Equipment

Ingredients

For the Carne Asada:

  • 2 pounds flap meat or skirt steak
  • 1 tbsp soy sauce
  • 1 tbsp fresh lime juice
  • 1 tsp garlic powder
  • 1 tsp cumin
  • 1 tsp smoked paprika
  • ½ tsp black pepper
  • 1 tbsp neutral oil
  • Salt to taste

For the Charred Jalapeño Crema:

  • ½ cup Mexican crema
  • 1 ripe avocado
  • 2 tbsp mayo
  • 1 –2 jalapeños charred and seeded
  • 1 small garlic clove
  • ¼ cup fresh cilantro
  • 1 tbsp fresh lime juice
  • Salt to taste

For the Guacamole:

  • 3 ripe avocados
  • 2 tbsp fresh lime juice
  • Salt to taste

For Assembly:

  • 4 –6 store-bought tostadas
  • Pico de gallo store-bought or homemade
  • Finely ground cotija cheese

Instructions

  • Toss the steak with soy sauce, lime juice, garlic powder, cumin, smoked paprika, black pepper, and oil. Let marinate while you prep everything else.
  • For the crema, scoop out a quarter of the avocado and add it to a blender along with the crema, mayo, charred jalapeños, garlic, cilantro, and lime juice. Blend until completely smooth and vivid green. Taste and adjust salt as needed. Refrigerate until ready to use. Dice the remaining three quarters of that avocado and set aside to fold into the guacamole.
  • Mash the 3 guacamole avocados with the diced reserved avocado, lime juice, and salt until creamy but still slightly chunky. Set aside.
  • Heat a grill or cast iron skillet over screaming-high heat. Sear the steak 4–5 minutes per side until deeply charred and caramelized on the outside and cooked to your desired doneness.
  • Let rest 5 minutes, then cut into small bite-sized pieces against the grain and season with a pinch of flaky sea salt immediately after cutting.
  • To assemble, spread a generous layer of guacamole across each tostada all the way to the edges. Pile the steak generously over the guacamole, drizzle the jalapeño crema over everything, and spoon the pico de gallo over the top. Finish with a generous dusting of ground cotija and serve immediately.

Notes

  • Let the steak rest the full 5 minutes before cutting. Slicing too early means all that juice ends up on the cutting board instead of in each bite.
  • Season the steak with flaky sea salt right after cutting, not before. Salting hot, freshly sliced meat lets the salt stick and melt into the surface for better flavor.
  • Spread the guacamole all the way to the edges of the tostada so every bite has a creamy base under the steak.
  • Char the jalapeños until fully blistered, the smokiness is what gives the crema its depth, so don't pull them off too early.
  • For a party-ready appetizer, assemble these on mini tostadas or sturdy tortilla chips and arrange on a platter. Same layers, smaller bites and perfect for passing around.
