To cook Costco tri tip, season it well, sear it on high heat, and then roast it in the oven until it reaches your desired doneness.
Start by preheating your oven to 425°F (220°C).
While it heats, take the tri tip out of the packaging and pat it dry with paper towels.
Next, season the meat generously with salt, pepper, and any other spices you like. Garlic powder, onion powder, or a ready-made steak rub work great.
In a large, oven-safe skillet, heat a tablespoon of oil over medium-high heat.
Once the oil is hot, carefully place the tri tip in the skillet. Sear it for about 4-5 minutes on each side until you see a beautiful brown crust forming.
After searing, transfer the skillet to the preheated oven.
Cook the tri tip for about 20-30 minutes, depending on its size and your preferred level of doneness. Use a meat thermometer to check for doneness: 135°F (57°C) for medium-rare, 145°F (63°C) for medium.
Once done, remove the skillet from the oven and let the meat rest for about 10-15 minutes.
This resting period allows the juices to redistribute, ensuring a juicy and flavorful cut when you slice it.
Finally, slice against the grain and serve. Enjoy your perfectly cooked Costco tri tip!
