In a small bowl, stir together salt, pepper, paprika, and garlic powder. Cube potatoes into about 1/2-inch cubes. You can leave the skin on.
Bring a medium pot of salted water to a simmer. Add potatoes and boil until tender, about 6-8 minutes. Then drain potatoes.
Add oil to a large cast iron skillet (or heavy skillet) over medium heat. Add the drained potatoes and spread them out over the surface of the pan. Let sit for five minutes.
Stir potatoes once they are starting to crisp up a bit. Add half of the seasoning mix to the potatoes. Continue to let the potatoes cook over medium heat. Don’t over-stir them. Let them sit and get crispy.
Keep cooking for 10-15 more minutes until the potatoes are nicely crisp. Add the rest of the spice seasoning near the end of cooking.
Serve the potatoes while warm with eggs and ketchup if that’s your thing.
