Method
Boil & Mash Potatoes (25 mins, do ahead)
- Start the potatoes going. Chuck peeled, even-sized potato chunks into a big saucepan of cold salted water. Bring to a boil, then simmer 15-20 mins till totally tender—fork slides in easy. Drain well, steam dry in the pan with the lid on for a few mins.
- Rice ’em smooth. Push hot potatoes through a ricer into a bowl. Gentle now—keeps them fluffy for that taleggio pommes duchesse magic.
- Mix in riches. Fold through butter, whisked egg yolks, grated taleggio, and Dijon if you fancy that kick. Splash in milk till creamy. Season generously. Bag it up with the star nozzle and chill while filling cooks—pipes like a dream later.
Build the Filling (30 mins, overlaps with mash)
- Sweat the veg base. Heat oil in a large pan, tip in onion, garlic, celery, carrots and a pinch salt. Fry 5-10 mins till softened—don’t rush, builds sweet foundations for mushroom cottage pie.
- Mushrooms next. Add chopped chestnut mushrooms, cook 5 mins till they shrink and release juices. Smells forest-fresh already.
- Tomato boost. Stir in tomato purée, cook 2 mins to caramelise—deepens everything.
Simmer & Reduce (20 mins)
- Herbs and wine. Toss in thyme leaves, bay leaf. Pour red wine, simmer till halved—concentrates flavours for rich mushroom cottage pie gravy.
- Finish the filling. Add drained lentils, mushroom stock, Henderson’s relish, gravy granules. Bubble 10-15 mins till thickened. Taste—savoury heaven. Preheat oven to 220°C/200°C fan/gas 7 now.
Assemble & Bake (30 mins)
- Layer up. Pour hot filling into baking dish. Pipe mash swirls over top—or spoon and wave with a hot spoon for rustic vibes.
- Bake golden. Oven 25-30 mins till piping hot and mash crisps brown. Rest 5 mins—gravy sets perfect.
Serve with steamed Tenderstem broccoli. Broccoli cuts the richness just right.
