- 250g plain flour, sifted
- 300ml whole milk
- 2 eggs
- 2 tablespoons melted unsalted butter
- 2 tablespoons vegetable oil
- 50g Parmesan cheese, grated
- 75g unsalted butter
- 2 banana shallots, peeled and finely chopped
- 1 garlic clove, peeled and finely chopped
- 1kg button mushrooms, finely chopped
- 2 teaspoons finely chopped thyme leaves
- 2 teaspoons finely chopped flat-leaf parsley
- 400ml whole milk
- 1 bay leaf
- 8 black peppercorns
- ½ onion, peeled
- 40g unsalted butter
- 20g plain flour, sifted
- ½ teaspoon cayenne pepper
- ½ teaspoon freshly grated nutmeg
- 500g baby spinach leaves
- 1 tablespoon extra virgin olive oil
- Preheat the oven to 200°C/fan 180°C/gas 6.
- To make the crêpes, sieve the flour into a large bowl and gradually mix in the milk, 300ml of water, eggs and butter, then whisk until smooth.
- Heat a medium-sized non-stick frying pan over a medium heat. Once the pan is hot, add a little of the vegetable oil. Then pour in a ladleful of the crêpe batter and swirl the pan to spread out the batter and form a thin crêpe. Cook for 2 minutes, flip the crêpe over using a spatula, fish slice or palette knife and cook for a further minute on the other side. Slide the crêpe out of the pan on to a plate to one side and place a sheet of kitchen paper on top to stop the crêpes from sticking together. Repeat with the rest of the batter, one ladleful at a time and adding a little more oil to the pan between cooking each crêpe, until you end up with a pile of 8 cooked crêpes interleaved with sheets of kitchen paper.
- To make the mushroom filling, place the butter in a medium-sized sauté pan over a medium heat. Once the butter has melted, add the shallots and cook for 2 minutes until they are soft, then add the garlic, mushrooms and thyme and cook for a further 8–10 minutes, until the moisture from the mushrooms has evaporated. Remove the pan from the heat, season with salt and pepper and sprinkle on the chopped parsley. Set aside.
- To make the béchamel sauce, place the milk, bay leaf, peppercorns and onion in a medium-sized saucepan and warm over a low heat but do not let the milk boil. In a separate medium-sized saucepan, melt the butter over a medium heat then add the flour to make a roux. Cook, stirring, for 2–3 minutes.
- Strain the warmed milk, discarding the aromatics, and gradually pour the milk into the roux, whisking all the time. Cook for a further 5 minutes until you have a smooth, thickened béchamel sauce, then season with salt, cayenne pepper and nutmeg. Take 2 tablespoons of the sauce and mix into the mushroom filling to bind that together.
- On a clean work surface, lay 2 crêpes overlapping one another to give a large surface area and spread a quarter of the mushroom filling evenly over the crêpes. Taking the end nearest to you, roll up into a Swiss roll shape. Cut the roll into 2cm-thick pieces. Repeat with the remaining 6 crêpes and the rest of the filling.
- Heat a medium-sized frying pan over a low to medium heat, throw in the baby spinach and drizzle over the extra virgin olive oil. Cook for 2 minutes until the spinach leaves have wilted.
- Place the wilted spinach in the bottom of 4 x 5 inch/13cm round or oval individual gratin dishes, or use one large dish. Pour a little béchamel sauce over the top and then place a quarter of the slices of filled crêpe roll on top, overlapping the slices slightly. Pour the remaining béchamel sauce over the top and sprinkle on the grated Parmesan.
- Place the 4 gratin dishes on a baking tray and put in the preheated oven for 8–10 minutes until the gratins are golden brown on top.
