Taco seasoning (look for a good brand) makes these crispy fish tostadas a breeze to put together. If you’re lucky enough to find pre-made tostadas at your grocery store, dinner can be on the table in under 20 minutes.


  • 6 (6-inch) corn tortillas

  • 2 tablespoons neutral oil, plus more for brushing

  • 1 to 3 teaspoons taco seasoning, depending on heat preference

  • Salt and freshly ground pepper

  • 1 portion white fish such as Pacific cod, rockfish, lingcod, or halibut (10 to 12 ounces) cut into 1-inch pieces Available in Our Seafood Subscription Box

  • 1 ripe avocado, mashed

  • ¼ cup sour cream

  • 1 lime, cut into 4 wedges

  • Shredded lettuce, chopped tomatoes, sliced radish, sliced scallion, and chopped cilantro for serving


Make the Tostadas

Preheat the oven to 400°F with a rack in the center position. Brush a baking sheet with oil and arrange tortillas in a single layer. Brush tortillas generously with oil on both sides and place on the baking sheet. Top with another baking sheet (so the tortillas lay flat) and bake until golden brown and crisp, 15 to 16 minutes, flipping them once and checking occasionally to avoid burning.

Season the Fish

In a medium bowl, combine the taco seasoning, 2 tablespoons oil, and a pinch each salt and pepper. Pat the fish dry, then add to the mixture and toss to coat.

Make the Garnishes

In a small bowl, mash the avocado and season with salt and pepper. In another small bowl combine sour cream with the juice from 1 lime wedge and 2 tablespoons water.

Sauté the Fish

Heat a cast iron skillet over medium heat until hot. Add the fish, scraping any oil and seasonings into the skillet, and cook, turning once or twice until opaque and lightly charred, 4 to 5 minutes. Transfer to a bowl and squeeze 1 lime wedge over the fish.

Finish and Serve

Arrange the tostadas on plates and top with the avocado, followed by the fish and lime cream. Garnish with lettuce, tomato, radishes, scallions, and cilantro and serve.

Pro Tips

Pair it Up

Crisp and light, Pinot Grigio would be a pourable, enjoyable tipple here, as would a pilsner or lager if beer is what you’re looking for.

Level It Up

For homemade taco seasoning, use ½ teaspoon each ground cumin and chile powder and ¼ teaspoon each garlic powder, dried oregano, and cayenne pepper.

Change It Up

It’s doubtful that there’ll be leftovers, but if you build your own tostadas at the table and keep everything separate, you can toss everything together the next day for a killer taco salad.

Lighten It Up

Use reduced-fat sour cream or yogurt for the lime crema. You can also spray the tortillas with cooking spray for a lighter coating of oil.
