How to Cook Beef in Crock Pot?
Heat some oil in a heavy skillet and sear (or brown) the meat on all sides. This way the juice is sealed in and blood from the meat won't seep through. You don't want to cook the meat in its own blood. Place the browned meat in the crock pot, fat side up. Put lid on and let it cook for 6 to 8 hours depending on the size of meat.
If you want the meat to be fork tender, slice the meat up and place it in a baking dish with its juice then put it in a 325 degrees oven for an hour. Serve with baked potatoes and au jus sauce or thickened gravy.
Put cut vegetables like potatoes, carrots, celery, onions on the bottom of the pot, then place meat on top of veggies. Thicken the meat juice with flour or cornstarch on top of stove for gravy.
