Chop the potatoes into small bite sized cubes.
In a large bowl, toss the potatoes and the oil.
Add the seasonings and toss again to coat evenly.
Spread onto 2 cookie sheets (the kind with a rim all the way around).
Bake at 450 degrees for at least 30 minutes, longer if you like them crispier. I like to switch the trays half way through to make sure they are crispy on both the top and bottom.
