Introduction to Cooking Oils

What Is Cooking Oil?

In my years as a professional cook, I’ve learned that cooking oil is exactly what it sounds like—fat used to cook, flavor, or finish food. But don’t be fooled by its simple definition. Every oil behaves differently depending on the heat, the ingredients, and even how it’s stored. I treat cooking oil like a tool in my kitchen: the wrong one can ruin a dish—or even damage your pan.

Some basic things every cook should know about cooking oil:

• Oils are either plant-based or animal-based fats.
  
• Every oil has a smoke point—the temperature where it breaks down and starts to taste (and smell) awful.
  
• Some oils add a distinct flavor, while others are designed to be invisible in the final dish.
  

Understanding what what is cooking oil really means has transformed my cooking. Once I started choosing oils purposefully, every dish improved.

Brief History of Cooking Oils

I’ve always found it fascinating that humans have been pressing, rendering, and extracting oils for thousands of years—olive oil in the Mediterranean, lard throughout Europe and Asia, sesame oil in China, and ghee in India. In modern kitchens, industrial production brought us highly refined products like wesson cooking oil. It’s neutral, affordable, and heat-resistant, but it often lacks the flavor and nutrients of more traditional oils.

Nowadays, many chefs, including myself, are returning to traditional oils to recapture that genuine flavor.

Importance of Choosing the Right Cooking Oil

Using the wrong oil can lead to disastrous results. I’ve made my share of mistakes—frying fish in extra virgin olive oil or tossing a salad with canola oil. It’s all about matching the oil to your cooking method and desired flavor.

Here’s what I always consider:

• Heat: Will my dish be cooked on high or low heat?
  
• Flavor: Do I need an oil that stands out or one that stays in the background?
  
• Health: Am I aiming for a source of unsaturated fats, or is a richer, saturated fat acceptable?
  
• Purpose: Is this oil for frying, baking, or dressing?
  

Remember, cooking oil isn’t just a liquid you pour—it’s a vital ingredient that changes everything.

Types of Cooking Oils

There are many types of cooking oils. Lets take a look at all the commonly used ones.

Vegetable Oils

I rely on vegetable oils for their versatility and affordability.

Soybean Oil

Soybean oil is one of the good cooking oils in my pantry. Its neutral flavor and high smoke point make it a reliable choice for frying and sautéing.

Corn Oil

Corn oil offers a mild, slightly sweet taste. It’s excellent for baking and frying, providing consistent heat without overpowering the dish.

Canola Oil

I often use canola oil when I need a best cooking oil that won’t interfere with the other ingredients. Its light, neutral taste is ideal for both cooking and baking.

Nut-Based Oils

Nut-based oils add a unique, rich flavor to dishes. I use them carefully because a little goes a long way.

Peanut Oil

Peanut oil is my go-to for high-heat cooking like deep frying. Its high smoke point and subtle nutty flavor make it perfect for stir-fries.

Walnut Oil

Walnut oil has a distinct, earthy taste that I reserve for raw applications—drizzling over salads or finishing a dish.

Almond Oil

Almond oil brings a delicate, slightly sweet flavor that works well in baked goods and dressings. I sometimes mix it with a neutral oil to balance its sweetness.

Fruit-Based Oils

Fruit-based oils bring both flavor and health benefits.

Olive Oil

Olive oil is indispensable in my kitchen. I use extra virgin olive oil for cold dressings and refined olive oil for cooking. Its flavor is complex, so I balance it with milder ingredients.

Avocado Oil

Avocado oil is one of the healthiest cooking oil for air fryer applications, thanks to its high smoke point and mild, buttery taste. I often use it for grilling and roasting.

Coconut Oil

Coconut oil, with its tropical aroma and flavor, is a favorite in baking and certain ethnic dishes. It behaves almost like butter, solid at room temperature, which gives it unique properties in recipes.

Animal-Based Fats

These traditional fats add an unmistakable depth of flavor to many recipes.

Lard

I use lard for making flaky pastry doughs and for frying. Its rich, savory quality can elevate simple dishes to new heights.

Duck Fat

Duck fat is a luxurious fat that I reserve for special occasions, especially when roasting vegetables or frying potatoes. Its deep flavor can transform a dish into something gourmet.

Ghee (Clarified Butter)

Ghee offers a nutty, aromatic flavor and can handle higher heat than regular butter. It’s a staple in my Indian-inspired recipes and works wonderfully in sautéing.

Specialty Oils

Specialty oils provide unique flavors and should be used in moderation.

Sesame Oil

I love using sesame oil in Asian dishes. Its robust, toasty flavor is perfect as a finishing oil—just a few drops can change the entire profile of a stir-fry.

Flaxseed Oil

Flaxseed oil is prized for its Omega-3 content, but I only use it in cold dishes to preserve its delicate nutrients.

Hemp Seed Oil

Hemp seed oil has an earthy, herbal flavor that works well in salad dressings. It’s not meant for cooking over high heat.

Rice Bran Oil

Rice bran oil is another versatile option with a high smoke point, making it reliable for both frying and sautéing while remaining neutral.

Culinary Uses of Cooking Oils

Best Oils for Frying

When frying, I choose oils with high smoke points. For deep frying, I often use peanut oil or palm olein cooking oil, which is robust and dependable. For shallow frying, canola or corn oil works well.

Deep Frying

• Peanut oil or rice bran oil provides stability at high temperatures.
  
• Wesson cooking oil is a budget-friendly option that I sometimes use when I need a neutral base.
  

Shallow Frying

• Canola oil is great because it doesn’t impart any strong flavors.
  
• Avocado oil can also be used if you want a hint of richness.
  

Best Oils for Baking

For baking, the oil should blend seamlessly with the other ingredients.

Cakes and Pastries

I often choose canola or soybean oil in cakes and pastries because their neutrality lets the other flavors shine.

Bread and Doughs

When making bread, a drizzle of olive oil can enhance both texture and flavor, lending a Mediterranean touch.

Best Oils for Salad Dressings and Marinades

For fresh dishes, extra virgin olive oil is my top pick. Its robust flavor makes a salad pop. Sometimes I mix it with a touch of walnut oil for added depth.

Best Oils for Grilling and Roasting

Grilling and roasting require oils that can stand up to high heat. Avocado oil is my favorite here due to its high smoke point and clean flavor. Occasionally, I use ghee for a more indulgent touch.

Infused and Flavored Oils in Cooking

I like to experiment by infusing oils with garlic, herbs, or chili. A cooking oil spray bottle helps me control the amount I use. It’s amazing how a few drops of an infused oil can elevate a simple dish.

Health Aspects of Cooking Oils

There is a rumor circulating that cooking oils could be bad for your health. And while there some truth to it, in my experience it all depends on the type of oil. Some, are actually beneficial just to inhale in the kitchen…while others not so much. Lets take a look into it.

Nutritional Comparison of Cooking Oils

Every oil has a different nutritional profile, and I choose based on what the dish needs and my own health considerations.

Saturated Fats

Oils like coconut oil, lard, and ghee are high in saturated fats. I use them sparingly if I’m aiming for a healthier option.

Unsaturated Fats

I prefer oils such as olive, avocado, and many nut-based oils because they’re rich in unsaturated fats, which are better for heart health.

Omega-3 and Omega-6 Content

Flaxseed oil is my go-to for Omega-3, while many vegetable oils tend to have higher Omega-6. Balancing these fats is essential.

Vitamin E and Antioxidants

Olive oil and rice bran oil are packed with antioxidants. These nutrients not only benefit health but also help maintain the oil’s quality over time.

Caloric Value of Different Cooking Oils

Every oil gives roughly 120 calories per tablespoon. This means portion control is key, which is why I sometimes use a cooking oil spray bottle to distribute a fine mist rather than pouring directly.

Cooking Oils and Heart Health

For my heart-healthy recipes, I lean toward extra virgin olive oil, avocado oil, and flaxseed oil. They provide beneficial fats that support cardiovascular health.

Cooking Oils and Weight Management

When watching my calories, I rely on a cooking oil dispenser to measure out precise amounts, helping me manage intake without sacrificing flavor.

The Lowest Calorie Cooking Oils

Technically, all oils have similar calorie counts. However, using methods like a cooking oil spray bottle can help you use less oil overall, which is as close as it gets to a low calorie cooking oil option.

Potential Health Risks

Hydrogenated Oils and Trans Fats

I strictly avoid hydrogenated oils and any products with trans fats, as they are harmful to heart health.

Smoke Point and Toxic Compounds

I always monitor my oil’s temperature. Overheated oil can break down into toxic compounds, so knowing your oil’s smoke point is vital.

The smoking points for most oils are the following:

Oil Type	Smoke Point (°C)
Extra Virgin Olive Oil	190–205°C
Refined Olive Oil	240°C
Canola Oil	204°C
Vegetable Oil	204°C
Peanut Oil	232°C
Coconut Oil (Virgin)	177°C
Coconut Oil (Refined)	204°C
Avocado Oil	271°C
Grapeseed Oil	216°C
Sesame Oil	210°C
Butter	150°C

Technical Properties of Cooking Oils

This is not as simple as you might think. Let me explain it to you step by step.

Smoke Point and Why It Matters

In my experience, the smoke point is crucial. High smoke point oils like avocado or peanut oil are ideal for high-heat cooking, whereas oils with lower smoke points are best used in cold or low-heat applications.

Flavor Profiles of Different Oils

Some oils are meant to contribute flavor—extra virgin olive oil and nut oils—while others, like canola, remain in the background. I choose based on whether I want the oil to be a flavor star or a supporting player.

Stability and Shelf Life

Proper storage matters. I always store my oils in a cool, dark place, and I keep an eye on them because can cooking oil go bad? Yes, if not stored properly, oil can become rancid and affect both taste and health.

How to Choose the Right Cooking Oil

Choosing the right oil can make or break it when we cooking specific dishes. When I was working at a fancy restaurant, choosing the wrong cooking oil could have resulted in a very unsatisfied customer, and I have never failed throughout the years of working. This is why I want to share this with you.

Matching Oil to Cooking Method

Every method requires a specific type of oil. For high-heat frying, I use oils with high smoke points. For dressings and finishing touches, I opt for flavorful oils.

Reading Labels and Certifications

Cold-Pressed vs Refined Oils

I pay attention to whether an oil is cold-pressed, which retains more flavor and nutrients, or refined, which is more stable for high heat.

Organic Certification

Sometimes, I choose organic oils to avoid pesticides, though it’s more about personal preference than necessity.

Non-GMO Labels

If I’m particular about ingredients, I look for non-GMO labels to ensure I’m using the cleanest products possible.

Flavor Considerations

A dish’s flavor can be ruined by the wrong oil. I always consider if the oil’s flavor should complement or remain unnoticed in the final dish.

Health and Dietary Needs

For recipes catering to specific diets—like Keto, Vegan, or Paleo—I select oils that fit those guidelines, such as coconut oil, avocado oil, or ghee.

Best Cooking Oils by Category

“Best” is a subjective thing, but sometimes there are some oils, that are generally more preferred vs others.

First, see the table of the calories content in every type of oil:

Oil Type	Calories (per 1 tbsp / 14g)
Olive Oil	120
Canola Oil	120
Vegetable Oil	120
Peanut Oil	120
Coconut Oil (Refined)	120
Coconut Oil (Virgin)	120

Best Overall Cooking Oil

Extra virgin olive oil is my all-rounder. It’s versatile enough for dressings, low-heat cooking, and finishing touches.

Best Oil for High-Heat Cooking

Avocado oil wins here. Its high smoke point makes it perfect for any high-heat application without compromising flavor.

Best Oil for Salads

For salads, I prefer walnut oil. Its rich, nutty taste adds sophistication without overwhelming delicate greens.

Best Budget-Friendly Cooking Oil

For everyday cooking, I sometimes turn to wesson cooking oil—it’s reliable, neutral, and cost-effective.

Best Organic Cooking Oil

I favor organic extra virgin olive oil when I want a natural, pesticide-free option.

Best Cooking Oil for Keto, Vegan, and Paleo Diets

Depending on the recipe, I reach for coconut oil, avocado oil, or ghee—all fit well within these dietary plans.

Storing and Handling Cooking Oils

Storage is important. In fancy restaurant we have dedicated storage units, but if you cook at home or mostly at home, understanding proper storage methods is important. And, of course, the key is keeping them away from the sun, but there is much more to it.

Proper Storage Methods

I always store oils in a cool, dark place, ideally in a container that minimizes exposure to air. A cooking oil dispenser can help maintain the oil’s integrity.

How to Tell If Your Cooking Oil Has Gone Bad

If the oil smells rancid or tastes off, then can cooking oil go bad? Absolutely. Fresh oil is key to a good dish.

Extending Shelf Life

Purchasing oils in smaller quantities and sealing them tightly after each use helps me keep them fresh longer.

Cleaning and Removing Cooking Oil

Yes, spills happen. Let me teach you how to clean them fast & smooth, before you clothes are ruined forever.

How to Remove Cooking Oil from Clothes

I’ve had my share of spills. When it happens, I act fast: blot the area, use dish detergent, and wash in hot water. This method answers the classic question of how to get cooking oil out of clothes.

How to Clean Cooking Oil Spills from the Floor

I usually cover spills with baking soda or flour to absorb the oil, then sweep and mop thoroughly to prevent slips.

How to Remove Cooking Oil Stains from Furniture

For furniture, I gently blot the stain and use a mild soap solution to lift the oil without damaging the surface.

Safety Tips for Cleaning Oil Spills

Always clean spills immediately. Oil is slippery and poses a risk if left unattended.

Sustainability and Environmental Impact

Sustainable Oil Production

I try to support sustainable oil production by choosing brands that prioritize responsible farming practices. This not only benefits the environment but also often yields higher-quality oil.

Environmental Issues with Palm Oil

I’m cautious with palm oil due to its environmental impact. I opt for certified sustainable options like palm olein cooking oil when available.

Choosing Eco-Friendly Cooking Oils

When possible, I select eco-friendly options. Local, organic oils are usually my top picks when I’m trying to reduce my environmental footprint.

Homemade Cooking Oil Blends and Infusions

Yes, mixing 2 types of oils is not only possible, but may unlock unique opportunities for you to make your dishes truly unique. It is a small chef’s secret few people know about.

How to Make Your Own Oil Blends

I’ve experimented with blending oils to create unique flavors. For example, mixing a neutral oil with a small amount of sesame oil can add depth without overwhelming a dish.

Infusing Oils with Herbs and Spices

Infusing oil is one of my favorite techniques. I gently heat oil with garlic, rosemary, or chili, let it cool, then strain out the solids. This technique adds a burst of flavor to any dish.

Safety Tips for Homemade Infused Oils

Always refrigerate infused oils and use them within a week to prevent any risk of bacterial growth.

Cooking Oil Alternatives

If you don’t want to use oil, don’t worry, I’ve got you here! Lets look at some really feasible, from my experience, cooking oil alternatives.

Butter and Margarine

Sometimes, I choose butter or margarine instead of oil. They offer a different texture and flavor, especially in baking.

Broths and Stock-Based Cooking

For low-fat cooking, I occasionally use broths or stocks in place of oil when sautéing vegetables, which adds moisture and flavor without the extra calories.

Yogurt and Other Dairy-Based Replacements

In baking, substituting yogurt for oil can reduce fat content and introduce a pleasant tang to the dish.
