Pretty good recipe. I didnt have Swede, so replaced with an equal weight of veggie sausages, extra mushrooms and carrots. Prep time is fairly long. The thin slices of potato on top also take a while and don't add that much taste to the dish, so next time I'd probably just replace that with mash or Puff pastry. Be sure to season the mushroom mixture with salt and pepper before baking, otherwise it's a little bland. But the end result was tasty!
