This is maybe more pot roast than roast beef (is there a difference?)
I take a 2.5-3 LB bottom roast and rub it all over with salt, pepper, paprika, cayenne, and garlic powder. Then I brown the sides in a frying pan with some olive oil.
Next, chop up a bunch of carrots and celery and put them in the bottom of the crock pot. Then put in the roast, and on top throw in a chopped onion. Then add one can (15 oz.) of tomato sauce (I use Muir Glen Organics- no added sugar.)
Put the crock pot on high for one hour (to warm it up), then on low for 7 hours. It comes out perfectly for me every time!
