Make a delicious pesto crust for your air fryer salmon using a food processor. Blend together fresh basil leaves, garlic, pine nuts, Parmesan cheese, and olive oil until you have a smooth and vibrant pesto sauce. Spread the pesto generously over the salmon fillets, then place them in the air fryer and cook until the crust turns golden brown and crispy. The result is a flavorful and aromatic salmon dish that will transport you to Italy. Serve it with a side of roasted potatoes or a fresh salad for a complete meal.
