Lemon Roast Potatoes

Lemon Roast Potatoes

Golden, crispy, and infused with the bright zest of citrus, Lemon Roast Potatoes are a game-changer for your dinner table. Whether paired with succulent meats, tender poultry, or fresh seafood, these flavourful spuds will steal the spotlight. The combination of garlic, rosemary, and lemon elevates the humble potato to something truly special. Unlike traditional roast potatoes, these are designed to be light, zesty, and aromatic, making them a versatile and delicious option for all occasions.

Ingredient Breakdown

  • Maris Piper potatoes: The ideal choice for roasties. Fluffy inside, crisp outside. These potatoes hold their shape well and develop the perfect texture when roasted at a high temperature.
  • Olive oil: Ensures a golden, crunchy finish. A good-quality olive oil enhances the flavour and provides a beautiful crispiness to the exterior.
  • Lemon zest: Adds bright, citrusy depth. The zest contains essential oils that infuse the potatoes with a fresh and fragrant aroma.
  • Lemon juice: Provides a tangy balance to the richness. This touch of acidity lifts the overall flavour and prevents the dish from feeling too heavy.
  • Garlic: Delivers bold, aromatic warmth. The natural sweetness of roasted garlic enhances the savoury notes of the potatoes.
  • Fresh rosemary: A fragrant, earthy herb that complements the lemon. Rosemary pairs beautifully with both citrus and garlic, adding an extra layer of depth.
  • Salt and pepper: Essential for bringing out all the flavours. Seasoning is key to achieving the perfect balance in each bite.

Parboiling Potatoes: Essential for Crispiness

A crucial step for achieving crispy Lemon Roast Potatoes is parboiling. This softens the exterior, allowing the potatoes to develop a golden, crunchy crust in the oven. Begin by cutting the potatoes into large chunks. This helps maintain a fluffy centre. Cover them with cold water, season generously with salt (think sea-level salty!), and bring to a boil. Once bubbling, cook for just four minutes, then drain immediately. Let them steam dry for ten minutes. This step removes excess moisture, helping them crisp up beautifully in the oven.

Parboiling is often overlooked, but it makes all the difference. Without it, the potatoes won’t develop that beautifully crisp outer layer. The key is to boil just long enough to soften the edges but not so much that they begin to fall apart. When drained, the potatoes will look slightly rough around the edges. This is exactly what you want. The rougher the surface, the crispier they’ll become. By allowing them to steam dry, excess moisture evaporates, ensuring that they roast rather than steam once they hit the oven.

The Lemon-Garlic Oil

While the potatoes dry, prepare the flavour-packed oil. In a large roasting tin, mix olive oil, lemon zest, lemon juice, garlic, and rosemary. This vibrant combination ensures every potato is coated in aromatic goodness. If needed, split the mixture between two tins to keep the potatoes in a single layer. Overcrowding leads to steaming rather than roasting, so give them space to crisp up. Once coated, season generously with salt and pepper. Remember, parboiling only starts the seasoning process!

The key to deeply flavoured Lemon Roast Potatoes is ensuring that the lemon and garlic are evenly distributed. The high heat of the oven will mellow the sharpness of the garlic while allowing the lemon to infuse into the potatoes. Some of the zest will caramelise, creating slightly crispy, tangy bites. The rosemary adds an earthy depth that balances the brightness of the citrus. If you prefer an even stronger lemon flavour, consider adding a few thin slices of fresh lemon to the roasting tin alongside the potatoes.

Achieving the Ultimate Crunchy Roastie

For the best Lemon Roast Potatoes, the oven needs to be scorching hot. Preheat to 220℃ and let it reach full temperature before roasting. Bake the potatoes for 30 minutes, then flip to expose their other sides. Continue roasting for another 30 to 45 minutes, tossing occasionally to ensure even crispiness. The high heat caramelises the exterior, locking in flavour while keeping the insides irresistibly fluffy. The result? Golden, crispy perfection with a hint of lemony freshness.

Turning the potatoes halfway through cooking is essential. This ensures every side gets an even chance to crisp up, preventing any soft or soggy spots. As they roast, the edges become crunchy, while the centres remain light and fluffy. Tossing them gently in the oil mixture every so often also helps to build up that crisp coating. The final result should be a deep golden brown with some slightly charred, ultra-crisp edges. This is what makes them so satisfying.

The Importance of Salt

Salt is more than just a seasoning. It’s a crucial step in achieving the perfect Lemon Roast Potatoes. When you parboil the potatoes, adding a generous amount of salt to the water ensures they absorb seasoning from within. If you’ve ever had roast potatoes that taste bland on the inside despite a well-seasoned crust, chances are they weren’t salted properly during boiling. The water should be as salty as seawater to ensure every bite is full of flavour. But the seasoning doesn’t stop there. 

Once drained, the potatoes need another hit of salt before going into the oven. This second layer enhances the crust and helps the potatoes crisp up further. Finally, a last sprinkling of flaky sea salt just before serving adds the perfect finishing touch. By seasoning at every stage, you ensure that the flavour is deep, well-balanced, and never one-dimensional.

Serving Suggestions: Lemon Roast Potatoes

These Lemon Roast Potatoes shine as a side dish for a variety of meals. Their citrusy, garlicky notes pair beautifully with grilled meats and seafood. Try them alongside some of my other recipes, such as:

The bright flavours also make them a fantastic vegan or vegetarian option. Serve them with roasted vegetables, a hearty grain salad, or a dollop of herbed yoghurt for a satisfying meal.

Another fantastic pairing is with Mediterranean-inspired dishes. The combination of lemon and rosemary makes these potatoes an ideal companion for Greek-style grilled lamb, slow-roasted tomatoes, or a mezze platter filled with olives, feta, and hummus. The freshness of the lemon also balances out rich, creamy sauces, making these potatoes a great match for dishes like chicken piccata or a buttery fish fillet.

with garlic and rosemary

Crispy on the outside, fluffy in the middle. These lemony-garlicy-herby potatoes are a delicious alternative to traditional roast potatoes. They’re a great accompaniment to just about anything – meat, chicken, fish, you name it!

Looking for something to pair them with? I recommend my Mojo Marinated Skirt Steak (meat option), Grilled Garlic & Lemon Poussin (poultry option) or Salsa Verde Salmon (pescatarian option).

  • Prep Time: 10 minutes
  • Total Time: 1 hour 30 minutes
  • Yield: 6 1x
  • Category: Vegan, Sides, Vegetarian, Veggies

Ingredients

Scale
  • 1.5 kg Maris Piper potatoes, washed and peeled (optional, I leave the skins on)
  • 180 ml olive oil
  • 2 lemons, zest
  • 1 lemon, juice
  • 6 garlic cloves, crushed
  • 4 sprigs fresh rosemary, leaves only, finely chopped

Instructions

  1. Cut your potatoes into large chunks – into 8 for large potatoes, into 4 for medium potatoes.
  2. Add the potatoes to a large pot and cover with cold water. Add plenty of salt (and I do mean plenty – the water should be sea-level salty) and bring to the boil.
  3. Once the water comes up to a boil, cook the potatoes for 4 minutes. Drain immediately and leave to steam dry for 10 minutes.
  4. Meanwhile, heat your oven to 220℃.
  5. Add the olive oil, lemon zest, lemon juice, garlic and rosemary to a large roasting tin. If you don’t have a roasting tin big enough to fit your potatoes in a single layer, divide the olive oil, lemon zest, lemon juice, garlic and rosemary between two roasting tins.
  6. Add the potatoes to the roasting tin and season with salt and pepper (yes more salt! The potatoes will only have absorbed a little of the salt during the parboiling process). Gently toss the potatoes in the lemony oil.
  7. Roast the potatoes for 30 mins. Flip then roast for a further 30 to 45 minutes, tossing the potatoes every so often to get them golden brown on all sides.
