Jura Mushroom Croûte

Jura Wine, Oven-Baked Bread

Croûte aux champignons is a dish from the French Jura and the wider Franche-Comté region, where thick slices of bread serve as the base for a warm topping. There are several versions: some use local cheese, while others put more emphasis on the mushrooms and a splash of wine. In this version, the ragout stays creamy without being heavy, and the toasted bread makes a sturdy, crisp base. That makes it more than a light starter: with two croûtes per person and a salad, it’s a complete meal.

Choose mushrooms with different textures. Chestnut mushrooms have a rich, earthy flavor; oyster mushrooms become nicely firm and lightly crisp around the edges. You can easily replace some with regular white mushrooms. Mushrooms are available all year round, but there’s often a wider selection of wild varieties in autumn. For this recipe, use only varieties you know well and that are suitable for cooking. Clean them with a brush or a slightly damp cloth, and cut large ones into similarly sized pieces.

A wide frying pan helps the mushrooms brown rather than stew. Cook them in batches if needed: if the pan is too crowded, they’ll release liquid and won’t brown as well. Let that liquid evaporate before adding the shallot. Dry white wine lifts the browned bits from the bottom of the pan and gives the cream sauce a little freshness. Vin Jaune is also used in the Jura; it has a distinctive, nutty flavor. A small splash is enough, and dry white wine is an accessible alternative.

The cream only lightly thickens the sauce. So let it reduce briefly, and stop as soon as it clings to the mushrooms; a thick sauce will quickly make the bread soggy. Country bread or sourdough with a firm crumb holds the topping well. Toast the bread first, then briefly put the topped slices under the grill so the topping gets hot while the crust stays crisp. Keep an eye on it, as bread can darken quickly under a hot grill.

Serve the croûtes straight away with lamb’s lettuce or another mild leafy salad, dressed with a simple vinaigrette. The fresh acidity cuts through the creamy ragout. A handful of grated Comté can be added over the mushrooms as a variation, but it isn’t necessary for this version. Cover any leftover ragout and refrigerate it within two hours; use it within two days. Reheat it in a pan and top freshly toasted bread just before serving. Store the salad separately.
