I want to slow cook a Beef Round Sirloin. I have two pieces, one is 3.77 lb and the other is 4.97 lb. I am going to cook them in the same pan at the same time. How long would you recommend I cook it? And at what temperature? Thank you.
For me, roast beef is done when I stick the fork in it and it falls apart on it's own. I cook it in water as usual with packets of onion soup mix and a can of mushrooms at 350 for the first while then turn it down to 300 or lower and let it slow cook til it falls apart.
