Paleo Fish Tacos with Mango Salsa — Gluten-Free in 25 Minutes

Just because you follow a grain-free diet doesn’t mean you have to miss out on delicious fish tacos. These Paleo fish tacos come together quickly and are packed with bright, balanced flavors. Eat them with grain-free tortillas or skip the wrap entirely and serve in lettuce cups for a Whole30-friendly version. The crunchy, tender fish and fresh mango salsa taste like a treat—without the guilt.

I used Siete grain-free tortillas as a convenient Paleo-friendly option, but you can absolutely make your own or use any grain-free wrap you prefer. If you have a gas stove, briefly heating the tortillas directly over the flame to char the edges adds a smoky depth that pairs wonderfully with the fish.

If you want a Whole30 version, simply skip the tortillas. Butter lettuce, romaine leaves, collard wraps, or a bed of greens all make excellent vessels for the fish and mango salsa. A lettuce-wrapped taco filled with bright mango and creamy avocado is an easy way to enjoy this dish while staying compliant.

The great thing about this recipe is how adaptable it is—use it as a framework and swap in what you have on hand. If you prefer pineapple to mango, make a pineapple salsa. If you already have shredded lettuce, use it. Leave out any toppings you don’t like; recipes should be helpful, not restrictive.

For the fish breading I combine coconut flour and tapioca flour. Tapioca adds extra texture and helps the coating cling, but the recipe still works well with just coconut flour if you don’t have tapioca on hand. Both flours are common alternatives in grain-free and Paleo cooking and create a light, crisp coating when cooked in coconut oil.

Change up the fillings to suit your tastes: shredded cabbage, sliced avocado, microgreens, fresh cilantro, or thinly sliced jalapeño for heat. The mango salsa is the star—sweet, tangy, and bright—but it stores well if you double the batch. Keep leftover salsa refrigerated in an airtight container for up to seven days.

• Prep Time: 15 minutes
• Cook Time: 10 minutes
• Total Time: 25 minutes
• Yield: Serves 3-4

Ingredients

For the Tacos:

• 8 grain-free tortillas (or lettuce/collard wraps)
• 1 pound halibut or cod, cut into 1″ pieces
• 1 cup coconut oil (for frying)
• 1 egg, beaten
• 1/2 cup shredded purple cabbage
• 1/2 cup tapioca flour (optional)
• 1/4 cup coconut flour
• 1 teaspoon garlic powder
• 1/2 teaspoon salt
• Optional toppings: sliced jalapeño, 1/2 cup diced cilantro, microgreens, sliced avocado

For the Mango Salsa:

• 2 mangos, peeled and diced
• 1/2 cup diced red onion
• 1/4 cup finely chopped cilantro
• 1/2 jalapeño, finely diced (optional)
• 1/2 teaspoon salt
• Juice of 1 lime

Instructions

1. Dice the fish into 1-inch pieces.
2. Combine coconut flour, tapioca flour (if using), garlic powder, and salt in a shallow bowl next to the beaten egg.
3. Heat the coconut oil in a large skillet over medium-high heat.
4. Dip each piece of fish into the beaten egg, then coat evenly in the flour mixture.
5. When the oil is hot, add fish pieces to the pan using tongs, careful not to overcrowd the pan.
6. Cook 1–2 minutes until golden brown on the first side.
7. Flip and cook another 1–2 minutes until cooked through.
8. Remove the fish and place on a paper towel-lined plate to drain any excess oil.
9. Assemble tacos or wraps with fish, cabbage, mango salsa, avocado, and cilantro. Serve immediately.

Notes

Double the mango salsa if you’d like leftovers—stored in an airtight container, it will keep up to seven days in the refrigerator. Avoid crowding the fish in the pan; if necessary, cook in batches and add more coconut oil between batches.
