Duck with Blackberry Sauce and Celeriac Mash
Duck breast with blackberry sauce and celeriac mash is an elegant French-inspired main course. The Thermomix steams the celeriac to fork-tenderness, blends it with butter into a velvety purée, and gently heats the blackberry sauce with sugar and water for a glossy, restaurant-style finish every time.
About this recipe
Duck with blackberry sauce and celeriac mash Thermomix TM7 brings classic French bistro cooking into your own kitchen with surprisingly little effort. Searching for an elegant duck recipe for your all-in-one kitchen machine often leads to complicated techniques, but here the TM7 does the heavy lifting: the celeriac steams gently in the Varoma while you sear the duck breasts, and the blackberry sauce is heated and blended to a glossy, sweet-tart finish in the same bowl. The result is a dinner-party worthy plate — crisp-skinned duck, sharp ruby sauce, and a velvety mash with a subtle nutty edge — that works brilliantly for a festive weekend dinner or an intimate autumn supper. Fresh blackberries are ideal in season, yet frozen berries work just as well, making this a recipe you can return to all year round.
Preparation tips
- Score the duck skin in a crosshatch pattern without cutting into the flesh, then pat it completely dry before searing; dry skin renders fat quickly and turns irresistibly crisp while the breast stays pink and juicy inside.
- Start the duck skin-side down in a cold pan and let the fat render slowly; pour off the excess duck fat and save it — it is wonderful for roasting potatoes later in the week.
- For an extra silky celeriac mash, pass the blended purée through a fine sieve before serving and fold in the butter at the end; a splash of the steaming liquid loosens it to the ideal consistency.
Recipe variations
- Lactose-free version: replace the unsalted butter in the celeriac mash with a good olive oil or a plant-based butter alternative; the blackberry sauce needs no dairy at all, so the entire plate becomes suitable for lactose-intolerant guests without losing its luxurious texture.
- Festive winter variation: swap half the blackberries for fresh figs or quartered plums and add a small strip of orange zest to the sauce; serve with the mash shaped in a ring mould for an elegant Christmas dinner presentation.
