If you like a bit of heat, this spicy Cajun air fryer salmon recipe is perfect for you. Using a food processor, blend together Cajun spices like paprika, cayenne pepper, garlic powder, and onion powder to create a flavorful rub for the salmon. Coat the salmon fillets with the Cajun rub and let them sit for a while. Then, place the salmon in the air fryer and cook until it becomes blackened and spicy. Serve it with a cooling cucumber and yogurt sauce to balance out the heat.
