Ingredients

Scale
  • 1 lb (450 g) lean ground beef (90% lean preferred)
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 tsp ground cumin
  • 1 tsp smoked paprika
  • ½ tsp chili powder
  • Salt and pepper, to taste
  • 1 tbsp vegetable oil or olive oil
  • 1 medium red onion, thinly sliced
  • ½ cup (120 ml) apple cider vinegar
  • 1 tbsp sugar
  • 1 tsp salt
  • ½ tsp dried oregano (optional)
  • 1 small jalapeño, sliced (optional)
  • 68 corn tostadas
  • 1 cup shredded lettuce
  • 1 cup shredded cheddar or Mexican blend cheese
  • Fresh cilantro leaves, roughly chopped
  • Fresh lime wedges
  • Sour cream or Mexican crema (optional)

Instructions

  1. In a medium bowl, combine ½ cup apple cider vinegar, 1 tbsp sugar, 1 tsp salt, and ½ tsp dried oregano. Stir until sugar and salt dissolve. Add thinly sliced red onions and jalapeño slices, pressing them down to submerge. Set aside to marinate for at least 15 minutes.
  2. Heat 1 tbsp oil in a large skillet over medium-high heat. Add chopped onion and sauté for about 3 minutes until softened.
  3. Add minced garlic and cook for 30 seconds until fragrant.
  4. Add ground beef, breaking it apart with a spatula. Cook for 6-8 minutes until browned and no longer pink. Drain excess fat if necessary.
  5. Sprinkle in cumin, smoked paprika, chili powder, salt, and pepper. Stir well and cook for another 2 minutes to meld flavors.
  6. Warm store-bought tostadas in a 350°F oven for 5 minutes or fry corn tortillas in hot oil for about 1 minute per side until golden and crisp, then drain on paper towels.
  7. Assemble tostadas by layering seasoned ground beef, shredded lettuce, shredded cheese, and pickled onion slices with jalapeños.
  8. Garnish with fresh cilantro and a squeeze of lime juice. Add sour cream or Mexican crema if desired.
  9. Serve immediately for best crunch and flavor.

Notes

For best flavor, marinate pickled onions at least 15 minutes or overnight. Avoid overcrowding the pan when browning beef to ensure proper browning. Drain excess fat to keep tostadas crisp. Assemble just before serving to prevent sogginess. Use a non-metal bowl for pickling to avoid metallic taste.
