Step-by-Step Instructions
💡 Chef Tips for Best Results
- ✓Never overcrowd the air fryer basket—leaving space around each piece allows 360° superheated air to crisp every side.
- ✓Use a non-aerosol olive or avocado oil mister rather than propellant sprays to protect your non-stick basket coating.
- ✓Reheat leftovers in the air fryer at 360°F for 3–4 minutes to restore 100% of the original crunch.
🧊 Storage, Freezing & Safe Reheating
Refrigerate leftovers in an airtight container at 40°F (4°C) for up to 4 days, or freeze for up to 2 months. Reheat to 165°F (74°C) before serving.
