- 1 Tablespoon oil
- 350 g (~ 3/4 lb) mushrooms, thinly sliced (I used a mixture of chestnut, baby portobello, and button)
- 1 teaspoon minced garlic
- 1/2 teaspoon dried thyme
- 1/2 teaspoon black pepper
- 1/4 teaspoon ground nutmeg
- 1/2 vegetable stock cube, crumbled
- 450 g (~ 1 lb) potatoes
- 1 Tablespoon butter
- 250 ml (~ 1 cup) cream (I used single cream)
- 200 g (~ 7 oz) brie, sliced
- Fresh parsley, to serve (optional)
Heat a dash of oil in a deep frying pan, and add the sliced mushrooms. Cook over a medium heat for around 5 minutes, stirring regularly, until fairly soft. Add the next 5 ingredients (garlic through stock cube), and cook for a few more minutes.
While the mushrooms are cooking, peel the potatoes and slice them very thinly. If you have a mandoline, you can use that - otherwise, just use a large knife.
Add the butter and cream to the pan with the mushrooms, and bring to a gentle simmer for a minute or two, until the butter has melted and the ingredients are well combined.
To assemble the mushroom gratin, layer up the creamy mushrooms with the sliced potatoes and the sliced brie. My baking dish measured approximately 8 x 8 inches. The exact order of your layers doesn't matter too much, but here's how I layered mine:- 1 or 2 tablespoons of cream spread around the bottom of the dish, to avoid sticking- 1/3 of the sliced potatoes- 1/2 of the creamy mushrooms- Another 1/3 of the potatoes- 1/2 of the brie- The final 1/3 of the potatoes- The remaining 1/2 of the creamy mushrooms- The remaining 1/2 of the brie Drizzle any remaining cream over the dish, trying to cover any potato edges that are exposed.
Cover the dish with a lid or some kitchen foil, and bake at 190°C (Gas Mark 5 / 375°F) for around an hour, or until the potato slices are completely soft. If you'd like to crisp up the topping a little, remove the lid, and return to the oven for a further 10 minutes, or until crisped up to your liking.
If you want to, garnish with fresh parsley before serving.
