These low-carb, air fryer crispy fried onions deliver maximum crunch without the need for heavy batters or deep frying. Utilizing thin curls of fresh onions and a minimal amount of oil, this quick recipe produces a versatile staple that works beautifully as a savory snack or a crispy topping for casseroles, burgers, and salads.
Ingredients
Produce: 2 large yellow or sweet onions
Cooking Fat: 1 tbsp olive oil or avocado oil
Seasoning: 1/2 tsp garlic powder, 1/2 tsp salt, 1/4 tsp black pepper
Instructions
Step 1: Slice the Onions
Peel the onions and cut them into very thin, uniform rings or semi-circles using a sharp knife or a mandoline slicer. Separate the rings completely so they cook evenly.
Step 2: Season and Coat
Place the sliced onions into a large bowl. Drizzle with the olive or avocado oil, then sprinkle with the garlic powder, salt, and black pepper. Toss thoroughly with your hands to ensure every onion strand is lightly coated in oil and spices.
Step 3: Preheat the Air Fryer
Preheat your air fryer to 350°F (175°C) for 3 minutes before adding the ingredients.
Step 4: Air Fry in Batches
Place the seasoned onions into the air fryer basket. To ensure a uniform crunch, avoid overfilling the basket; work in two separate batches if necessary.
Step 5: Shake and Monitor
Cook for 15 to 20 minutes total. Every 4 to 5 minutes, pull out the basket and shake it vigorously, or use tongs to toss the onions. This redistributes the moisture and ensures the edges do not burn while the center crisps. Watch closely during the final 3 minutes as they transition quickly from golden to dark brown.
Step 6: Cool and Serve
Remove the onions from the air fryer and spread them out in a single layer on a plate lined with paper towels. They will continue to crisp up substantially as they cool. Serve immediately as a standalone snack or as a textured topping, matching the deeply golden, tangled pile shown in image_12.png.
