What You'll Learn

How to get the best texture
To get the best texture when cooking crispy green beans in an air fryer, follow these steps:
Firstly, choose the right type of green beans. Thin beans, often labelled as Haricot verts or French cut green beans, are ideal for air frying as they cook quickly and evenly. If you're using fresh beans, wash them thoroughly and remove the ends. You can also use frozen green beans, but be sure to thaw and pat them dry before cooking, as excess moisture will prevent them from getting crispy.
Next, prepare the beans by tossing them with olive oil, avocado oil, or sunflower oil. A little oil goes a long way, and it helps to enhance the flavour of the beans. You can also add seasonings like salt, pepper, onion powder, chili powder, or garlic powder at this stage. It is recommended to use garlic powder instead of fresh garlic, as it may burn in the air fryer.
Now, you're ready to cook the beans. Preheat your air fryer to 400°F. Place the beans in the air fryer basket in a single layer, ensuring they are not stacked or overcrowded. Cooking in two batches may be necessary, depending on the size of your air fryer. Cook for 5-10 minutes, shaking the basket halfway through, until the beans are crisp on the outside and tender on the inside. Thinner beans will cook quicker, so keep an eye on them to avoid overcooking.
Finally, serve the beans immediately while they're still hot and crispy. You can squeeze some fresh lemon juice on top and sprinkle with shredded Parmesan cheese for an extra flavour boost. Enjoy!

Reheating and storing tips
Storing your air-fried green beans is simple. Let them cool down to room temperature, then place them in an airtight container and store them in the fridge. They should last for up to 3–4 days.
If you want to freeze your green beans, let them cool completely and then transfer them to a freezer bag or container.
When reheating your green beans, using an air fryer is the best option to restore their crisp texture. Preheat your air fryer to 350–380°F (or the maximum setting if it doesn't go that high). Place the green beans in the air fryer basket in a single layer and cook for 2–3 minutes. You can also reheat them in the microwave, but this may affect their texture.
If your green beans are dry, you can dredge them in flour, egg wash, and breadcrumbs before reheating to enhance their crispness. Alternatively, you can use a batter made with tapioca starch and rice flour.

Seasoning and flavour combinations
Smoked Paprika and Garlic Powder:
For a flavourful kick, smoked paprika and garlic powder are a perfect combination. The smokiness of the paprika blends beautifully with the savoury notes of garlic. This duo creates a robust and mouth-watering aroma, taking your green beans to the next level.
Salt and Pepper:
A classic combination of salt and pepper is a simple yet effective way to season your green beans. Kosher salt is recommended for a more intense flavour, but any salt variety can be adjusted to taste. Black pepper adds a subtle kick, creating a familiar and comforting taste.
Chilli Oil and Lemon:
For those who enjoy a bit of heat, chilli oil provides a spicy kick to the green beans. A squeeze of fresh lemon juice adds a tangy and bright note to the dish, creating a well-rounded flavour profile. Lemon wedges can also be used as a garnish, offering a punch of citrus flavour when served on the side.
Olive Oil:
Using olive oil as a base for your seasonings is a great way to add depth of flavour. The oil helps the seasonings adhere to the green beans, ensuring each bite is packed with taste.
Onion and Garlic:
Onion and garlic are a match made in heaven, adding depth and savouriness to the green beans. Using these seasonings together creates a warm and inviting flavour profile that pairs well with the natural taste of the beans.
Walnut Miso Parmesan:
For a more indulgent twist, a generous sprinkle of homemade walnut miso parmesan cheese takes these green beans to the next level. This unexpected combination adds a salty, umami-rich dimension to the dish, making it a unique and memorable side.
Experimenting with different seasonings and flavour combinations is a fun way to make air-fried green beans your own. Get creative, and don't be afraid to explore new tastes and combinations!

The best types of green beans to use
When it comes to choosing the best types of green beans to use for your air fryer recipe, there are a few options to consider. Here are some recommendations to help you achieve delicious and crispy results:
French Green Beans
French green beans, also known as Haricot Verts, are a popular choice for air frying. They are longer and thinner than regular green beans, which makes them ideal for quick and even cooking. French green beans are known for their delicious flavour and tender texture when cooked in an air fryer. They are a great option if you're looking for a more elegant presentation or want to impress your guests with a sophisticated side dish.
Fresh Green Beans
Using fresh green beans is another excellent option. You can choose from garden-fresh green beans or look for fresh French green beans at your local market or grocery store. The key to success with fresh green beans is to ensure they are thoroughly washed and cleaned before cooking. This will remove any dirt or dust, ensuring a pure and tasty final product.
Thin Green Beans
If you want to focus on texture, thin green beans are the way to go. Their slender shape allows them to cook evenly and quickly in the air fryer, resulting in a crisp exterior and soft interior. Look for green beans labelled as "French cut" or "Haricot verts" for the best thin variety.
Garden-Snapped Green Beans
For a truly fresh option, you can snap green beans straight from your garden. This ensures the ultimate freshness and allows you to control the size and shape of your green beans. Just be sure to wash them thoroughly to remove any dirt or residue before tossing them in the air fryer.
Frozen Green Beans
While fresh green beans are ideal, you can also use frozen green beans in a pinch. Simply thaw and pat them dry before tossing them in oil and seasoning. Frozen green beans can be a convenient option if you don't have access to fresh ones or want to save time on preparation.
In summary, the best types of green beans to use for your air fryer recipe are French green beans, fresh green beans, thin green beans, garden-snapped green beans, or, if necessary, frozen green beans. Remember to wash and prepare your green beans properly, and always cook them in a single layer in the air fryer to achieve the perfect crispness and texture. Enjoy experimenting with different varieties to find your favourite!

Oil and seasoning application
To make crispy green beans in an air fryer, you'll need to coat your beans in oil and seasonings before cooking. Here's a detailed guide on oil and seasoning application:
Oil Options:
You can use a variety of oils for this recipe, including olive oil, avocado oil, sunflower oil, or any other oil of your choice. Olive oil, especially extra virgin olive oil, is a popular choice due to its rich flavor. However, avocado oil is also highly recommended, as it works great in the air fryer.
Amount of Oil:
The amount of oil you'll need is just enough to lightly coat the green beans. About 2 tablespoons of oil should be sufficient, but you can adjust this amount based on your preference. If you want your beans to be crispier, using less oil can help achieve that result.
Seasonings:
There are endless possibilities for seasoning your green beans to suit your taste preferences. Here are some popular options:
- Salt: Kosher salt or seasoning salt are great choices.
- Pepper: Freshly cracked black pepper adds a bold flavor.
- Garlic: Garlic powder, granulated garlic, or garlic salt can be used. Fresh garlic is not recommended as it may burn in the air fryer.
- Spices: Smoked paprika, onion powder, chili powder, or red pepper flakes can add a kick of heat and flavor.
- Lemon: A squeeze of fresh lemon juice and some lemon zest can brighten up the dish.
Coating the Green Beans:
Place your washed and trimmed green beans in a bowl. Add the oil and chosen seasonings, then toss or mix until the green beans are evenly coated. Be sure to dry the green beans thoroughly before this step to ensure the oil and seasonings stick properly.
Remember, the key to getting crispy green beans is to ensure they are completely dry before adding oil and seasonings. This allows for an even coating and promotes crisping during cooking.
