Prepare the Fish:
Pat the fish fillets dry with paper towels to remove any excess moisture.
In a shallow dish, combine flour, lemon pepper seasoning, garlic powder, salt, and pepper.
In another shallow dish, pour the buttermilk.
In a third dish, add the cornmeal.
Dredge the Fish:
Dip each fish fillet into the buttermilk, then dredge it in the seasoned flour mixture.
Next, dip the fillet back into the buttermilk, then coat it with the cornmeal for a crispier texture.
Fry the Fish:
Heat vegetable oil in a large skillet over medium-high heat.
Once the oil is hot (about 350°F or 175°C), add the fish fillets. Fry for about 3-4 minutes per side, or until golden brown and crispy.
Remove the fish from the skillet and place on paper towels to drain any excess oil.
Make the Lemon Garlic Sauce (Optional):
In a small bowl, mix mayonnaise, lemon juice, garlic powder, salt, and pepper until smooth.
Assemble the Tacos:
Warm the tortillas in a skillet or microwave.
Place the crispy fried fish fillets onto each tortilla.
Top with shredded cabbage, sliced avocado, and a drizzle of the lemon garlic sauce (if using).
Garnish with fresh cilantro leaves and a squeeze of lime juice.
Serve:
Serve the fried lemon pepper fish tacos immediately, with extra lime wedges on the side.
