What Are the Healthiest Cooking Oils Ranked by Health? | The Short List

The oil sitting on your counter quietly sets the fat profile of nearly every meal you cook, and swapping butter or lard for a mostly unsaturated oil is one of the few kitchen changes with real evidence behind it. Health organizations keep returning to the same short list, so the ranking below holds up whether you are dressing a salad or searing a steak.

The underlying rule is simple: favor oils low in saturated fat and high in unsaturated fat, then match each oil to the heat you plan to use.

How The Healthiest Cooking Oils Rank

Extra-virgin olive oil takes the top spot, with avocado oil and canola oil close behind for heart-focused cooking.

The American Heart Association’s guidance on fats centers on replacing saturated fat with unsaturated fat, and the Cleveland Clinic names extra-virgin olive oil as the gold standard among cooking oils. Its advantage comes from a high share of monounsaturated fat plus antioxidants called polyphenols, and it appears to hold up better against oxidation than many alternatives.

Avocado oil earns its place mainly on stability — it carries a similar monounsaturated profile and handles higher heat well, which makes it the practical pick for searing, roasting, and grilling. Canola oil rounds out the top tier as a low-saturated-fat, general-purpose oil that works for baking and sautéing without costing much.

Below that tier sit the other unsaturated oils: sunflower, safflower, soybean, corn, peanut, and sesame. All of them beat butter or lard for heart health when they replace saturated fat, even if they lack olive oil’s antioxidant headline.

Which Oil Should You Use For Which Job?

Match the oil to the cooking method, because that matters more than chasing the highest smoke point on the label.

• Extra-virgin olive oil: dressings, finishing, and low-to-medium heat cooking. Overheating is the usual caution, so save the good bottle for where its flavor shows.
• Avocado oil: searing, roasting, and grilling, where its stability under high heat is the whole point.
• Canola oil: baking, sautéing, and everyday all-purpose work.
• Flaxseed and walnut oils: cold use only — dressings and finishing. Heat can strip away what makes them worth buying.

Polyunsaturated oils like sunflower and soybean are genuinely heart-friendly, but they are less suited to long stretches of high heat than the more stable monounsaturated options.

What About Coconut Oil, Butter, And Lard?

Coconut oil sits outside the top tier because of its higher saturated fat content, and butter and lard land at the bottom of heart-focused rankings.

None of these are poison, and none need to disappear entirely. The point is proportion: if most of the fat you cook with is unsaturated, an occasional spoonful of butter is not the thing that decides your health. Coconut oil in particular gets marketed as a health food, but its saturated fat profile is why nutrition sources consistently rank it below olive, avocado, and canola.

One caveat applies across the board — oils are calorie-dense at roughly 120 calories per tablespoon, and the Cleveland Clinic notes that overall dietary pattern matters more than any single bottle.

If you want to skip the label-reading and just stock a kitchen, the tested cooking oil picks worth buying walk through specific bottles that hold up in real cooking.

The Cleveland Clinic’s guidance on choosing and using healthy cooking oils makes one more point worth repeating: smoke point alone is not the whole story. An oil with a very high smoke point can still be a worse choice than olive oil for your heart, so pick by fat profile first and heat second.

Frequently Asked Questions

Is olive oil healthier than avocado oil?

The two are close, and both are strong choices. Extra-virgin olive oil edges ahead on evidence and antioxidant content, which is why it tops most rankings. Avocado oil wins on heat tolerance, so it is the better pick for searing and grilling. Many kitchens keep both and use each where it performs best.

Can I cook with extra-virgin olive oil at high heat?

You can use it for broader cooking, but overheating is a common caution because it can degrade the oil’s flavor and beneficial compounds. For low-to-medium heat and finishing, extra-virgin olive oil is ideal. When you need serious heat, reach for avocado oil instead and save the olive oil for the plate.

Are seed oils like canola and soybean bad for you?

No — they are low in saturated fat and high in unsaturated fat, which is exactly the profile heart organizations recommend. Canola, soybean, sunflower, and similar seed oils are solid everyday choices. They simply rank below olive and avocado oil rather than above them, and they are far better than butter or lard.
