A guide to Cooking with Fats and Oils

MeghaMay 10, 2021

Some fats and oils can be used when cooking over high temperatures, while some are better suited for use over low or no heat. The following guide lists preferred cooking oils, their smoke points, and their best uses.

The smoke point of a fat or oil is the temperature at which the oil will burn and become damaged. Smoke points for fat or oil can vary depending on the quality and variety of the source ingredients, and on whether the fat or oil has been refined. It’s important to not exceed a fat or oil’s smoke point when cooking.

What About Other Fats and Oils?

Most of the fats and oils listed below have high smoke points and seem safe for cooking, but these fats and oils undergo heavy processing. These processing methods counteract any potential health benefits. These fats and oils are also high in omega-6 fatty acids, which can cause chronic inflammation in the body. Because of this, regularly consuming fats and oils from this list is not recommended. If you do consume these fats and oils, be sure to choose brands that are certified organic and made from non-GMO crops.

What Does It All Mean? There are many different ways to describe oils, and deciphering food labels with these different words can be confusing. Some common descriptors found on packaging include the following:

Refined Oilsthat are extracted and treated with heat or chemicals in order to remove flaws. This process can also destroy the beneficial properties of oils. Refined oils are generally more stable than unrefined oils, so they are better choices for most high-heat cooking and baking. “Light” oils are examples of refined oils.
Unrefined Oilsthat are made from cold-pressed source ingredients, and are never treated with chemicals or heat. These oils retain all of the minerals, enzymes, vitamins, and phytonutrients of the source ingredient. Virgin and extra-virgin oils fall under this category.
Extra-Virgin Oilsthat are unrefined and cold-pressed, and are generally from the first pressing of the source ingredient. These oils can be fragile, so they should be reserved for dressing, drizzling, and dipping. Note that olive oils must meet specific requirements for acidity in order to be labeled as “extra-virgin.”
Virgin Oilsthat are unrefined and cold-pressed, and are generally from the second pressing of the source ingredient. These oils are also fragile and should be reserved for low-heat cooking, dressing, and drizzling. Virgin oils must pass standards for taste and quality, but the standards are not as rigid as those for the “extra-virgin” qualification.
Pure Oilsthat are a blend of refined and unrefined oils. All of the oil comes from a first pressing, but some of the batches of oil may be treated with chemicals or heat to remove impurities before bottling.
Cold-Pressed Oilsthat are extracted from their source using pressure only. Chemicals and heat are not used in this process. This helps the oils retain all of the nutritional benefits of the source ingredient.
