Preheat oven to 450 degrees.

Bring a pot of salted water to a boil. Add in as many potatoes as you wish to make and cook them until they are fork-tender.

Drizzle a sheet pan with olive oil. Place tender potatoes on the sheet pan, leaving plenty of room between each potato.

With a potato masher, gently press down each potato until it slightly smashes. Rotate masher 90 degrees and repeat. Drizzle or brush the tops of each potato with more olive oil.

Sprinkle with salt, pepper, herbs, and parmesan.

Bake for 20-25 minutes until golden brown and sizzling.
