Marinated Tri-Tip Nachos
Marinated Tri-Tip Nachos
Nachos loaded with grilled, beer-marinated tri-tip hit different than anything built on pre-cooked beef or rotisserie chicken. This version starts the night before. The tri-tip soaks in a soy, beer, garlic, and black pepper marinade that works into the grain, seasoning the meat from the inside out. You sear it over high heat to build crust, move it to indirect heat to finish, and pull it at 130–135°F internal. Rest it ten full minutes before you touch it. Slice thin against the grain, chop into bite-sized pieces, then layer it generously over sharp cheddar and tortilla chips. Eight minutes at 400°F and the cheese is melted and bubbling. Fire-roasted corn, diced tomato, jalapeño, cilantro, and guacamole go on the moment it comes out of the oven.
Starts the night before, which is the trade plenty of our grilling recipes ask for.
Tri-tip is a well-marbled bottom sirloin cut that most beef sections carry. It grills fast, slices clean, and carries bold marinade flavors without disappearing under layers of cheese and toppings. The beer in the marinade adds a malty undertone and helps break down the surface. Soy handles the salt and umami base. Garlic salt and black pepper round it out, simple, but the overnight rest is where the marinade does real work.
Plan around the marinade time and the rest of the cook is straightforward. Hot grill, meat thermometer, sheet pan. The tri-tip doesn’t need much else. The result is a nacho plate built around char-edged, medium-rare beef, not just something scattered over chips as an afterthought, but the whole reason the dish works.

Ingredients
Equipment
Method
- MARINADE — In a bowl, combine garlic salt, ground black pepper, soy sauce, and beer to create the marinade.
- Place the tri-tip roast in a large resealable plastic bag.
- Pour the marinade over the tri-tip, ensuring it is well coated.
- Seal the bag, massaging gently to distribute the marinade evenly throughout the meat.
- Refrigerate for at least 2 hours (overnight is ideal for maximum flavor).
- Remove the tri-tip from the refrigerator 30 minutes before grilling to bring it closer to room temperature.
- GRILLING — Preheat the grill to high heat (approximately 450°F).
- Place the tri-tip directly on the grill grates.
- Grill for 5-7 minutes on the first side without moving, developing a nice crust.
- Flip the tri-tip and grill the second side for approximately 8 minutes.
- Move the tri-tip to indirect heat (unlit side of grill or cooler zone).
- Continue cooking until the internal temperature reaches 130-135°F for medium-rare, checking with a meat thermometer.
- Remove from grill and let rest on a cutting board for at least 10 minutes — this is crucial for retaining juices.
- Slice the tri-tip thinly against the grain, then chop into bite-sized pieces for nachos.
- NACHOS — Preheat oven to 400°F.
- Line a baking sheet with aluminum foil.
- Spread half of the tortilla chips in a single layer on the prepared baking sheet.
- Sprinkle half of the shredded sharp cheddar cheese over the chips.
- Layer the chopped tri-tip meat generously on top.
- Repeat layers with remaining chips and cheese.
- Bake at 400°F for 8-10 minutes until cheese is completely melted and bubbling.
- Remove from oven and immediately top with fire roasted corn, diced tomatoes, sliced jalapeños, fresh cilantro, and spoonfuls of guacamole.
- Serve immediately with lime wedges on the side.
Nutrition
Notes
- Marinade overnight — Two hours is the minimum, but overnight is where the beer-and-soy fully penetrates the grain. The difference in depth is noticeable.
- Bring the meat up before grilling — Pull the tri-tip from the fridge 30 minutes before it hits the grates. Cold meat cooks unevenly and leaves a gray band under the crust.
- Use a thermometer, not a timer — Tri-tip varies in thickness across the cut. Pull at 130–135°F for medium-rare. The timer is a rough guide; the thermometer is the answer.
- Slice against the grain — The tri-tip’s grain runs in two directions where the two muscles meet. Find the grain before you slice. Cutting with it gives chewy strips; cutting against it gives tender bites.
- Layer the nachos, don’t pile them — Spread one layer of chips and cheese, add the tri-tip, then a second layer of chips and cheese. Piling everything at once leads to a soggy center. Layering means every chip has coverage.
- Add cold toppings after the oven, not before — Guacamole, fresh tomato, cilantro, and jalapeño go on after the sheet pan comes out. Cool and fresh against hot cheese and char is the contrast that makes the dish.
- Serve directly off the sheet pan — nachos lose their crunch fast, so don’t plate and then wait. Have the guacamole, lime wedges, and hot sauce already out so everything goes on in one motion right at the table.
- Cold beer is the right pairing. A lager or a light Mexican-style beer cuts through the richness of the cheddar and the fat in the tri-tip. A margarita on the rocks works equally well — the lime in the drink mirrors the lime on the plate.
- If you’re feeding a crowd, double the chips and cheese but keep the tri-tip quantity the same. The beef is the point of this dish. Spreading it thin across twice the chips dilutes what makes it work.
- Pickled red onions or sliced radishes add a sharper acidic hit than fresh tomato alone. A thin drizzle of crema over the top adds richness without overpowering the beef underneath.
- Assembled nachos don’t store. Once baked, the chips absorb moisture from the cheese and toppings within the hour — there’s no recovering that texture. Build what you’ll eat.
- The cooked tri-tip is different. Refrigerate leftover sliced beef in an airtight container for up to three days. It reheats quickly in a hot skillet — which brings some of the crust back — or works cold in sandwiches, grain bowls, or tacos the next day.
- Uncooked, marinated tri-tip can stay in the bag in the refrigerator for up to 24 hours if you’re planning ahead. Beyond that, the soy and acid begin to break down the surface texture.

Let us know how it was!Frequently Asked Questions
Can I make marinated tri-tip nachos without a grill?
Yes. Sear the tri-tip in a cast iron skillet over high heat, then finish in the oven at 375°F until it hits 130–135°F internal. The char won’t be identical to a grill, but you’ll still get a solid crust and the marinade flavors carry through.
What beer works best for tri-tip marinade?
Any cold lager keeps the flavor clean and lets the soy and garlic come forward. A darker beer, amber, stout, adds more malt character. Avoid anything too hoppy or too sweet, which can turn bitter during the marinade.
How do you slice tri-tip for nachos?
Slice thin against the grain first, then chop the slices into roughly half-inch pieces. Tri-tip has two grain directions where the two muscles meet, find the seam and adjust your angle as you cross it. Small, even pieces stay on the chips better than large slabs.
How long should tri-tip marinate?
Two hours minimum. Overnight gives you more depth. The marinade base, beer and soy, is mild enough that it needs time to work through the grain. Don’t shortcut this step.
Can I prep the tri-tip a day ahead?
Yes. Grill, rest, and slice the tri-tip up to a day ahead. Store covered in the fridge and bring it close to room temp before assembling the nachos. Bake the chips and cheese fresh, don’t assemble and refrigerate.
What internal temperature should tri-tip reach for nachos?
Pull it at 130–135°F on the grill for medium-rare. The beef gets layered and baked again at 400°F for 8–10 minutes, which carries it a bit further, medium-rare off the grill finishes closer to medium by the time the nachos come out of the oven.
