Little dauphinoise stacks
It's easy to make dauphinoise potatoes but why not make them look a bit smarter by giving everyone their own individual cut out stack? You can make this recipe ahead then just cut out and heat the stacks to serve.
Put the steaks on a plate, drizzle with 1 tbsp of oil and season. Heat a non-stick frying pan over a high heat and, once hot, cook the steaks for 3 mins on each side (for medium-rare), then put on a plate, cover and leave to rest.
Tip the shallots into the pan with another drizzle of oil, and cook for 2-3 mins until softened. Add the mushrooms and fry over a high heat until softened and golden. Stir in the peppercorns and wine and continue to cook until the wine has evaporated. Add the stock and simmer until reduced by half. Stir in the crème fraîche and mustard and simmer for 3-4 mins more, then add the thyme.
Tip any resting juices from the steaks into the sauce, then slice the steaks and serve with fries and salad, with the sauce spooned over.
