Place potatoes and garlic cloves into a baking dish large enough to not crowd the potatoes, thus ensuring they all cook through at the same time.
Drizzle the potatoes with the olive oil and lemon juice. Place into preheated oven to bake for 45 minutes, stirring once part way through the baking time.
Remove from the oven and gently squash the softened garlic cloves over the dish.
Give everything a good stir and then top with feta cheese and a sprinkling of fresh herbs.
Return to the oven and bake for an additional 10 minutes.
