These air fryer asparagus recipes are easy and packed with flavor. You can use store-bought, or homemade spice blends. I have included recipes for all of them should you want to make your own. It's a great way to ensure an all-natural recipe, and control the salt and sugar as well. Special Tip: If you don't have olive oil spray you can use regular olive oil. Ideally shoot for just 1 teaspoon of olive oil to keep these air fried asparagus spears low calorie and crispy.
