What You'll Learn

Preheat the air fryer
Preheating your air fryer is an important step when cooking frozen asparagus. While preheating is not always necessary when using an air fryer, it is crucial when cooking frozen vegetables. If you skip the preheating step, your asparagus may turn out soggy, as it will steam instead of achieving the desired crisp or roasted texture. Therefore, make sure to preheat your air fryer to a temperature of around 400°F (204°C) for about 5 minutes.
During the preheating phase, you can toss the frozen asparagus spears with the remaining ingredients, such as olive oil, salt, pepper, and any desired spices or seasonings. However, if you are using coarse sea salt, it is recommended to add it at the end as a finishing touch for added crunch and a pleasing presentation.
By preheating your air fryer, you ensure that your frozen asparagus will cook evenly and achieve the desired crispy texture. This step may vary slightly depending on the model and size of your air fryer, so adjust the temperature and timing accordingly.
Once preheated, you can proceed to the next step of placing the seasoned asparagus in the air fryer basket and cooking it for the recommended time.

Season the asparagus
Seasoning the asparagus is a key step in cooking frozen asparagus in an air fryer. The right combination of seasonings can bring out the vegetable's natural flavour and make it a tasty side dish.
A light coating of oil is recommended to help achieve the desired crispiness. Olive oil is a popular choice, but alternatives such as avocado oil or avocado oil spritzer can also be used. It is important to use a small amount of oil, as too much can make the asparagus soggy.
Salt and pepper are commonly used to season asparagus. For an extra punch of flavour, garlic powder, red pepper flakes, paprika, onion powder, or nutritional yeast can be added. If you're feeling fancy, you can use garlic salt instead of regular salt to add some heat.
For those who enjoy cheese, grated or shredded Parmesan can be sprinkled on top. To make it vegan-friendly, you can use vegan Parmesan cheese. A squeeze of lemon juice can also be added for a hint of citrus.
You can customise the seasonings to your personal preference and create a unique flavour profile for your air-fried asparagus.

Cook the asparagus
First, take your frozen asparagus spears straight from the freezer—no thawing required. Place them in a mixing bowl or directly into the basket of your air fryer. Drizzle or brush the asparagus with olive oil, avocado oil, or melted butter. Be careful not to add too much oil, as this can make the asparagus soggy. Next, season the asparagus with salt, pepper, and any other desired spices or seasonings, such as garlic powder, onion powder, red pepper flakes, paprika, or nutritional yeast. You can also add grated or finely minced garlic to replace garlic powder. Toss the asparagus to ensure they are evenly coated with oil and seasonings.
Now, it's time to cook the asparagus. Preheat your air fryer to 380-400°F (193-204°C). Place the seasoned asparagus in a single layer in the air fryer basket. If your air fryer is small, you may need to cook the asparagus in batches. Set the timer for 8-10 minutes, but keep an eye on the asparagus, as the exact cooking time will depend on the thickness of the spears and the model of your air fryer. For thin spears, 6-7 minutes may be enough. Halfway through the cooking time, shake or toss the asparagus to ensure even cooking.
Your asparagus is ready when the stalks are fork-tender and the tips are slightly crisp. Remove them from the air fryer and serve immediately. You can garnish with a squeeze of lemon juice, grated parmesan cheese, chopped nuts, or a drizzle of balsamic glaze. Enjoy!

Add toppings and serve
Once your asparagus is cooked to your liking, it's time to add toppings and serve.
A squeeze of lemon juice is a popular choice to add a hint of citrus to your asparagus. You can also add lemon zest for an extra zesty kick.
For a savoury, nutty flavour, sprinkle some grated or shredded parmesan cheese on top. If you want to keep the dish vegan, you can use vegan or paleo parmesan.
If you're feeling spicy, add some red pepper flakes or crushed black pepper. A drizzle of balsamic glaze or vinegar will add a sweet and tangy flavour.
For a crunchy texture, top your asparagus with chopped nuts or coarse sea salt.
You can also add a creamy element by serving the asparagus with a dip, such as bacon aioli, or a sauce, such as lemon herb tahini.
Simply season with salt and pepper, or add garlic powder, onion powder, or paprika for an extra kick of flavour.
There are endless combinations of toppings to add to your air-fried asparagus, so get creative and enjoy!
