Step‑by‑Step Instructions for Air Fryer Crispy Onions

Step 1: Preheat Air Fryer
Begin by preheating your air fryer to 350°F (175°C). This crucial step ensures that your Air Fryer Crispy Onions will cook evenly and develop that perfect crunchy texture. Allow the air fryer to heat for about 5 minutes, and you’ll start hearing a gentle hum as it gets ready to work its magic.

Step 2: Slice Onions
Thinly slice your onions using a mandolin or a sharp knife for uniformity. Aim for about 1/8 inch thickness, as thicker slices will not crisp properly. The key to achieving the ideal crunch in your Air Fryer Crispy Onions lies in their size; even slices will ensure they all cook at the same rate. Place the sliced onions in a mixing bowl.

Step 3: Toss with Oil and Seasoning
Drizzle a light coating of oil over the sliced onions and toss them well to ensure even coverage. Then, sprinkle your chosen seasonings, such as salt, garlic powder, or paprika, over the onions. Make sure each slice is well-coated, as this not only bolsters flavor but also helps achieve that sought-after crispiness during cooking.

Step 4: Arrange in Air Fryer
Carefully lay the seasoned onions in a single layer in the air fryer basket. Avoid overcrowding, as this can lead to uneven cooking and soggy onions. Ensure each piece has some space around it for optimal airflow, which is essential for those irresistibly crispy results in your Air Fryer Crispy Onions.

Step 5: Air Fry
Set the air fryer to cook for 18–30 minutes, shaking or stirring the onions every 4–5 minutes to promote even browning. As they cook, keep an eye on them; you want a delightful golden-brown color and a satisfying crunch. Cooking time may vary, so check for that perfect crispiness as you approach the 20-minute mark.

Step 6: Cool Before Storing
Once cooked to perfection, carefully remove the crispy onions from the air fryer and transfer them to a cooling rack or plate. Allow them to cool completely, as this helps maintain their crunchiness. Ensure your Air Fryer Crispy Onions are at room temperature before storing them in an airtight container to keep them fresh for days.
