What Are High Smoke Point Oils?
High-smoke-point oils can withstand temperatures of 400°F or higher before breaking down and producing smoke. When oils are overheated past their smoke point, especially when reheated repeatedly, they form unstable free radicals and reactive compounds that can cause harmful health effects when consumed.
According to a 2016 study in Toxicology Reports by Perumalla Venkata and Subramanyam, free radicals formed from overheated oil can contribute to oxidative stress and inflammation in the body.
Chef Tip: For everyday high-heat cooking, avocado oil and canola oil (rapeseed oil) are excellent choices due to their high smoke points and mild flavor. Check out Wikipedia's Smoke Point Chart for a full breakdown of fats and their smoke points.

Cooking with Oils for Heart Health
Not all fats are created equal. Oils rich in monounsaturated and polyunsaturated fats can support heart health by reducing LDL cholesterol and inflammation.
Here's what to keep in mind:
- Use smaller amounts of oil, especially when sautéing, roasting, or baking.
- Avoid deep frying when possible.
- Opt for oils like olive oil, canola oil, and avocado oil for everyday cooking.

Best Oils for Air Fryer Cooking
Air fryers require oils that can handle high, dry heat without smoking or breaking down. The top picks:
- Avocado oil (high smoke point + healthy fats)
- Canola oil (budget-friendly and neutral)
Both oils are great for air fryer recipes due to their mild taste and stability under high heat. Avocado oil tends to cost more but provides a richer nutritional profile.
Consumer Reports notes that not all oils are equal in terms of flavor, smoke point, and nutritional content. For example, avocado oil ranked high for its stability under heat and neutral taste. In contrast, extra virgin olive oil was praised for its heart health benefits in raw or low-heat applications. Oils like canola and safflower also stood out for their versatility and affordability, especially for air frying or sautéing.

How to Know When Your Oil Is Ready for Sautéing
The oil should move more freely in the pan and shimmer slightly when it's hot enough. Here are two ways to test:
- Tilt test: Swirl the oil. If it glides smoothly across the surface, it's ready.
- Bread test: Drop in a small piece of bread-if it sizzles and browns in about 60 seconds, the oil is hot enough.
Chef's Tip: Heat your pan first, then add room-temperature oil. This helps create a nonstick layer and prevents your food from sticking or absorbing too much oil.
Why Not Add Cold Oil to a Cold Pan?
Starting with a cold pan and cold oil can lead to soggy, greasy food. When oil is added to a preheated pan, it forms an invisible barrier between the pan and the food, helping prevent sticking and giving you a better sear.
This is especially important when cooking delicate proteins like fish or when stir-frying. Always give both the pan and the oil time to heat before adding ingredients.
Oils You Shouldn't Cook With
Some oils are best enjoyed raw or as a finishing touch because of their low smoke points and intense flavors.
These include:
- Extra virgin olive oil: Great for dips, vinaigrettes, or drizzling on hummus.
- Toasted sesame oil: Best used as a finishing oil for Asian-inspired dishes.
- Flaxseed oil, walnut oil, and hemp oil: Ideal in salad dressings or smoothies.
Overheating Reactions: Don't worry, you won't get arrested by the oil police if you experiment, but just know the taste and nutritional value can change when overheated.
Olive Oil vs Extra Virgin Olive Oil
A good extra virgin olive oil has a stronger flavor and is great for dipping breads, topping hummus, vinaigrettes, etc. Â Regular olive oil has a milder flavor, making it versatile in cooking despite its low smoke point.
My Review: The Graza Extra Virgin Olive Oil Variety Pack (Sizzle & Drizzle) is a great option if you enjoy cooking with quality olive oil. I’ve used both bottles regularly, and while Sizzle is solid for everyday cooking, the Drizzle really stands out. It’s flavorful, smooth, and has a clean, fresh finish that’s perfect for finishing dishes. The squeeze bottles make it easy to control, and knowing the oil comes from single-farm olives in Spain adds to the appeal. It can feel a bit expensive, but honestly, that’s the reality that good olive oil quality is worth it. Plus, you don't always have to buy the squeeze bottles; they sell refillable cans, perfect for recycling.
Sesame Oil vs Toasted Sesame Oil
Toasted sesame oil, as its name suggests, is made from toasted sesame seeds, which gives the oil a more intense, nuttier taste. Â And this oil is mainly used to finish dishes, not to cook with it.

Oil Storage Tips to Keep Your Cooking Oils Fresh
Proper oil storage is essential for flavor, nutrition, and food safety, especially if you're cooking with oils regularly. Exposure to heat, light, and air can cause oils to break down, go rancid, and lose their health benefits.
- Follow the shelf life: Most oils stay fresh for 3-6 months once opened (especially unrefined or cold-pressed oils).
- Store away from heat and light: Keep oils in a cool, dark pantry or cabinet, not next to the stove.
- Seal tightly: Always close the cap firmly to slow oxidation and prevent off smells or bitter flavors.
- Choose the right bottle: Dark glass bottles help block UV rays and preserve oil quality longer than clear plastic ones.
Chef Tip: If your oil smells "paint-like" or sour, it's gone rancid. Don't risk using it when in doubt; throw it out.

Flavorful & Specialty Oils for Cooking and Finishing
These oils add richness and aroma to dishes but may have lower smoke points or stronger flavors. Use them for medium heat cooking, salad dressings, or to finish a dish for a burst of flavor.
(Regular and Extra Virgin)

Everyday Use: Best used occasionally to add flavor, not as a primary cooking oil.
Artisan & Infused Oils: How to Use Them Wisely
Infused oils like those from La Tourangelle bring aromatics such as garlic, basil, or Herbes de Provence directly into the oil, perfect for finishing dishes or layering in flavor without extra ingredients. While they're not designed for high-heat cooking, they shine in vinaigrettes, light sautéing, or as drizzles over roasted vegetables, grilled meats, and grain bowls.
For example, the garlic-infused oil can elevate a hummus plate or be whisked into a balsamic vinaigrette. The Herbes de Provence oil is excellent on roast chicken or crispy potatoes. These artisan blends are best used when you want to add depth of flavor with minimal effort. Think of them as your secret weapon for restaurant-style finishing touches.
La Tourangelle Infused Oils shine when used intentionally, drizzled over vegetables, mixed into dressings, or brushed onto proteins before roasting. They’re flavor boosters, not workhorse oils.
Cold-Use & Nutrient-Dense Oils for Raw Applications
Best used in dressings, smoothies, or drizzled over dishes, these oils are rich in delicate nutrients and omega-3s but not suitable for high-heat cooking.
Best For: Salad dressings, smoothies, cold dishes.
Smoke Point: Low (~225°F) - not for cooking.
Flavor: Earthy, nutty.
Health Benefits: Rich in plant-based omega-3s (ALA).
Everyday Use: Excellent raw, but not suitable for heat.
Best For: Salad dressings, smoothies, cold drizzles.
Smoke Point: Low (~330°F) - not recommended for cooking.
Flavor: Earthy, grassy, slightly nutty.

Everyday Use: Excellent raw; avoid heat to preserve nutrients.
Best For: Salad dressings, desserts, finishing oil.
Smoke Point: ~320°F.
Flavor: Deep, rich, distinctly nutty.

Chef's Tip: Walnut oil pairs beautifully with roasted beets, leafy greens, fruit-forward salads, and baked goods where a nutty note enhances the dish. Also, think of hemp oil like a finishing oil, great for grain bowls or blended into vinaigrettes, but never for sautéing.
