Step 1

Mix together the rub ingredients and rub all over the rump roast.  If you have another dry rub that you like for beef, go ahead and substitute, you won't hurt my feelings.  Truth be told, it doesn't really need it but it feels funny to me not to rub it with something.

Step 2

Thread the roast beef onto the rotisserie, right down the middle and make sure you secure it with the forks so that the spit is locked into the rump roast.

Step 3

Configure your grill's rotisserie per the owner's manual.  Another great thing about my new baby (grill) is that it has a built-in smoker box with a dedicated burner.  I like to add smoke to the chamber while I am cooking the rotisserie roast beef.  If you don't have a smoke box and want to add some more flavor, throw together a smoke pouch and get it smoldering before you put the rotisserie on the grill.

Step 4

Make sure you place a pan under the roast to catch those drippings!

Step 5

Turn on the rotisserie motor and sit back while your rotisserie roast beef slowly roasts on the grill.  This is so easy, right?

Step 6

After about an hour, check the internal temperature of your roast with a meat thermometer.  I'm not even going to suggest a time because there are so many variables here.  As a reference point, a 4.5 pound rump roast takes about an hour and a half on my rotisserie set up.

Step 7

Roast the rotisserie beef until you hit the desired doneness.  I like mine medium-rare, so I roast the rump roast until 140 degrees.  Remember that the roast will continue to cook for a little while once removed from the heat, so take it off about 5 degrees shy of your desired temperature.

Step 8

Remove the rotisserie roast beef from the grill, place on a platter and cover with aluminum foil to rest for about 15 minutes.

Step 9

While the roast is resting, make a rue using about 2 tablespoons of butter and about a tablespoon of flour (look for directions online if you haven't made gravy before).  Stir in the roast beef drippings and beef brother as needed to make some awesome gravy!

Step 10

Carefully remove the rotisserie spit from the roast and slice thinly, against the grain, for maximum tenderness.
