Buttery Steakhouse Tri-Tip Grilled Cheese
Buttery Steakhouse Tri-Tip Grilled Cheese
This is grilled cheese for grown-ups. Thinly sliced tri-tip, rubbed with Kinder’s Buttery Steakhouse Seasoning and grilled hot until the crust sets, layered onto sourdough with sharp cheddar, jammy caramelized onions, and sautéed red peppers, then buttered and griddled until the bread goes deep golden and the cheese pulls. That’s the sandwich.
Grilled cheese stops being a snack the moment tri-tip goes into it. One of the better second-day plays in the steak lineup.
Buttery Steakhouse Seasoning drives the flavor in this sandwich. It’s a rich, herb-forward blend built for beef, butter, garlic, thyme, rosemary, and when it hits a hot grill on tri-tip, it builds a crust that tastes like a proper steakhouse, not a condiment. Apply it generously, let the meat rest in the fridge for at least 30 minutes, pull it to room temp before grilling, and don’t rush the sear. The flavor is in the crust.
Tri-tip is the right cut here. It has the structure to slice thin against the grain without shredding, enough marbling to stay juicy inside a sandwich, and a beefy flavor that stands up to the richness of the cheddar and caramelized onions. Grill to 130–135°F for medium-rare. Rest it ten minutes before you slice.
Don’t sleep on the sourdough either. Its tang cuts against the richness of the beef and cheese. Its density holds up to the filling without going soggy. Don’t swap it for sandwich bread and expect the same result.
This recipe makes 4 sandwiches. Active time is about 35 minutes once the grill is hot, but plan for at least 30 minutes of refrigeration rest for the meat before you light the grill. Build that into your timeline and nothing is rushed.

Ingredients
Equipment
Method
- Season and Rest the Tri-Tip:
- Season the tri-tip generously on all sides with Kinder’s Buttery Steakhouse Seasoning. Wrap and refrigerate for at least 30 minutes.
- Remove the seasoned tri-tip from the refrigerator 30 minutes before grilling to allow it to come closer to room temperature.
- Grill the Tri-Tip:
- Preheat outdoor grill to high heat (450 degrees F). If using charcoal, arrange coals to create a direct and indirect heat zone.
- Sear tri-tip directly over high heat for 5-7 minutes per side until a deep, golden crust forms.
- Move to indirect heat and continue cooking until the internal temperature reaches 130-135 degrees F for medium-rare.
- Remove from the grill and rest for 10 minutes on a cutting board. Then slice thinly against the grain.
- Prepare Vegetables:
- Melt 1 Tbsp butter in a large skillet over medium-high heat. Add sliced onions and cook, stirring occasionally, for 15-20 minutes until deeply golden and caramelized.
- Add sliced red bell pepper and cook 5-8 minutes until softened. Remove from heat and allow to cool slightly.
- Build and Grill the Sandwich:
- Butter one side of each bread slice generously with the remaining 2 Tbsp butter.
- Place two bread slices butter-side down in the skillet over medium heat. Layer each with one slice of cheddar, then an even amount of sliced tri-tip and caramelized vegetables, then a second slice of cheddar. Top with the remaining bread slices, butter-side up.
- Cook until the bottom is deep golden brown, about 3-4 minutes. Flip carefully and cook the other side until golden and the cheese is fully melted.
- Slice each sandwich in half diagonally and serve immediately.

Notes
- Caramelize low and slow — 15–20 minutes over medium heat with occasional stirring. High heat browns the onions but skips the sweetness. Pull them when they’re deep golden and jammy.
- Double the cheese layer — one slice on the bottom of the filling, one on top. It melts from both sides and locks everything together.
- Medium heat on the griddle — high heat scorches the bread before the cheese melts. Medium lets both happen at the right pace.
- Rest the tri-tip fully — 10 full minutes on the cutting board after grilling. Cut it early and the juices end up on the board, not in the meat.
- Slice against the grain — find the direction the muscle fibers run and cut perpendicular to them. Thin slices against the grain keep the beef tender inside the sandwich.
- Sourdough holds — its structure and tang are built for a filling this generous. It’s not optional.
- A sharp green salad or arugula is the right call — the bitter edge cuts through the richness. Tomato soup turns it into a French dip situation if you add a small cup of au jus or beef broth for dipping.
- Dill pickles or pickled jalapeños alongside sharpen each bite and cut the fat cleanly. A cold, full-bodied beer holds up to the seasoning — a stout or amber ale works without competing with the beef.
- If you’re feeding a crowd, grill the tri-tip ahead and keep it on a rack while you griddle sandwiches to order.
- Assembled sandwiches are best eaten fresh off the skillet. The bread softens quickly — don’t hold them.
- Sliced tri-tip refrigerates well for up to 4 days in an airtight container. Use leftovers in tacos, on a salad, or reheat in a skillet over medium heat for another round of sandwiches. Skip the microwave — the texture suffers.
- Caramelized onions and peppers keep for 4 days refrigerated. The flavors deepen overnight, so the filling is actually better on day two.

Let us know how it was!Frequently Asked Questions
Can I make this without a grill?
Yes. Sear the tri-tip in a ripping-hot cast-iron skillet with a thin layer of oil, 4–5 minutes per side. Finish in a 400°F oven until the internal temperature hits 130–135°F. Rest and slice as directed.
Can I use a different cut of beef?
Flank steak or skirt steak both work. They slice thinner naturally and cook faster, so watch the temperature closely. Tri-tip’s structure makes it the best option for sandwich slicing.
What if I want it cooked past medium-rare?
Pull the tri-tip at 155–160°F for well-done. It’ll be firmer and less juicy. Go 140–145°F for medium, still tender, less pink.
Can I prep components ahead?
Yes. Grill the tri-tip and caramelize the vegetables up to a day in advance. Refrigerate separately. Pull the meat to room temp before slicing, then build and griddle the sandwiches fresh.
What’s the best cheese substitute?
Gruyère or provolone both melt well and stay cohesive. Gruyère adds a nutty depth that pairs with the herb-forward seasoning. Sharp cheddar is still the first choice for its bite and pull.
Can I scale this for a larger group?
One pound of tri-tip makes 4 sandwiches. For 6–8, add a second pound. Grill both at the same time and griddle sandwiches in batches while the meat rests.
