Make the Slaw: In a medium bowl, whisk together the sour cream, mayonnaise, and lime juice until smooth. Add the coleslaw mix, red onion, cilantro, and optional jalapeño. Stir to combine, season with salt and pepper, and refrigerate for at least 15 minutes.
Make the Spice Rub: In a small bowl, mix the smoked paprika, cumin, chili powder, garlic powder, onion powder, kosher salt, and black pepper.
Season the Cod: Cut cod into 1.5 to 2-inch pieces. Pat completely dry with paper towels. In a bowl, toss the cod with olive oil, then sprinkle the spice rub over it, ensuring all pieces are evenly coated.
Preheat Air Fryer: Preheat your air fryer to 400°F (200°C) for 5 minutes.
Cook the Cod: Lightly spray the preheated basket with oil. Arrange the cod in a single layer, not touching. Air fry for 8-12 minutes, flipping halfway, until the fish is opaque and flakes easily. Cook in batches if needed.
Warm Tortillas: While the fish cooks, warm the tortillas in a dry skillet or in the microwave.
Assemble: Place the cooked cod on a warm tortilla, top with a generous amount of the lime slaw, and finish with your favorite garnishes. Serve immediately.
Notes
Ensure cod fillets are patted completely dry with paper towels. This is the most important step for achieving a crispy, non-soggy result in the air fryer.
