Wash your potatoes well. Set them in a large pot, add just enough water to cover them, and boil until easily pierced with a fork (about 15 to 20 minutes).
Preheat oven to 425 degrees F.
Drain the potatoes and let them cool slightly. Transfer them to an oiled sheet pan, leaving a bit of room in between each potato since they will expand when smashed.
Using the bottom of a glass or a mason jar, carefully press down on each potato to smash them into thin, scraggly disks.
Brush each smashed potato with olive oil. Sprinkle with garlic powder, onion powder, and pepper (or seasonings of your choice).
Bake the potatoes in the preheated oven for about 25 minutes, flipping once halfway through. Baking time will vary a bit based on the size of your potatoes. Keep an eye on them and remove from the oven when they’re crispy and delicious.
Sprinkle with salt and enjoy!
