A tostada is a tortilla that’s fried until crisp, then topped with ingredients of any sort. You can purchase tortillas that are already made into tostadas, but homemade tastes much fresher. We use the oven rather than a skillet to make tostadas; this technique, which requires less oil and allows you to toast more than one at a time. For topping the tostadas, canned tuna combined with sweet corn, smoky chipotle, citrus juice and zest, and quick-pickled onion, plus a little mayonnaise as binder, is a refreshing take on tuna salad.

Ingredients
  • ½

    medium red onion, thinly sliced

  • 1

    teaspoon grated lemon OR lime zest, plus 2 tablespoons lemon OR lime juice

  • Kosher salt and ground black pepper

  • 4

    6-inch corn tortillas

  • 1

    tablespoon grapeseed or other neutral oil

  • 1

    5-ounce can albacore tuna in water, drained and flaked

  • 1

    tablespoon mayonnaise

  • 1

    tablespoon extra-virgin olive oil

  • ½

    cup frozen corn kernels, thawed and patted dry

  • 1

    chipotle chili in adobo, finely chopped

  • Roughly chopped fresh cilantro OR thinly sliced scallions, to serve

  • Optional garnish: Sliced avocado OR shredded lettuce OR pickled jalapeños OR sour cream OR a combination

Step 1

Heat the oven to 400°F with a rack in the upper-middle position. In a medium bowl, stir together the onion, lemon juice and ¼ teaspoon salt; set aside.

Step 2

Brush the tortillas on both sides with the neutral oil, then place them in a single layer on a rimmed baking sheet. Bake until golden brown and crisp, 8 to 10 minutes, flipping them once about halfway through. Let the tostadas cool on the baking sheet.

Step 3

To the pickled onion, add the tuna, mayonnaise, olive oil, corn, chipotle, lemon zest and ¼ teaspoon pepper; stir to combine. Taste and season with salt and pepper.

Step 4

Place the tostadas on individual plates. Top with the tuna mixture, dividing it evenly, then sprinkle with cilantro.
