First, preheat your oven to 400°F (200°C). A hot oven is essential for achieving that crispy texture we crave. Lightly spray a baking sheet with cooking oil spray and set it aside.
Next, peel the russet potatoes and cut them into 1-inch cubes. The size is important for even cooking. Place the cubed potatoes in a bowl with cold water for an hour to remove excess starch, which helps them become crispy.
After one hour, discard the water and replace it with fresh, cold water. Let them soak for another hour. This step is crucial for producing crispy potatoes.
Once soaking is complete, drain the potatoes and discard the liquid. Spread them out on a kitchen towel and gently pat them dry with another kitchen towel. This helps to remove any excess moisture.
In a large mixing bowl, add the dried potatoes. Drizzle with olive oil and season with sea salt, freshly ground black pepper, smoked paprika, dried parsley, and minced garlic. Toss everything together until the potatoes are evenly coated.
Arrange the potatoes on the prepared baking tray in a single layer, ensuring enough space between each piece. Crowding the pan can lead to steaming rather than roasting.
Roast in the oven for 45 to 60 minutes. Flip the potatoes occasionally to promote even browning. You’ll know they’re done when they’re crispy and golden brown.
Once out of the oven, taste the potatoes and season with a little extra sea salt and freshly ground black pepper to your liking. Sprinkle with fresh chopped parsley and grated parmesan cheese if desired.
Serve immediately and watch everyone enjoy these delightful bites!
