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 removing the tri-tip from the packaging and patting it dry with paper towels. This helps the seasoning stick better and promotes a good sear.
Next, season the meat generously with salt, pepper, and any other spices you enjoy, like garlic powder or smoked paprika. Let it sit at room temperature for about 30 minutes to allow the flavors to penetrate.
Preheat your oven to 425°F (220°C). While the oven is heating, heat a cast-iron skillet or oven-safe pan over medium-high heat.
Once the pan is hot, add a little oil and sear the tri-tip for about 3-4 minutes on each side until it develops a nice brown crust. This step adds flavor and texture.
After searing, transfer the pan to the preheated oven. Cook the tri-tip until it reaches an internal temperature of about 130°F (54°C) for medium-rare, which usually takes around 20-30 minutes, depending on the size.
Use a meat thermometer to check the temperature, as it’s the best way to ensure perfect doneness.
When it’s done, remove the tri-tip from the oven and let it rest for at least 10 minutes. Resting helps the juices redistribute, keeping the meat moist.
Finally, slice the tri-tip against the grain to ensure tenderness. Serve it with your favorite sides and enjoy!
