🧅 Air-Fried Savory French Onion Tartlets 🇫🇷

An incredible, high-impact lunch that captures the rich, deeply savory essence of classic French onion soup in a convenient, handheld form. By utilizing a light, flaky puff pastry square as the vehicle and loading it with slow-jammed, caramelized onions and a mountain of nutty Gruyère cheese, you create a magnificent flavor profile. The high-velocity convection air instantly lifts the pastry layers into a towering, shattered crunch while melting the cheese into a bubbling, localized brown crust.
