First, I preheat the oven to 425°F. While it's heating, I arrange the frozen tater tots in a single layer on a baking sheet, giving each tot a little breathing room. Then I bake them for about 10 minutes so they begin to crisp up on the outside.
After that initial bake, I pull the tray out and gently smash each tot to about ¼-inch thickness using a flat-bottomed glass. I then whisk together melted butter, salt, black pepper, and garlic powder, brushing that mixture lightly over each smashed tot to coat.
Next, I slide the baking sheet back into the oven and bake for another 10-15 minutes, watching until the edges are golden and crispy. Once done, I let them cool just a bit so they firm up, then plate and serve right away—tots are best warm.
