💡 Chef’s Secrets for Maximum Flavor
- Always pat the salmon skin and flesh completely dry to prevent steaming and guarantee a delectable golden-brown sear.
- Do not overcrowd the air fryer basket; if necessary, cook the salmon and asparagus in two separate batches to maintain proper airflow and crispness.
- Use a digital instant-read thermometer inserted into the thickest part of the salmon to prevent overcooking and keep the fish succulent.
🧊 Storage & Reheating Instructions
Store leftover salmon and asparagus in an airtight container in the refrigerator for up to 3 days. Freezing is not recommended as it degrades the delicate texture of both the fish and fresh asparagus.
