A Guide to Cooking Oils

A Guide to Cooking Oils
Oil is oil, right? Well, yes and no. A lot of oils are interchangeable, but some really shine when they’re used for one or two specific purposes. They all have different smoke points (the maximum temperature they can be used at before burning), flavors and health benefits. For years I always just kept olive and canola on hand, figuring one of those would work for whatever I needed—and they did. But there are so many oils out there that add nuance, depth and interesting flavor to whatever you’re making. Here’s our guide to some common oils, with tips for using them:

Olive Oil

Olive oil is pretty much the superstar of the cooking world, thanks to its neutral (but flavorful) taste and medium-high smoke point, which makes it excellent for sautéing, or using in vinaigrettes or as a drizzle to add flavor. It’s also full of antioxidants and healthy fats. Look for cold-pressed, extra virgin olive oil, which is pressed by mechanical means (not chemical) and without heat, which better preserves the integrity of the oil. There are lots of different olive oils on the market—this Cooking Channel video primer helps navigate:

 

Coconut Oil

With a medium smoke point (lower if you buy unrefined), coconut oil is perfect for sautéing, baking, smoothies and non-cooking applications (like no-bake desserts). For the most part coconut oil is neutral tasting, but it can slightly alter the flavor of some recipes (but most will be better for it). Coconut oil will solidify as it cools, and many people add it to their diet for nutritional reasons. We even have an entire Healthy or Hype article devoted to it!

Red Palm Oil

Not to be confused with palm kernel oil (a highly processed oil that’s generally considered unhealthy), red palm oil—or “palm fruit oil”— is derived from the fruit of the oil palm tree, not the seeds or kernels. Red palm oil has become trendy in the natural-foods world the past couple of years, touted for its high antioxidant content and cardiovascular benefits. You can use red palm oil similarly to coconut oil, in baked goods, medium-heat frying, or sautéing.

Nut + Seed Oils

Nut and seed-based oils like macadamia, hazelnut, walnut, sesame or almond have very idiosyncratic and deep flavors. While you can cook with these oils, the flavor is better retained at low (or no) heat. Experiment with making dressings and sauces with them, or drizzling on bread, pasta or soups.

Avocado Oil

This oil is often used in beauty products, and is becoming more popular as a cooking oil. Similar to olive oil, avocado oil (even unrefined) has a high smoke point and can be used for sautéing, baking, frying and roasting, among many other uses. The flavor is somewhat buttery and—like that of an avocado—it’s definitely distinct, but doesn’t compete with other flavors.

Canola Oil

The canola flower comes from a cultivated variety of rapeseed, a plant similar to turnips and cabbage. Versions of this oil have also been used as fuel, in oil lamps, and even as a steam-engine lubricant, but since the 1970s scientists and food companies have developed it for culinary use and it has become extremely cheap and widely available, used for everything from baking to frying to salad dressing. Canola—a marketing abbreviation for “Canadian Oil”—has been praised for its neutral flavor and high unsaturated fat content, including omega-3s. Many avoid canola because the plants used to make it are often genetically modified (some sources say up to 90% of the United States’ supply is GMO), and chemical- and heat-based processes are used to extract it. There are organic and non-GMO versions of canola oil available, though.

Grapeseed Oil

Extracted from the seeds of grapes, this oil is exceptionally clean and neutral tasting. You’ll find it in place of vegetable or canola oil in many natural brands of mayonnaise and salad dressings. It can be used in baked goods, and has a moderately high smoke point—so a stir-fry is probably fine, but not deep-frying.

Safflower + Sunflower Oil

Safflowers are an ancient plant that looks like a cross between a sunflower and a marigold, and sunflowers—well, you know what those look like! These two are very similar, clean-tasting neutral oils. Safflower oil, when refined, has a very high smoke point (refined sunflower is also high, but not as high as safflower). You’ll often find safflower oil in margarines.
