How to Make Mahi Mahi Tacos

SEASON FISH. Pat dry the mahi mahi filets with a clean paper towel and drizzle cooking oil onto the fillets. Season both sides generously with the blackening seasoning.

BLACKEN FISH. Place a large saute pan over medium-high heat and add butter and oil. When the oil is hot, add the mahi mahi fillets. Cook, undisturbed, for 3-4 minutes, until golden brown on one side. Then,  carefully flip the fish over and continue to cook for 2-3 minutes, or until opaque and completely cooked through.

Variations + Substitutions

• Fish: Wondering what fish is best for fish tacos? A mild-tasting white fish is best. Try cod, snapper, halibut, or tilapia as substitutes. Just be mindful that cooking times will vary.
• Additional Toppings: Need more fish taco topping ideas? Add your favorite hot sauce, guacamole, lime wedges, pico de gallo, or pineapple salsa.

Tips To Nail the Recipe

• Cook fish skin-side down first. Use fresh or frozen fillets. Make sure frozen fillets are thawed before cooking
• Warm the tortillas on the stove or grill for the best taste and texture.
• Keep the tortillas warm by wrapping them up in a clean kitchen towel or aluminum foil.
