1. Pre-heat oven to 425 degrees. Fill a large pot with cold water. Add potatoes and move to your burner.
2. Boil the potatoes until fork tender. Drain and cool.
3. Line a baking sheet with parchment paper and transfer cooled potatoes to it. Smash each potato with a metal potato masher. Like my cool one from Ikea.
4. Brush about a tablespoon of melted butter on each smashed tater.
5. Sprinkle each potato with Cajun seasoning, garlic salt, Kosher salt, and pepper. You should put about a quarter of the tablespoon for the Cajun and garlic on each, not a full tablespoon per potato.
6. Pop the flavored and smashed potatoes back in the oven for about 25 minutes.

Enjoy!
