Choosing the Perfect Fish for Your Tacos
The star of any fish taco is, naturally, the fish! For grilling, you want a firm, white-fleshed fish that won’t fall apart on the grates. Here are some excellent choices:
- Mahi-Mahi: A fantastic option, known for its mild, sweet flavor and firm texture. It holds up beautifully on the grill.
- Grouper: Another superb choice, offering a delicate, flaky texture once cooked and a mild, slightly sweet taste.
- Cod: A popular and readily available fish, cod has a mild flavor and can be grilled successfully if handled with care.
- Halibut: Pricier but exquisite, halibut offers a firm, meaty texture and a sweet, delicate flavor.
- Snapper: Known for its mild, slightly sweet flavor and moist, flaky flesh.
Aim for fillets about 3/4 inch thick. Thicker fillets will take longer to cook, while thinner ones might cook too quickly and dry out. Always choose fresh fish with a clean, ocean smell and clear, bright eyes if buying whole.

Ingredients
These tacos feature a delightful blend of fresh, vibrant ingredients and a simple yet flavorful crema sauce. Each component plays a crucial role in creating the overall exquisite taste profile.
- 1 1/2 pounds firm fleshed fish fillet (about 3/4 inch thick; grouper or mahi-mahi are excellent choices)
- Olive oil (for brushing fish and grill grates)
- 3/4 teaspoon garlic salt
- 1 teaspoon paprika
- 2 ears corn (shucked)
- 2 tomatoes (diced into 1/4″ pieces)
- 2 tablespoons finely chopped cilantro
- 12 corn tortillas
- 2 cups shredded cabbage (a pre-made coleslaw mix works beautifully for convenience)
- 2 limes (cut into wedges for serving)
- 1/4 cup pepitas (roasted pumpkin seeds, for a delightful crunch)
For the Crema Sauce
This simple yet flavorful crema sauce adds a cool, creamy, and slightly spicy counterpoint to the grilled fish. It’s incredibly easy to whisk together while your grill heats up.
- 1 cup light sour cream
- 1/2 teaspoon paprika
- 1/2 teaspoon garlic salt
- 1/4 teaspoon ancho chili powder (regular chili powder can be substituted if ancho is not available)
Instructions
Follow these straightforward steps to create your mouth-watering grilled fish tacos. Precision and timing are key, especially when grilling the fish, to ensure a tender and juicy result.
- Prepare Your Grill: Preheat your outdoor grill to medium-high heat. Ensure your grates are clean to prevent sticking.
- Pre-cook and Oil the Corn: For perfectly tender and slightly charred corn, roll each ear in a damp paper towel and microwave for 2 minutes. This par-cooks the corn, making it juicy and easier to grill. After microwaving, brush each ear generously with olive oil.
- Season the Fish: Lightly brush your firm-fleshed fish fillets with olive oil. Season evenly with garlic salt and paprika on both sides. This simple seasoning enhances the fish’s natural flavors without overpowering them.
- Whisk the Crema Sauce: In a small bowl, combine the light sour cream, paprika, garlic salt, and ancho chili powder. Whisk until smooth and well combined. Set aside to allow the flavors to meld.
- Grill to Perfection: Brush your grill grates thoroughly with olive oil. Place the oiled corn directly onto the grill, rotating frequently to achieve an even char and tenderness. Simultaneously, add the seasoned fish fillets to the grill. Grill for approximately 3 minutes per side, being careful not to overcook the fish, as it can become dry. The fish should flake easily with a fork when done. During the final minute of fish cooking, place the corn tortillas directly on the grill grates, flipping them halfway through until they are warm and slightly pliable.
- Assemble Your Tacos: Once the corn is cooked, use a serrated knife to carefully cut the kernels off the cob. Now it’s time to assemble your delicious tacos! Lay out a warm corn tortilla, add a bed of shredded cabbage, a succulent piece of grilled fish, a generous spoonful of the homemade crema sauce, a sprinkle of roasted corn kernels, some diced tomato, a squeeze of fresh lime juice, and finally, a scattering of crunchy pepitas. Serve immediately and enjoy!

Tips for Grilling Perfect Fish Every Time
Grilling fish can be intimidating, but with a few simple tricks, you’ll achieve beautifully cooked, flaky fish every time:
- Clean Grates are Key: Always start with clean grill grates. Any leftover residue will cause your fish to stick.
- Oil Generously: Don’t be shy with the oil! Brush your fish with olive oil and then oil the grates thoroughly just before placing the fish down. Use a paper towel dipped in oil and held with tongs to rub the hot grates.
- High Heat, Quick Cook: Fish cooks quickly, especially firm fillets like mahi-mahi or grouper. Medium-high heat is ideal to get a good sear without overcooking the inside.
- Don’t Overcrowd: Give your fish space on the grill. Overcrowding can lower the grill temperature and steam the fish instead of searing it.
- Leave it Alone: Once you place the fish on the grill, resist the urge to move it for the first few minutes. This allows a crust to form, which helps it release easily when you go to flip.
- Use a Fish Spatula: A wide, thin metal spatula specifically designed for fish makes flipping much easier and minimizes the risk of breaking delicate fillets.
- Check for Doneness: Fish is cooked when it flakes easily with a fork at its thickest part. It should be opaque throughout.
Customization and Variations for Your Tacos
While our recipe is fantastic as is, feel free to get creative and customize your grilled fish tacos to your liking:
- Spice it Up: Add a pinch of cayenne pepper or a dash of your favorite hot sauce to the crema for an extra kick. You could also sprinkle chili flakes on the fish while seasoning.
- Alternative Toppings:
- Avocado: Sliced or diced avocado, or a dollop of fresh guacamole, adds a rich, creamy element.
- Salsa: A vibrant pico de gallo, mango salsa, or even a simple store-bought salsa can elevate the freshness.
- Pickled Onions: Quick pickled red onions provide a lovely tangy crunch.
- Cheese: A sprinkle of cotija or Monterey Jack cheese can add another layer of flavor.
- Jalapeños: Freshly sliced or pickled jalapeños for those who love heat.
- Different Greens: Instead of shredded cabbage, try a spring mix, finely chopped romaine lettuce, or even arugula for a peppery note.
- Tortilla Choices: While corn tortillas are traditional, flour tortillas can also be used. For an extra layer of flavor, lightly char them on the grill or in a dry skillet.
- Vegetarian Option: For a delicious vegetarian alternative, grill thick slices of halloumi cheese, portobello mushrooms, or seasoned firm tofu instead of fish.
Serving Suggestions for a Complete Meal
Turn your grilled fish tacos into a full meal with these delicious accompaniments:
- Classic Rice and Beans: Simple cilantro-lime rice and black beans are always a perfect pairing for tacos.
- Mexican Street Corn Salad: Take your roasted corn a step further by mixing it with cotija cheese, lime juice, chili powder, and cilantro for a refreshing side dish.
- Fresh Salad: A simple green salad with a light vinaigrette provides a nice contrast.
- Agua Fresca or Margaritas: Complete the fiesta with a refreshing beverage like a homemade agua fresca (hibiscus, horchata, or lime) or a classic margarita.
