Roast potatoes with rosemary

Whenever my family has a roast leg of lamb for dinner, it almost seems natural to have roast potatoes to accompany it. Roast potatoes are one of those side dishes that are the perfect accompaniment for any roast.  However, roast potatoes can either be really good or just mediocre. The key to perfect roast potatoes is to have the inside of the potato be fluffy while having the exterior of the potato be crisp.

I learned how to make these perfect roast potatoes in South Africa from a family friend who also taught me how to make Indian roti and curry. We had these roast potatoes, cooked this way, every Saturday without fail.

Tips for making perfect roast potatoes.

Types of potatoes.

For these particular roast potatoes, I prefer to use Yukon Gold or other non-baking potatoes.  I feel that the russet or baking potatoes do not hold up during the cooking and roasting process and is therefore more difficult to handle.

Parboiling the potatoes.

This is key to getting the crispy exterior. Par boiling is literally partial boiling.  The potatoes are only partially cooked.  By partially cooking the potatoes, the cooking process breaks down the starches of the potato, allowing it to caramelize easier as well as take a lot less time to cook.  Add the potatoes to the cold, salted water to ensure even cooking throughout the potato.

Salt.

Adding a generous amount of salt during the boiling process and a little during roasting is key to adding flavor.

Cool potatoes.

Cooling the cooked potatoes after parboiling allows the potatoes to firm up so they are easier to handle when preparing them for roasting.

Roasting.

I usually roast my cooked potatoes on a piece of foil on a baking tray with a generous amount of olive oil.  The olive oil prevents the potatoes from sticking.  Shake your potatoes on the tray to ensure that the bottoms of the potatoes are oiled.

Turning the potatoes.

During roasting, the potatoes will have to be turned.  Turning each one individually with a pair of tongs does result in uniformly roasted potatoes.

Gas ovens.

If you have a gas oven and the roasting process is taking too long, place the pan on the base of the oven so it has direct contact with the oven floor.  However, make sure you check your potatoes frequently as the potatoes will brown quickly.

Leftovers.

For the longest time, we used to encourage everyone to "finish the potatoes" because it never tasted good as leftovers.  Recently, I found a wonderful way to repurpose leftover roast potatoes.  They were so good that I was requested to make roast potatoes again just to have these smashed potatoes!
