Preheat your oven to 425°F (220°C). A hot oven is crucial for achieving that crispy texture.
Wash and scrub the Russet potatoes thoroughly. You can peel them if you prefer, but leaving the skin on adds extra texture and nutrients. Cut the potatoes into even-sized cubes, about 1-inch pieces.
In a large mixing bowl, combine the cubed potatoes with 1 tablespoon of olive oil, lemon zest, lemon juice, salt, and pepper. Toss until the potatoes are well coated.
Spread the seasoned potatoes in an even layer on the baking sheet. Drizzle the remaining tablespoon of olive oil over the top.
Roast the potatoes in the preheated oven for about 25-30 minutes, or until they are golden brown and crispy. Make sure to flip them halfway through for even cooking.
Once the potatoes are done, remove them from the oven and immediately sprinkle with the chopped fresh basil. Toss gently to combine.
Transfer the crispy lemon roasted potatoes to a serving dish and enjoy them warm as a delightful side dish to your favorite meal.
