Drizzle oil into a skillet over high heat.
Place a 1-inch layer of frozen hash browns into the skillet.
Leave the heat on high for 5 minutes and let the hash browns simmer untouched.
After 5 minutes, flip the hash browns, and let them sit for another 5 minutes.
Once they're golden brown on both sides, add a pinch of salt and serve immediately. (You can even take them to go.)
