Not skill nor technique, restaurant roast potatoes taste better because chefs use this sneaky trick

January 14, 2026

Roast potatoes are a quintessential side dish, yet many struggle to achieve that restaurant-quality crispiness and flavour. The secret long hidden in restaurant kitchens offers a simple solution: parboiling. This technique elevates the humble potato into a culinary delight, giving it a tender interior and a gloriously crunchy exterior. It’s not just about cooking; it’s about enhancing texture and taste. By employing this one-step trick, countless home cooks can transform their roast potatoes into show-stoppers that rival any restaurant dish.

Traditionally, many think that perfecting roast potatoes relies heavily on precise cooking methods or the chef’s innate skills. However, the key lies in water. Before subjecting potatoes to the oven, a brief boil ensures they achieve an optimal texture. By boiling them in salted water for just a few minutes, the starches come to the surface, promoting that fabulous crispness once roasted. For additional crunch, a touch of baking soda in the water can enhance the effect. This simple yet effective culinary hack not only saves time during cooking but also guarantees satisfying results. Imagine whipping up a batch so good, only a restaurant could rival your kitchen expertise.

Unlocking the Secret of Perfect Roast Potatoes

Achieving that perfect texture in roast potatoes isn’t as complicated as it seems. By adopting the practice of parboiling, the chances of ending up with soggy or undercooked potatoes diminish significantly. The method involves boiling peeled and chopped potatoes in salted water until the edges soften. This step can reduce roasting time and set the foundation for ensuring an irresistible crunch. Aim for about five to seven minutes on the boil, and then finish with your preferred oil and seasonings.

Crucially, keeping the potatoes in the fridge after parboiling can be a game changer for meal prep. This simple act can enhance the flavour and texture, ensuring they are ready to be roasted when needed. The result? Roast potatoes that not only look appealing but burst with flavour, achieving what many would consider restaurant-quality.

A Chef’s Tips for the Perfect Roast Outcome

To ensure roast potatoes shine at your dinner table, consider the variety of potato used. Starchy potatoes like Maris Piper or King Edward are recommended for achieving the best results. These potatoes provide a fluffy inside complementing the crispy exterior, emblematic of great roast potatoes.

Incorporating herbs or spices during the roasting process can further enhance the flavour profile. A sprinkle of rosemary, thyme, or even garlic can elevate the entire dish. Adding these elements as the potatoes roast allows the flavours to permeate, resulting in a culinary experience that pleases the palate.

The Art of Timing and Temperature

Temperature plays a vital role in achieving the desired crunch for roast potatoes. Preheating the oven to a high temperature, ideally around 220°C (428°F), can help seal in the flavours while crisping the edges effectively. Another tip includes ensuring that the oil is hot before adding the parboiled potatoes. This immediate reaction creates a crispy surface that enhances the dish’s overall appeal.

The importance of timing cannot be overstated. Monitor the potatoes as they roast, turning them halfway through to ensure even cooking. This practice guarantees that every angle is subjected to the heat, resulting in perfectly golden and crispy roast potatoes.
