Why Is My Potato Bake So Runny?
There are several reasons why your potato bake may be runny. It could be due to overcooking the potatoes, using too much cream or milk, not allowing enough time for the dish to set after baking, or not using enough cheese or other thickeners. It may also be helpful to use a starchy potato variety like Russet or Yukon Gold, and to sprinkle the top of the bake with breadcrumbs or cornflakes to absorb excess liquid.
