Spread thecrème fraiche over the base and sprinkle over the sliced onions.
Add the cooked bacon and sprinkle over the cheese.
Bake at 230C/450F/Gas 8 for 10-15 minutes.

Notes
Hints and Tips:
Make sure that you use full fat products for this recipe. Lower fat versions tend to separate when they get hot and make the pastry soggy.
Roll the dough directly onto the silicone liner or onto baking parchment. This makes it easier to transfer to the baking sheet. After cooking it's then easier to slide onto a board for presentation and cutting.
