Instructions

  1. Prepare the Vegetables

    Thinly slice the purple and green cabbage, red onion, jalapeño, and chop the cilantro. Dice half of the avocado into bite‑size pieces and set aside the other half for mashing.

    Time: PT10M

  2. Make the Creamy Avocado Sauce

    In a large bowl combine mayonnaise, sour cream, the mashed half‑avocado, lime juice, paprika, cumin, salt and pepper. Mash with a fork until smooth.

    Time: PT5M

  3. Combine Slaw and Sauce

    Add the sliced cabbages, red onion, jalapeño, cilantro, and diced avocado pieces to the bowl with the sauce. Toss until everything is evenly coated.

    Time: PT5M

  4. Chill the Slaw

    Cover the bowl with plastic wrap and refrigerate the slaw while you prepare the fish.

    Time: PT0M

  5. Prepare the Butter Slurry

    In a small saucepan melt the butter over low heat. Stir in lemon juice, minced garlic, and chopped dill. Remove from heat once the butter is fully melted and aromatic.

    Time: PT5M

    Temperature: low heat

  6. Season the Fish

    Pat the halibut pieces dry, then season both sides with salt and pepper. Brush the butter‑garlic‑dill slurry generously over each piece.

    Time: PT5M

  7. Preheat the Grill

    Heat the grill (or grill pan) to medium‑high, about 350°F. Place a sheet of foil on the grill and fold up the edges to create a shallow tray.

    Time: PT10M

    Temperature: 350°F

  8. Grill the Fish

    Place the butter‑coated halibut on the foil. Grill for 7‑8 minutes per side, total 15‑20 minutes, until the internal temperature reaches 135‑140°F and the flesh flakes easily with a fork.

    Place a portion of grilled fish on each tortilla, top with a generous scoop of avocado slaw, and serve immediately.

    Time: PT5M

Frequently Asked Questions

Everything you need to know about this recipe

Q

What is the cultural significance and history of fish tacos in Mexican‑American cuisine?

A

Fish tacos originated on the West Coast of the United States, especially in Southern California, where Pacific fish were combined with Mexican tortilla traditions. They have become a staple of coastal Mexican‑American fare, celebrated for their light, fresh flavors and quick preparation.

cultural
Q

What are the traditional regional variations of fish tacos in the Pacific Northwest?

A

In the Pacific Northwest, chefs often use locally caught fish like halibut or salmon, add a creamy avocado or cabbage slaw, and sometimes incorporate dill or citrus‑forward sauces, reflecting the region’s abundant seafood and farm‑to‑table ethos.

cultural
Q

How is fish traditionally served with tacos in Mexican cuisine?

A

Traditional Mexican fish tacos are usually grilled or battered, placed on corn tortillas, and topped with a simple cabbage slaw, fresh cilantro, a squeeze of lime, and sometimes a drizzle of crema or salsa verde.

cultural
Q

What occasions are fish tacos commonly associated with in Mexican‑American culture?

A

Fish tacos are popular at casual gatherings, beach picnics, summer barbecues, and weekend family meals, often served as a fun, quick‑cook option that feels festive yet easy.

cultural
Q

What makes the avocado slaw in this recipe special compared to standard taco slaws?

A

The slaw blends mashed avocado into a creamy mayo‑sour‑cream base, adding richness and a subtle buttery texture that balances the bright lime and spices, creating a unique, velvety topping unlike typical vinaigrette slaws.

cultural
Q

What are the most common mistakes to avoid when making the fish tacos from Marcy Inspired?

A

Common errors include overcooking the halibut, not applying enough butter slurry (which keeps the fish moist), and slicing the cabbage too thick, which can make the slaw crunchy and overpower the fish.

technical
Q

Why does this fish taco recipe use a butter‑garlic‑dill slurry instead of a traditional dry rub?

A

The butter slurry melts into the fish as it grills, infusing it with moisture, garlic flavor, and fresh dill while creating a light crust; a dry rub would not provide the same buttery richness and could dry out the delicate halibut.

technical
Q

Can I make the fish tacos ahead of time and how should I store them?

A

Yes. Prepare the slaw and keep it refrigerated for up to 24 hours. Grill the fish, let it cool, then store in an airtight container in the fridge for 2 days. Reheat gently before assembling, and keep tortillas wrapped to stay soft.

technical
Q

What does the YouTube channel Marcy Inspired specialize in?

A
