  • 1kg beef topside
  • 2 cloves garlic, cut into slivers
  • olive oil
  • 2 onions, halved and sliced
  • 500ml American pale ale
  • 2 bay leaves
  • 6 black peppercorns
  • 4 sub rolls or long soft rolls, halved
  • for spreading Dijon mustard
  • 16 slices emmental


  • STEP 1

    Heat the oven to 150C/fan 130C/gas 2. Heat an ovenproof casserole. Make incisions all over the beef with a small, sharp knife and push in the slivers of garlic. Rub the topside all over with oil then season well.

  • STEP 2

    Put in the pan and brown on all sides, until it has a really deep colour. Spend a bit of time doing this, as it will all help the flavour of the gravy. Lift out of the pan and add the onions with a pinch of salt. Cook on a fairly high heat until the onions have started to break down and turn golden. Add the beer and bring to a simmer. Add back the beef with the bay and peppercorns and cover with a lid. Transfer to the oven for 3 hours.

  • STEP 3

    Take the beef from the gravy, trim away any fat or other straggly bits, cool to room temperature and chill for 2 hours (this will make it easier to slice, see note). Once chilled, slice the beef as thinly as possible. Strain and warm the gravy, before serving.

  • STEP 4

    Warm the rolls in a low oven, then split and spread thinly with mustard. Drop the beef into the gravy for a few minutes to reheat then stuff it into the baguettes along with a few slices of cheese. Serve the rest of the gravy on the side in bowls for dipping.

Cooking then chilling the beef is a trick that delis use, which makes it so much easier to slice the meat thinly. A couple of hours is enough but you could also make this a day ahead, and chill overnight, just make sure you chill the gravy too.
