Fill a large pot with cold water and bring to a boil.

Add the potatoes and cook for 30-45 minutes at medium heat, or until soft.

Drain the potatoes and place back into the cooking pot. Cover.

Using all of your might, shake the pot really hard until the potatoes begin to break apart and become floury.

Add the garlic, rosemary, and salt and fold together with the potatoes using a large spoon. Don’t mix vigorously or the whole thing will get gluey.

Heat the BBQ to high or, your oven to 450F.

Pour the olive oil into an oven safe dish and place the dish into the BBQ or oven until the oil is very very hot. DO NOT BURN YOURSELF!!! The dish from this moment on is going to be blazing hot so don’t touch it and make sure you have proper oven mitts to lift and carry it. My husband The Critic got sooooooo excited to taste these potatoes that he accidentally touched the boiling hot dish trying to get some of the potatoes onto his plate. Ouch! Happy Father's Day, here's a burned hand! Poor Critic.

When the oil is hot, add the potato mixture to the dish. Using a large spoon, toss the potatoes in the oil to ensure that they all come into contact with it.

Place the dish back into the BBQ/oven for 30-45 minutes, tossing the potatoes every 10 minutes or so, until they’re browned and crispy.
