Minute Steak Sandwich with Diane Sauce

A minute steak sandwich with Diane sauce is the perfect balance of quick cooking and indulgent flavour. Thin, tender steak seared hot and fast, tucked into rustic bread, and finished with a silky Diane sauce made from brandy, cream, and mustard — it’s a showstopper of a sandwich that feels both comforting and luxurious.

INGREDIENTS

For the Sandwich

  • 2 Native Breed Beef Minute Steaks (about 500g total)
  • 2 rustic sandwich rolls or slices of crusty bread
  • 1 tbsp olive oil
  • Sea salt and freshly ground black pepper
  • Butter for spreading
  • Optional: rocket leaves or watercress

For the Diane Sauce

  • 1 tbsp butter
  • 1 shallot, finely chopped
  • 1 garlic clove, crushed
  • 100ml brandy (or cognac)
  • 1 tsp Dijon mustard
  • 150ml double cream
  • 1 tsp Worcestershire sauce
  • 1 tsp freshly cracked black pepper
  • 1 tsp chopped fresh parsley
  • Pinch of sea salt
METHOD

Step 1: Prepare the Steaks

  1. Pat the steaks dry and season well with salt and pepper.
  2. Heat a heavy-based frying pan over high heat with the olive oil.
  3. Cook the steaks for 1–2 minutes per side until seared and just cooked through. Remove and rest.

Step 2: Make the Diane Sauce

  1. In the same pan, melt the butter and add shallots. Cook until soft and translucent.
  2. Add the garlic and cook briefly.
  3. Pour in the brandy and carefully flambé or simmer until reduced by half.
  4. Stir in mustard, Worcestershire sauce, and cracked black pepper.
  5. Add cream and simmer until thickened slightly.
  6. Finish with chopped parsley and adjust seasoning.

Step 3: Assemble the Sandwich

  1. Slice open the bread and lightly toast or warm if desired.
  2. Spread a thin layer of butter on the bread.
  3. Place the rested minute steak onto the bottom slice.
  4. Generously spoon the Diane sauce over the steak.
  5. Add optional rocket or watercress for freshness.
  6. Top with the other slice of bread and serve hot.

Hot Tips

  • Make sure your pan is very hot before adding the steaks — they should sear quickly without overcooking.
  • Rest the steak briefly before slicing to keep the juices locked in.
  • Use a sturdy rustic bread that can hold the sauce without going soggy.
  • If flambéing the brandy, tilt the pan slightly away from you and ignite with care.
  • Don’t let the cream boil too hard — keep it to a gentle simmer for the best texture.
