Prep: Trim the woody end of the asparagus about an inch up from the bottom. Rinse and dry the asparagus.
Season: Place the asparagus onto a large plate. Drizzle the olive oil, and balsamic vinegar on top. Add the seasoning then toss around to coat the asparagus.
Cook: Transfer the asparagus spears into the Air fryer basket. Try to get them in a single layer. Set the air fryer at 380F for 7-10 minutes. Mine were cooked perfectly in 8 minutes. Once the time is up, remove the basket.
Serve: Transfer to a plate and serve immediately.
How to roast asparagus in the oven:
Preheat oven to 425°F. Line the seasoned asparagus in a large sheet pan. If you want, you can add the olive oil, salt, and seasonings directly to the sheet pan and spread the asparagus.
Roast them for 10-12 minutes just until they are tender-crisp. You can turn them once halfway through.
Asparagus looks overcooked: Asparagus cooks very quickly, so it is important to keep an eye and take out the asparagus in time. Else it can get soggy and slimy.
