Sesame Oil vs Olive Oil: The Ultimate Guide to Nutrition, & Uses

This guide breaks down everything you need to know about these two popular oils. We’ll explore their unique flavors, health benefits, and best uses to help you make smart choices for your kitchen and your health.

Understanding the basics: what are olive oil and sesame oil?

Olive oil

Olive oil comes from pressing olive fruit, primarily grown in Mediterranean regions. It’s been a cornerstone of healthy eating for thousands of years. The oil ranges from bold and peppery to mild and buttery, depending on how it’s processed.

This versatile oil works well in everything from salad dressings to roasted vegetables. Its flavor can transform a simple dish into something special.

Sesame oil

Sesame oil is extracted from sesame seeds. It’s prominent in Asian, Middle Eastern, and African cooking. The oil has a distinctive nutty, earthy flavor that can be mild or intensely toasty.

Unlike olive oil, sesame oil is often used as a flavoring agent rather than a primary cooking fat. A little goes a long way in adding depth to dishes.

Complete nutritional comparison

Here’s exactly what you get in each tablespoon of these oils:

Key takeaways from the numbers:

• Both oils are calorie-dense and should be used mindfully
• Olive oil wins for monounsaturated fats and vitamins E and K
• Sesame oil provides more polyunsaturated fats and phytosterols
• Sesame oil contains more omega-6 fatty acids, which most people already get plenty of

Types of olive oil

Not all olive oils are created equal. Understanding the different types helps you choose the right one for each cooking task.

Extra virgin olive oil (EVOO)

Extra virgin olive oil is the gold standard. It’s cold-pressed and unrefined, meeting strict quality standards that ensure the best flavor and nutrition.

The flavor is robust and complex. You’ll taste fruity notes, peppery heat, and sometimes a pleasant bitterness. This oil packs the highest levels of healthy compounds like oleocanthal and hydroxytyrosol.

Antioxidant Content: 50-300mg per kg (varies by origin and processing) Price Range: $8-25 per 16.9 oz bottle Shelf Life: 18-24 months unopened, 6-12 months opened

Best uses: Salad dressings, finishing oil for soups and pasta, bread dips, and low to medium-heat cooking. Don’t save it just for special occasions – use it daily to get maximum health benefits.

Virgin olive oil

Virgin olive oil is also cold-pressed and unrefined, but quality standards are slightly less strict than EVOO. It still offers good flavor and nutrition, though it may have minor defects that keep it from reaching extra virgin status.

Antioxidant Content: 30-200mg per kg Price Range: $6-15 per 16.9 oz bottle

Best uses: General cooking and sautéing when you want olive oil flavor without the premium price of EVOO.

Pure olive oil (or “olive oil”)

This oil blends refined olive oil with virgin or extra virgin varieties. The refining process removes impurities but also strips away much of the flavor and beneficial compounds.

The result is a milder, more neutral oil that won’t compete with other flavors in your dish.

Antioxidant Content: 5-50mg per kg Price Range: $4-10 per 16.9 oz bottle

Best uses: General cooking, roasting, and baking where you want the benefits of olive oil without a strong taste.

Light/extra light olive oil

Don’t let the name fool you – “light” refers to flavor, not calories. This oil is primarily refined with just a small amount of virgin oil added back.

It has the most neutral flavor of all olive oils and the lowest antioxidant content due to processing.

Antioxidant Content: 1-20mg per kg Price Range: $5-12 per 16.9 oz bottle

Best uses: High-heat cooking like frying and baking when you don’t want any olive oil flavor.

Types of sesame oil

Sesame oil varieties differ dramatically in flavor and best uses. Knowing which type you’re buying prevents kitchen disasters.

Untoasted (light/regular/cold-pressed) sesame oil

This oil comes from raw, unroasted sesame seeds. Cold-pressed versions retain the most nutrients and have a delicate, mild nutty flavor.

It’s rich in healthy fats and antioxidants like sesamin and sesamol. The oil has a higher smoke point than its toasted cousin, making it suitable for cooking.

Sesamin Content: 300-700mg per 100g oil Price Range: $6-18 per 16.9 oz bottle Flavor Intensity: 3/10

Best uses: High-heat cooking like stir-frying, salad dressings where you want subtle nutty notes, and any recipe calling for a neutral cooking oil with added nutrition.

Toasted (dark) sesame oil

Made from sesame seeds that are toasted before oil extraction, this oil has an intense, rich, smoky aroma. The flavor is so strong that a few drops can transform an entire dish.

Sesamin Content: 250-600mg per 100g oil (some lost during toasting) Price Range: $8-25 per 8.5 oz bottle Flavor Intensity: 9/10

Best uses: Finishing oil added after cooking, marinades, salad dressings (use sparingly), and flavoring soups and stir-fries. Never use this for high-heat cooking – it will burn and taste bitter.

Black sesame oil

This oil comes from black sesame seeds and often has a richer, more intense flavor than oil from white seeds. Some varieties have a slightly bitter edge that adds complexity to dishes.

The nutritional profile may differ slightly from white sesame oil, potentially offering higher levels of certain minerals and specific antioxidants.

Calcium Content: Higher than white sesame oil Price Range: $12-30 per 8.5 oz bottle Flavor Intensity: 7/10

Best uses: Similar to other sesame oils depending on whether it’s toasted or untoasted, but often favored in traditional medicine and specific regional dishes.

White sesame oil

Made from white (hulled) sesame seeds, this oil is generally milder in flavor. The exact taste depends on whether the seeds were toasted before pressing.

Price Range: $5-15 per 16.9 oz bottle Flavor Intensity: 2-8/10 (depending on processing)

Best uses: Versatile option that works for both cooking and finishing, depending on the processing method.

Smoke point quick reference guide

Understanding smoke points prevents you from damaging your oils and creating off-flavors in your food.

What happens when oil overheats:

• Nutrients break down and disappear
• Harmful compounds like aldehydes form
• Oil develops bitter, burnt flavors
• Smoke fills your kitchen and sets off alarms

Myth-busting: common oil misconceptions

Myth: “Light” olive oil has fewer calories

Reality: Light refers to flavor intensity, not calories. All olive oils contain the same 119 calories per tablespoon.

Myth: You can’t cook with extra virgin olive oil

Reality: Quality EVOO handles medium-heat cooking just fine. Many Mediterranean cultures cook with EVOO daily without issues.

Myth: Expensive oil is always better

Reality: Price doesn’t guarantee quality. Some mid-priced oils offer excellent value. Focus on harvest dates, storage, and reputable producers.

Myth: All sesame oil tastes the same

Reality: Untoasted sesame oil tastes completely different from toasted. It’s like comparing vanilla extract to vanilla beans – same source, different intensity.

Myth: Oil doesn’t go bad

Reality: All oils eventually go rancid. Proper storage extends life, but even the best oils degrade over time. Trust your nose and taste buds.

FAQs

Is it OK to cook with extra virgin olive oil?

Yes, contrary to popular belief, EVOO can handle temperatures up to 410°F. Quality EVOO has a higher smoke point than many people think. However, it’s more expensive than other options for high-heat cooking.

Which is healthier: olive oil or sesame oil?

Both offer health benefits. Olive oil has more research supporting heart health and contains more antioxidants. Sesame oil provides unique lignans and fits well in balanced diets. The “healthier” choice depends on your overall diet and health goals.

Can I use sesame oil for deep frying?

Untoasted sesame oil works for deep frying with its 410-450°F smoke point. However, it’s expensive for this purpose. Never use toasted sesame oil for deep frying – it will burn and taste terrible.

How much olive oil should I consume daily for health benefits?

Research suggests 2-4 tablespoons daily for heart health benefits. The PREDIMED study used about 4 tablespoons daily. Start with 1-2 tablespoons and gradually increase.

Does heating olive oil destroy its antioxidants?

Some antioxidants are lost during heating, but not all. EVOO retains significant beneficial compounds even after cooking. The key is not overheating – stay below the smoke point.

Why is toasted sesame oil so expensive?

The toasting process is labor-intensive and requires skill to achieve the right flavor. Plus, you use much less – a little goes a long way. Quality toasted sesame oil can last months even with regular use.

Can I substitute olive oil for sesame oil in Asian recipes?

You can substitute untoasted sesame oil with light olive oil for cooking, but you’ll lose the nutty flavor. For toasted sesame oil, try using 1/4 the amount of EVOO plus a pinch of toasted sesame seeds.

Which oil is better for weight loss?

Neither oil is specifically better for weight loss – both contain the same calories. The key is portion control and replacing less healthy fats. Use measured amounts rather than pouring freely.

How do I know if my olive oil is real?

Look for harvest dates, producer information, and certifications. Real EVOO should have some bitterness and peppery notes. Be wary of very cheap “EVOO” – it may be diluted or fake.

Is black sesame oil healthier than regular sesame oil?

Black sesame oil may contain slightly higher levels of certain minerals and antioxidants, but the difference is small. Choose based on flavor preference and intended use rather than health benefits alone.
