To prepare the tart, melt the butter in a frying pan on the stove-top over high heat. Add the sliced mushrooms and cook until golden (and all of the liquid has evaporated).
Add the thyme and garlic and stir until fragrant.Pour the mixture into the base of the prepared pastry shell.
Place small dollops of goats cheese and caramelised onion on top of the mushroom mixture.
Add the eggs and cream to a bowl and whisk until well combined.
Pour the egg mixture into the store-bought pastry shell or blind-baked pastry shell and bake for 35 minutes or until golden and cooked through.
