How to make ultra-crispy smashed fingerling potatoes
These are the easiest and crispiest smashed fingerling potatoes – everyone will love them! Here are detailed step-by-step instructions with pictures for visual reference so any level cook can make them. The full recipe and ingredient measurements are at the bottom of this page in the recipe card.
First, preheat your oven to 425°F.
Then, bring a large pot of water to a boil over high heat and add two teaspoons of salt. Meanwhile, wash and scrub the potatoes under running water. Then add them to the boiling water and cook for 15 – 20 minutes, until they are fork-tender.
Meanwhile, prepare a baking sheet by adding 1 Tablespoon of olive oil and brushing it across the pan.
When the potatoes are done, drain them using a colander and let them sit for 5 minutes until they can be handled safely.
Transfer the potatoes to a greased baking sheet and use the bottom of a cup or fork to gently “smash” them. The thinner the potatoes, the crispier they will be. I like them to be about a ½ inch thick.
Drizzle with the melted butter first, followed by the remaining 2 tablespoons of olive oil. Then, season with the garlic powder, pepper, and ¼ – ½ teaspoon salt.
Bake for about 25 to 30 minutes until the potatoes are golden and extra crispy. No need to flip them!
Serve hot, garnished with parsley, grated parmesan, and flakey sea salt if desired. Enjoy!
