When cooking a steak or any high-heat dish, the choice of oil can make a big difference. Some oils handle the heat well, staying stable and helping create a crispy, golden exterior while keeping the inside juicy and tender. Others break down quickly, smoke, or develop bitter flavors, which can ruin the dish.

Using oils with a high smoke point is not just about flavor—it also helps prevent the formation of harmful compounds that can occur when delicate oils are overheated. The right oils let you sear, roast, or fry at high temperatures without compromising taste or safety.

In this guide, we’ll go through the best oils for high-heat cooking, how to use them, and which oils you should avoid to get the most consistent, flavorful results in your kitchen.

Top Oils for High-Heat Cooking and Why They Work

1. Peanut oil

Peanut oil is one of the most reliable choices for high-heat cooking because it can handle temperatures of up to about 450°F (232°C) without breaking down. Its mild, slightly nutty flavor enhances savory dishes without overpowering them, making it a favorite for deep-frying, stir-frying, and even wok cooking. It heats quickly, holds its temperature well, and gives foods like crispy chicken, golden fries, and crunchy vegetables that perfect, restaurant-quality finish. Another reason many cooks choose peanut oil is affordability — it’s often cheaper than avocado oil, especially when you need larger quantities for deep-frying. The only downside is that it’s unsuitable for anyone with a peanut allergy, so if you’re cooking for a crowd, safer alternatives include canola oil, refined coconut oil, or high-oleic sunflower oil, which also perform well under high heat.

2. Avocado Oil

If I had to pick just one oil for high-heat cooking, avocado oil would be near the top of my list. The refined version has one of the highest smoke points of any cooking oil — around 520°F (270°C) — which makes it perfect for searing steaks, roasting vegetables, grilling, and even deep-frying. Because it stays stable under heat, you won’t deal with smoke, bitter flavors, or burnt oil smells.

Health-wise, avocado oil is a powerhouse. It’s loaded with heart-friendly monounsaturated fats like oleic acid, plus vitamin E and antioxidants that help fight inflammation and oxidative stress. Its flavor is light and slightly buttery, so it won’t compete with the taste of your dish.

I use it when I want foolproof results at high heat — like blistering hot cast-iron sears, crispy roasted potatoes, or even the occasional deep-fry. It costs a bit more than other oils, but buying in bulk (hello, Costco!) can make it much more affordable.

3. Clarified Butter (Ghee)

Clarified butter, or ghee, is pure butterfat with the milk solids and water removed, giving it a high smoke point of about 450°F (232°C). This makes it ideal for searing steaks, pan-frying, or sautéing at high heat without burning.

What makes ghee special is its rich, nutty flavor, which enhances the natural taste of meats and vegetables alike. Unlike regular butter, it won’t brown too quickly or create burnt flavors, so it’s perfect for achieving that golden, crispy edge. It’s also lactose- and casein-free, making it easier to digest for many people with dairy sensitivities. I often use ghee when cooking eggs, roasting vegetables, or giving meats a flavorful sear — it’s one of my go-to high-heat fats.

4. High-Oleic Sunflower Oil

Not all sunflower oil is created equal — if you want to cook at high heat, look for the high-oleic version. This variety is specially bred to have a higher amount of monounsaturated fats, which makes it much more heat-stable than regular sunflower oil (which contains more polyunsaturated fats that can break down under high temperatures). With a smoke point of around 450°F (232°C), it’s a great choice for oven roasting, deep frying, or cooking in large batches.

High-oleic sunflower oil is also easy to find in most supermarkets, budget-friendly, and has a light, almost undetectable flavor. That makes it ideal for recipes where you don’t want the oil competing with the taste of the food.

Personally, I like using it for roasting sheet pans of vegetables when I’m meal-prepping for the week or when frying foods that tend to absorb a lot of oil, like fritters or slices of eggplant. Since the flavor is neutral, it works well for anyone who prefers their food to taste clean and simple.

5. Grapeseed Oil

Grapeseed oil is a versatile high-heat oil that I often reach for when I want something light but dependable. With a smoke point around 420°F (216°C), it holds up well for searing steaks, sautéing vegetables, or pan-roasting proteins without smoking or creating any unpleasant flavors.

One of the reasons I like grapeseed oil is its mild, neutral taste. It doesn’t compete with the natural flavor of the food, so your seasoning and ingredients remain the star. On top of that, it contains vitamin E and antioxidants, giving a small nutritional boost while you cook. Whether you’re aiming for a perfectly seared steak or a quick vegetable stir-fry, grapeseed oil is a solid, reliable choice for high-heat cooking.

6. Refined Coconut Oil

When it comes to coconut oil, it’s important to choose refined over virgin if you plan to cook with high heat. Refined coconut oil is processed to remove most of the strong coconut aroma and raise its smoke point to around 450°F (232°C). This makes it a reliable option for stir-frying, shallow frying, or even high-temperature baking.

Because it’s primarily composed of saturated fats, refined coconut oil is very stable under heat and resists oxidation better than many other cooking oils. While saturated fats often get a bad reputation, they are actually excellent at holding up to high temperatures, which is why this oil stays consistent and doesn’t break down easily.

I like to use refined coconut oil when making Thai-style stir-fries, roasting chickpeas until they’re crispy, or frying up plantains. Its neutral flavor means you can use it in both savory dishes and baked goods — I’ve even used it for making crunchy granola that requires a hot oven. One small tip: since coconut oil tends to solidify at room temperature, gently warm it before measuring to make cooking a little easier.

7. Refined Olive Oil

Olive oil often gets a bad rap when it comes to cooking, but that’s mostly because people confuse extra virgin olive oil (EVOO) with all olive oil. EVOO is perfect for cold uses like drizzling over salads, finishing pastas, or making dressings — but for high-heat cooking, you’ll want refined olive oil. This version has been filtered to remove impurities, which gives it a higher smoke point of about 465°F (240°C), making it a safe choice for sautéing, roasting, and even pan-frying.

Refined olive oil still carries a gentle, fruity olive flavor, but it’s much milder than EVOO, so it won’t take over your dish. You still benefit from its heart-healthy monounsaturated fats, just with more versatility in the kitchen.

I use refined olive oil when I want to quickly sauté greens, brown onions, or roast a tray of potatoes at medium-high heat. It’s also a nice choice for finishing pasta when you want a light, clean flavor without the strong punch of EVOO.

8. Canola Oil

Canola oil is a versatile and widely used cooking oil that performs well under high heat. With a smoke point around 400°F (204°C), it’s suitable for searing steaks, sautéing vegetables, or pan-frying proteins without burning or developing off-flavors.

One of the biggest advantages of canola oil is its neutral taste, which lets the natural flavors of your food shine through. It’s also low in saturated fat and high in heart-healthy monounsaturated fats, making it a smart choice for everyday cooking. I often reach for canola oil when I want a reliable, budget-friendly oil that won’t interfere with the seasoning or texture of my dishes.

Oils to Avoid for High-Heat Cooking

Some oils just aren’t built for high temperatures — they smoke, burn, and lose their flavor or nutrients. Here are the ones to skip when searing, frying, or roasting.

1. Extra Virgin Olive Oil (EVOO): Loved for its fruity flavor and heart-healthy fats, EVOO is a kitchen staple — but it’s not the best choice for high-heat cooking. With a smoke point of about 375°F (191°C), it can begin to smoke and break down when used for frying, searing, or roasting at high temperatures. This not only affects the taste of your food but can also destroy some of its beneficial antioxidants.

EVOO is best saved for lower-heat cooking or cold uses. Drizzle it over salads, finish a pasta dish with a splash, or use it for light sautéing at medium heat to keep its flavor and nutrients intact. If you need an oil for high-heat cooking, switch to refined olive oil — it has a higher smoke point and a more neutral taste, making it perfect for roasting and pan-frying.

2. Unrefined Coconut Oil: While coconut oil is popular for its flavor and health benefits, the unrefined (virgin) version has a relatively low smoke point of about 350°F (177°C). This means it can start smoking and burning when exposed to high temperatures like frying or searing, which not only creates a harsh taste but can also destroy its delicate nutrients.

Instead of using virgin coconut oil for high-heat cooking, save it for gentle sautéing, light baking, or no-heat uses where its natural coconut aroma can shine. If you love cooking with coconut oil but need something that can handle higher heat, switch to refined coconut oil — it has a higher smoke point and a milder flavor, making it much better for stir-frying or shallow frying.

3. Walnut Oil & Pumpkin Seed Oil: These gourmet oils might taste amazing, but with smoke points around 320°F (160°C), they’re far too delicate for high-heat cooking. Both are rich in polyunsaturated fats, which makes them highly sensitive to heat — they can quickly burn, turn bitter, and lose their signature nutty flavor when used for frying or roasting.

Instead of cooking with them, save these oils for when you really want to highlight their unique taste. Walnut oil adds a warm, nutty depth to salad dressings, grain bowls, or drizzled over roasted vegetables just before serving. Pumpkin seed oil has a rich, earthy flavor that pairs beautifully with soups, pasta, or even a slice of good bread. Using them as finishing oils lets you enjoy their health benefits and bold flavor without ruining their delicate nature.

4. Flaxseed Oil: With a smoke point of roughly 225°F (107°C), flaxseed oil is one of the least suitable oils for cooking at high temperatures. It’s packed with healthy omega-3 fatty acids, but those same nutrients are extremely sensitive to heat. When exposed to high temperatures, flaxseed oil quickly breaks down, develops a bitter taste, and loses much of its nutritional value.

Rather than using it for frying, roasting, or sautéing, save flaxseed oil for cold applications. It’s excellent drizzled over salads, blended into smoothies, or stirred into oatmeal or yogurt after cooking. This way, you keep its delicate flavor and preserve the health benefits without risking a burnt or unpleasant taste.

How to Know When an Oil is Too Hot

Cooking with high-heat oils is great for searing, frying, or roasting, but even the best oils can go wrong if the temperature gets out of control. Knowing when an oil is too hot is key—not just to avoid burnt flavors, but also to keep your food safe and healthy.

One of the simplest ways to tell is watch the smoke. Every oil has a smoke point, and when it starts to smoke lightly or aggressively, it’s breaking down. At this stage, the oil can produce bitter flavors and potentially harmful compounds, so it’s time to reduce the heat or remove the pan from the stove.

Smell is another clue. Overheated oil often gives off a sharp, almost acrid scent instead of the neutral or mild aroma it had when first poured. If you notice this smell, it’s a clear sign that your oil is beyond its ideal cooking temperature.

For oils with very high smoke points, like refined avocado oil or ghee, the visual and smell cues might take a little longer to appear—but they’re still the most reliable indicators. A simple trick for testing oils without risking your food is to drop a tiny piece of bread or a small vegetable into the hot oil. If it browns too quickly or starts smoking immediately, the oil is too hot.

By learning these signs, you can cook with confidence, avoid burnt food, and maintain the flavor and health benefits of your oils. Keeping your cooking oils in check is just as important as picking the right oil in the first place.
