6. Cooking Tips
- For best results and even crisping, shake or flip food halfway through the cooking cycle.
- Use the extender ring for larger items like whole chickens or turkeys to ensure proper air circulation.
- Lightly spray food with oil for extra crispiness, especially for fresh vegetables or homemade fries.
- The unit can cook frozen foods without prior thawing, but cooking times may need to be adjusted.
- When cooking multiple items on different racks, consider their individual cooking times and temperatures. Items requiring higher temperatures or longer cooking times may be placed on the top rack.
