Air frying vegetables without oil offers clear benefits:

Step-by-Step Guide: Crispy Air Fryer Vegetables Without Oil

Step 1: Wash and Dry Thoroughly

Moisture is the enemy of crispiness.
Pat vegetables completely dry using a kitchen towel.

Step 2: Cut Evenly

Uniform size = even cooking.
Thin slices or small florets work best.

Step 3: Season Smart (No Oil Needed)

Use dry seasonings:

• Garlic powder
  
• Paprika
  
• Black pepper
  
• Onion powder
  
• Nutritional yeast (adds umami)
  

Salt after cooking to avoid drawing out moisture.

Step 4: Preheat the Air Fryer

Preheat to 375°F (190°C) for 3–5 minutes.

Step 5: Cook in a Single Layer

Avoid overcrowding.
Air circulation creates crispiness.

Step 6: Shake or Flip Midway

Shake the basket halfway for even browning.

Step 7: Final Crisp Boost

Increase the temperature to 400°F (205°C) for the last 2–3 minutes.

Common Mistakes Beginners Make

• Overcrowding the Basket: Too many vegetables = steaming instead of crisping.
• Skipping Drying: Even a little moisture reduces crunch.
• Using Wet Marinades: Sauces prevent crisping. Add after cooking instead.
• Salting Too Early: Salt pulls out water and softens vegetables.

Texture Tips for Extra Crisp (Without Oil)

• Use perforated parchment liners
  
• Cook in smaller batches
  
• Add a pinch of cornstarch to dry vegetables
  
• Finish with high heat
