Air Fryer Roasted Chestnuts
Air fryer chestnuts are a quick and practical way to enjoy this quintessential autumn snack. They come out perfectly roasted with crispy shells and soft, sweet interiors.

📖 The Story
In Portugal, roasted chestnuts are a deeply rooted tradition tied to Saint Martin's Day celebrations on November 11th. On this day, Portuguese people gather to eat roasted chestnuts and drink água-pé (young wine) or jeropiga (sweet fortified wine), celebrating the end of the grape harvest. Street vendors known as 'castanheiras' are iconic figures in Portuguese autumn streets, with their steaming carts roasting chestnuts over hot coals. The air fryer offers a modern and practical alternative to recreate this traditional flavor at home.
