How to Make Korean-Inspired Tri-Tip — Big Poppa's Smoked and Seared Method
Tri-tip is a California cut — underappreciated everywhere else, legendary on the West Coast. Big Poppa takes it Korean-inspired with a We Rub You Korean BBQ marinade soak, a Double Secret Steak Rub finish, and a two-phase cook that most people skip on tri-tip: smoke first at 275°F to 128°F, then a direct sear to 140°F. That final temperature is the key — tri-tip cooked to 128°F is still tough and chewy. The muscle needs to reach 140°F where it's still pink but the connective tissue has rendered enough to give you tender, sliceable meat. Garnish with crushed peanuts and chives and serve immediately.
The Critical Tri-Tip Temperature Mistake Most People Make
Most people who are unfamiliar with tri-tip cook it to 128°F and wonder why it's tough. Big Poppa's explanation is direct: at 128°F, tri-tip's muscle structure hasn't rendered enough to be tender. The fibers are technically medium-rare by temperature, but the cut needs more heat to break down the connective tissue that runs through it. At 140°F it's still very pink — the color of medium — but the texture is completely different. Tender, sliceable, juicy. That's the target.
The two-phase cook delivers exactly that: smoke at 275°F gives the marinade and Double Secret time to interact with the surface and build complexity, while the direct sear at the end creates the crust and drives the internal temp to that 140°F sweet spot. Don't skip the sear thinking the smoker temperature will get you there — you need the direct flame contact for the final push.
Why does the Korean marinade go on before the Double Secret rub?
The marinade soaks into the meat during the 30-minute to 4-hour window — the soy, sesame, and Korean spice flavors penetrate the muscle fibers. When you pull from the marinade, the Double Secret goes on top as the surface seasoning. The rub creates the outer crust while the marinade's flavor lives inside the meat. It's the same layering principle as Cash Cow plus a rub on a steak — each element has its own zone to work in.
Full Recipe: Korean-Inspired Tri-Tip
Ingredients:
- 1 tri-tip roast
- 1 bottle We Rub You Korean BBQ Marinade
- 3–6 tbsp Big Poppa Smokers Double Secret Steak Rub
- 1/2 cup peanuts, crushed (for garnish)
- 1–3 tbsp chives, chopped (for garnish)
- Preheat smoker to 275°F. Optional: set up a second grill for high-heat direct searing.
- Marinate the tri-tip. Place in We Rub You Korean BBQ Marinade while smoker preheats. Marinate for at least 30 minutes, up to 4 hours.
- Apply Double Secret. Pull tri-tip from marinade and season liberally with Double Secret Steak Rub. Let sit approximately 10 minutes until the rub melts into the surface.
- Smoke to 128°F. Place on smoker at 275°F. Cook until internal temperature hits 128°F — approximately 15–20 minutes per side. Pull from smoker and set aside.
- Increase heat and sear. Move to a high-heat direct grill. Sear approximately 5 minutes per side until internal temperature reaches 140°F.
- Rest 5–10 minutes. Allow to rest before slicing.
- Slice against the grain. Identify the changing grain direction and slice perpendicular to it. Garnish with crushed peanuts and chopped chives. Serve immediately.
Frequently Asked Questions: Korean-Inspired Tri-Tip
Pull from the smoker at 128°F, then sear to a final internal temperature of 140°F. At 128°F tri-tip is tough and chewy — the muscle structure needs the additional rendering that happens between 128°F and 140°F. At 140°F it's still very pink but noticeably tender. Don't stop at 128°F thinking you're at medium-rare done; the sear drives the final temperature.
At least 30 minutes, up to 4 hours while the smoker preheats. After marinating, pull the tri-tip, apply Double Secret Steak Rub, and let the rub rest on the surface for about 10 minutes before the smoker. The marinade seasons from the inside; the rub builds the outer crust.
Smoke at 275°F to 128°F internal — about 15–20 minutes per side. Pull and move to a high-heat direct grill. Sear about 5 minutes per side to 140°F. Rest 5–10 minutes. The smoke phase builds flavor and starts the cook evenly; the sear creates the crust and drives the final temperature.
Tri-tip has a grain that changes direction across the cut — identify both directions before you start. Slice perpendicular to the grain in each section, adjusting your angle as the grain shifts. Slicing against the grain is what separates a tender slice from a chewy one on tri-tip regardless of how well you cooked it.
Crushed peanuts and chopped chives finish this version — the peanuts add crunch and nuttiness that pairs with the Korean marinade's sesame notes, and the chives add fresh brightness. For a simpler version skip the marinade and garnishes and run it with just Double Secret — that's a classic California tri-tip preparation that stands completely on its own.

Main Dish
Big Poppa's Korean-inspired twist on California's favorite cut. Marinated in We Rub You Korean BBQ Marinade and finished with Double Secret Steak Rub, then cooked in two phases: smoke at 275°F to 128°F internal, followed by a direct sear to 140°F. The critical tip most people miss: tri-tip at 128°F is tough and chewy — the muscle structure needs the rendering that happens between 128°F and 140°F. At 140°F it's still very pink but genuinely tender. Garnished with crushed peanuts and chives. Works in sandwiches, tacos, and salads the next day.
Ingredients
1 tri-tip roast
1 bottle We Rub You Korean BBQ Marinade
1/2 cup peanuts, crushed (garnish)
1–3 tbsp chives, chopped (garnish)
Directions
Preheat smoker to 275°F. Optional: set up a second grill for high-heat direct searing.
Place tri-tip in We Rub You Korean BBQ Marinade while smoker preheats. Marinate at least 30 minutes, up to 4 hours.
Pull tri-tip from marinade and season liberally with Double Secret Steak Rub. Let the rub melt into the surface for approximately 10 minutes.
Place on smoker at 275°F. Cook until internal temperature reaches 128°F — approximately 15–20 minutes per side.
Increase heat and move to a high-heat direct grill. Sear approximately 5 minutes per side until internal temperature hits 140°F.
Rest 5–10 minutes.
Identify the changing grain direction across the tri-tip and slice against it, adjusting your knife angle as the grain shifts. Garnish with crushed peanuts and chopped chives. Serve immediately.
