Preheat oven to 200 degrees celsius (390 degrees fahrenheit).
Grease baking dish or spray with oil.
Peel potatoes and onion and slice thinly.
Drain salmon and remove large bones and skin. Mash with a fork.
Whisk together cream, milk, lemon juice, mustard and Worcestershire sauce. Set aside.
Arrange about ⅓ of the potato slices on the bottom of the baking dish.
Arrange about ⅓ of the onion on top of the potatoes as the next layer.
Arrange about ⅓ of the salmon on top of the onion as the next layer.
Sprinkle about ⅓ of the cheese as the next layer.
Pour ⅓ of the wet mixture over the layers and add a little dill and salt and pepper.
Repeat these steps two more times, but adding the cheese and onion as the final top layer (that is, add wet mixture before these ingredients for the last layer).
Cover with a lid or foil and bake for 30 minutes.
Reduce temperature to 180 degrees celsius (360 degrees fahrenheit). Uncover and bake for another 45 minutes.
Notes
How long will it keep? It will last about 2-3 days in the fridge, so it's perfect for making up in advance the day before you're planning to serve it.
Can I freeze Salmon Potato Bake? I prefer not to.
What is the best way to re-heat this dish? It can be re-heated in the microwave (on low-medium power) or covered in the oven at 160 degrees celsius for half an hour.
