Preheat the oven to 400°F (200°C).
Wash and pat the potatoes dry, then slice them into thick wedges. Leave the skins on if desired.
In a small bowl, whisk together the olive oil, fresh lemon juice, oregano, salt, pepper, and finely grated garlic.
Arrange the potatoes in a single layer on a large baking sheet.
Pour the dressing over the potatoes and toss well until evenly coated.
Carefully pour the broth around the potatoes rather than directly over them so the seasoning stays on the surface.
The Greek Lemon Potatoes should be about halfway submerged in the liquid.
Roast for 50–60 minutes, or until the potatoes are fork-tender with crispy golden edges and most of the liquid has been absorbed.
For extra crispy potatoes, roast for an additional 5–10 minutes if needed.
Spoon any remaining pan juices over the potatoes before serving.
