as you read them, which is the whole lesson of searching for a young dish by name. The Oregon Statesman of 15 April 1938 is a hit because a recipe headed STUFFED CRAB is followed by the line "Melt two tablespoons of butter". The Capital Journal page of 17 May 1956 does not contain the phrase at all. Nebraska's archive does the same thing three times over, and its earliest hit, in a North Platte paper of 9 March 1920, is a recipe titled "Mock Crab" whose method opens "Melt four tablespoonfuls of butter". The first page I could verify as the sandwich is the Daily Astorian of 1 May 2015, in a list of food vendors, where a stand called Crabby Addies is down for "a seasonal variety of fish and chips, clam chowder, seafood bisque, crab melts". This dish has no old document and nobody should pretend otherwise; the quantities below were worked out for this page.
What Oregon does have on paper, in quantity and in detail, is the animal. On 27 May 1909 the Tillamook Headlight printed the text of "An Act to provide for the protection of crabs, razor clams and crawfish" — the column runs interleaved with a piece about the Tillamook salmon hatchery in the scan, so it has to be unpicked line by line — and its sections make it unlawful to take crabs for canning or shipping out of the county in which they are taken during July, August and September, or to take for sale or canning "any male or female crab measuring less than six inches across the back". A century later the rule is stricter and much more exactly drawn. OAR 635-005-0495 makes it unlawful to take, land or possess for commercial purposes "Female Dungeness crab" at all, or a male under six and a quarter inches "measured the shortest distance through the body of the crab from edge of shell to edge of shell from directly in front of the tenth anterolateral spine". OAR 635-005-0465 closes the ocean and the Columbia from 15 August until one minute before nine on the morning of 1 December, and allows that opening to be pushed back on the results of crab quality testing. That testing is the reason a crab melt made in December is a different sandwich from one made in September, and it is all written down.
Why this version works
Salt is already there three times over. The same records put 378 milligrams of sodium in a hundred grams of cooked Dungeness crab, 654 in cheddar, 635 in mayonnaise and 602 in french or sourdough bread. Four salted things in a four-part sandwich. This recipe therefore adds no salt at all to the crab mixture, and the seasoning it does add is the 1938 one: Worcestershire and cayenne, out of George Rector's stuffed crab in the Oregon Statesman, which seasoned a pound of crab with half a teaspoon of salt, a few grains of cayenne and a teaspoon of Worcestershire sauce, and no other seasoning at all.
Grated young cheddar melts; a prize wedge breaks. The standard for cheddar at 21 CFR 133.113 allows a "maximum moisture content is 39 percent by weight" with a "minimum milkfat content is 50 percent by weight of the solids", and a long-aged wedge sits at the dry end of that, which is why it tightens and weeps oil under a broiler. The opposite extreme is written down too: pasteurized process cheese, 21 CFR 133.169, is made "by comminuting and mixing, with the aid of heat" one or more cheeses "with an emulsifying agent" into "a homogeneous plastic mass" — which is why a slice of it melts flat and never breaks. A mild to medium block cheddar, coarsely grated, sits between the two and is the right choice here.
The season is a quality test, and the number is 23 percent. Before the commercial season opens, Washington, Oregon and California run a joint test fishery and pick the catch to see how much meat the crabs are carrying. The Pre-season Testing Protocol for the Tri-State Coastal Dungeness Crab Commercial Fishery, incorporated into Oregon rule by reference, sets the bar for a 1 December opening at "Meat recovery rate for each test area to reach 23 percent (no rounding)" north of Cascade Head and 24 percent south of it. The method is specified down to the brine: "Crab meat will be picked out, including tips. Crab meat will be brined in a 90% solution, cleaned, rinsed, drained, pressed, drip tested and weighed to obtain packed weight", and then "Packed weight is divided by boat weight". A crab that has recently moulted fails that test because it is carrying water instead of meat — which is exactly what goes wrong in the pan when you buy the wrong crab.
Crab brings no fat at all, so the fat has to arrive with it. The USDA record for Dungeness crab cooked by moist heat is 22.3 grams of protein and 1.24 grams of fat per hundred grams. Nothing else on the plate is that lean. That single number explains the whole construction of a melt: mayonnaise, which by federal definition "contains not less than 65 percent by weight of vegetable oil" (21 CFR 169.140), and cheddar, at 34.0 grams of fat per hundred, are not indulgences bolted onto the crab but the only fat in the dish. Leave them out and you have wet protein on toast.
Ingredient notes
The crab: a pound of picked meat, which is roughly two whole cooked Dungeness crabs of two pounds each — the tri-state test fishery's own arithmetic, picking about a quarter of the live weight out as meat. Buy it cooked and picked from a counter that will tell you when it was cooked, or buy whole cooked crabs and pick them yourself for better meat and bigger lumps. Pasteurised tubbed crab works and tastes flatter. Keep the body meat and the leg meat separate as you pick: the leg meat is what you want visible on top.
The mayonnaise: a third of a cup, and no more, for a whole pound of crab. The point of it is adhesion rather than flavour — enough oil and egg to make the meat hold together under cheese and not slide off the toast. Shop mayonnaise is fine and is the thing the standard describes. If you want the lemon brighter, add the juice but not more mayonnaise, because a wet binder and a wet crab make the same failure twice.
The bread and the cheese: four thick slices of a real sourdough or other sturdy white loaf, cut about three quarters of an inch, and four ounces of mild to medium cheddar grated on the coarse holes. A thin or soft slice collapses into the crab; a sandwich loaf goes to paste. Grate the cheese rather than slicing it, so it melts evenly in the two to four minutes the crab needs, and spread it right out to the crust, because an exposed edge of toast burns under a broiler before the middle is hot.
Draining it is not optional: crab meat is 73.3 percent water by the USDA figure, and raw crab 79.2 percent, so there is always free liquid in the tub and it is the single thing that ruins this sandwich. The state protocol drains and presses its samples before weighing and records an explanation if the crab sat draining longer than thirty minutes. Do the same for ten: tip the meat into a sieve, press it gently with the back of a spoon, and leave it over a bowl while you grate the cheese.
Step by step
- Drain and press the crab. Tip the picked crab into a sieve set over a bowl, press it lightly with the back of a spoon, and leave it to drain 10 minutes. Pick through it for fragments of shell and cartilage while it sits, keeping the long pieces of leg meat aside. Do not rinse it: the liquid is salty, but water takes the flavour with it.
- Mix the binder, then fold. Stir the mayonnaise, lemon juice, Worcestershire, cayenne and the chopped celery and chives together in a bowl first, so you are not working a stiff mayonnaise through delicate meat. Add the drained body crab and fold it twice, no more. Taste it before you think about salt, and expect not to need any.
- Toast the bread dry on both sides. Heat the broiler with the rack about 4 inches below it. Toast the slices on both sides under it, or in a toaster, until they are dry and just coloured. Butter them very lightly. Toasting both faces is what keeps the under side from going soft while the top is cooking.
- Build it edge to edge. Divide the crab mixture over the four slices, right to the crust, then lay the reserved leg meat on top. Cover each one completely with the grated cheddar, again to the edges. A bare corner of bread is the thing that burns.
- Broil 2 to 4 minutes and watch it. Slide the tray under the broiler and do not walk away. The cheese should blister in patches and just begin to run down the sides. Two minutes is usually enough with a hot broiler; four is the limit. What you are heating is already cooked, so the only question is the cheese.
- Rest one minute, then cut. Let the melts sit for a minute off the heat before moving them, which lets the cheese firm enough to hold the crab when the knife goes through. Cut each slice once on the diagonal and serve with a lemon wedge.
Everything that goes wrong here is water. If the crab mixture looks slack in the bowl, stop and drain it again in the sieve — once it is on the bread you have no way to take liquid out, and the toast will be a flat wet sheet under a crust of cheese. If the sandwich has already come out soggy underneath, rescue the top: lift the crab and cheese off with a spatula onto a fresh slice of hot dry toast and eat it immediately. A second failure is burnt crust with cold crab in the middle, which means the cheese did not reach the edges or the rack was too close; drop the rack an inch and spread the cheese out. The one unfixable fault is overcooked crab, which goes stringy and smells of ammonia. The meat went into the sandwich already cooked, so anything beyond four minutes under the broiler is cooking it twice.
Storage and make-ahead
Picked crab meat keeps 2 days refrigerated, covered, in a container set over a little ice if you have room, and it should smell of the sea and nothing else. Mix it with the mayonnaise no more than a few hours ahead — the salt in the dressing draws more water out of the meat the longer it sits, and by the next day the mixture is loose. If you have crab to keep longer than two days, freeze it in its own liquid in a tub; it comes back acceptable for a melt, where it would be wasted in a salad.
Do not build a melt to eat later. The sandwich is a four-minute assembly of three things that all keep separately: drained crab mixture in the fridge, cheese grated in a bag, bread sliced. Assemble and broil to order. A reheated crab melt is the dish's worst version, because the second pass through the heat is the one that overcooks the crab.
What to serve with it
Nothing rich. The melt carries about 29 grams of fat a serving on its own, so what it wants beside it is sharp and cold: a green salad with a lemon dressing, a handful of radishes, or a pile of pickled vegetables. Potato chips are honest with it and chowder is not — two dishes of the same seafood and dairy at once is too much of the same thing.
To drink, something acidic and dry. A cold dry white does the same job as the lemon wedge, and so does iced tea without sugar. If it is December and the season has just opened, the better use of the first crab of the year is to eat it cracked and cold; the melt is what the second crab is for.

Questions readers ask
Can I use another crab?
Yes, and it will be a different sandwich. Dungeness leg meat comes out in long sweet pieces that sit up under the cheese; blue crab and snow crab are finer and flakier and disappear into the mayonnaise, and king crab is coarse enough to need cutting. Imitation crab is surimi, mostly fish paste and starch, and it goes rubbery under a broiler. Whatever you use, the drain and the press stay the same.
How do I know the crab is any good?
Buy it in season and ask when it was cooked. The season exists because of meat yield: the tri-state test fishery picks sample crabs before the opening and the states hold the fishery shut until each test area reaches 23 percent meat recovery north of Cascade Head and 24 percent south of it, no rounding allowed. A crab that has recently moulted is below that line — the shell is soft, the weight is water, and the meat shreds. In the shop the signs are a hard shell, real heft for the size, and meat that comes out of the leg in one piece rather than in threads.
Why is the crab from the store always male?
Because the law says so. OAR 635-005-0495 makes it unlawful to take, land or possess female Dungeness crab for commercial purposes at all, and males under six and a quarter inches across the shell, measured "from directly in front of the tenth anterolateral spine". Oregon has been protecting this animal since at least the act printed in the Tillamook Headlight on 27 May 1909, which set the limit at six inches and applied it to both sexes. Everything in a commercial crab counter is a legal-sized male.
What is domoic acid and does it affect what I buy?
It is a toxin produced by a bloom of marine algae, it concentrates in crab, and Oregon rule sets the thresholds precisely: a biotoxin management zone is designated and landings restricted on "a single crab sample result at or above 20 ppm in the meat", with a separate rule for crab testing at or above 30 ppm in the viscera but under 20 in the meat. Closures and zone-by-zone delays are announced publicly, and commercial crab on a counter has come through that testing. The only crab it leaves you to think about is crab you catch yourself, which is why the state publishes the current closures before each season.
