Preheat oven to 425.
In a large pot, boil potatoes until soft & you can stick a fork through them. (usually about 15-20 minutes)
Line a baking sheet with parchment paper. Place boiled potatoes on baking sheet with equal spacing between each potato.
Use the bottom of a glass and press down gently on each potato. If the potato is sticking to the bottom of the glass, spray a little bit of non-stick cooking spray to the bottom of the glass.
In a bowl, melt butter and whisk in mixed garlic. Once fully combined, drizzle over top potatoes.
Sprinkle parsley, salt/pepper & parmesan over potatoes.
Bake in oven at 425 for 15-20 minutes or until crispy.
Garnish with extra parmesan and parsley before serving.
