Who could be sad when there’s steak to be had! Add a little chimichurri and there goes all your worries!
Set up your immersion circulator and begin heating the water to a temperature that is 2°F (1°C) higher than your preferred doneness temperature. A great water temperature for medium-rare meat is 135°F (57°C).
Season your tri-tip generously. Place it in a vacuum-sealing bag and seal it. (If you don’t have a vacuum sealer, see the alternative method below.)
While the meat cooks in the bath, preheat your grill for direct-heat cooking. Also, prepare an ice bath by filling a large bowl with ice and adding cold water up to the ice level.
Remove the meat from the vacuum bag and place it on the hot grill. Sear each side for 1–2 minutes until good grill marks form. Remove from heat, slice, and serve!
Preheat your pellet grill to 250°F, set up for smoking. Smoke the tri-tip on the second shelf of the grill until the internal temperature reaches 110°F. Remove from the grill and cover loosely with foil.
Increase the grill temperature to 500°F. Remove the door from your two-piece diffuser (or remove the entire diffuser).
Replace the grates, positioning the Grill Grates directly over the firebox. Once the grill is ready, sear the tri-tip, slice, and serve!
