The dish itself — sausage and potato — was peasant food across northern Europe for centuries. The British naming and pub-menu form date to the early 20th century; "banger" as slang for sausage is World War I trench-era, referring to the way wartime sausages (high water content from rationed meat) split and exploded in the pan. The phrase "bangers and mash" first appears in print in the 1910s.
WWI nickname — wartime sausages had so much water they popped (banged) in the pan. The onion gravy made with the sausage fond is what separates pub from cafeteria.
Two or three thick pork sausages — Cumberland coil, Lincolnshire, or plain pork — split-skinned where they pressed the pan, on a heap of buttery mash with a small lake of dark onion gravy. Mustard on the side. The mash should be loose enough to take the gravy, not stiff. Eaten on a deep plate so nothing escapes the gravy. Pale dry sausages mean the cook didn't render the casing.
The gravy carries the dish, and the gravy is made by deeply caramelising sliced onions in butter for 30+ minutes until they collapse to mahogany — then deglaze with stout or stock, finish with Worcestershire. Quick onion gravy from granules tastes thin. The sausage should be at least 80% meat: the cheap 60% versions weep water and shrivel. Mash with whole milk and butter at a 1:5 ratio by weight to potato, not low-fat.
Variations
Cumberland coil with red-onion gravy; Lincolnshire (sage-heavy) with mustard mash; Glamorgan vegetarian sausage (leek + Caerphilly cheese) is the Welsh bench answer.

Peel and quarter the potatoes. Place them in a pot of salted water and bring to a boil. Cook until tender, about 15 minutes. Drain and return to the pot.
Watch outMake sure the water is at a rolling boil before adding the potatoes to ensure even cooking.
- 25 min
Mash the potatoes with butter and milk until smooth and creamy. Season with salt to taste.
Watch outAvoid over-mashing the potatoes to prevent them from becoming gummy.

In a large skillet, cook the sausages over medium heat, turning occasionally, until browned and cooked through, about 10 minutes.
Watch outBrown the sausages patiently over medium heat, turning for an even deep-gold crust all round — high heat splits the skins and leaves the middle raw.
- 48 min
Slice the onion thinly and cook in the same skillet with a bit of butter until soft and golden. Use the onions to make a simple gravy if desired.
Watch outThe gravy onions are ready when they've cooked right down to a soft, jammy, deep-brown tangle — pale, crunchy onions mean they need much longer.
