Slow Cooking Instructions for Roast Beef

Updated February 21, 2017

If you're planning a large party or get-together, make roast beef in a slow cooker to save time. You can prepare the roast on the morning of or night before the dinner, and allow the slow cooker to do all the work. A slow cooker will transform a chuck roast into a tender piece of meat that you can slice and serve on fresh buns or by itself. For added convenience, prepare the gravy in the slow cooker as well.

Rinse a 1.81kg. chuck roast and pat it dry with paper towels. Season the roast with salt, black pepper and onion powder to taste.

Place the roast into a 6-quart slow cooker. Pour 1 can of beef broth over the top of the roast. Add 1 28.4gr. package of dry onion soup mix for extra flavour.

Add one diced onion and two peeled garlic cloves to the slow cooker. Include fresh or dried herbs, such as rosemary or thyme, to taste. Stir the ingredients with a wooden spoon to blend.

Cover the slow cooker and set it to "low." Cook the roast beef for eight to ten hours, or until the meat is fork tender.


Cook the roast beef until it has an internal temperature of 62.8 degrees Celsius for medium-rare, 71.1 degrees Celsius for medium and 76.7 degrees Celsius for well-done.
