Air Fry: Spread the peanuts in a single layer in your Air Fryer basket.
The Sweet Spot: Roast at 320°F for 11–12 minutes.
The Shake: At the 6-minute mark, give the basket a good shake to ensure an even, golden tan on all sides.
Cool Down: Transfer immediately to a flat plate. Crucial: Let them cool completely (about 15 minutes) to reach maximum crunch.
The Smash: Place cooled peanuts in a mortar and pestle or a silicone bag. Lightly hit them with a kitchen mallet to create rustic, irregular pieces.
Notes
The "Carry-Over" Rule: Peanuts keep cooking for a few minutes after the timer hits zero. Take them out when they look pale-gold; they will darken to a perfect amber as they cool.
Modern Mom Hack: Growing up in HCMC, we used a wok and salt, but the Air Fryer in Mississauga is my secret weapon for that same nostalgic "street food" aroma with zero effort.
Texture Architecture: Don't use a blender! The "mallet-smash" creates different sized crunches that hold onto your dipping sauce much better.
Storage: Keep in an airtight jar at room temperature for up to 2 weeks.
