Next, put all the foil-wrapped potatoes into a zip-lock plastic bag and store them in the freezer until needed.

What Type of Potatoes to Use for The Best Roast Potatoes

To make the best roast potatoes, use russet potatoes. They are not too starchy, which means they absorb moisture well and hold the shape you have cut them in. This makes them perfect for roasting. Russets also have a high sugar content, which helps them brown nicely when roasted.
