Easy Roast Beef Fillet
Preparation time: less than 30 mins | Cooking time: 30 mins to 1 hour | Serves: 10
For the beef
- 1kg middle-cut thick fillet of beef
- salt and pepper
- 2 tbsp olive oil
For the sauce
- 2 whole heads garlic
- 50ml/¼ pint mayonnaise
- 50ml/¼ pint full fat crème fraîche
- ½ tsp sugar
- 2 tbsp wholegrain mustard
- Preheat the oven to 220C/425F/Gas 7 (fan 200C).
- Rub the fillet of beef with plenty of salt and pepper and the oil.
- Heat a large frying pan until very hot. Fry the fillet on all sides until browned. Transfer to a roasting tin.
- Place the fillet in the centre of the roasting tin, arrange the whole garlic bulbs around the fillet and drizzle with a little oil. Roast for 23 minutes for medium-rare (only 20 minutes if it is a long, thin piece).
- When the beef is cooked, remove from the oven, cover with aluminium foil and leave to rest for 15 minutes.
- Serve hot or you can leave it to cool, and then wrap in more foil and place in the fridge to cool completely.
- To make the sauce, cut the roasted garlic bulbs in half horizontally and squeeze the garlic paste from each single clove into a bowl. Add the mayonnaise, crème fraîche and sugar.
- Blend to a smooth purée using a blender or food processor. Stir in the wholegrain mustard. Chill until ready to serve alongside the beef.
- Carve the beef into thin slices just before serving
