“Fish Friday”: Closing Out the Lenten Season With a Bit of Spice

With Good Friday approaching, we’re closing out our “Fish Friday” recipe series with a spicy bang. This authentic fish taco recipe is the perfect blend of light and satisfying, featuring refreshing lime and herb notes paired with a burst of Mexican chili flavor. 

This week’s “Fish Friday” spotlight circles back to Frostmark’s premium wild-caught haddock fillets—lean and flaky with a hint of sweetness—perfectly balancing the refreshing and spicy elements of the most irresistible fish taco you’ve ever tasted. 


Made with Midnight Sun Wild Caught Pacific Cod loins

  • 1 lb Frostmark Wild Caught Haddock Fillets (thawed and patted dry) 
  • 2 tbsp olive oil 
  • 1 tsp chili powder 
  • 1/2 tsp smoked paprika 
  • 1/2 tsp cumin 
  • 1/2 tsp garlic powder 
  • Salt and black pepper 
  • Zest and juice of 1 lime  
  • 1/2 cup sour cream (or Mexican crema) 
  • 1–2 tsp chili powder (or chipotle powder for smokiness) 
  • 1 tsp lime juice 
  • 1 small clove garlic, finely grated 
  • Salt to taste  
  • Corn or flour tortillas 
  • Extra lime wedges 
  • 1. Prepare the haddock 
    Because Frostmark haddock is typically frozen, make sure it’s fully thawed in the fridge and patted very dry—this helps it grill properly instead of steaming.
    In a bowl, mix olive oil, spices, lime zest, lime juice, salt, and pepper.
    Coat the haddock evenly and let it sit for 10–15 minutes.  
  • 2. Make the slaw
    In a large bowl, combine cabbage, carrots, jalapeño, radish, and cilantro.
    Toss with lime juice, olive oil, and a pinch of salt.
    Let it sit while you cook the fish so it softens slightly and flavors meld. 
  • 3. Make the chily cream 
    Whisk together sour cream, chili powder, lime juice, garlic, and salt. 
    Adjust spice level to taste. Chill until ready to use. 
  • 4. Grill the haddock 
    Preheat grill (or grill pan) to medium-high and lightly oil it. 
    Place haddock on the grill and cook: 
    About 3–4 minutes per side 
    Until opaque and easily flaked 
    Tip: Haddock is delicate, so flip carefully or use a grill basket if needed. 
    Once cooked, break into large chunks.
  • 4. Warm tortillas 
    Lightly toast tortillas on the grill or in a dry pan until warm and pliable.
  • 5. Assemble tacos
    Layer each tortilla with: 
    Grilled haddock 
    Cilantro lime slaw 
    Drizzle of chili cream 
    Finish with a squeeze of fresh lime. 

Add sliced avocado for creaminess
Sprinkle cotija cheese for a salty finish
Swap chili powder for chipotle in adobo for deeper smoky heat 

These fillets are lean and mild, so the marinade and chili cream add needed richness and flavor.
If the fillets are thin, reduce cook time slightly to avoid overcooking.
If they seem fragile, you can grill them on foil for easier handling.
