How to pick asparagus spears

To ensure you end up with the best-tasting roasted asparagus, you must first start with picking a fresh and flavorful bunch. While selecting fresh asparagus at the grocery store, here are a few tips to keep in mind.

  1. Check for plump, firm stalks that have tightly closed tips.
  2. Inspect the color of the stalk for fading. A good bunch will have strong, unfaded coloring.
  3. Pick a bunch with uniform sizing. Make sure each stalk is roughly the same size and length to ensure even cooking.
  4. When possible, buy in season. Asparagus is at its best from late February to June.

Trimming fresh asparagus

If the store-bought asparagus is not trimmed, don’t worry you can easily do it at home – just chop off the tough ends (the white part).

Once you’ve sliced the tough ends off the asparagus you will want to check to make sure they are relatively similar in length. Line up the tips of the asparagus and trim any pieces that are much longer than the rest. This ensures your asparagus roast evenly.

Note: If you want to snap the woody white ends of the asparagus by hand you can but you can end up accidentally snapping off the green usable part too. Chopping it with a sharp knife is a much better method.

Tools

You’ll need an air fryer to make this recipe. Here are the two that I recommend 

  • Basket style (Phillips 7 QT, 1725W) – easier to flip food but cooks a smaller amount (2-3 servings).
  • Oven-style (Ninja Dual Heat Air Fryer – 1800W) – The oven-style ones usually take more space but what’s unique about this Ninja one is that it flips vertically for easy storage on the countertop. Most importantly, it allows you to cook six chicken breasts, 2 lbs roast, or 4 lbs of fries – perfect for families of 4 or more.

TIPS

  • Choose asparagus that are fresh. Look for vibrant color and tightly closed tips.
  • Don’t forget to trim the white woody ends or else you’ll end up with chewy ends.
  • Dry completely – After rinsing the asparagus, make sure to pat it dry to ensure crispy results.
  • Make sure the asparagus is evenly coated with seasonings.
  • Air fryer cooking times will vary depending on the model used. Always use less time than mentioned in the recipe and add more minutes as needed.
  • No overcrowding – Always arrange food in a single layer and cook in batches if needed.
  • Toss or flip the food halfway during cooking to make sure the food is cooked evenly.

Variations to try

If you are looking to switch up the flavor of this easy air fryer roasted asparagus, here are a few different ways to season them up.

  1. Drizzle with lemon juice or balsamic vinegar for added flavor.
  2. Finish it off with melted butter.
  3. Use red pepper flakes instead of ground pepper.
  4. A dash of smoked paprika also works great on asparagus.
  5. Bacon is a popular option as well to cook as well as serve with asparagus.

Storage tips

Like most air fryer veggies, asparagus tastes best when served immediately.

Refrigerator: You can save the leftovers in the refrigerator for up to 4-5 days – making it perfect for meal prep.

Reheating instructions: To reheat, air fry for 2-3 minutes at 400°F to get the crispy texture back. Don’t use the microwave to reheat – it will soften and become soggy.

Frequently Asked Questions

Should I soak my asparagus before cooking?

No. While you can soak asparagus up to 30 minutes before cooking, it’s an unnecessary step. A quick wash or rinse to remove any grit should suffice.

Overcooking asparagus leaves it tough and stringy which makes eating it unpleasant. Be sure to keep an eye on the time to prevent overcooking the asparagus.

How long does it take to roast asparagus?

The times may vary based on the thickness of your asparagus.
Air-fried asparagus takes about 7-9 minutes of roasting at 400°F.
Oven-roasted asparagus takes about 25 minutes of roasting at 400°F.

What temperature do you use to roast asparagus?

For asparagus in the air fryer as well as the oven, I find 400°F to be the ideal roasting temperature.
