Do I need to preheat the air fryer?
It helps with browning, especially for thicker spears. I do 2 to 3 minutes at 400°F if my air fryer preheats quickly. If yours takes forever, you can skip it, then start checking for doneness at the low end of the time range and add time as needed.
How do I keep asparagus from getting stringy?
Buy spears that look firm with tight tips. Trim the woody ends (usually 1 to 2 inches). If the bottom looks pale and dry, keep trimming until it looks juicy and green.
Why is my asparagus soggy in the air fryer?
Overcrowding is the usual culprit. When spears stack up, they steam. Cook in a single layer, shake at the halfway mark, and do a second batch if needed. Also, make sure the asparagus is very dry after washing. Water clinging to the spears turns into steam fast at 400°F.
Can I use frozen asparagus?
You can, but it will be softer. Air fry straight from frozen at 400°F for about 10 to 14 minutes, shaking twice. Frozen asparagus releases water, so do not overcrowd. If it looks wet halfway through, quickly blot the basket or spears with a paper towel, then keep cooking. Expect more “roasted veggie” than crisp-tender snap.
Should I add garlic before or after?
Garlic can burn at high heat. Using garlic powder is the easiest. If using fresh minced garlic, mix it with the oil and keep an eye on it, or add it for the last 2 minutes.
