Polenta con Luganiga e Fontina al Forno Valdostana

Overview

A baked polenta gratin from the Aosta Valley — firm polenta sliced and layered with slices of luganiga sausage and Fontina DOP in a buttered baking dish, topped with more Fontina and baked until the cheese melts and the top caramelises to a golden crust. A winter staple that uses leftover polenta from the previous day.

Flavour Context

Deeply savoury, porky and milky; the polenta's cornmeal sweetness contrasts with the tangy Fontina melt; the sausage adds spice and fat; the golden crust is the prize — winter food of the mountain kitchen

Key Principles

{"Cook the polenta the day before — freshly made polenta is too soft to slice; chilled polenta firms and slices cleanly","Slice polenta at 1.5–2cm — too thin and it breaks during layering; too thick and it doesn't heat through before the cheese browns","Pre-cook the luganiga slices in a dry pan until lightly coloured before layering — this renders excess fat and prevents the bake from being greasy","Use Fontina DOP in generous quantity — at least 80g per serving; the melted cheese is the sauce of this dish","Bake at 200°C until the top is deeply golden — the cheese should be bubbling and browned, not merely melted"}

Pro Tips

{"Brush the baking dish with mountain butter generously — the butter crisps the edges of the polenta into a crackling border","A small amount of truffle shaved between the layers is the celebratory version served at Valle d'Aosta festivals","Polenta at a coarser grind (bramata) gives more textural contrast against the silky cheese — worth seeking out"}

Common Mistakes

{"Using freshly made polenta — it smears rather than slicing and layers collapse in the oven","Not pre-cooking the sausage — raw sausage in the bake releases too much fat and makes the dish greasy","Under-baking — pale, barely melted Fontina lacks the nutty, caramelised quality that makes the dish"}
