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.

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.
