This recipe is so simple and quick, it’s become a staple in my kitchen. The best part? You can easily adjust the seasonings to match whatever dish you’re whipping up.

Ingredients List

To whip up these delicious air fryer crispy fried onions, you’ll need just a handful of simple ingredients. Here’s what you’ll gather:

2 large onions, thinly sliced
1 cup buttermilk
1 cup all-purpose flour
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon paprika
Salt to taste
Cooking spray

Make sure your onions are sliced nice and thin; this helps them cook evenly and get that perfect crunch. The buttermilk is a game-changer, soaking up all the flavor and giving the onions that irresistible texture. And don’t skimp on the spices! They really elevate the taste and make these crispy fried onions truly special. Happy cooking!

How to Prepare Air Fryer Crispy Fried Onions

Getting those air fryer crispy fried onions just right is easier than you think! Follow these simple steps, and you’ll have a crunchy, flavorful topping that will impress everyone at the table. Let’s dive in!

Soaking the Onions

First things first, let’s soak those sliced onions in buttermilk. This step is crucial because it not only helps to tenderize the onions but also infuses them with flavor. You’ll want to let them soak for at least 30 minutes. If you have the time, I recommend going even longer—up to an hour works wonders! Just pop them in a bowl, cover, and let them hang out while you prepare the rest. Trust me, this little step makes a huge difference in texture.

Preparing the Coating

While those onions are soaking, it’s time to prepare the coating! In a mixing bowl, combine 1 cup of all-purpose flour, 1 teaspoon each of garlic powder, onion powder, and paprika, along with a pinch of salt. Whisk it all together until well mixed. This mixture is where the magic happens, giving the onions that extra crunch and flavor. Feel free to tweak the spices to match your taste—if you like a bit more kick, throw in some cayenne pepper!

Preheating the Air Fryer

Now, let’s get the air fryer ready! Preheating is super important because it ensures even cooking and that delightful crunch. Set your air fryer to 350°F (175°C) and let it preheat for about 5 minutes. This little step means your onions will start cooking perfectly from the moment they hit the basket. You won’t want to skip this!

Cooking the Onions

Once your onions are soaked and your air fryer is preheated, it’s time to cook! Drain the onions from the buttermilk and coat them in the flour mixture. Make sure they get a good, even coating. Then, spray the air fryer basket with cooking spray to prevent sticking. Place the coated onions in a single layer in the basket—don’t overcrowd them, or they won’t crisp up as nicely. Give them a light spray of cooking spray on top, too. Now, cook them for about 10-15 minutes, shaking the basket halfway through to ensure they cook evenly. Keep an eye on them; you want that beautiful golden brown color! When they’re crispy and ready, carefully remove them, and let that delicious aroma fill your kitchen. You’re going to love this!

Tips for Success

Now that you’re ready to whip up those air fryer crispy fried onions, let me share some of my top tips to ensure they turn out perfectly every time! Trust me, these little nuggets of wisdom will save you from common pitfalls and help you achieve that crunchy perfection.

First up, make sure your onions are sliced evenly. If they’re too thick, they won’t crisp up nicely. I like to use a sharp knife or a mandoline for consistent slices. This way, every piece cooks uniformly, giving you that satisfying crunch.

Next, don’t rush the soaking process! Remember, at least 30 minutes in the buttermilk does wonders for flavor and texture. If you can spare the time, an hour is even better. Just let them soak while you prep other ingredients or clean up the kitchen.

When it comes to the flour mixture, feel free to play around with the spices. If you want to experiment, add some smoked paprika for a deeper flavor or even a sprinkle of Parmesan cheese for an extra savory kick. Just be careful not to overdo it—balance is key!

Lastly, keep an eye on the cooking time. Every air fryer is a bit different, so start checking around the 8-minute mark. You want that perfect golden brown color, and if they’re not there yet, just give them a little more time. Remember, it’s all about listening to your food!

Follow these tips, and you’ll be the proud chef of the crispiest fried onions around. Enjoy the process and happy cooking!

Variations

One of the best things about air fryer crispy fried onions is how versatile they are! You can easily switch things up to match your mood or the dish you’re making. Here are some fun variations to try:

Spicy Kick: If you love heat, add a teaspoon of cayenne pepper or chili powder to the flour mixture. It’ll give your crispy onions a delightful kick that pairs perfectly with burgers or spicy dishes.
Herb Infusion: Fresh or dried herbs can elevate the flavor! Consider adding a teaspoon of dried thyme, rosemary, or even Italian seasoning to the flour for an aromatic twist that’s fantastic on roasted veggies or salads.
Cheesy Goodness: For a cheesy upgrade, mix in a tablespoon of grated Parmesan cheese into the flour mixture. This adds a savory depth that’s just irresistible. It’s perfect for topping creamy casseroles!
Sweet and Savory: Try adding a drizzle of honey or maple syrup to the onions right before the cooking process for a sweet glaze that contrasts beautifully with the crispy texture. This works wonders on roasted sweet potatoes or in a salad with fruits.
Seasoned Panko: For an extra crunch, substitute half of the flour with panko breadcrumbs. This will give you an even crunchier texture that’s perfect for those who crave a hearty bite!

Feel free to experiment with different combinations to find your perfect flavor. The beauty of cooking is in the creativity, so don’t be afraid to have fun with these variations! You’ll discover new favorite flavors that will make your air fryer crispy fried onions even more enjoyable.

Storage & Reheating Instructions

Now, if you happen to have any leftovers of those delicious air fryer crispy fried onions (though I doubt it!), storing them properly is key to keeping that crunch intact. Here’s how I do it:

First, let the crispy onions cool completely before storing them. This helps reduce moisture, so they don’t get soggy. Once cooled, transfer them to an airtight container. I like to use a glass jar or a resealable plastic bag—just make sure it’s sealed tightly! You can keep them in the fridge for up to a week, but trust me, they’re best enjoyed fresh.

When it comes to reheating, the air fryer is your best friend! Preheat your air fryer to around 350°F (175°C) and give the onions a quick 3-5 minute warm-up. This will bring back that crispy texture. If you don’t have an air fryer handy, you can pop them in a conventional oven at the same temperature for a few minutes, just keep an eye on them so they don’t burn.

Whatever you do, avoid using the microwave! It may seem convenient, but it’ll turn those crunchy delights into a chewy mess. So, stick to the air fryer or oven for the best results. Enjoy every crispy bite!
