Prep: Preheat oven to 425 degrees F. Cover the bottom of a large baking sheet with parchment paper.
Boil Potatoes: Bring a large pot of water to a boil over medium-high heat. Add whole potatoes to the pot and boil for 15-20 minutes or until fork tender. Drain potatoes.
Make Sauce: While the potatoes are boiling, put the Herby Green Sauce ingredients in a small food processor and blend until smooth. Set aside.
Smash Potatoes: Place the boiled potatoes on a parchment-lined baking sheet and use the flat bottom of a glass to smash each one. Drizzle the smashed potatoes with olive oil, sprinkle with salt, pepper, and grated parmesan cheese.
Bake: Move the baking sheet to the preheated oven to bake for 20-22 minutes.
Serve: Enjoy the smashed potatoes with a drizzle of Herby Green Sauce on top!
Notes
Dairy-Free: simply use a dairy-free sour cream and omit the parmesan cheese or use a dairy-free alternative.
Potatoes: highly recommend baby Yukon gold potatoes but feel free to swap out for another type of potato, just make sure they are small in size.
