Grill… Air-fry… OR Oven-Roast Asparagus
Just HOW you cook the asparagus is up to you… You can grill asparagus beautifully on an outdoor grill in just about 8 to 10 minutes. Sure, asparagus spears can fall through grill grates, but that’s why you always put the spears perpendicular to the grates and it shouldn’t be a problem, no matter how thin the spears are.
Popping your asparagus into an air fryer is another great option. If you have an air fryer oven, the spears should fit perfectly in the basket/tray included, but you can also toss them around in a round basket style air fryer too. It takes about 6 to 8 minutes to air fry asparagus at 400ºF.
Finally, of course you could oven-roast your asparagus. Put the spears on a baking sheet and transfer them to a 425ºF oven for about 10 minutes.
No matter which way you cook the asparagus, the timing will depend on how thick or thin the spears are. The only way to know when the asparagus is properly cooked is to give it a taste. So, be prepared to flex on the timing, subtracting time for thin spears and adding a minute or two for really thick spears.
