Onion Galette
2 tbsp unsalted butter
3 onions, thinly sliced
3 oz Gruyere cheese, grated
2 or three sprigs of thyme
1 egg white
short crust pastry
1. In a large skillet heat the butter until the foam subsides. Add the onions and stir to coat. Cooking over a medium-low heat, stirring occasionally until caramelized. This could take 30 to 40 minutes. Reduce heat if the onions are browning too quickly.
2. Roll out the pasty until it is as thin as you desire. Place in a small pie plate. Sprinkle half of the cheese and half of the thyme over the centre of the pastry. Once the onions are ready, spread them out over top of the cheese. Add the rest of the cheese and thyme.
3. Carefully fold the edges of the pastry up so it partially covers the filling. Brush with egg white. Bake at 375F for about 30 minutes or until the pastry is golden brown. Remove from oven and allow the galette to rest for 5 or so minutes.
