Can someone please tell me how long to cook this beef for?

[Geepers]

I have a 740 gram top rump beef joint that I need to have ready for 2pm. I am a crap cook and rarely cook meat because it always ends up tough and dry.

I have googled and can't come up with a website that say 'put it in the oven for x amount of time, at x temperature and you will have a perfect lunch'.

What I need to know is:

a) how do I prepare the meat - do I cover it with tin foil, wrap it in tin foil, or leave it open

b) what temperature do I have the oven at. Does it start hot and get turned down? One temperature throughout?

c) most importantly how long do I leave it in the oven for? We like it well done, but not charcoaled which is how it tends to wind up when I have finished with it.

Pleeeeeease help me.

That is quite small so will take about 45 - 60 mins to cook. I would season it and stick it in a very hot oven for 15 mins and then turn the temp down. I would probably throw a glass of wine in the bottom of the tray and cover it in foil. Let it rest for 15 mins when it is cooked before carving.

what temp do I start with, and then turn down to? Red wine or white?

I told you I can't cook, I am so

Start as hot as it will go and then turn down to 130-ish, use red. It will be lovely don't worry throw some onions and herbs (chopped up) in the bottom of the tray with the wine and you will have the makings of a delicious gravy when you have finished cooking.

It's in the oven now but I had to forego on the wine as only had white.

Thank you
