Preheat your oven to 350°F / 175°C. Lightly grease a large baking sheet or line it with parchment paper.
In a large bowl, combine the chopped potatoes, minced garlic, olive oil, and chopped mint.
Toss everything together until the potatoes are evenly coated.
Spread the potatoes in a single, even layer on the prepared baking sheet. This ensures they roast evenly and get crispy.
Roast for 40-45 minutes, or until the potatoes are tender and golden brown, flipping them halfway through the cooking time.
Remove from the oven and immediately drizzle with fresh lemon juice.
Season generously with salt and pepper to taste and serve warm.
Cut potatoes into uniform, bite-sized pieces to ensure they cook evenly.
