Preheat oven to 415℉. Make sure your oven rack has enough room above it to place your large pot into, once you're done searing off the the tri tip.
Put a large heavy-bottom pan (oven safe) over medium-high heat. Let pan get hot while you season the tri tip.
Generously season each side of the tri tip with salt, Montreal Steak seasoning, and pepper. Pour 2-3 tablespoons of olive oil into bottom of hot pan. Using tongs, slowly lower the tri tip down into the pan.
Sear on the bottom for 6-8 minutes until dark brown, then sear the top also for 6-8 minutes, and then I like to sear the long side for about 6 minutes as well. Searing all 3 of these sides really holds the juices in.
Once all 3 sides have been seared to a golden brown color, cover the pot and place into preheated oven.
Bake for about 12 minutes per pound, but use the temperature guide below to determine how done you'd like your meat:- Medium: 140-145℉- Medium Well: 150-155℉-Well Done: 160-165℉ Once allotted time is done, use your meat thermometer in the thickest center part of the meat to determine temperature.
Once you've reached your desired temperature/doneness, remove from oven. Using tongs, transfer meat to a large cutting board and cover with aluminum foil.
Let meat rest for 5-10 minutes.
Once rested, begin slicing meat (against the grain). The grain shifts directions in the middle of a tri tip, so shift the direction of your slicing as the grain changes.
Once sliced, add the ingredients for the Salty Herb Butter into the drippings in the pot - mix until combined. Drizzle the butter mixture from the pan over the meat or brush with a basting brush. Lastly, top generously with salt (flake sea salt is my favorite for finishing off meat, but you can use any kind you have).Enjoy!
