How to Soffritto Lento

What You Need to Know

The soffritto lento technique relies on the Maillard reaction (120-180°C) and caramelization (160-180°C) to transform cellulose-rich vegetables into flavor precursors. Onions release thiosulfinates that decompose into sweeter compounds, while celery's apigenin glycosides undergo thermal degradation into bitter phenolics that balance the sweetness.

Forms the flavor backbone for ragù alla Bolognese, minestrone, and risotto Milanese. The extended cooking allows volatile aromatics to polymerize into stable flavor compounds that withstand prolonged simmering.
