A lower-calorie way to make Bangers and mash
Bangers and mash with lean sausages and proper onion gravy
Two lean pork sausages, milk-mashed potatoes, peas and deeply browned onion gravy make a familiar dinner at about 520 calories per serving.
A lighter plate of bangers and mash should not depend on a tiny sausage or watery gravy. The sausages brown on a rack so their surfaces colour without sitting in extra fat. Meanwhile, the onions cook slowly until genuinely sweet, then release their browned pan residue into stock. Milk and potato cooking water loosen the mash before a small amount of butter is added, so it stays fluffy rather than greasy.
What changes—and what stays
From often 700–900 kcal with fatty sausages, buttery mash and gravy made from drippings to 520 calories
Choose eight sausages at no more than 130 kcal each, bake them on a rack, and use 20 g butter across the entire potato mash. Slowly browned onions, mustard and reduced beef stock give the gravy savoury depth; roasting the sausages creates the browned notes that a larger amount of fat would otherwise supply.

A cost rule that survives inflation
Potatoes, onions and frozen peas are dependable-value staples, while comparing sausages by meat content and nutrition per link avoids relying on a temporary shelf price.
Ingredients for 4
Measure first; timing is part of how this recipe uses less fat.
- 8 (480 g)lean pork sausages
- 900 gfloury potatoes
- 200 mlsemi-skimmed milk
- 20 gbutter
- 500 gonions
- 500 mllow-salt beef stock
- 15 gplain flour

Method
Each step includes heat, a visible cue, and a recovery.
Step 1 · follow the visible cue
Brown the sausages above the tray
Set the sausages on a rack over a lined tray and bake at 210°C for 22–26 minutes, turning once rather than adding oil.
Look for: The skins are evenly chestnut-coloured and the centre reaches 75°C without a pool of fat around each link.
Step 2 · follow the visible cue
Steam the potatoes dry
Simmer equal potato chunks until tender, drain thoroughly and return them to the warm pan uncovered for two minutes before mashing.
Look for: The surface looks floury and no water gathers beneath the potatoes when the pan is tilted.
Step 3 · follow the visible cue
Take the onions beyond translucent
Cook sliced onions in a wide non-stick pan with splashes of stock for 18 minutes, then stir in flour, mustard and the remaining stock.
Look for: The onions are deep amber and the gravy coats a spoon while still flowing rather than sitting as paste.
Step 4 · follow the visible cue
Loosen mash before adding butter
Beat warm milk and 80 ml reserved potato water into the mash, then fold in butter. Divide two sausages, mash, gravy and peas per plate.
Look for: The mash forms soft peaks, the gravy is measured over it, and each plate has a full portion of green peas.

Compare calories and saturated fat per sausage, not just the front-of-pack claim, and keep the planned serving at two links.
Can I use vegetarian sausages?
Yes, but use their label values because protein, salt and calories differ widely between products.
