How to Make Grilled Fish Tacos

Prepare the Fish: In a mixing bowl, blend together chili powder, lime juice, olive oil, cumin, onion powder, garlic powder, salt, and pepper to form a vibrant marinade. Rub this mixture over your mahi-mahi or halibut, ensuring it’s evenly coated. Let it marinate for 20-30 minutes to absorb those delicious flavors.
Make the Slaw: In another bowl, combine reduced-fat sour cream, low-fat mayonnaise, cilantro, lime zest, lime juice, sugar, salt, and pepper. Stir until the mixture is smooth and creamy. Gently fold in the finely shredded cabbage, and refrigerate the slaw until you’re ready to assemble the tacos.
Grill the Fish: Preheat your grill to medium-high heat, ensuring the grates are well-oiled to prevent sticking. Grill the marinated fish for about 3-5 minutes on each side until it flakes easily with a fork and has lovely grill marks. Remove from heat and flake into large pieces.
Assemble Tacos: Warm your corn tortillas on the grill for a few seconds on each side. Serve the grilled fish generously on top of the tortillas, and add a heaping scoop of the creamy cabbage slaw for that perfect crunch.

Optional: Top with avocado slices and a squeeze of fresh lime for an extra punch of flavor.

Freezer: You can freeze the marinated fish before grilling for up to 3 months. Just thaw in the fridge overnight before grilling. Avoid freezing the slaw, as it will become soggy after thawing.

Reheating: When ready to enjoy leftovers, reheat the fish in the oven at 350°F for about 10-15 minutes until warmed through. Avoid microwaving to keep the texture intact.

Make-Ahead: Marinated fish can be prepared up to 1 hour in advance, while the slaw can be made and stored in the fridge for up to 3 days prior to serving your grilled fish tacos.

Make Ahead Options
