Crispy Fried Shallots

Set a fine-mesh strainer over a medium heatproof bowl. Thinly slice shallots crosswise into rings on a mandoline (they should be about the thickness of a dime).

Place shallots in a medium saucepan and pour in oil to submerge. Set over medium-low heat and cook, stirring often with a fork to encourage rings to separate, until shallots are golden brown, 20–25 minutes. (Keep an eye on them; once they start to brown they’ll darken fast).

Pour shallots into strainer to drain, then transfer to paper towels. Season with salt and let cool. Reserve shallot oil for another use.

Do Ahead: Shallots can be fried 5 days ahead. Store airtight at room temperature.
