Follow these detailed instructions to create perfectly crispy and flavorful Parmesan Smashed Potatoes every time:

1. Prepare the Potatoes: Begin by thoroughly washing the potatoes under cold running water. There’s no need to peel them, as the skin contributes to the crispy texture and rustic look. Place the washed potatoes in a large pot.
2. Boil the Potatoes: Cover the potatoes with cold water, ensuring they are fully submerged. Add a generous pinch of salt to the water – this seasons the potatoes from the inside out. Bring the water to a boil over high heat. Once boiling, reduce the heat to medium and simmer gently until the potatoes are fork-tender. This usually takes about 15-20 minutes, depending on the size of your potatoes. You should be able to easily pierce them with a fork without them falling apart.
3. Preheat Oven and Prepare Baking Sheet: While the potatoes are boiling, preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or a silicone baking mat. This prevents the potatoes from sticking and makes cleanup easier.
4. Drain and Cool Slightly: Once the potatoes are tender, carefully drain them in a colander. Allow them to cool slightly for a few minutes – just enough so you can handle them without burning yourself. This slight cooling also helps them crisp up better when smashed.
5. Smash the Potatoes: Transfer the slightly cooled potatoes to the prepared baking sheet. Using the bottom of a glass, a measuring cup, or a potato masher, gently smash each potato until it’s about ½ inch thick. Don’t smash them too thin, as you still want some fluffy potato inside. Aim for a rustic, uneven smash to maximize crispy edges.
6. Drizzle with Olive Oil: Drizzle the smashed potatoes generously with olive oil. Ensure each potato is coated, as the oil is crucial for achieving that golden-brown crispiness.
7. Season Generously: Sprinkle the minced garlic, chopped fresh herbs (rosemary, thyme, and/or parsley), salt, and black pepper evenly over the smashed potatoes. If you are using red pepper flakes, sprinkle them on now as well. Make sure the seasoning is distributed well to flavor every bite.
8. Top with Parmesan Cheese: Generously sprinkle the freshly grated Parmesan cheese over the seasoned potatoes. Ensure each smashed potato gets a good coating of cheese, especially around the edges, as this is where it will crisp up the most beautifully.
9. Bake to Crispy Perfection: Place the baking sheet in the preheated oven and bake for 20-25 minutes, or until the potatoes are golden brown and crispy, and the Parmesan cheese is melted and bubbly, with golden edges. Keep an eye on them towards the end of baking to prevent burning, especially if your oven runs hot.
10. Serve Immediately: Once they are perfectly golden and crispy, remove the Parmesan Smashed Potatoes from the oven. Let them cool for just a minute or two before serving. They are best enjoyed hot and fresh, when the outside is at its crispiest and the inside is still fluffy and tender. Garnish with extra fresh herbs, if desired, and serve immediately as a delicious side dish or appetizer.
