This is not your grandma’s Sunday pot roast, it’s even better. The black pepper and garlic rub adds a delicious crust for the grilled roast beef. If you can add in a little hickory smoke, it’s sure to be one of the best roast beef recipes you will ever try.

Tip for Slicing Roast Beef:

Completely chilled roast will be easier to slice thinly for sandwiches. Slice roast as needed to keep the most fresh tasting meat. Keep tightly wrapped in plastic wrap until ready to serve.

  1. Made this today and it was delicious. I had a 4# roast which took about 45min longer to cook to 140 bit hubby enjoyed cooking it. I did forget the brown sugar but it was still delicious without it. Definitely a keeper
