Marinated Pellet Grilled Tri-Tip Steak

If you haven’t made tri-tip on the pellet grill yet, buddy, you’re missing out. It’s tender, flavorful, and when you hit it with a killer marinade like the one I’m sharing below — and then give it a slow, smoky ride on the grill.

Equipment

  • Pellet Grill

Ingredients
  

  • 1 bottle Soy Sauce
  • 3/4 cup brown sugar
  • 4 cloves garlic
  • 1/2 onion diced Optional

Instructions
 

  • How to Marinate:
    Mix all ingredients in a bowl or zip-top bag. Drop in your tri-tip (usually 2–3 lbs), and make sure it’s fully coated. Seal it up and marinate overnight in the fridge — 12 to 24 hours is perfect. Flip it halfway through if you can.

  • 🔥 Pellet Grill Time & Temps
    Set your pellet grill to 225°F for that slow and steady smoke. I use hickory or oak pellets, but mesquite works great too if you want bolder flavor.

  • Internal Temps for Tri-Tip Doneness:
    Use a good meat thermometer (I’ve linked my go-to below) and pull your tri-tip off the grill at these temps:
    Rare: 120–125°F (cool red center)
    Medium Rare: 130–135°F (warm red center) — my personal favorite
    Medium Well: 145–150°F (slightly pink center)
    Well Done: 155°F+ (fully cooked, little to no pink)
    Once it hits your desired temp, sear it over high heat for 1–2 minutes per side if you want that perfect crust. Then let it rest, tented with foil, for about 10 minutes before slicing against the grain.
