The best oils for stir frys are the oils with the higher smoke points. These tend to be the “thinner” oils such as peanut, grapeseed or canola.
Chinese cooks normally use soybean oil, vegetable oil, or peanut oil, all of which have a high smoke point. Peanut oil usually has a pleasant nutty flavor and is suitable not only for stir-frying but also for deep-frying. Canola oil, which has a high smoke point but a neutral flavor, is also a good choice.
Use olive oil to stir-fry or sear a steak.
Though it's nice to have two oils (one for cooking, such as canola oil, and one for finishing, such as extra-virgin olive oil), here's a secret: We use extra-virgin olive oil for high-heat applications, too.
Oil: Although you can use almost any kind of cooking oil while you master how to make stir-fry, peanut oil is ideal. It can reach a higher temperature than other oils before it starts smoking. (If you have a nut allergy, other high smoke-point oils such as canola or avocado oil are great alternatives.)
Olive oil is healthiest than canola oil but has a low smoke point, making it unsuitable for stir-fry cooking. On the other hand, canola oil can handle high temperatures, so it is a better choice when you want to cook on high-temperature.
So many different oils, the good news is you can stick with what you know – canola is great! The best oils for stir frys are the oils with the higher smoke points. These tend to be the “thinner” oils such as peanut, grapeseed or canola.
The great thing about this recipe is that you can add whatever you would like! I have added bacon, chicken, and ham. It is the perfect fried rice base and they say the secret ingredient to get the authentic Chinese taste is sesame oil.
Food & Dining
The first is to cook your protein and your vegetable separately, and combine them only after both are fully cooked. A second rule of thumb for stir-frying: Choose one vegetable per stir-fry. Finally, always remember to add liquid only after everything is more or less finished cooking.
Although care must be taken in handling and processing of canola oil and other vegetable oils, canola oil is a safe and healthy form of fat that will reduce blood LDL cholesterol levels and heart disease risk compared to carbohydrates or saturated fats such as found in beef tallow or butter.
Perfecting your stir-fry comes down to which oil you use, we'd recommend an oil with a high smoke point like vegetable oil, sunflower oil or even avocado oil. Sunflower oil is also a great option for frying, making it easy to get crispy on the outside, but still succulent and tender results.
Bottom line: Olive oil is the best all purpose cooking oil: it has a strong fruity flavor and is good at medium temperatures. Vegetable oil has a clean, neutral flavor and is best for cooking at high heat.
In addition to being quick and easy, stir-frying is also healthy. It results in tender-crisp vegetables that retain more nutrients than if they were boiled. And since stir-frying requires only a small amount of oil, the fat content is low.
Soy sauce, sesame oil, a bit of vinegar, or store-bought stir-fry sauces are easy to add to the dish and most stir-fry recipes will include a suggested mixture of liquid. If you don't really have a sauce planned, a bit of bottled soy sauce and some diced garlic or ginger will make a nice basic stir-fry sauce.
Cornstarch! In his book How to Cook Everything Vegetarian, Mark Bittman recommends mixing 1-2 tablespoons of cornstarch with the same amount of water, and tossing this into the stir fry just when it's almost done. It thickens in seconds, picking up the flavors of everything already in the dish and coating evenly.
1] Scrub your wok in hot, soapy water and then dry it over low heat on the stove. 2] Turn the burner on your stove to HIGH and add 2 to 3 tablespoons of oil to the wok. I prefer peanut oil, but any oil can be used – sesame, chili, or canola.
Is Canola Oil Better than Olive Oil? No. Canola oil is high in monounsaturated and polyunsaturated fats, making it technically a heart-healthy option. Olive oil, on the other hand, is rich in antioxidants and anti-inflammatory compounds, making it a better choice for reducing the risk of chronic diseases.
While plant-based fats are considered more heart-healthy than animal fats, canola oil is generally believed to be a healthier option because it is lower in saturated fat than vegetable oil.
Canola Oil Disadvantages
Some studies show that a high ratio of omega-6 to omega-3 can raise your risk of certain diseases and conditions, such as Alzheimer's, obesity, and heart disease. Canola oil is also highly refined. This means it goes through a process that uses heat and chemicals to extract the oil.
Stir-fry onions first, then add hard vegetables such as carrot and broccoli. Quick-cooking vegetables, such as snow peas, leafy greens and bean sprouts, should be added towards the end of cooking. If using vegies that have a combination of both textures, such as gai laan, add the stems first and the leaves later.
Use oil with a high smoking point, like peanut oil or vegetable oil. Avoid using sesame oil or olive oil to cook with. Preheat the wok until the oil is smoking, then keep an eye on the temperature so it's hot enough to sear food and cook quickly but not burning.
The answer: high heat, expert tosses, and something known as 'wok hei. ' As J. Kenji López-Alt writes for Serious Eats, expert cooking with a wok (and the gas range it requires) is one of the main reasons that fried rice from a Chinese restaurant tastes so much better than what you can make at home.
In various Authentic Chinese dishes, sesame oil is used as the primary cooking oil. It is even used in salad dressing because of its rich nutty flavour.
