Method
- Scrub potatoes and place them in a large pot. Cover with cold, generously salted water. Bring to a boil and cook until fork-tender, about 15-20 minutes.
- Preheat your oven to 425°F (220°C). While the potatoes cook, prepare your other ingredients.
- Drain the cooked potatoes thoroughly in a colander. Let them sit for 5 minutes to allow steam and surface moisture to evaporate completely.
- Drizzle the olive oil onto a large, rimmed baking sheet and spread to coat. Arrange the dry potatoes on the sheet, leaving space between them.
- Using the bottom of a heavy glass or a potato masher, gently but firmly press down on each potato until it smashes to about a ½-inch thickness.
- In a small bowl, whisk together the melted butter and minced garlic. Brush this mixture evenly over the tops and sides of the smashed potatoes.
- Season generously with salt and pepper. Roast for 20-25 minutes, until the bottoms are golden brown and crispy.
- Carefully remove the baking sheet from the oven. Using a thin metal spatula, flip each potato. Sprinkle the grated Parmesan cheese evenly over the top.
- Return the pan to the oven and roast for another 10-15 minutes, until the cheese is melted and bubbly and the potatoes are deeply golden and crisp.
- Remove from the oven, garnish with fresh chopped parsley, and serve immediately for the best texture.
Notes
Expert Tips: For maximum crispiness, ensure potatoes are completely dry after boiling. A thin metal spatula is essential for flipping without breaking the crispy crust. The high oven heat of 425°F (220°C) is crucial for a perfect result.
Variations: Add 1/2 teaspoon of red pepper flakes to the butter for a spicy kick. For a brighter flavor, toss with fresh lemon zest and juice after roasting. For a 'fully loaded' version, top with crumbled bacon, sour cream, and chives before serving.
Substitutions: Pecorino Romano can be used in place of Parmesan. Fresh rosemary or thyme can be substituted for parsley. For a vegan version, use high-quality vegan butter and a plant-based parmesan alternative.
