How to grill potatoes and sweet potatoes on the barbecue

Potatoes are one of the most common garnishes in a good barbecue. But what kind of potatoes are the best for grilling? And how to do it? Keep reading to learn how to grill potatoes (and sweet potatoes) on the grill and serve it deliciously at your next BBQ party.

The best potatoes for grilling

The first step to roast potatoes on the barbecue is choosing the type of potato we will use. The ideal potato varieties for grilling are red skin and yellow flesh, which, being somewhat more floury, roast better.

The size will determine the cooking time of the potato. As a guide, a small potato, smaller than an egg, for example, will need about half an hour to roast, while larger potatoes may take up to 50 minutes to be done.

In any case, a kitchen trick to know when it is ready is to press on the central part of the potato with a fork or tongs.

Tips and tricks for grilling potatoes or sweet potatoes

To roast potatoes on the grill, you have to wash them well to remove any remaining dirt or impurity from the skin since they will be roasted without peeling them first.

Then, you should dry them and wrap them tightly in aluminium foil. This works as a conductor of heat while protecting the skin to not burning on the outside. Once covered in aluminium, we have two options for roasting the potatoes. One is to put them on the grill. The other is to bury them in the embers. In both cases, the cooking times still depend on the size of the potato.

This way of roasting potatoes on the grill is also applicable to sweet potatoes. In case you are wondering, although the sweet potato is called “a potato”, it does not belong to the same botanical family as potatoes. However, due to its sweetness, the sweet potato is an ideal garnish for pork and beef because of the contrast of flavours it offers. We love this combination so much!
