Boom Boom Tri Tip Marinade Recipe

When I’m feeding a big group and want them to feel like they got steak night, this is the one I make. It was inspired by my hockey buddy Freddy, and it’s been my go-to for entertaining ever since. Individual steaks for a crowd get expensive fast. A tri tip in a four-ingredient marinade gets you the same steakhouse flavor for a fraction of the cost. It’s salty and savory from the soy and Worcestershire, with a peppery, garlicky crust from my Boom Boom Spice Blend.

This is my low and slow tri tip. It sits in the marinade, gets a long, gentle smoke at 180°F on the Traeger, finishes wrapped in foil, and then gets a hard sear at the end. The honest hard part is time. Between the marinade and the cook, this is an afternoon project, not a weeknight one. If you need tri tip on the table in two hours, I’ll point you to a faster method at the bottom.

Here’s what I’ll cover:

• The 4-ingredient tri tip marinade I’ve been making for years
• How long to marinate tri tip (and when it’s too long)
• How to smoke a marinated tri tip low and slow, then sear it
• The internal temps to watch so it doesn’t overcook
• My best tips and answers to the most common tri tip marinade questions

Let’s get started!

Why You Should Make This Tri Tip Marinade

• Four ingredients you already have: Soy sauce, Worcestershire, olive oil and a steak seasoning. No blender, no fresh herbs, no shopping trip.
• Big flavor on a lean cut: Tri tip is lean, so it doesn’t bring a lot of fat to the party. The soy and Worcestershire push savory, salty flavor into the meat, and the oil helps the seasoning stick and brown.
• Steak night for a crowd: One tri tip feeds four to five people for a lot less than a pack of sirloins or filets, and you’re only watching one piece of meat.
• Works on any cooker: I smoke it on the Traeger, but this marinade is just as good on a gas grill, a kettle, or under the broiler.

Ingredients for Tri Tip Marinade

Marinade

• 1/4 cup soy sauce: The base of the marinade. It brings salt and that deep, savory flavor. Low-sodium soy works fine if you’re watching salt, and tamari makes it gluten free.
• 2 tbsp Worcestershire sauce: Adds tang and a little sweetness that plays well with beef.
• 2 tbsp olive oil: Helps carry the seasoning onto the meat and keeps the outside from drying out during the long smoke.
• 2 tbsp Rock’s Boom Boom Spice Blend: My Montreal-style steak seasoning. It’s coarse black pepper and garlic with coriander and caraway, and it builds a great crust when it hits the sear. Don’t have it? Any Montreal steak seasoning works.

Meat

• 1 tri tip roast, 2-2 1/2 lbs: Look for one with even thickness and some marbling. If it has a thick fat cap or silver skin, trim it down before it goes in the marinade so the flavor can actually get into the meat.

Wood Pellets

• Traeger Signature Series pellets: A blend of hickory, maple and cherry. It’s balanced enough for a long smoke and doesn’t fight with the soy and Worcestershire. Oak or hickory also work if you want a bolder smoke.

How Long to Marinate Tri Tip

Short answer: 4 to 12 hours is the sweet spot. Even 15 minutes is better than nothing, so don’t skip the recipe if you’re short on time.

Marinate Time	What You Get
15-30 minutes	Flavor on the surface only. Still good, especially with the long smoke.
2-4 hours	Noticeable flavor in the outer layer of the meat.
4-12 hours (best)	Seasoned through, with a deep savory flavor and good texture
Overnight (up to 24 hours)	Max flavor. Saltier, so go with low-sodium soy if you plan this long.
Over 24 hours	Not worth it. The salt in the soy starts to make the outside texture soft and a little ham-like.

Keep it in the fridge the whole time and flip the bag once or twice so every side gets equal time in the marinade.

Equipment

• Traeger Timberline 1300 (or any pellet grill that holds 180°F and gets to 500°F)
• 1 gallon zip-top bag for marinating
• Aluminum foil for the wrap
• Instant-read or wireless meat thermometer
• Sharp slicing knife and a big cutting board

Step 1: Mix the Marinade (5 Minutes)

• Add the soy sauce, Worcestershire, olive oil and Rock’s Boom Boom Spice Blend to a 1 gallon zip-top bag.
• Seal it and squish it around until the seasoning is mixed into the liquid.

Step 2: Marinate the Tri Tip (15 Minutes to 24 Hours)

• Trim any thick fat cap and silver skin off the tri tip.
• Put the tri tip in the bag, push out as much air as you can, and seal it.
• Massage the marinade into the meat, then lay the bag flat in the fridge.
• Let it go 4 to 12 hours for the best flavor, flipping the bag once or twice.

Step 3: Fire Up the Traeger to 180°F (15 Minutes)

• Fill the hopper with Traeger Signature Series pellets (or oak or hickory).
• Set the Traeger to 180°F and preheat with the lid closed for about 15 minutes.
• If your grill has Super Smoke, turn it on. The low temp is where you get the most smoke flavor, and that’s the whole point of this first stage.

Step 4: Smoke Low at 180°F (About 3 Hours)

• Pull the tri tip out of the bag and let the extra marinade drip off. Toss the leftover marinade. It’s had raw meat in it.
• Place the tri tip right on the grill grate and insert your thermometer probe into the thickest part.
• Smoke at 180°F for about 3 hours. At this temp the meat climbs slowly, which gives it plenty of time to take on smoke without overcooking. Keep an eye on the probe. If it gets near 120°F before the 3 hours are up, move on to the next step.

Step 5: Wrap and Finish at 275°F (45-90 Minutes)

• Pull the tri tip and turn the Traeger up to 275°F.
• While the grill climbs, wrap the tri tip tightly in aluminum foil. The foil holds the moisture in and helps the marinade flavor soak in during the finish.
• Once the grill is at 275°F, put the wrapped tri tip back on.
• Cook until it reaches 130°F internal, usually 45 to 90 minutes depending on the size and where it ended up after the smoke.

Step 6: Sear at 500°F (6-8 Minutes)

• At 130°F, take the wrapped tri tip off and crank the Traeger to 500°F. Leave it wrapped while the grill heats so it stays warm.
• When the grill hits 500°F, unwrap the tri tip and put it right on the grate.
• Sear for 3-4 minutes per side until you have a dark crust. The sugars in the Worcestershire and soy brown up fast, so watch it.
• This method lands right around medium, about 135-140°F after the rest. If you like it closer to medium-rare, pull it out of the foil at 120-125°F instead.

Step 7: Rest and Slice (15 Minutes)

• Let the tri tip rest for 10 minutes on the cutting board. Resting keeps the juices in the meat instead of on your board, and tri tip is lean enough that you want every bit of it.
• Find where the grain changes direction. It’s usually near the middle of the tri tip. Cut it in half there.
• Slice each half against the grain into 1/4 inch slices, and ENJOY!

Tri Tip Marinade Key Steps

• Mix soy sauce, Worcestershire, olive oil and Rock’s Boom Boom Spice Blend in a zip-top bag.
• Trim the tri tip and marinate it in the fridge for 4-12 hours.
• Preheat the Traeger to 180°F with Super Smoke on.
• Smoke for about 3 hours.
• Wrap in foil and finish at 275°F to 130°F internal.
• Crank to 500°F and sear 3-4 minutes per side.
• Rest 10 minutes.
• Cut in half where the grain changes and slice each half against the grain.

This Is Where People Mess Up

• Marinating too long: More isn’t always better. Past 24 hours, the salt in the soy sauce starts to change the texture on the outside of the meat. Stick to 4 to 12 hours.
• Searing with marinade still dripping off: Excess marinade causes flare-ups and burns before you get a crust. Let it drip off before it goes on the smoker, and unwrap it before the sear.
• Reusing the marinade: Once raw meat has been in it, it’s done. If you want a sauce for the table, mix up a fresh small batch and simmer it for a few minutes.
• Slicing with the grain: Tri tip’s grain changes direction near the middle. One straight cut down the whole thing means half your slices go with the grain, and that’s where the chewiness comes from.

Variations

• No Traeger? Grill it over indirect heat around 250°F until it hits 120°F, then sear it over direct heat. Or roast it at 275°F in the oven and sear it in a ripping hot cast iron skillet.
• No Boom Boom? Any Montreal steak seasoning works, or use 1 tbsp coarse black pepper and 2 tsp garlic powder.
• Gluten free: Swap the soy sauce for tamari and check the label on your Worcestershire.
• A little sweeter: Add 1 tbsp brown sugar to the marinade. Watch the sear closely, because sugar burns fast at 500°F.

Common Questions

What is the best tri tip marinade?
The best tri tip marinade has salt, acid, fat and seasoning. Soy sauce brings the salt, Worcestershire brings the tang, olive oil helps the flavor stick, and a coarse steak seasoning gives you a crust. That’s exactly what this four-ingredient marinade does.

How long should you marinate tri tip?
Plan on 4 to 12 hours in the fridge for the best flavor. Even 15 minutes helps. I wouldn’t go past 24 hours with a soy-based marinade, because the salt starts to change the texture.

Should you marinate tri tip or use a dry rub?
Both work. A marinade pushes savory flavor into a lean cut and gives you a little insurance against drying out on a longer cook. A dry rub gives you a better bark and is faster. This recipe uses a marinade. If you’d rather go with a dry rub and a quick reverse sear, I’ve got a separate smoked tri tip recipe for that.

Does tri tip need to be marinated?
No. A good tri tip is plenty flavorful with just salt, pepper and garlic. A marinade is a great way to add more savory flavor, especially if you’re cooking it low and slow for a few hours like this recipe.

Can you marinate tri tip overnight?
Yes. Overnight is fine with this marinade. If you know you’re going overnight, use low-sodium soy sauce so it doesn’t end up too salty.

What temperature is tri tip done?
Pull it at 130°F before the sear for medium, or 120-125°F for medium-rare. Tri tip is lean, so I wouldn’t take it much past 145°F or it starts to get chewy.

Why wrap tri tip in foil?
After 3 hours of smoke, the foil holds in moisture and lets the tri tip finish cooking gently without drying out. It also keeps the outside from getting too dark before the final sear.

How do you make tri tip tender?
Three things: don’t overcook it, let it rest for 10 minutes, and slice it against the grain. Remember that the grain changes direction partway through, so cut the tri tip in half first.

Can I use this tri tip marinade on the grill?
Absolutely. It’s a great grilled tri tip marinade. Cook it over indirect heat until it hits about 120°F, then finish it over direct high heat to sear.

Final Thoughts

This tri tip marinade has been in my rotation for years because it’s simple and it works. Four ingredients go in a bag, a few hours of smoke go on the Traeger, and you end up with savory, tender tri tip that feeds a crowd for less than a pack of steaks. Give yourself the afternoon, watch your temps, and remember to cut it in half before you slice.
