Crisp up frozen asparagus in the air fryer for a quick and easy veggie on busy weeknights! In just 10 minutes, you’ll take frozen vegetables directly from the freezer and turn them into a delicious crisp-tender, side dish!
In the basket of the air fryer (or a separate mixing bowl) toss frozen asparagus spears with olive oil, salt, and pepper. If you want to add spices like garlic or onion powder, do so here, too. Spread in an even layer in the air fryer basket.
Set the air fryer to 400°F. Cook for 8-10 minutes. For thin asparagus spears, you'll need less time, around 6-7 minutes. Toss halfway through. Time may vary depending on the model of air fryer you use. Once they're fork-tender yet slightly crisp, they're ready!
Serve immediately. Garnish with a squeeze of lemon juice, grated parmesan cheese, or chopped nuts as desired. See the post for more serving suggestions, too!
Notes
Air Fryer: this recipe was tested with a 4-quart Ninja air fryer. The exact cook time may vary depending on the model of your air fryer.
Storage: store any leftovers in an airtight container in the fridge for 3-4 days. Reheat in the air fryer at 400°F until crisp and warm.
You can use a different size bag of frozen asparagus, just be sure to not overcrowd the pan or they will steam instead of crisp. If they're too piled, make two batches.
