Remove picanha roast from packaging and pat dry with a paper towel.
Place roast meat side up on your cutting board and carefully trim off any loose fat and silverskin.
Slice the meat with the grain to create 3–4 individual steaks.
Season each steak liberally with salt and pepper and let sit for 15–20 minutes.
Skewer the steaks one by one with your rotisserie spit. If your spit rod is too thick to go in on its own, use a sharp knife to pierce an opening in the meat for it to slide into. Once all pieces of meat are on, secure the rod to your rotisserie.
Insert an RFX™ MEAT wireless probe into the smallest steak, making sure to reach the minimum immersion line, and cook on the rotisserie. Set the high-temp alarm on your app to 130°F.
Ideally you want to cook at about 250–300°F. (This can be done by adjusting the fire or heat level of your grill.)
Cook until your RFX alarm sounds in your app. Rest the meat and serve!
