Instructions
- Preheat the oven to 400°F (200°C).
- Cut the peeled potatoes into thick wedges, roughly 1½ inches wide, so they hold their shape through the long cook.
- Arrange the wedges snugly in a single layer in a large baking dish or roasting pan; they should fit fairly tightly so the sauce has less room to spread thin.
- In a bowl, whisk together the olive oil, lemon juice, garlic, oregano, salt, and pepper.
- Pour the mixture over the potatoes and toss well by hand so every wedge is coated.
- Pour the stock or water into the gaps around the potatoes, not directly over the top, until the liquid comes about halfway up the sides of the wedges.
- Cover the dish tightly with foil and roast for 40 minutes so the potatoes steam and start to soften in the lemony liquid.
- Remove the foil, turn each wedge over, and return the dish to the oven uncovered for another 35 to 45 minutes.
- Check the pan around the halfway point of the uncovered roasting; if it looks dry before the potatoes are tender, add a splash of hot water or stock.
- The potatoes are done when a fork slides easily through the center, the tops are golden and slightly caramelized, and the sauce has reduced to a thick, glossy coating rather than a pool of liquid.
- Let the dish rest for 5 minutes, then spoon the pan sauce back over the potatoes before serving warm.
Tips for Success
- Choose a starchy, dense potato like Yukon Gold or Russet; waxy varieties can turn mushy after the long braise-then-roast cooking time.
- Do not skip the final uncovered stretch — that is what evaporates the extra liquid and lets the tops brown, giving the dish its characteristic tender-inside, golden-edged texture.
- Keep the potatoes packed closely in the pan; too much surface area lets the liquid spread out and evaporate too fast, leaving the centers underdone.
- Leftovers reheat best in a hot skillet with a little olive oil, which re-crisps the edges that soften again in the refrigerator.
