Begin by preheating your oven to 200°C (390°F) and lining a large baking sheet with parchment paper.
Cut the washed Yukon Gold potatoes into even 2-cm (3/4-inch) cubes, creating uniform pieces that will roast evenly and develop a crispy exterior.
Place the potato cubes into a large mixing bowl, drizzle with the olive oil, and sprinkle generously with salt and freshly cracked black pepper. Toss everything together until each piece is evenly coated and glossy.
Spread the seasoned potatoes in an even layer on the prepared baking sheet, making sure they aren’t crowded to allow maximum crispness.
Place the baking sheet in the oven and roast for about 25–30 minutes, turning the potatoes once halfway through. You’re looking for golden, crispy edges and a tender inside. The garlic will start to smell fragrant and slightly caramelized.
While the potatoes roast, finely chop the fresh parsley, thyme, and basil. Mince the garlic cloves and set aside.
Once the potatoes are nearly done, sprinkle the chopped herbs and minced garlic over them, then return to the oven for the last 5 minutes. This preserves their bright aromas while allowing them to meld with the crispy potatoes.
Remove the baking sheet from the oven, then zest the lemon directly over the hot potatoes for a fresh, zesty aroma. Toss gently to distribute the lemon zest evenly.
Give everything a final gentle toss, taste, and adjust seasoning if needed. Serve immediately while hot and fragrant, garnished with extra fresh herbs if desired.
