Ingredients
Main Ingredients:
- 2 large onions (thinly sliced into rings or half-moons)
- 2 tablespoons cornflour (cornstarch)
- 2 tablespoons all-purpose flour (maida)
- 1 teaspoon salt (adjust to taste)
- 1 teaspoon paprika (optional for color and mild spice)
- ½ teaspoon black pepper
- ½ teaspoon garlic powder (optional for extra flavor)
- 1–2 teaspoons oil (for coating or spraying)
Optional Add-ons:
- ½ teaspoon chili powder (for spicy version)
- Pinch of sugar (helps caramelization)
- Rice flour (for extra crispiness)
Equipment Needed
- Air fryer (any standard model, 3–6L capacity)
- Mixing bowl
- Sharp knife or slicer
- Tongs or spatula
- Kitchen paper towel
- Mesh sieve or colander
Step-by-Step Instructions
Step 1: Slice the Onions
Peel the onions and slice them as thinly as possible. Thin slices are crucial because thicker slices will not crisp evenly in the air fryer. Aim for uniform cuts so they cook at the same rate.
Step 2: Separate the Layers
After slicing, gently separate the onion layers using your hands. This increases surface area and helps each piece become crispy instead of clumping together.
Step 3: Remove Excess Moisture
Place the sliced onions on a paper towel and pat them dry. Moisture is the enemy of crispiness, so this step is important for achieving a crunchy texture.
Step 4: Coat the Onions
In a mixing bowl, combine cornflour, all-purpose flour, salt, black pepper, and optional spices. Add the onions and toss well until each piece is lightly coated. The coating should be thin—not heavy or dough-like.
Step 5: Add Light Oil
Spray or drizzle 1–2 teaspoons of oil over the coated onions. Mix again so the oil lightly binds the flour coating. This helps achieve a fried texture in the air fryer.
Step 6: Preheat Air Fryer
Preheat your air fryer to 180°C (356°F) for 3–5 minutes. Preheating ensures even cooking and better crisping.
Step 7: First Air Fry Cycle
Spread the onions evenly in the air fryer basket. Do not overcrowd; cook in batches if necessary.
- Temperature: 180°C
- Time: 8–10 minutes
Shake or toss halfway through for even browning.
Step 8: Second Crisping Cycle
Increase temperature slightly to 190°C (374°F).
- Time: 4–8 minutes
Continue cooking until onions turn golden brown and crispy. Keep a close eye during the last 2–3 minutes to prevent burning.
Step 9: Cool Down
Remove onions from the air fryer and spread them on a plate or tray. They will continue to crisp as they cool. Avoid covering them while hot, as steam will soften them.
Texture Guide
- Light Crisp (Level 1): Slightly golden, soft center
- Medium Crisp (Level 2): Balanced crunch and softness
- High Crisp (Level 3): Fully crunchy, ideal for toppings
- Extra Crisp (Level 4): Deep golden, very crunchy, snack-style onions
For best results, aim for Level 3 or Level 4.
Pro Tips for Best Results
- Always slice onions evenly for uniform cooking.
- Do not overcrowd the air fryer basket.
- Shake the basket frequently to prevent sticking.
- A small amount of rice flour increases crunchiness.
- Use red onions for a sweeter flavor or white onions for sharper taste.
- Let onions cool fully before storing to maintain crispness.
Variations
1. Spicy Crispy Onions
Add extra chili powder or cayenne pepper for a spicy kick.
2. Sweet Caramel Crispy Onions

Storage Instructions
- Store in an airtight container.
- Keep at room temperature for up to 5 days.
- Avoid refrigeration as it softens crispiness.
- If they lose crunch, reheat in air fryer for 2–3 minutes at 180°C.
