How to Cook Roast Beef In Slow Cooker

How to Cook Roast Beef in a Slow Cooker.  Hot Roast Beef Sandwiches is one of my favorite meals. It’s super easy to prepare and it’s delicious.  It’s a perfect weekend Slow Cooker (Crock Pot) Recipe. 

When I make it I buy either Boar’s Head or Dietz & Watson London Broil Roast Beef from my local deli.  There are other brands such as Greenridge Farm or Applegate, but they don’t sell them in my area.

So, get whatever kind of London Broil Roast Beef your local deli has.  I get 2 lbs. of London Broil Roast Beef meat for a family of four. London Broil Roast Beef can be a little pricy, so if you’re on a budget Top Round or Bottom Round Beef are also great choices.

Be sure to get it sliced medium thickness, to thin it will fall into small pieces while cooking. While at the deli I also get some provolone cheese.  My family likes the provolone cheese, but you can use any kind of cheese your family enjoys.

How to Make a Roast Beef Sandwich 

Starts with deli Roast Beef and then the bread is the next important step to a Delicious Hot Roast Beef Sandwich. The bread I use and recommend is either a Kaisar Roll or French Bread.

Use a roll with a hard-crusty outer layer so the sandwich doesn’t get soggy and fall apart.  Other types of bread are:

  • Onions Roll
  • Kaiser Roll
  • Baguette
  • Choripan
  • Bolillo
  • Ciabatta
  • Sourdough


Pour Bistro Au Jus Sauce on the bottom of the Slow Cooker (Crock Pot) first.  Place the Roast Beef deli slices in the Slow Cooker (Crock Pot) one piece at a time.  Place the sliced onions and garlic on top of the meat. Pour the rest of the Bistro Au Jus Sauce on top to cover everything.

Cook for about 2 to 2-1/2 hours depending on how much meat you have.  You want the Roast Beef to be brown and the gravy to soak in.
