CHESTNUT, THYME & MUSHROOM CASSEROLE
6 steps
Prep:15minCook:35min
Chestnuts aren’t just for Christmas, they’re a great addition to vegetarian dishes all year round. Here we using their nutty sweetness with our chestnut mushrooms in a hearty casserole, with red wine and fresh thyme.
Riverford thoroughly recommend getting hold of a potato ricer, they make the smoothest mash with little effort, and aren't too expensive to buy. It's fine to use a potato masher, of course, but don't be too over zealous with it, as you can overwork the mash, making it gloopy.

After 8 minutes, add the garlic, thyme, mushrooms, cornflour and 1 tbsp of oil to the onion. Increase the heat slightly. Stir-fry for 2-3 minutes, to soften the mushrooms slightly.
