Corn oil’s mild flavor coupled with a remarkable ability to withstand high temperatures makes it a go-to choice for chefs, particularly when it comes to the art of frying. But what exactly is corn oil?
What is corn oil?
Corn oil, also known as maize oil, is a low-cost cooking oil made from corn kernels.
This refined oil has a high smoke point and a neutral flavor, making it a popular choice for frying in commercial kitchens, but it can also be incorporated into various recipes, including baking and salad dressings.
How is corn oil made?
First, the corn kernels are cleaned and then crushed to separate the germ, which contains the oil, from the rest of the kernel.
The germ is then mechanically pressed or subjected to solvent extraction to extract the oil.
The extracted oil is then refined, which involves processes such as degumming, neutralization, bleaching, and deodorization, to remove impurities and improve the oil’s stability and flavor.
What’s the difference between corn oil and vegetable oil?
While corn oil is a type of vegetable oil, the term “vegetable oil” generally refers to a blend of different oils, including corn oil.
Corn oil is specifically derived from corn, whereas vegetable oil can be a combination of oils like soybean, canola, and sunflower.
However, both corn oil and vegetable oil share similar properties and can be used interchangeably in many recipes.
Benefits of corn oil
Corn oil contains healthy fats: monounsaturated fats and polyunsaturated fatty acids. It’s important to note that corn oil contains higher levels of omega-6 fatty acids, so it should be consumed in moderation to maintain a healthy balance with omega-3 fatty acids.
Its also rich in phytosterols, which helps reduce the absorption of LDL cholesterol, a major contributor to heart disease.
Additionally, corn oil provides a dose of vitamin E, an essential antioxidant that combats harmful free radicals.
One of the best things about corn oil is its high smoke point of about 450ºF, which makes it ideal for high-temperature cooking methods, and its neutral flavor means you can use it for virtually anything!

How to cook and bake with corn oil
Corn oil is versatile and can be used in various cooking and baking methods.
In my experience, corn oil shines in deep frying, thanks to its ability to handle high heat. Use it to fry chicken, fish, or even donuts or churros, for delicious, crispy results.
You can also use corn oil for stir-frying veggies, noodles, or fried rice in a wok.
Another great way to use corn oil is on the grill, where it does a good job of preventing food from sticking and smoking.
In baking, corn oil’s neutral flavor and lightweight consistency make it a good choice for cakes, cupcakes, and muffins, providing a non-stick coating for the pan.

Here are some common dishes and baked goods that often incorporate corn oil:
- Fried chicken, French Fries, and other deep-fried foods
- Fish tacos
- Grilled meats and vegetables
- Cakes, cupcakes, and muffins
- Stir-fried noodles, rice, and vegetables
- Tempura
- Donuts
- Pancakes and waffles
- Cornbread

How to make corn oil at home
While commercial production involves complex machinery and processes, creating your own corn oil can be done with basic kitchen equipment at home. Here’s a simple recipe to follow:
- Start by grinding dried corn kernels into a coarse powder using a blender or food processor.
- Transfer the powder to a pot and add water, simmering the mixture for around 45 minutes.
- Strain the liquid through a cheesecloth or fine sieve to separate the oil from the remaining solids.
- Allow the oil to settle, then skim off any impurities.
- Store the homemade corn oil in a clean, airtight container.
How to store corn oil
To ensure the longevity of corn oil, it’s important to store it properly. Keep it in a cool, dark place away from direct sunlight and heat sources.
An unopened bottle of corn oil can typically last up to 2 years, while an opened bottle should be consumed within a year. Always check the expiration date on the packaging and discard the oil if it becomes rancid or develops an off smell.
What are the best substitutes for corn oil?
For an all-around substitute with a similar neutral flavor, go for canola oil. It won’t overpower the taste of your dishes and works well in most recipes. You can also use any other kind of neutral vegetable oil, such as canola or sunflower oil.
If you need an oil that can handle high heat without smoking, I recommend safflower oil. It won’t break down and ruin your cooking.
And if you want a healthier option for everyday cooking, give virgin olive oil a shot!
