Begin by preheating your oven to 200°C/390°F (180°C fan-forced).
Prepare the potatoes by peeling them. If the potatoes are large, cut them into thick wedges, roughly 3cm / 1.2" in thickness. Medium-sized potatoes can be cut into three pieces.
In a roasting pan, combine the potato wedges with olive oil, chicken stock, lemon juice, grated garlic, dried oregano, and salt. Toss the potatoes thoroughly to ensure they are evenly coated with the mixture.
Place the roasting pan in the oven and let the potatoes roast for about 20 minutes. After the initial roasting time, turn the potatoes and continue roasting for an additional 25 to 30 minutes until the liquid is mostly absorbed and you're left with mainly oil in the pan.
For extra crispiness, you can transfer the potatoes to a separate tray. Tilt the original roasting pan to scoop off as much oil as possible, then drizzle it over the potatoes.
Return the potatoes to the oven and roast for another 35 to 40 minutes, turning them once or twice, until they are golden and slightly crispy around the edges.
For the final touch, return the original pan with the garlic juices to the oven for the last 5 to 10 minutes to reduce the juices and give the garlic a golden hue.
Finally, transfer the potatoes to a serving platter, drizzle with the reduced garlic pan juices, and garnish with lemon wedges and fresh oregano if desired. Serve hot and enjoy!
