Ingredients
UnitsScale
4 medium russet or Yukon Gold potatoes
4 tablespoons unsalted butter
3 garlic cloves, minced
1 tablespoon fresh rosemary, chopped
2 tablespoons olive oil
1/2cup grated Parmesan cheese
Salt, to taste
Black pepper, to taste
Instructions
Preheat oven to 425°F (220°C).
Wash and dry the potatoes. Slice each potato thinly across the top, stopping just before cutting through the bottom to keep them intact.
In a small saucepan, melt butter with minced garlic and chopped rosemary over low heat.
Place the sliced potatoes in a baking dish. Drizzle with olive oil and brush generously with garlic butter, making sure to get between the slices.
Season with salt and pepper to taste.
Roast for 45–60 minutes, basting with the garlic butter every 15–20 minutes.
In the last 10 minutes of baking, sprinkle grated Parmesan cheese over the tops of the potatoes.
Continue roasting until the potatoes are golden brown and crispy on the edges. Serve hot.
Notes
Use chopsticks to prevent slicing all the way through the potatoes.
Baste regularly for maximum flavor and moisture.
Try thyme or sage as an alternative to rosemary.
Substitute Parmesan with cheddar or Gruyère for a different cheesy profile.
Store leftovers in the fridge and reheat in the oven to maintain crispiness.
