Preheat the Uuni portable wood fired oven for 15 minutes. Place the Uuni Sizzler cast iron grill pan inside the oven to preheat.
Rub the steak with a thin layer of oil. Use a pice mill to break down the Cattleman’s Grill California Tri-tip Seasoning into a finer dust. Season the steak with the rub.
Place the steak in the sizzler pan. Slide into the oven. Cook until the top is nicely browned. Flip. Continue cooking until the internal temperature reaches 125ºF. Remove from the oven and pan.
