The cooking oil scene has been changing rapidly in the last few years. As the 90s “fat-free” health craze comes to an end, health-conscious home cooks are increasingly interested in healthy fat sources. Enter coconut oil, high in monounsaturated fats, and tons of uses in the kitchen and the household, coconut oil has sky-rocketed in popularity. Then, it seemed like avocado oil stole the spotlight as the next healthy oil. Both of these oils are now readily available in every grocery store when they weren’t popular even ten years ago. Macadamia nut oil is still harder to come by, but worth seeking out. It offers significant advantages in cooking and baking uses and boasts an impressive nutrition profile.
What is Macadamia Nut Oil?
Macadamia nuts are indigenous to Australia, but have since been grown in Hawaii and South America. The oil has only recently been readily available in most US supermarkets as people become more interested in healthy fats. It is a very stable oil that is not prone to oxidation and has a long shelf-life, which sets it apart from other fragile, easily-spoiled nut oils. Macadamia oil is also liquid at room temperature so it’s very convenient for a variety of uses, as you don’t have to melt it first (like coconut oil or ghee).
Macadamia nut oil has a smoke point of 410°F . This makes the oil very stable and suitable for high heat uses such as frying and searing. It won’t burn or smoke when used at temperatures below410°F.
Macadamia nut oil has a very neutral taste. It’s much more neutral than olive oil or unrefined coconut oil, or even ghee. This makes it perfect for baking, as it does not have a savory taste that could throw off a sweet baked good. It can be used as pretty much an all-purpose oil, as one might use vegetable or canola oil.
Macadamia Nut Oil Nutrition

Macadamia nut oil is mostly composed of monounsaturated fat. In a 15 ml serving of macadamia nut oil, it has 2 grams of saturated fat, 11 grams of monounsaturated fat, and 1 gram of polyunsaturated fat. 
Macadamia nut oil is perfect for frying, sauteeing, and roasting. Additionally, because the oil has such a neutral flavor, it’s great for baking, too. It’s perfect for the base of a salad dressing, and to make homemade mayo! You can use it to air fry, and grease a baking pan. Not to mention that it’s also a great oil for moisturizing your skin and hair. The uses are pretty much endless. It has all the convenience of vegetable oil (neutral taste, liquid at room temperature) while being a much healthier alternative these rancid and highly-processed industrial vegetable oils.
Where To Find Macadamia Nut Oil: The Importance of Sourcing
It’s best to get cold-pressed or expeller-pressed oil, preferably organic. This is because in cold-pressing, more antioxidants are preserved that prevent oxidation and spoiling.
Some good brands are Olivado and Milkadamia. I especially like the Milkadamia macadamia nut oil in a spray bottle, which is very convenient for baking and when using the air fryer. It’s also important to make sure you are using macadamia nut oil that is food grade, because many macadamia oils are sold for cosmetic use.
