Preheat oven to 450°F and add salt to a large lipped baking dish, I usually use a 9x13-inch baking pan. Make sure salt is evenly spread over the surface.
Add the potatoes to the salt, nestling them into it.
Slice the top of the bulb of garlic off and place it cut side up in the pan.
Add herbs around the potatoes.
Brush the potatoes all over the exposed skin with canola oil.
Cover with aluminum foil and bake for 1 hour. Remove aluminum foil and herbs and set the garlic to the side, then brush the potatoes with the remaining oil and bake for an additional 15 minutes.
