Preheat your oven to 400 degrees.
In a large bowl, combine the garlic cloves, potatoes, salt and olive oil. Toss well to coat.
Pour onto a baking sheet or large casserole dish and roast for 30 minutes. Flip potatoes only once, halfway through cooking.
Potatoes are done when they are golden and tender. Scatter with parsley and additional (flaky) salt and serve hot.
