Mexican Tostadas de Carne Asada are crispy, flavorful tostadas topped with juicy marinated steak, creamy guacamole, and fresh toppings, delivering a perfect balance of texture and authentic Mexican flavor.

Ingredients

2 lbs flank steak or skirt steak

1/4 cup olive oil

1/4 cup lime juice (about 23 limes)

4 cloves garlic, minced

1 teaspoon ground cumin

1 teaspoon smoked paprika

Salt and pepper, to taste

Fresh cilantro (for garnish)

810 corn tostada shells

2 cups guacamole (store-bought or homemade)

1 cup sour cream or Mexican crema

1 cup diced tomatoes

1/2 cup chopped fresh cilantro

Sliced jalapeños (optional for spice)

Lime wedges (for serving)

Instructions

  1. In a large bowl, whisk together olive oil, lime juice, minced garlic, cumin, smoked paprika, salt, and pepper.
  2. Add the flank or skirt steak to the marinade, turning it to coat evenly. Cover and refrigerate for at least 1 hour, preferably 4–6 hours for deeper flavor.
  3. Preheat a grill or grill pan over medium-high heat. Remove the steak from the marinade and pat dry.
  4. Grill the steak for 4–6 minutes per side, depending on thickness and desired doneness.
  5. Remove the steak from the grill, cover loosely with foil, and let it rest for 10 minutes before slicing thinly against the grain.
  6. Spread guacamole over each corn tostada shell.
  7. Top with sliced carne asada, a dollop of sour cream or crema, diced tomatoes, and chopped cilantro.
  8. Add sliced jalapeños if desired and serve with lime wedges on the side.
  9. Serve immediately to keep the tostada shells crisp.

Notes

Marinate the steak for up to 24 hours for maximum flavor.

Assemble tostadas right before serving to prevent sogginess.

For a dairy-free version, use a plant-based crema alternative.

Store leftover steak separately and reheat gently before assembling fresh tostadas.
