Yes, olive oil is perfectly fine for roast potatoes and is a popular choice for adding flavor, but for high-heat roasting, regular (light) olive oil or garlic-infused olive oil is often better than extra virgin (EVOO) due to EVOO's lower smoke point, though many recipes successfully use EVOO at moderate temperatures (around 200°C/400°F) for delicious results.
What is the best oil to use for roasting potatoes? You want to use an oil with a mild flavour for your roasties. We prefer olive oil, but you can opt for vegetable, canola or grapeseed oils instead.
Is there a better oil for roasting potatoes? While many swear by duck or goose fat for the crispiest roast potatoes, olive oil is a fantastic plant-based alternative that offers a different but equally tempting flavour profile. Different olive oils have unique flavour profiles to experiment with.
The answer is yes. Read more to learn why. The smoke point of extra virgin olive oil is between 350⁰ - 410⁰ F. Regular olive oil and light-tasting olive oil have a smoke point range 390⁰ - 470⁰ F.
The secret to perfect roasted potatoes involves parboiling for fluffiness, rouging the edges for crispiness, using hot fat in a preheated pan for instant sizzle, and often adding semolina or baking soda to the boil to break down starches, creating a crackly exterior. High heat and not overcrowding the pan are also crucial for achieving that ideal golden, crunchy outside with a tender inside.
To ensure crispy roast potatoes, make sure the fat or oil is really hot before you add the potatoes and make sure the potatoes have been left to steam dry for at least 15 mins.
Olive oil changes the way you bake. It replaces butter and vegetable oil with ease, adding flavor and texture. It's smooth, full of healthy fats, and leaves baked goods moist and tender. Olive oil is great for baking chocolate cake, soft brownies, or quick breads.
Oils with more monounsaturated fats, such as rapeseed and olive, are also less susceptible to heat. Rapeseed oil (often sold as generic vegetable oil) and inexpensive olive oil are therefore the best choices for cooking.
Gordon Ramsay's 'very best' roast potatoes
Preheat: Add fat to your roasting tray – duck or goose fat roast potatoes are a hit at Christmas, otherwise most oils (bar extra virgin olive oil) work well and cater to vegetarians and vegans.
"Many restaurants also poke holes in the skin but don't wrap the potato in foil, allowing it to crisp up rather than steam," Littley explained. The use of foil doesn't speed up the baking process, but it does trap moisture, resulting in a wet, steamed potato rather than a crispy one.
Nutritionally, frying is the least beneficial method for preparing potatoes, as it adds extra calories without boosting nutrient value. If you're going to fry, using heart-healthy oils like olive or avocado oil and air-frying instead of deep-frying can make a big difference.
Strain the infused oil into a roasting tin, reserving the herbs and spices, then put the roasting tin in the oven for a few minutes. When hot, remove the tin from the oven, then quickly and carefully tip in the potatoes and toss well in the oil. Roast for 50-60 minutes, turning occasionally, until golden and crisp.
Oils high in monounsaturated fats are best for cooking due to their stability when heated and potential health benefits. Examples include olive, avocado, and canola and high-oleic sunflower oil. Coconut oil is also a stable fat for cooking.
How we tested the best fats for roasties
Many chefs consider olive oil to be a "flavor enhancer," bringing out the natural flavors of your ingredients. For instance, extra virgin olive oil enhances the flavor of chocolate making it a perfect choice for brownies.
Vegetable oil can effectively replace olive oil for roasting vegetables. Its higher smoke point allows for crisper results when roasting at higher temperatures. Adding dried herbs or garlic can help compensate for the flavour difference.
The worst cooking oils for health are generally those high in saturated fats (like palm oil, coconut oil, butter) and highly processed vegetable/seed oils (like soybean, corn, sunflower, safflower, grapeseed, cottonseed oil) which are unstable and form harmful compounds at high heat, potentially raising bad cholesterol (LDL) and contributing to inflammation or disease. Partially hydrogenated oils, containing artificial trans fats, are especially bad and should be avoided, though largely removed from products.
Due to the high-calorie content, persons eating more olive oil tend to have less intake of other macronutrients to keep a energy balance. This point may be pertinent to the risk of CVD and mortality which are often observed to be increased among individuals with higher intakes of carbohydrate (41).
It's a great way to add a bit of extra flavor to your veggies or proteins without overpowering their natural taste. For deep-frying -Contrary to popular belief, heating olive oil up sufficient to fry food will not alter its chemical composition so that it becomes unhealthy.
Go for larger chunks of potato so that the sides are bigger. This means more potato will be in contact with your pan or tray, giving it more direct heat to crunch up. The perfect roast potato has a balance of fluff in the middle and crispy exterior. Cut them too small and they're crunchy, but too hard.
It's simple, and it produces amazing results. Boil chunks of potato until they're just tender, toss them none-too-gently with fat (ideally beef drippings) to rough up their surface, then roast them until they're crisp and crackling. The boiling and roughing-up steps are the real keys.
