Prepare the Shallots: Peel the shallots, rinse them, and pat them thoroughly dry with paper towels.
Slice the Shallots: Thinly slice the prepared shallots so they are ready for even air frying.
Coat with Oil: Place the sliced shallots in a bowl, add ½ teaspoon oil, and toss until the slices are lightly coated.
Preheat the Air Fryer: Preheat the air fryer to 250°F.
Arrange the Shallots: Spread the oiled shallot slices in a single layer in the air fryer basket.
Air Fry the Shallots: Cook the shallots for 15 to 20 minutes, shaking the basket about every 5 minutes to help them cook evenly.
Check for Doneness: Continue cooking until the shallots look golden brown and crispy, keeping in mind that the exact cooking time can vary depending on the air fryer.
Cool Completely: Remove the golden shallots from the air fryer and allow them to cool completely before using or storing.
