Ingredients
Method
- Sear sausages over medium‑high heat until golden, about 7 mins, turning frequently.
- Remove sausages; soften onions in the pan fat for 3 mins.
- Stir in stock and mustard, simmer until reduced, about 2 mins.
- Boil potatoes until fork‑tender (12‑15 mins). Drain well.
- Mash potatoes with butter, warmed milk, and reserved sausage fat.
- Serve sausages on mash, top with onion‑mustard sauce and parsley.
Notes
Reserving pan fat is Ramsay’s trick—adds flavor without extra butter.
