Timing by Spear Thickness

• Thin spears: Check at 5 minutes.
• Medium spears: Cook 6 to 8 minutes.
• Thick spears: Cook 8 to 10 minutes.
• Start checking early because air-fryer power and basket size vary.
• Cook a second batch instead of stacking spears.

Storage and Reheating

• Refrigerate cooled leftovers up to 3 days.
• Reheat at 375 degrees F for 2 to 3 minutes.
• Add fresh lemon only after reheating.
• Serve immediately for the best tip texture.

Serve it with Lemon Garlic Baked Cod, Meal Prep Baked Chicken, or Baked Turnip Fries.

Air Fryer Asparagus FAQ

Why is my asparagus limp?

The basket may be crowded, the spears may be wet, or they may have cooked too long.

Do I need parchment?

No. Cooking directly in the clean basket improves airflow and browning.
