Recommended Tools
- Grilling Baskets: These baskets make it easy to grill the halibut already cut up, and ready to go. I like cutting it before cooking so the marinade can soak into all the sides, but you can grill whole filets if you want, and chunk it after cooking.
- Taco Holders: Means you can pre-assemble tacos, and have them stay together. A fun extra!
- Grilling Tongs: Great for grilling the tortillas before assembling so you get awesome tacos!
How to Make Citrus Marinated Halibut Fish Tacos
Step 1: Marinate the Halibut
In a bowl, whisk together the orange juice, lime juice, lemon juice, garlic, green onion, cilantro, and red pepper flakes. Add the chunked halibut to the marinade, ensuring each piece is well-coated. Cover and refrigerate for at least 30 minutes, but no longer than an hour to prevent the fish from becoming mushy.
Step 2: Make the Chimichurri
While the fish is marinating, prepare the chimichurri. In a small bowl, mix together the melted butter, parsley, cilantro, red onion, red pepper flakes, and red wine vinegar. Stir until well combined and set aside.
Step 3: Grill the Halibut
Preheat your grill to 400°F. Lightly spray a grill basket with non-stick spray and place the marinated halibut inside. Grill for 5-6 minutes, flipping halfway through, until the fish is opaque and flakes easily with a fork.
Step 4: Assemble the Tacos
Warm the taco shells on the grill or in a skillet. Fill each shell with grilled halibut, a drizzle of chimichurri, a sprinkle of crumbled Cotija cheese, and fresh mango chunks.
Serving Suggestions & Variations
- Add some crunch – Top with shredded cabbage or radishes for extra texture.
- Extra heat – Add a drizzle of spicy aioli or hot sauce.
- Avocado boost – Sliced avocado or a dollop of guacamole would complement these tacos beautifully.
- Tropical twist – Swap mango for pineapple or papaya for a different fruity touch.
