Parboiling is a method of cooking, wherein the food is only partially done. The degree of parboiling depends on the type of food and the specific recipe.

Usually, parboiling is recommended for denser vegetables like potatoes and carrots. Vegetables that are meant for canning and freezing, are parboiled to get rid of enzymes that cause their deterioration. Vegetables, like potatoes, carrots and cauliflower, take longer to cook. At the same time, there are vegetables that cook within a few minutes. Some recipes require both these types of vegetables to be cooked together. In that case, some of the vegetables remain half-cooked or overcooked. So as to avoid such problems, parboiling of the denser vegetables is recommended. Once done, they can be added to vegetables that take lesser time to cook. The partially done (parboiled) vegetables will get fully done, along with the other vegetables.

So, it is always better to parboil potatoes before roasting. Parboiling is also done to remove the skin of vegetables, like tomatoes.
