Remove the tri tip from refrigerator and allow to come up in temperature about 30 minutes while you prepare other ingredients.
Combine the spices and season the tri tip steak liberally on all sides.
Heat a large cast iron skillet over medium high heat add avocado oil. Place tri tip in skillet and brown on all sides, 3-4 minutes per side.
Turn heat down to medium and cook tri tip for about 5-7 minutes on each side, flipping every 3-4 mintues.
When the meat reaches an internal temperature of 125-126ºF (for medium) add in butter, garlic, shallots and rosemary. With a spoon, spoon the melted butter over the roast as it continues to cook and come up to temperature.
Remove the roast from the pan once it is 5 degrees below your desired doneness, see post above. For this recipe the roast was cooked to 130ºF
Allow the roast to rest for at least 10 mintues before slicing against the grain.
