Instructions
Preheat oven to 350°F (180°C/Gas 4)
Your pastry shell should be just cooked but still pale in colour.
Melt the butter in a heavy based pan and cook the onions gently until they are just cooked and golden brown in colour.
Stir in the thyme leaves and leave to cool.
Whisk the eggs lightly then whisk in the cream.
Add the cheese and the salt and pepper to taste.
Fill the pastry shell with the onions.
Pour the egg and cream mixture over the onions.
Bake for about 30-45 minutes or until golden brown and the egg mixture has puffed up. Smells and tastes yummy!
