How to cook lean beef joint

[Thisoldheartofmine]

I picked up this joint yesterday in co op supermarket.
It was reduced and had 2 yellow stickers on it . I have tried to remove carefully to reveal joint type and cooking instructions , but failed.
I want to cook it to have with salad and possibly for sandwiches and really want it to be tender .
Could someone tell me how best to achieve this?
I only have an oven and hot plates, no slow cooker or anything else .
🙏

It looks like a rolled piece but seems like one solid joint

Anyone ?

Looks like a layer of fat that should be top side when you roast it - baste a few times so it doesn't dry out

Hum it could be topside

Weigh it - I don't cook much meat ( this is more a bump for you ) but would guess 180 for 20 mins a pound plus 20 mins s

Thank you @greencartbluecart . I'm wondering if I can sear the outside in a frying pan and then pot roast it with liquid in the oven
But I think that's for brisket and meat with some fat content.

I would sear it in a dry frying pan. Then wrap it tightly in foil and cook as PP says for about 20 minutes a pound plus 20 minutes. I have done this with a very lean fillet of beef. It comes out very tender but it must be wrapped tightly in the foil. I would agree with 180 but mines a fan oven.

Brilliant @CombatLingerie . Thank you.
Good to know that there's two of us not watching the football. 😀

Yes @Thisoldheartofmine you and I must be the only ones! Just going to watch the Great British Sewing Bee now the football is finished. I was kind and let DH watch the footy on the big telly 😂.
