For the salsify casserole, place the salsifies in boiling water for 5 minutes and then peel (this prevents the roots from “bleeding”).
Cut the salsify into small pieces, peel the potatoes and cut into small cubes. Mix the whipping cream with the eggs and add salt.
Spread the salsify, potatoes and diced bacon in a baking dish. Pour the cream-egg sauce on top and cover with Gouda.
Bake in the oven at 180 °C (top and bottom heat) for 30 minutes.
