Instructions

Marinate the Steak

  • Whisk together all marinade ingredients until combined.
  • Lightly score the flank steak.
  • Place steak in a bag or dish and pour marinade over it.
  • Marinate for 2–6 hours max.

Cook the Steak

  • Preheat grill or skillet to high heat.
  • Cook steak 4–6 minutes per side depending on thickness.
  • Rest for 5–10 minutes, then slice thinly against the grain.

Roast Mushrooms & Onions

  • Preheat oven to 425°F.
  • Toss mushrooms, onions, garlic, olive oil, salt, and pepper.
  • Roast for 15–20 minutes until golden and slightly crisp.

Make Avocado Crema

  • Add all ingredients to a blender or food processor.
  • Blend until smooth and creamy. Set aside.

Assemble Nachos

  • Spread tortilla chips on a baking sheet.
  • Layer with cheeses, steak slices, and roasted vegetables.
  • Bake at 400°F for 8–10 minutes until cheese is melted.

Finish & Serve

  • Top with green onions, tomatoes, herbs, and optional toppings.
  • Drizzle generously with avocado crema.
  • Serve immediately.

Notes

  • Don’t over-marinate the steak—pineapple enzymes can break it down too much.
  • Slice steak very thin for the best bite on nachos.
  • Layer chips and toppings in two levels to avoid soggy nachos.
  • Use a sturdy chip to hold up to the steak and toppings.
  • Broil for the last 1–2 minutes for extra bubbly cheese.
