Instructions
Preheat the oven to 375 degrees Fahrenheit
Melt the butter in a large skillet on medium heat. Add in the onion and fennel, sprinkle with salt and leave to cook, stirring every few minutes for approximately 20 minutes until the fennel is tender and golden brown in color.
Add in the flour and stir to ensure it coats the fennel mixture and then add the cream and milk and stir. Cook for 5 minutes and then remove from the heat
To a large bowl add the potato slices (try to ensure they aren’t all stuck together). Season with salt and pepper and toss with your hands to ensure it’s all well coated.
Pour in the fennel mixture from the pan and add in 1 ½ cups grated cheese. Use tongs to toss to ensure it’s all well mixed together.
Pour the mixture into a greased baking dish, use a spatula to even it out on top and then sprinkle the remaining ½ cup gruyere cheese overtop.
Transfer to the oven to bake for 1 hour covered in tin foil and then remove the tin foil and cook for an additional 20 minutes until the cheese on top is golden and bubbly.
