For roasting vegetables, Extra Virgin Olive Oil (EVOO) or Avocado Oil are top healthy choices, offering heart-healthy fats and antioxidants, with avocado oil better for very high heat due to a higher smoke point, while EVOO is excellent for moderate heat or finishing, providing rich flavor and polyphenols. Other good options include canola oil and sunflower oil, which are versatile and have beneficial fats, but use a light hand with oil for maximum health benefits.
Verdict: For temperatures up to 180-190C virgin olive oil is a great choice. Better still, extra virgin olive oil (EVOO), which is made from pure, cold-pressed olives, is reported to have the lowest oxidation rate of any cooking oil. This makes EVOO an ideal choice when cooking at home as long as you don't overheat it.
Toss the vegetables with olive oil and season.
Add 1 tablespoon olive oil, 1 teaspoon kosher salt, and 1/4 teaspoon black pepper. Toss to combine. Add more oil if the vegetables still look dry or don't seem evenly coated.
Avocado oil has a similar fat profile to olive oil, but has a higher smoke point, meaning it does not smoke until temperatures of about 480 degrees fahrenheit. This makes avocado oil ideal for high heat cooking applications such as grilling and roasting.
The 9 Best Olive Oil Substitutions
One of the most overlooked kitchen tips is this: water is the enemy of crispness. After you wash your vegetables, drying them thoroughly is absolutely key to that irresistible roasted texture. Excess moisture creates steam in the oven, which leaves your veggies soft instead of crisp.
Largely, the fact that olive oil has a relatively low smoke point, which means that if cooked for too long, or at too high a temperature, it will start to fill your kitchen with clouds of smoke.
Some doctors caution against avocados due to high calories/fat (weight gain), potassium (kidney issues), FODMAPs/polyols (IBS/stomach upset), potential migraine triggers (tyramine), latex allergy cross-reactions, and interactions with blood thinners like warfarin, though moderation is often key for most people, as avocados offer healthy fats and nutrients. The main concerns often relate to specific health conditions or excessive consumption, not the fruit itself being inherently bad.
Safflower oil has a high smoke point of about 510°F (266°C), making it a strong performer for high-heat cooking like searing, frying, and roasting. It has a very mild flavor and is high in heart-healthy monounsaturated fats.
Some of the best anti-inflammatory cooking oils include algae cooking oil, extra virgin olive oil, and avocado oil. These options not only enhance the flavor of your dishes but also provide powerful health benefits.
Basic Formula for Roasting Any Vegetable:
Toss with olive oil, salt, and pepper (or other seasonings of choice). Spread in a single layer on a baking sheet, leaving space between pieces. Roast at 425°F (220°C), stirring halfway through. Remove when tender and golden brown (see timing guide below).
Roasted Potatoes Recipe Substitutes
Both fats can easily be substituted for olive, sunflower, canola, and vegetable oils. The best substitute, in my opinion, is sunflower oil, as it's slightly better for you than vegetable oil.
You can use fresh or dried herbs. If you are using dried, use less because the flavor is stronger. The amount will depend on how many veggies you are roasting. Spices – paprika, smoked paprika, cumin, chili powder, garlic powder, onion powder, turmeric, garam masala, curry powder, crushed red pepper flakes, etc.
We prefer olive oil, but you can opt for vegetable, canola or grapeseed oils instead.
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.
When choosing a cooking oil, it's best to choose an oil high in poly and/or mono-unsaturated fats, which are heart-healthy fats derived foods such as olives, seeds, nuts and vegetables. Olive oil, which is high in monounsaturated fats, is a particularly beneficial choice for heart health.
We conclude that due to its high oleic acid and antioxidant polyphenol content, the consumption of olive oil may be advised as the optimal fat choice in the management protocols for hypertension in both healthy and cardiovascular disease patients.
However, if you do need to deep fry your food, our long-standing advice is that oils like corn and sunflower oils are not recommended for high temperatures. These oils are rich in polyunsaturated fats which can form undesirable compounds when heated at high temperatures.
It's only possible to think of really good Italian cuisine by thinking of olive oil. This “liquid gold” is one of the world's most prized cooking oils and an integral part of Italian cooking and baking.
Alan Titchmarsh, fresh from tending his thirsty monoculture lawn and flowerbeds, has turned his attention to what the rest of us should eat. Avocados, he says, should be off the menu for the sake of the planet. They use too much water. They contribute to deforestation.
Luckily they are extremely beneficial in maintaining a healthy mind and body, especially for Senior Citizens. They are an extremely nutritious super food that can aid in longevity and quality of life. Avocado trees originated in Mexico millions of years ago.
Avocados have a troubling ecological footprint. They're notoriously water-hungry—a single avocado requires anywhere from 50 to 70 gallons of water to grow. This strains local water supplies, especially considering the main avocado-producing regions are in places like drought-ridden California and Mexico.
We start roasting the veggies at 375 degrees F. Then, in his words, when you see the vegetables are cooked through and just starting to brown, raise the temperature to 400 degrees F to get them really, really crispy. They will look dark brown (but not black) all over.
You shouldn't cook with Extra Virgin Olive Oil (EVOO) primarily because it's expensive, and its delicate, complex flavors get lost or become bitter at high temperatures, making it better for finishing dishes; also, while it's actually quite heat-stable due to antioxidants, using cheaper refined oils for high-heat cooking is more economical, saving your good EVOO for salads or bread dipping.
Here are some common cooking oils that contain more of the “better-for-you” fats and less saturated fat: Canola. Corn. Olive.
