I think we’ve established I love a galette. What’s better than a galette, a galette with my two other great loves cheese and mushrooms.
This is definately a pure filth recipe, yes it’s rich but it’s not the type of thing you’re going to make every day.
When cooking for vegetarians I often feel bad that the main course can look a bit lacklustre. This looks good when you bring it to the table and tastes amazing.
If you are making this, it’s really important that the filling is totally cold before you assemble the galette (otherwise you’ll end up with pastry that will melt and be impossible to handle).
The good thing is that if you are making this for a special occasion you can prepare all the elements in advance and assemble the elements just before baking.
For the pastry
200 Grams Plain flour
100 Grams Butter
1 Egg yolk
1/2 Tsp Salt
1/2 Tsp Cayenne pepper (optional)
Additional egg yolk to brush the galette with before baking
For the filling
500 Grams Mushrooms (sliced)
25 Grams Butter
1 Tbsp Olive oil
Salt and pepper
25 Grams Grated cheese
25 Grams Butter
25 Grams Plain flour
25 Grams Grated cheese (I used Cheddar but you can use other cheeses)
To make the pastry, and the flour, butter, salt, egg yolk and Cayenne to a food processor and whizz until the mix resembles breadcrumbs
Gradually add some small amounts of very cold water until the mix starts to come together
Turn the mix onto a floured surface and form into a ball before wrapping in cling film and chilling for at least 30 minutes
For the cheese filling, melt the butter over an even heat and stir in the flour to create a soft paste
Add the milk and stir continuously until the paste in combined and the sauce starts to thicken.
Cook over a low heat stirring regularly for another 10 minutes until the sauce no longer tastes floury. Stir in the cheese, once it has melted remove from the heat and place a sheet of cling film on the surface to stop a skin forming
In a large frying pan’ heat the oil and butter together, and half the mushrooms (if you add all the mushrooms in one go they steam not fry). One of the best pieces of advice I ever received from a chef is not to stir mushrooms too often, as it makes them release water which makes them soggy. So fry for 5 minutes each side without stirring too much, set to one side and allow to cool
Roll out the pastry on a floured surface in a circle that is about 1cm thick. Transfer to a sheet of baking paper and place on a baking sheet
Spread the thick cheese sauce in the centre of the pastry leaving a 3-4cm border around the edge of the pastry
Place the fried mushrooms on top of the cheese sauce. Brush edges of the pastry with the remaining egg yolk and pleating the edges inward
Brush the outside of the galette with egg yolk and sprinkle grated cheese over the top of the mushrooms
