How to Make Grilled Mahi Mahi Fish Tacos

Step 1: Season and Prep the Fish

Start by drizzling your mahi mahi (or cod) fillets with olive oil, ensuring both sides get a light coating. Generously sprinkle over the chili powder, cumin, paprika, cayenne, salt and pepper, rubbing the spices in gently for full coverage and maximum flavor. This simple step infuses the fish with warmth and sets the stage for those irresistible, smoky grill marks.

Step 2: Grill to Perfection

Preheat your indoor or outdoor grill to medium-high heat. Lay the seasoned fish directly onto the grates and grill for about 5–6 minutes per side. You’re aiming for a golden-brown crust and easy flakiness—the fish should lift from the grill with ease and begin to flake apart in large, moist pieces.

Step 3: Brighten It Up

Once your grilled fish is cooked, remove it to a platter and immediately squeeze fresh lime juice all over the top. This step brightens up those smoky flavors and keeps everything lively. Taste and adjust with a touch more salt and pepper if needed.

Step 4: Make the Slaw

In a medium bowl, toss together the thinly sliced red cabbage, cilantro, red onion, and lime juice until everything is evenly coated. The lime juice will quickly soften the veggies and bring out their color and flavor, creating a super fresh, crunchy topping that contrasts the fish beautifully.

Step 5: Assemble and Serve

Warm your corn tortillas (I love doing this right on the grill grates for bit of char!), then layer on a bed of slaw, followed by generous chunks of flaky grilled mahi mahi. Top each taco with pico de gallo, creamy avocado slices, and a good drizzle of avocado tomatillo salsa—then serve immediately, while everything is steaming hot and piled high with fresh flavor.

Garnishes

Garnishes are where Grilled Mahi Mahi Fish Tacos truly shine! I like to pile on extra cilantro, a sprinkle of finely diced red onion, gentle crumbles of cotija cheese, and several fresh lime wedges on the side. Don’t be shy—a little extra salsa or a sweet-hot hot sauce gives each taco a final flavor boost.

Side Dishes

Keep things light and festive with sides like Mexican street corn, seasoned black beans, cilantro-lime rice, or a big bowl of fresh fruit. Chilled cucumber salad or a quick watermelon-mint salad are also welcome pairings for hot days or big gatherings.

Creative Ways to Present

Turn taco night into a build-your-own bar by laying out grilled fish, slaw, toppings, and salsas buffet-style—fun for families and perfect for casual parties. For a dramatic flair, serve your Grilled Mahi Mahi Fish Tacos on a big wooden board lined with banana leaves, surrounded by bowls of colorful toppings and edible flowers (bonus points for margaritas on the side!).

Make Ahead and Storage

Storing Leftovers

Leftover grilled fish keeps beautifully in an airtight container in the refrigerator for up to 2 days. Keep the slaw, tortillas, and toppings separate so you can quickly reassemble fresh, unfussy tacos any day of the week.

Freezing

If you have extra cooked fish, wrap it tightly and freeze for up to a month. Let it thaw overnight in the fridge before gently reheating. Note: Fresh slaw and creamy salsas don’t freeze well, so make those fresh each time!

Reheating

Rewarm the fish in a skillet over medium-low heat or briefly in the microwave, just until heated through—avoid overcooking so the mahi mahi stays moist. Warm tortillas on a dry skillet or open flame for that soft, just-made texture.
