Lemony Potato Gratin Recipes

GREEK LEMON POTATOES

Steps:

• Preheat oven to 200°C/390°F (180°Cfan).
• Cut potatoes: Peel potatoes and cut large ones into thick wedges - about 3cm / 1.2" thick - and medium ones into 3 (see photo in post).
• Coat potatoes: Place potatoes in a roasting pan with all the other ingredients. Toss well.
• Roast 45 minutes: Roast for 20 minutes. Turn potatoes, roast for a further 25 to 30 minutes until the liquid is mostly absorbed by potatoes/evaporated and you're left with mainly oil in the pan.
• To crisp the potatoes (optional): Transfer potatoes to a separate tray. (Note 3) Tilt the original roasting pan and scoop off as much of the oil as you can (some juices is ok), then drizzle over the potatoes.
• Roast 35 minutes: Transfer potatoes to oven and roast for 35 - 40 minutes, turning once or twice, until potatoes are golden and a bit crispy on the edges.
• Heat pan juices: Return pan #1 with the garlic juices to the oven for the last 5 - 10 minutes or so to reduce down and make the garlic golden. (Optional, Note 4)
• Plate up: Transfer potatoes to serving platter. Drizzle over the reduced garlic pan juices (or toss potatoes in the pan). Serve, garnished with lemon wedges and oregano if desired.

LEMON-AND-THYME POTATO GRATIN

Steps:

• Heat oven to 400 degrees with rack in center. Place a baking sheet on rack below to catch any drips from gratin. Brush a 10-by-5 1/2-inch gratin dish with melted butter.
• Cover bottom of gratin dish with one-third of potato slices in an even layer. Sprinkle potatoes with one-third each of thyme, nutmeg, and lemon zest; season with salt and pepper. Dot with butter. Add a second layer, and season. Top with a third layer of neatly arranged potato slices. Pour milk over potatoes. Sprinkle with remaining third thyme, nutmeg, and lemon zest, and dot with butter. Season to taste with salt and pepper. Cover with foil.
• Bake for 40 minutes. Remove foil, and continue to bake 10 to 20 minutes, until top is golden brown and potatoes are tender when pierced with the tip of a knife. Serve gratin hot, spooned out into individual servings.

POTATOES AU GRATIN

Steps:

• Preheat the oven to 350°F and set an oven rack in the middle position. Grease an 8-inch (or 2-quart) baking dish with butter.
• In a large mixing bowl, toss the potatoes with the salt and pepper until evenly coated.
• Arrange some of the potato slices, edges overlapping, in a single layer on the bottom of the prepared baking dish. Sprinkle a quarter of the cheese over the potatoes, and then pour a quarter of the cream over the cheese. Repeat with the remaining potatoes, cheese, and cream, forming 4 layers. Pour any leftover cream over top.
• Place in the oven and bake, uncovered, for 60 to 75 minutes, or until the potatoes are tender when pierced with a knife and golden brown on top. Let the dish settle on the counter for about ten minutes. Sprinkle with fresh thyme, if using, and then serve.
• Make Ahead: This dish can be assembled a day ahead; cover tightly with plastic wrap (pressing the wrap directly against the potatoes so they don't discolor), store in the refrigerator, and bake before serving. The potatoes on top will still discolor a bit in the fridge, but it shouldn't be noticeable after baking.

GREEK LEMON POTATOES

Steps:

• Heat the oven to 450 degrees. On a rimmed sheet pan, combine the chicken broth, olive oil, lemon juice and kosher salt. Toss the potatoes in the liquid to coat, then arrange the potatoes in an even layer, cut-sides down. Sprinkle the oregano over the potatoes, if using.
• Roast the potatoes, flipping halfway through, until fork-tender, dark brown and crispy on top, 55 to 60 minutes. (If the potatoes are cooked through but not as crispy as you'd like, run them under the broiler for a few minutes.) Sprinkle with flaky salt and black pepper as desired.

CREAMY POTATO GRATIN WITH CARAMELISED ONIONS

Steps:

• Up to 2 days before serving, heat oven to 200C/180C fan/gas 6. Heat the oil in a large frying pan. Add the onions and thyme, cover, and cook over a gentle heat for 10-15 mins until softened and caramelised. Pour the cream and milk into a large bowl and season well. Add the potatoes and mix to combine.
• Butter a 23 x 28cm ovenproof dish, then layer in half the potatoes. Spread the onion mixture on top, then layer on the remaining potatoes. Press down with your hands. Pour over the milk mixture, which should come just level with the potatoes. If not, add a little more milk until it does. Cover with foil, then bake for 11⁄2 hrs until tender. Remove from the oven and leave to cool. Cover and store in the fridge.
• On the day, heat the oven to 220C/200C fan/gas 7. Uncover the gratin, spread the crème fraîche on top, then sprinkle over the Parmesan. Put in the oven and cook for 30 mins until the cheese is melted, the top crisp and golden brown, and the gratin piping hot. Serve garnished with extra thyme.
