The blooming onion is a popular appetizer that originated in America and has become a favorite dish at many restaurants. This deep-fried onion is not only delicious but also visually stunning, making it a perfect choice for impressing your guests or simply treating yourself to a tasty snack. However, deep-frying can be messy and time-consuming. Luckily, you can achieve the same crispy and flavorful result by using an air fryer.

Using an air fryer to cook a blooming onion is a healthier alternative to deep-frying. The air fryer functions by circulating hot air around the food, creating a crispy outer layer while allowing the inside to remain tender. This cooking method significantly reduces the amount of oil used, making it a guilt-free option for onion lovers.

To cook a blooming onion in the air fryer, start by selecting a large onion with tightly packed petals. Cut off the top of the onion and peel the outer layer, leaving the root intact. Then, make vertical cuts starting from the top, stopping about 1/2 inch from the root. Gently spread the petals apart to form a blooming effect. Next, season the onion with your desired spices, such as garlic powder, paprika, or cayenne pepper, to add extra flavor.

Preheat the air fryer at 375°F (190°C) before placing the seasoned blooming onion inside the fryer basket. Cook for approximately 10-15 minutes, or until the outer layer becomes golden brown and crispy. Remember to flip the onion halfway through to ensure even cooking. Once the blooming onion is cooked to perfection, remove it from the air fryer and let it cool for a few minutes before serving.

Now you can enjoy a restaurant-style blooming onion right at home, thanks to your air fryer. Serve it with a dipping sauce of your choice, such as ranch dressing or spicy aioli, to enhance the flavors even further. Whether you’re hosting a party or simply craving a delicious snack, cooking a blooming onion in the air fryer is a simple and satisfying way to satisfy your cravings.

Choose the Right Onion

When it comes to making a blooming onion in the air fryer, choosing the right onion is key. While any type of onion can be used, it is recommended to opt for a larger variety such as a Vidalia onion. These onions are known for their sweet and mild flavor, which complements the crispy texture of the blooming onion perfectly.

Before starting the cooking process, make sure to select an onion that is firm and free from any soft or mushy spots. The onion should also have a tight and intact skin, as this helps to hold the petals together during cooking.

Prep the Onion

To start, you’ll need a large sweet onion, such as a Vidalia onion. Peel off the outer skin, making sure to remove any loose or dry layers. Then, trim the top and bottom of the onion, leaving the root intact. This will help keep the onion together when cutting it later.

Next, place the onion on a cutting board, root side down. With a sharp knife, make vertical cuts down the onion, stopping about half an inch from the root. The cuts should be evenly spaced, and you can use your fingers to hold the onion in place while cutting.

After making the vertical cuts, it’s time to create horizontal cuts. Rotate the onion 90 degrees, so the cuts are perpendicular to the ones you just made. Again, make vertical cuts down the onion, stopping about half an inch from the root. This will create a checkerboard pattern of cuts all over the onion.

Once you’ve made all the cuts, gently fan out the onion to reveal its blooming shape. If you want a smaller blooming onion, you can remove a few layers from the center, but be careful not to separate the onion completely.

Finally, soak the onion in cold water for about 10 minutes. This will help remove any excess starch and make it easier to coat the onion later. After soaking, pat the onion dry with paper towels to remove any excess moisture.

Create the Batter

Before you can cook a blooming onion in the air fryer, you need to create a delicious batter to coat the onion. The batter is what gives the onion its crispy texture and savory flavor. Here’s how to make it:

Ingredients:

  1. 1 large onion
  2. 1 cup of all-purpose flour
  3. 1 teaspoon of paprika
  4. 1 teaspoon of garlic powder
  5. 1/2 teaspoon of salt
  6. 1/4 teaspoon of black pepper
  7. 1 cup of buttermilk

Instructions:

  1. Start by peeling the onion and cutting off about 1/2 inch from the top
  2. Use a sharp knife to make vertical cuts in the onion, starting from the top and stopping about 1/2 inch from the bottom. Make about 16 evenly spaced cuts.
  3. In a bowl, whisk together the flour, paprika, garlic powder, salt, and black pepper. This will be your dry mixture.
  4. Pour the buttermilk into a separate bowl. This will be your wet mixture.
  5. Dip the onion into the dry mixture, making sure it’s coated evenly. Shake off any excess.
  6. Next, dip the coated onion into the buttermilk, again making sure it’s coated evenly.
  7. Return the onion to the dry mixture and coat it again.
  8. Place the battered onion in the air fryer basket, making sure it stands upright and the cuts are facing upwards.

Tip: If you don’t have buttermilk, you can make a substitute by combining 1 cup of milk with 1 tablespoon of vinegar or lemon juice. Let it sit for 5 minutes before using.

Before you begin cooking your blooming onion in the air fryer, make sure to set it up properly. Follow these steps:

1. Preheat the Air Fryer

2. Assemble the Air Fryer Basket

Place the air fryer basket inside the air fryer and make sure it is clean and free of any obstructions. If needed, give it a quick wipe with a damp cloth. Make sure the basket is securely in place before you proceed.

3. Apply Cooking Oil or Spray

Lightly coat the air fryer basket with cooking oil or cooking spray. This will prevent the blooming onion from sticking to the basket and also help in achieving a crispy outer layer.

Choose a cooking oil with a high smoke point, such as vegetable oil or canola oil. Alternatively, you can use an oil spray specifically formulated for air frying.

Remember not to use too much oil, as it may lead to excessive smoke and a greasy result.

4. Adjust the Air Fryer Settings

Set the cooking time and temperature according to the recipe instructions. The cooking time for a blooming onion in an air fryer is typically around 12 to 15 minutes, but it may vary depending on the size and thickness of the onion.

Refer to the manufacturer’s instructions for your specific air fryer model on how to adjust the cooking settings.

Once you have set up your air fryer, you can proceed with preparing your blooming onion for cooking.

Remember to always exercise caution when handling the air fryer, as it can get hot during the cooking process. Follow the manufacturer’s safety guidelines and use oven mitts or tongs when necessary.

Cook the Blooming Onion

Now that you’ve prepared the blooming onion and preheated the air fryer, it’s time to cook it to perfection. Follow these simple steps:

Step 1: Place the Onion in the Air Fryer

Carefully place the prepared blooming onion in the air fryer basket. Make sure it fits comfortably without crushing any of the petals.

Step 2: Set the Cooking Time and Temperature

Set the air fryer to 400°F (200°C) and the cooking time to 10 minutes. This will give you a perfectly crispy and golden brown blooming onion.

Step 3: Cook the Onion

Press the “Start” button to begin cooking. The air fryer will circulate hot air around the onion, cooking it evenly.

Step 4: Flip the Onion

At the 5-minute mark, carefully flip the onion using tongs or a spatula. This will ensure that both the top and bottom sides get equally crispy.

Step 5: Check for Doneness

After the 10 minutes are up, carefully open the air fryer and check the blooming onion for doneness. The petals should be crispy and golden brown.

Step 6: Remove and Serve

Once the blooming onion is cooked to your liking, use tongs to carefully remove it from the air fryer basket. Place it on a serving plate or platter.
