Best Cooking Oils Ranked: What's Actually Safe to Cook With

Not all cooking fats are created equal. The oil you heat in your pan every night is one of the most impactful dietary choices you make — and most of the advice you have heard about it is either outdated, incomplete, or funded by the companies selling you seed oils.

Here is every common cooking fat, ranked from best to worst, based on three criteria: oxidative stability when heated, fatty acid composition, and processing methods.

Tier 1: The Best (Use These Daily)

Extra Virgin Olive Oil

Smoke point: 375-405°F | Best for: Everything up to medium-high heat

The most studied cooking fat in human history. Extra virgin olive oil is rich in monounsaturated fats (oleic acid) and polyphenol antioxidants that actually protect the oil from breaking down during cooking.

The myth that needs to die: "You should not cook with olive oil because of its low smoke point." This is wrong. Research from the University of Barcelona and multiple other studies have shown that EVOO is one of the most stable oils when heated — the polyphenols act as natural antioxidants that resist oxidation even at frying temperatures. It outperforms canola oil and sunflower oil in heat stability tests despite having a lower smoke point on paper.

Use it for sauteing, roasting, baking, and pan-frying. Save your best finishing EVOO for dressings and dipping where you can taste it.

Watch out for: Fake olive oil is a real problem. Buy from reputable brands with harvest dates on the bottle. California Olive Ranch, Cobram Estate, and Kirkland Organic are consistently verified as authentic.

Butter and Ghee

Smoke point: Butter 350°F, Ghee 485°F | Best for: Butter for medium heat, ghee for high heat

Butter is mostly saturated fat, which makes it extremely stable when heated. It has been a primary cooking fat for thousands of years across every culture that raised cattle. Grass-fed butter (like Kerrygold) also contains vitamin K2, conjugated linoleic acid (CLA), and butyrate.

Ghee is clarified butter — the milk solids are removed, leaving pure butterfat. This raises the smoke point dramatically and removes the dairy proteins that some people are sensitive to. Ghee is shelf-stable and does not need refrigeration.

Use butter for eggs, sauteing vegetables, baking, and anything where you want that buttery flavor. Use ghee for high-heat cooking, searing meat, and frying.

Avocado Oil (verified brands only)

Smoke point: 520°F (refined) | Best for: High-heat cooking, grilling, frying

Avocado oil has the highest smoke point of any natural cooking oil, making it ideal for searing, stir-frying, and deep frying. It is primarily monounsaturated fat (oleic acid), similar to olive oil.

The critical caveat: Up to 82% of avocado oils tested in university studies were either adulterated with cheaper seed oils or rancid before opening. Only buy from verified brands: Chosen Foods, Marianne's, and CalPure have consistently passed purity testing. If you are unsure about a brand, use olive oil or ghee instead — they have much lower fraud rates.

Coconut Oil

Smoke point: 350°F (virgin), 400°F (refined) | Best for: Baking, medium-heat cooking, curries

Coconut oil is over 80% saturated fat, making it one of the most oxidation-resistant oils available. Virgin coconut oil has a coconut flavor that works well in baking and Asian dishes. Refined coconut oil has a neutral flavor.

It also contains medium-chain triglycerides (MCTs), which are metabolized differently than other fats and may support energy and cognitive function.

Best uses: Baking (substitute 1:1 for vegetable oil in any recipe), curries, stir-frying at medium heat, and anywhere you want a subtle coconut flavor.

Animal Fats: Tallow, Lard, Duck Fat

Smoke point: Tallow 400°F, Lard 370°F, Duck fat 375°F | Best for: Frying, roasting, searing

These are the original cooking fats — used for centuries before the industrialization of seed oils in the 1900s. They are primarily saturated and monounsaturated, making them extremely stable at high temperatures.

Beef tallow produces the best French fries you will ever eat. McDonald's used tallow until 1990, and people still talk about how much better the old fries tasted.

Lard (pork fat) is the traditional fat in Mexican cooking, Southern biscuits, and pie crusts. Properly rendered lard is virtually flavorless and makes the flakiest pastry.

Duck fat is a culinary luxury — roast potatoes in duck fat once and you will never go back.

Where to buy: US Wellness Meats, local butcher shops, or render your own from beef suet or pork fat.

Tier 2: Acceptable (Use Occasionally)

Sesame Oil (toasted, as a finishing oil)

Small amounts of toasted sesame oil for flavor in Asian dishes are fine. Do not use it as a primary cooking fat — it is high in omega-6.

High-Oleic Sunflower Oil

A specially bred variety with a fatty acid profile similar to olive oil. It is debated in the seed oil community — technically a seed oil, but with much lower omega-6 than regular sunflower oil. If you see it in a product and everything else is clean, it is not the worst offender.

Tier 3: Avoid (Seed Oils)

Soybean Oil, Canola Oil, Corn Oil, Sunflower Oil, Safflower Oil, Cottonseed Oil, Grapeseed Oil, Rice Bran Oil

These are the oils to eliminate. They share three problems:

1. Extremely high in omega-6 fatty acids — contributing to the 20:1 omega-6 to omega-3 imbalance in the modern Western diet
2. Extracted with chemical solvents — hexane extraction followed by bleaching and deodorizing
3. Prone to oxidation when heated — polyunsaturated fats are chemically unstable at cooking temperatures, creating potentially harmful oxidation byproducts

These oils did not exist in the human diet before industrial processing. They entered the food supply because they were cheap to produce, not because they were healthy.

How to Make the Switch

You do not need to replace everything at once. Start with these three swaps:

1. Replace your cooking oil — switch from canola/vegetable oil to extra virgin olive oil or ghee for everyday cooking
2. Replace your butter — if you are using margarine or "buttery spread," switch to real grass-fed butter
3. Replace your high-heat oil — switch from canola spray to avocado oil (verified brand) or ghee for searing and frying

That covers 90% of home cooking. The remaining 10% — packaged foods, restaurants, condiments — you can address over time as you learn to read labels and find clean alternatives.

Frequently Asked Questions

Can you cook with olive oil at high heat?

Yes — the common claim that you should never cook with olive oil is a myth. Multiple studies, including research from the University of Barcelona, have confirmed that extra virgin olive oil is one of the most oxidatively stable cooking oils due to its polyphenol antioxidant content. It outperforms canola and sunflower oil in heat stability tests despite having a lower smoke point on paper. Use EVOO for everything up to medium-high heat without concern.

Is avocado oil actually better than olive oil for cooking?

For high-heat applications (searing, stir-frying, deep frying), avocado oil's higher smoke point (520°F versus 375–405°F for EVOO) is a practical advantage. For flavor, finishing, and medium-heat cooking, extra virgin olive oil's polyphenol content and superior flavor quality make it the better choice. Both are excellent Tier 1 oils — the practical answer is to keep both and use each where it performs best.

Does smoke point determine whether an oil is safe to cook with?

Smoke point is a useful but incomplete indicator. An oil can start breaking down and generating oxidation byproducts well before it reaches its visible smoke point. More important than smoke point is the oil's overall oxidative stability — determined by its fatty acid composition and antioxidant content. This is why EVOO, despite a relatively low smoke point, outperforms canola oil in heat stability tests. The real measure is how much oxidation occurs at cooking temperature, not just when visible smoke begins.

Is coconut oil actually healthy, or is that a fad?

The evidence for coconut oil is genuinely favorable for cooking purposes. Its extremely high saturated fat content (over 80%) makes it one of the most heat-stable oils available — it does not generate the toxic aldehydes that polyunsaturated seed oils produce when heated. The controversy around coconut oil relates to its effect on LDL cholesterol — it raises LDL, but primarily the large-particle LDL that is less associated with cardiovascular risk. For cooking stability and oxidative resistance, coconut oil is a legitimately good choice.

Why is butter considered a healthy fat now when we were told to avoid it for decades?

The "avoid saturated fat" recommendations were largely driven by epidemiological research from the 1960s–1980s that has since been extensively criticized for methodological problems, including industry funding and selective data reporting. Butter — particularly from grass-fed cows — contains fat-soluble vitamins (A, D, E, K2), conjugated linoleic acid (CLA), and butyrate, a short-chain fatty acid that supports gut and immune health. No large-scale human study has ever established that eating butter causes cardiovascular disease in people who are otherwise eating a whole-food diet.
