The Best Cooking Oils for High-Heat Cooking

Not all oils are the same—you’ll want to choose the optimal fat for searing steaks, stir-frying veggies or deep-frying chicken. This guide breaks down which oils can handle the heat, why smoke point matters, how different oils stack up nutritionally and which ones work best in your HexClad cookware.

What Is a Smoke Point and Why Does It Matter?

The smoke point is the temperature at which oil starts to break down, burn and smoke—and that's where things can go sideways in the kitchen. Once an oil hits this point, it doesn't just taste bad. It can release acrolein—the toxic compound responsible for that burnt, bitter taste—and degrade into potentially harmful free radicals.

If you're cooking with heat above 400°F (think: searing, stir-frying, or oven-roasting at high temps), you need a cooking oil that can keep its cool under pressure. Low smoke-point oils will scorch, ruin your dish and potentially coat your HexClad pans with a sticky, burnt layer that's tough to clean. So save that nice extra-virgin olive oil or walnut oil for a salad dressing.   

HexClad pans retain and distribute heat like a dream, which makes it even more important to pick oils that can match the performance. You want something stable, clean-tasting and versatile. Let’s break down the winners.

Which Oils Have the Highest Smoke Points for Cooking?

Avocado Oil (Smoke Point: 520°F)

• Flavor: Neutral to slightly nutty.
  

• Why it's great: It boasts the highest smoke point on the list. Avocado oil is rich in monounsaturated fats and stable under serious heat. Works beautifully in cast iron, stainless, and of course, HexClad Hybrid pans.
  

• Best for: Searing steaks, deep-frying, stir-frying, pan-frying and oven-roasting.
  

Refined Safflower Oil (Smoke Point: 510°F)

• Flavor: Light and neutral.
  

• Why it's great: This is a clean-tasting oil that won’t interfere with your food’s flavor. Its high smoke point makes it ideal for pan-frying and high-heat sautéing.
  

• Best for: Breaded proteins, vegetable sautés, shallow frying.
  

Refined Peanut Oil (Smoke Point: 450°F)

• Flavor: Mildly nutty.
  

• Why it's great: A classic for Asian-style cooking. Peanut oil is a high-performance oil that holds its own in wok-level temperatures. It also adds a subtle depth to stir fries without overpowering the dish.
  

• Best for: Stir-frying, deep-frying, pan-fried noodle dishes.
  

Grapeseed Oil (Smoke Point: 420°F)

• Flavor: Clean and neutral.
  

• Why it's great: High in polyunsaturated fats and Vitamin E. While its smoke point is slightly lower than the others, it holds up well to most cooking methods and won't interfere with delicate flavors.
  

• Best for: Sautéing, pan-searing fish, vinaigrettes.
  

What About Popular Oils Like Olive Oil and Coconut Oil?

Extra-Virgin Olive Oil (Smoke Point: 375–405°F)

• Flavor: Rich and grassy; varies by origin.
  

• The catch: EVOO is a staple in most kitchens, but it’s not built for serious heat. The lower smoke point means it's better for medium-heat cooking or finishing dishes.
  

• Pro tip: Save the good stuff for salads or to drizzle over pasta. For searing, switch to refined olive oil, which is sometimes just labeled “olive oil” or “light olive oil” (smoke point: 465°F).
  

Coconut Oil

• Unrefined (Virgin): 350°F smoke point.
  

• Refined: 450°F smoke point.
  

• Flavor: Sweet and tropical.
  

• Best use: While unrefined coconut oil isn't suitable for high-heat cooking, the refined version can go the distance. It also has a much milder coconut flavor than the unrefined version, which is assertively coconutty.
  

Butter vs. Ghee (Clarified Butter)

• Butter: 350°F smoke point.
  

• Ghee: 485°F smoke point.
  

• Why ghee wins: Ghee is just butter that has had its milk solids toasted (for flavor) and then strained out. Milk solids are the part of butter that makes it burn, so removing them increases the smoke point. That makes ghee or clarified butter perfect for high-heat sautéing and roasting.
  

How Do Health Benefits Compare Across High-Heat Oils?

There’s more to an oil than just heat performance. If you’re concerned about nutrition, here’s how the leading contenders stack up:

Avocado Oil

• Rich in monounsaturated fats (the heart-healthy kind).
  

• Contains lutein (great for eye health).
  

• Naturally high in Vitamin E and antioxidants.

Olive Oil (Refined or Extra Virgin)

• Monounsaturated and packed with polyphenols.
  

• Anti-inflammatory and antioxidant benefits.
  

• Extra-virgin has a lower smoke point but is excellent for medium heat and finishing dishes.

Grapeseed Oil

• High in polyunsaturated fats and Vitamin E.
  

• Omega-6 fatty acids.
  

• Good for high-heat use.
  

Peanut & Safflower Oil

• Stable under high heat.
  

• Lower nutrient density compared to avocado or olive oils.
  

• Subtle nutty flavor that complements many Asian dishes and deep-fried foods.

When it comes to everyday high-heat cooking, aim for a mix: avocado oil for its nutritional value, safflower or peanut oil when you need serious searing power and refined olive oil for moderately high-heat cooking in which you want a Mediterranean flavor. 

What Oils Work Best in HexClad Pans for Different Techniques?

Your cookware can handle the heat—so your oil had better keep up. Here's how to match oil and technique with your favorite HexClad tools.

Searing Steaks (HexClad Fry Pan or Griddle)

• Use avocado or grapeseed oil.
  

• Both stay stable above 500°F and won’t break down before your steak gets its sear.
  

Stir-Frying (HexClad Wok)

• Go with refined peanut oil or grapeseed oil.
  

• High smoke points and fast heat response are perfect for wok cooking.
  

Pan-Frying (HexClad Deep Sauté Pan or Fry Pan)

• Safflower or canola oil work great for crisp, even browning.
  

• They have neutral flavors that won’t compete with the breading or spices.
  

Roasting Vegetables (HexClad Roasting Pan or Sheet Pan)

• Avocado oil is your best bet for oven temps up to 450°F.
  

• It also helps veggies crisp up without burning.
  

FAQs

Can I use extra virgin olive oil for searing in my HexClad pan?

Not ideal. EVOO's smoke point (375–405°F) makes it prone to burning during high-heat searing. Opt for refined olive oil, avocado or grapeseed oil instead.

Does HexClad's nonstick coating mean I need less oil?

Yes. HexClad’s Hybrid surface requires less oil than traditional pans. That said, a little fat helps build flavor and texture, especially during browning or roasting.

Why does my oil smoke even when using high smoke-point varieties?

Two likely reasons: Either the oil is old or oxidized, or you’ve overheated the pan beyond what the recipe requires. Use a thermometer or heat your pan gradually.

Are expensive oils worth it for high-heat cooking?

Only if you’re using them for flavor. Cold-pressed or extra virgin oils lose their nuance when exposed to high heat. Use refined versions for cooking—save the pricey ones for dips, dressings and finishing touches.

Can I reuse oil after high-heat cooking?

You can—briefly. Strain it, store it in an airtight container and reuse it no more than 2–3 times. Discard if it smells off, darkens or smokes earlier than expected.

TLDR

If you're cooking with high heat, your oil choice matters for both your health and the taste of your food. Avocado oil is a top performer with a high smoke point and health benefits. Safflower, grapeseed and peanut oils are all excellent for specific tasks. Use refined olive oil or ghee when you want flavor plus flexibility, and always avoid low smoke-point oils when you're working with high-temp cookware like HexClad.
