Introduction

Somewhere between a tartiflette and a dauphinoise, this rich gratin takes elements from both and combines them for a very satisfying, if calorific, winter dish. (I have been known to have leftovers for breakfast.) If you can’t find a reblochon, substitute Gruyère and layer it in between the gratin as well. Serve with a green salad.

Ingredients

1kg	Maris Piper potatoes, sliced paper thin
1	onion, finely sliced
300g	chestnut mushrooms, thinly sliced
	sea salt
	freshly ground black pepper
	fresh nutmeg
2	cloves of garlic, grated
800ml	double cream
1 x 240g	reblochon cheese
10–12	fresh sage leaves
	To serve:
	green salad

Method

1. Preheat the oven to 180°C fan/200°C/ gas 6. Butter a medium-sized roasting tin or lasagne dish, then add a layer of potatoes, followed by onions and mushrooms. Season with a generous pinch of sea salt, black pepper and a grating of nutmeg, then repeat the layers, seasoning between each, finishing with a layer of potatoes.

2. Mix the garlic with the double cream, another good pinch of salt, pepper and grated nutmeg, then pour it all over the potatoes. Top with the reblochon, scatter over the sage leaves, then transfer to the oven and cook for 1 hour.

3. Let the gratin sit for 10 minutes, then serve with a crisp green salad alongside. Note: It might seem like you’re adding a lot of salt, but the potatoes absolutely drink it in: you may need to serve salt on the table so people can season to taste.
