Cod is mild, flaky and surprisingly satisfying when prepared simply. These wraps keep the fish at the center while adding bright, fresh toppings and a creamy avocado dressing. Because this recipe is paleo-friendly, it avoids gluten—using almond flour or a gluten-free all-purpose flour instead of breadcrumbs—while still delivering a crisp, seasoned coating on the cod.

Why You’ll Love These Paleo Cod Wraps

  • Low in carbohydrates and high in vegetables for a balanced, lighter meal.
  • Cajun seasoning gives the cod a bold flavor that pairs perfectly with the smooth avocado sauce.
  • Quick to prepare: about 15 minutes prep and 10 minutes cook time makes this ideal for busy evenings.
  • Makes roughly six wraps, so you can plan for leftovers or easily scale the recipe.

How to Make Paleo Cod Lettuce Wraps

These wraps are straightforward to assemble. Start by heating a tablespoon of olive oil or avocado oil in a large nonstick skillet over medium‑high heat. While the oil warms, combine the dry coating: almond flour (or gluten‑free all‑purpose flour) and Cajun seasoning. Pat the cod fillets dry with paper towels, then press both sides into the flour and spice mixture so a light coating adheres.

Place the coated cod directly into the hot skillet. Cover the pan and cook for about three minutes per side, depending on the thickness of the fillets, until the fish is opaque and flakes easily with a fork. While the cod cooks, arrange butter lettuce leaves on a platter and slice the red onion, grape tomatoes and avocado.

For the avocado sauce, add one ripe avocado, the juice of half a lime, two tablespoons olive oil and a pinch of salt into a small blender or food processor. Pulse until smooth, or mash the avocado in a bowl and whisk in the remaining ingredients if you prefer a chunkier texture. Drizzle the sauce over the cooked cod and toppings, then squeeze the remaining lime half over the assembled wraps for a burst of acidity.

Tips for Success

  • Thaw the cod in the refrigerator for 12–24 hours if frozen. Slow thawing improves texture and flavor.
  • Make the avocado sauce just before serving to keep it bright green. Avocado oxidizes and will brown if left sitting for too long.
  • If you don’t want to use a blender, mash the avocado and whisk in the lime, oil and salt by hand—the dressing will be slightly chunkier but still delicious.
  • Use butter lettuce, Boston, or large romaine leaves as sturdy, flexible wraps that hold the fish and toppings well.
  • Adjust the Cajun seasoning to taste—start light and add more if you want extra heat.
