Add water to a medium-sized pot and bring to a boil. Add potatoes and cook for about 20-25 minutes, until fork tender.
Meanwhile, preheat the oven to 425 degrees. Prepare a large baking sheet by drizzling about 2 tbsp of olive oil on the bottom and moving the pan around until it is fully covered. You can use a pastry brush to spread the oil as well.
Once the potatoes are tender, drain them and let them dry for 1 minute in the colander.
Place the potatoes evenly across the pan. Taking a bowl or cup press down on each potato to smash them. They will spread and be hard to move at this point which is why it's important to have the potatoes evenly across the pan before smashing.
Drizzle about 1-2 tbsp of olive oil over the smashed potatoes. Sprinkle with salt, black pepper, garlic powder, and onion powder.
Place in the oven and bake for about 30 minutes, until crispy.
Serve and enjoy! Feel free to eat them as they are or dip them in your favorite condiment like ketchup or BBQ sauce.
Notes
You can use red or white potatoes for this. In addition, you can opt for fingerling potatoes which might take less time to cook since they tend to be smaller.
