A fried fish sandwich made right in your kitchen in 30 minutes or less? Sign. Us. Up. For this winning rendition on a sumptuously savory sammie, mild, flaky tilapia fillets are dipped in Cajun-spiced tempura batter, then fried until golden and light-as-air crispy. They’re tucked cozily into toasted baguettes along with a swipe of tangy lime-spiked mayo and a tangle of crunchy cabbage slaw. On the side are golden Cajun-spiced potato wedges—the perfect match.

Produced in a facility that processes eggs, milk, fish, peanuts, sesame, shellfish, soy, tree nuts, and wheat.

Cooking Steps

Prep
1
  • Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce.

  • Cut potatoes into ½-inch-thick wedges. Zest and halve lime.

Season & Roast Potatoes
2
  • Toss potatoes on a foil-lined baking sheet with a large drizzle of oil, half the Cajun Spice Blend (you’ll use the rest in Step 4), salt, and pepper.

  • Roast on top rack until browned and tender, 20-25 minutes.

Make Slaw & Lime Mayo
3
  • Meanwhile, in a medium bowl, combine coleslaw mix, 1 tsp sugar (2 tsp for 4 servings), juice from half the lime, salt, and pepper.

  • In a small bowl, combine mayonnaise and as much lime zest as you like.

  • Refrigerate slaw and lime mayo until ready to use in Step 7.

Mix Batter & Coat Fish
4
  • In a large bowl, whisk together tempura batter mix, remaining Cajun Spice Blend, ½ cup cold water, and ½ tsp salt until smooth (⅔ cup water and 1 tsp salt for 4 servings). TIP: If mixture is too thick, add more cold water 1 TBSP at a time until it reaches a pancake-batter-like consistency.

  • Pat tilapia* dry with paper towels. Season all over with salt and pepper. Add tilapia to bowl with batter; gently turn until evenly coated.

Fry Fish
5
  • Heat a ¼-inch layer of oil in a large, heavy-bottomed pan over medium-high heat. Once oil is hot enough that a drop of batter sizzles when added to the pan, add tilapia in a single layer. (Shake off excess batter before adding.)

  • Cook until golden brown and cooked through, 2-3 minutes per side. (For 4 servings, fry fish in batches, adding more oil as needed and allowing oil to get hot in between batches) TIP: To check for doneness, cut one fillet in half.

  • Using tongs or a slotted spoon, transfer to a paper-towel-lined plate. Immediately season with salt and pepper.

Toast Baguettes
6
  • While tilapia cooks, halve baguettes lengthwise and toast until golden.

Finish & Serve
7
  • Spread cut sides of baguette halves with as much lime mayo as you like; fill with tilapia and slaw.

  • Divide sandwiches between plates; serve with potato wedges and any remaining lime mayo on the side for dipping.
