Things You'll Need

  • 1-1/2 pound beef tri-tip, trimmed

  • 1 teaspoon garlic powder

  • 1 teaspoon onion powder

  • 1 teaspoon mustard powder

  • 1/2 teaspoon dried oregano

  • 1/2 teaspoon dried thyme

  • 1 teaspoon sea salt

Step 1: Prepare the Tri-Tip

Stir together the garlic powder, onion powder, mustard powder, dried oregano, thyme, and salt in a small bowl to combine. Place the tri-tip on a cutting board and sprinkle with the seasoning. Gently rub seasoning into the tri-tip.

You can use any store-bought or homemade dry rub or marinade of choice.

Transfer tri-tip to a sealable bag or container and refrigerate for at least 1 hour. (When possible, up to 8 hours is best.)

Step 2: Get Ready to Bake

Remove the bag of tri-tip from the refrigerator and allow it to come to room temperature. This ensures the meat will cook evenly. Preheat the oven to 450 degrees Fahrenheit.

Pour enough wine, broth or beer into the bottom of a roasting pan, to cover the surface, about 2/3 to 1 cup. Place the meat in the roasting pan.

Step 3: Roast the Meat

Place roasting pan on the center rack of the preheated oven for 20 minutes. Reduce the heat to 350 degrees Fahrenheit and bake for another 20 to 40 minutes (20 minutes for rare tri-tip; 25 to 30 for medium-rare; and 35 to 40 for well-done). Note: Bake times will vary depending on thickness of meat.

For rare tri-tip, the internal temperature should be 120 degrees Fahrenheit. For medium-rare, the internal temperature should be 130 degrees Fahrenheit, and for medium, the internal temperature should be 140 degrees Fahrenheit. To check the internal temperature, poke a meat thermometer into the center of the thickest part of the tri-tip and let it sit until the needle stops moving.

Step 4: Allow Meat to Rest

Remove meat from the oven and transfer it to a plate or cutting board. Allow it to rest 10 minutes. This process ensures that the juices will distribute throughout the meat, making the meat more tender and juicy throughout. The internal temperature of the meat will raise about 6 to 10 degrees as it sits, so bare this in mind when choosing your bake time.

Step 5: Slice and Serve

Using a sharp knife, slice the tri-tip into thin slices (1/8 to 1/4-inch thick).
