Preheat the oven to 415°F.
Boil a medium pot of water and season with salt. Add the diced potatoes and boil for 2 minutes. This removes the excess starch that makes potatoes gummy – allowing it to get super crispy in the oven. After 2 minutes, drain and dry.
In an oven safe pan, add the olive oil, garlic and rosemary. Place in the oven for 10 minutes to infuse the oil with herbs and garlic. If you notice the garlic or rosemary getting too brown, remove from the oven.
Add the potatoes to a bowl and coat in the olive oil. Season with salt and pepper and then evenly lay on a parchment lined sheet tray. Make sure there is space between each potato for the best chance at crispy potatoes.
Transfer to the oven and roast for 20 minutes. Remove from the oven and flip over if they are getting too brown and roast for another 15-20 minutes until golden brown.
Serve and Enjoy!
