Roast Beef Help!

[Wilberforce2]

Help! In-laws coming for dinner today (this only happens about 4 times a year) and have requested roast beef because I always do lamb apparently Dh went out yesterday and bought a 1.8kg silverside I think. I never cook beef, I don't eat red meat and we just never have it, I'll cook lamb when we have people over (not that I eat it) and other times we just have chicken.

So does anyone have any tried and tested ways to make this beef taste amazing? Dinner isn't until 4pm so I have time, there are so many recipes on google but I'd like someone to recommend one. I can't mess it up!! It mustn't be well done either 🤷‍♀️

Thanks!!

Silverside is best pot-roasted or roasted in the oven with some liquid in the roasting tray so that steam is created to keep the joint moist.
Rub the joint with butter and sprinkle with plenty of salt and pepper.
Place in the centre of the oven and roast for 20 minutes, then reduce the temperature to 170°C for fan assisted or 180°C for ovens without a fan. Add 100ml of water, 4 chopped red onions and 4 cloves of garlic, quartered. Continue roasting for 20 minutes per 500g for a medium rare roast, basting from time to time and adding a little more water if necessary. This will keep the meat moist. Re-cover with the foil each time. Uncover the meat for the last 15 minutes of cooking.
Don't forget to rest your joint for at least 20 minutes before serving.

@Ricekrispie22 has given great advice! I would also add shallots to the tin. Use the juices at the end for the gravy with a good glug of red wine.

Thank you SO much this is exactly the kind of reply I was hoping for! Going to follow this to the letter and hopefully I'll get it right. x
