Make a rich and indulgent garlic butter sauce for your air fryer salmon using a food processor. Blend together ingredients like garlic, butter, lemon juice, and herbs like parsley and dill. Coat the salmon fillets with this flavorful sauce and let them marinate for a while. Then, place the marinated salmon in the air fryer and cook until it is perfectly cooked and infused with the garlic butter flavors. Serve the salmon over a bed of mashed potatoes or pasta and drizzle with the remaining garlic butter sauce for a decadent meal.
