  • Please select only one of the 3 following cooking methods for the tri tip. I prefer the super tender sous vide option!
  • Super Tender Costco Tri-Tip Roast (Sous Vide)

  • Grill
    Preheat grill to medium heat (350°F) for two-zone grilling. 
    Combine garlic powder, salt, and pepper and apply all over the tri-tip. 
    Create mopping liquid with 1/4 Cup olive oil, 1/4 cup red wine, 2 tablespoons of red wine vinegar, and optional 4 cloves of garlic. 
    Place tri-tip over indirect hit and flip every 6-7 minutes while mopping with liquid.
    Continue until the internal temperature reaches 120°F. 
    Once 120°F internal temperature is reached, place the tri-tip over direct heat and grill until desired internal temperature. (135°F for medium rare)

    Rub Costco Tri-Tip with salt, pepper, and garlic powder.
    Place in roasting pan.

    Reduce oven temperature to 350°F and roast for another 10 minutes until internal temperature reaches 125°F.
    (Medium Rare).Rest for 10 minutes and slice against the grain.
