About this Recipe
There are so many ways to prepare asparagus: blanching, steaming, sautéing, grilling, or roasting. The most important thing to remember with any cooking method is don’t overcook the asparagus.
Enter the air fryer. I’ve started using my air fryer to roast vegetables and we’ve been very happy with the results. Air frying is quick and easy, and the vegetables taste great. Try air fryer mushrooms or air fryer roasted Brussels sprouts. Pretty much everything you roast in the oven can be air fried in much less time.

How To Buy and Store Asparagus
Not sure you’re choosing the best asparagus? Look for spears that are firm and crisp. The thickness of the stalks isn’t important although some people prefer thin stalks. The buds should be tightly closed and the stalks smooth, not wrinkled. The color may be green, purple, white, or a combination, depending on the variety. Don’t buy asparagus that is olive green or yellowish.
To store, remove rubber bands and place loosely in a plastic bag in the refrigerator for up to two days. The sooner you use the asparagus, the better it will taste.
What you’ll need
- Asparagus: Purchase one pound (roughly) of asparagus. The grocer may bundle the asparagus in varying amounts. A pound of asparagus spears will serve four people. This is an estimate, really, because it depends on how much of the asparagus is trimmed off and how much asparagus you like to eat.
- Olive Oil: Use a minimal amount of oil. If you have an olive oil spray, you could just lightly mist the spears. Olive oil is a heart healthy and flavorful oil but grapeseed or avocado oil are good choices, too.
- Seasoning: Keep it simple with salt and pepper, or add a bit of garlic powder, or any seasoning you like, really. Try not to overpower the wonderful fresh flavor of the asparagus.
- Parmesan Cheese (optional): Shredded or grated Parmesan cheese is an optional seasoning, too. Just a light sprinkling adds a bit of saltiness and flavor.
How to make This Recipe
First of all, I want to give you a few pointers on how to trim asparagus spears. The ends of the spears can be woody and inedible. How much you have to trim off depends on how the asparagus was harvested, whether it was snapped or cut.
If you want all the spears to have a uniform length, line them up and use a sharp knife to cut through all of them at once. If you encounter a lot of resistance and the spears seem tough and woody, cut a little higher up, repeating until you reach the tender part.
The second way to quickly trim asparagus takes the guesswork out. This is our preferred method! Simply bend each spear near the bottom. The woody end should easily snap off. The asparagus seems to “know” where it needs to be trimmed. The downside of this method is that the spears may be different lengths but the upside is that you don’t waste any. This short YouTube video will show you how.
Do you have to peel asparagus?
As long as you remove the woody ends, there is absolutely no need to peel asparagus. There are no “strings” or inedible parts. Peeling is time consuming, wasteful, and unnecessary.
Once it’s trimmed, rinse the asparagus spears under cold running water to remove sand and dirt. If it’s extremely sandy, soak it for a couple of minutes, swishing it through the water. Pay special attention to the buds because they tend to trap dirt.
For this recipe, you’ll want to dry the asparagus spears. Use a clean lint free dish towel or paper towels. If you’re steaming, blanching, or stir frying it, you won’t need to dry it.
Toss the spears with a little oil, and season them with salt, pepper, and garlic powder. If you like, add a couple spoonfuls of shredded Parmesan cheese, too, and toss to coat.
Arrange them in your air fryer basket in an even layer. It’s okay if they overlap a bit.
Air fry them at 380ºF for six to seven minutes, or until crisp tender. Thick spears may take a minute or two longer.
Serve air fryer asparagus with lemon salmon and creamy potato salad. Eat it with your pulled pork sandwich or beer marinated chicken thighs. Serve it as a side with grilled shrimp kabobs or to top a lemon dressed arugula salad. The possibilities are endless.
FAQs
Should you soak asparagus before cooking?
Unless the asparagus is unusually sandy or dirty, a quick rinse should be sufficient. Pay special attention to the buds which tend to trap sand. If you feel it’s necessary, soak the asparagus five minutes in cold water to loosen dirt before rinsing.
How do you keep asparagus crisp?
To keep asparagus crisp before you cook it, store it in the refrigerator. If it’s banded together, cut the bands, and put it loosely in a dry plastic bag. If you like, put the cut ends in a shallow bowl of water or wrap them in a damp cloth but keep the top part of the stalks dry.
To keep cooked asparagus crisp, don’t overcook it. The longer you cook it, the softer it will get. It should be crisp tender and bright green.
Why is my asparagus slimy?
If you’re talking about raw asparagus, I would say that it’s too old or stored in a wet environment. Discard the asparagus if it gets to the point of sliminess, has a bad odor, or is mushy.
While raw asparagus shouldn’t be slimy, neither should cooked asparagus. Overcooking asparagus may cause it to have a slimy texture and a bitter flavor.
Make It Your Own
- Slice it into bite sized pieces (one inch lengths) before cooking. It’s easier to serve and works better for salads. Children may appreciate asparagus more if it’s not served as long spears. You never know, and the goal is to get them to try it. Mine like it in long stalks because I let them eat it with their hands and they feel like they’re breaking the rules.
- Take it up a notch. Add a drizzle of balsamic vinegar reduction. So good! Freshly grated lemon zest and a squeeze of lemon juice is really great, too – similar to these lemon dill green beans.
- Add a sprinkle of fresh herbs to the roasted asparagus. Basil, parsley, dill, chives, summer savory, or lemon balm are especially good. Experiment a little and see what you like best.
- Add more seasoning. Try my all purpose seasoning blend or another of your favorites.
Make-Ahead Ideas
The asparagus can be trimmed up to a day ahead. This recipe is really so very easy that it won’t take you much more than 10 minutes from start to finish.
Storage & Reheating Tips
If you have leftover asparagus, cover and store it in the refrigerator for up to four days. To be honest, I’ve never tried freezing cooked asparagus because I never have much left over. Raw asparagus can be blanched and frozen.
To reheat asparagus, warm it in the air fryer, in a skillet, or in an oven. Individual portions can be reheated in the microwave. Don’t overheat it.
Leftover Love
Make a quiche with leftover air fryer asparagus in place of spinach. Leftover asparagus is a delicious addition to a salad or a grain bowl.
