How to Prepare Air Fryer Fried Onions

Alright, let’s get into the nitty-gritty of preparing these scrumptious air fryer fried onions! Follow these steps, and you’ll have the crispiest, tastiest onions in no time!

Step-by-Step Instructions

Soak the Onions: Start by thinly slicing your two large onions. Trust me, the thinner the slices, the crispier they’ll be! Once sliced, place them in a bowl and pour in 1 cup of buttermilk. Make sure the onions are fully submerged. Let them soak for at least 30 minutes. This soaking process not only adds flavor but also helps the coating stick better.
Mix the Coating: While those onions are soaking, let’s prepare the coating! In a separate bowl, mix together 1 cup of packed all-purpose flour, 1 teaspoon of garlic powder, 1 teaspoon of paprika, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. You want to ensure the spices are evenly distributed in the flour. This blend will give your onions an amazing flavor boost.
Coat the Onions: After the onions have soaked, take them out of the buttermilk and let any excess drip off. Now, toss them into the flour mixture, making sure every slice is well-coated. Don’t be shy—get your hands in there! You want that flour to cling to the onions for that beautiful crunch.
Preheat Your Air Fryer: Preheat your air fryer to 375°F (190°C). This step is crucial because it ensures that the onions start cooking immediately, helping them achieve that golden-brown color we all love.
Cook the Onions: Once the air fryer is preheated, place the coated onions in the basket in a single layer. It’s important not to overcrowd them; otherwise, they won’t crisp up as well. Drizzle with 1 tablespoon of olive oil for that extra crunch and flavor. Cook them for about 10-12 minutes, shaking the basket halfway through to ensure even cooking. You’ll want to keep an eye on them—every air fryer is a bit different, so adjust time as needed based on your desired crispiness.
Cool and Serve: Once they’re a lovely golden brown, carefully remove the onions from the air fryer and let them cool on a wire rack. This cooling step is key, as it helps them stay crispy! After a few minutes, they’re ready to be served on whatever dish you desire!

And there you have it! Follow these steps, and you’ll be the proud maker of the crispiest air fryer fried onions around. Just remember to savor the moment when you take that first bite—deliciousness awaits!

Tips for Success with Air Fryer Fried Onions

To ensure your air fryer fried onions turn out perfectly crispy, here are some handy tips to keep in mind:

Soak Longer for Extra Flavor: If you have the time, soaking the onions in buttermilk for an hour or even longer can enhance the flavor and tenderness. It’s worth the wait!
Adjust Cooking Time: Keep an eye on your onions as they cook. If you like them extra crispy, you can add a couple of minutes to the cooking time. Just remember to shake the basket halfway through to promote even browning.
Don’t Overcrowd the Basket: For the best results, cook the onions in batches if necessary. Overcrowding can lead to uneven cooking, preventing that delightful crispiness you’re after.
Storage Tips: If you have any leftovers (though I doubt you will!), store them in an airtight container at room temperature. They’ll stay crispy for a day or two, but I recommend enjoying them fresh for the best taste!

With these tips, you’ll be well on your way to mastering the art of air fryer fried onions. Happy cooking!

Can I use other types of onions?

Absolutely! While I love using yellow onions for their sweetness and crunch, you can experiment with other varieties as well.

Just a heads up, they’ll stay crispier that way! If you need to keep them longer, you can pop them in the fridge, but they might lose some of that delightful crunch.
