7 Mistakes When Cooking With Olive Oil

Apr 17, 2025

Want to get the best out of olive oil? Avoid these 7 common mistakes:

  1. Overheating the oil: High-quality olive oil can handle heat up to 410°F, but overheating destroys nutrients and flavor.
  2. Choosing the wrong type: Match the oil grade (e.g., Extra Virgin, Light) to your cooking method and temperature.
  3. Improper storage: Keep olive oil in a cool, dark place, away from light, heat, and air to prevent spoilage.
  4. Using expired oil: Check the crush date and use within 9 months for optimal taste and quality.
  5. Adding oil at the wrong time: Timing matters - preheat for cooking, drizzle fresh for finishing.
  6. Believing color myths: Color doesn’t indicate quality; focus on freshness, smoke point, and flavor.
  7. Using too much or too little: Measure carefully to avoid greasy dishes or uneven cooking.

Quick Tip: Store olive oil in dark containers, buy small amounts, and always check the label for crush dates to enjoy its full flavor and benefits.

The 5 WORST Olive Oil Mistakes and How To Avoid Them!

1. Heating Oil Too Hot

Overheating olive oil can ruin its quality. High-quality extra virgin olive oil (EVOO) has a smoke point of 410°F or higher, making it suitable for most cooking methods. However, pushing it past this limit can cause:

  • Breakdown of healthy compounds
  • Unpleasant flavors
  • Loss of nutrients

Temperature Guidelines

Cooking Method Safe Temperature Range Best Uses
Light sautéing 250°F – 350°F Vegetables, eggs
Medium-heat cooking 350°F – 375°F Most stovetop cooking
High-heat cooking Up to 410°F Searing, roasting

Big Horn Olive Oil’s Ultra Premium EVOOs are specially crafted for high-temperature cooking, with smoke points of 410°F or higher. This ensures you can use them for various methods without sacrificing flavor or nutrition.

Watch for signs of overheating, such as:

  • Smoke rising from the pan
  • Strong, unpleasant smells
  • Oil becoming unusually thin
  • Darkened oil color

To avoid these issues, heat your pan slowly and add oil only when it’s time to cook.

2. Picking the Wrong Oil Type

Once you've got temperature control sorted, the next step is choosing the right oil for your cooking.

Using the wrong oil often comes down to not matching its properties - like smoke point and flavor - to the cooking method.

Olive Oil Grades

The type of olive oil you use matters. Each grade has its own uses and heat tolerance:

Grade Best Uses Temperature Range Characteristics
Ultra Premium EVOO High-heat cooking Up to 410°F Top quality, bold flavor
Extra Virgin Olive Oil Medium-heat cooking, baking Up to 375°F Fresh, versatile taste
Light Olive Oil High-heat frying Up to 465°F Neutral flavor, refined finish

Balancing Heat and Flavor

When picking olive oil, think about both its heat tolerance and how its flavor will influence your dish. A bold EVOO can enhance your recipe, but it won't overpower the other ingredients if chosen wisely.

What to Look For

To make sure you're using the best oil:

  • Check the crush date and smoke point on the label.
  • Choose an oil that fits your cooking style - whether you're frying, baking, or sautéing.

For example, Big Horn Olive Oil's Ultra Premium EVOO is perfect for high-heat cooking, offering excellent flavor and retaining nutrients.

3. Poor Storage Methods

Storing olive oil the right way is key to keeping it fresh and preventing it from going bad. If stored incorrectly, olive oil can lose its quality and flavor faster than expected.

Factors That Affect Olive Oil Quality

Several elements can cause olive oil to degrade:

  • Light exposure: UV rays can break down important compounds in the oil.
  • Heat: High temperatures speed up the oxidation process.
  • Air contact: Oxygen exposure can lead to rancidity.

How to Store Olive Oil

To keep your olive oil fresh, follow these tips:

  • Keep it in a cool, dark cabinet, away from heat sources like the stove.
  • Use dark-tinted bottles to block UV rays.
  • Store it in the original container with a tight-fitting cap to limit air exposure.

Best Practices for Storage

Storage Factor Ideal Conditions Why It Matters
Temperature 65–70°F (18–21°C) Slows down oxidation
Light Exposure Minimal to none Protects antioxidants
Container Type Dark glass or stainless steel Shields oil from UV damage
Usage Timeline Within 2–3 months of opening Ensures the freshest taste

Buy Smart, Use Smart

Buying the right amount of olive oil is just as important as storing it correctly. Choose quantities you’ll use within a few months. Brands like Big Horn Olive Oil offer Ultra Premium EVOO in sizes that help maintain freshness for typical household needs.

Warning Signs of Poor Storage

If your olive oil smells rancid or tastes off, it’s likely been stored improperly and has started to degrade.

Up next, we’ll cover how to avoid mistakes when adding olive oil during cooking.

4. Using Expired Olive Oil

Expired olive oil not only loses its flavor but also its nutritional value. Here’s how to identify and avoid using oil that's past its prime.

How to Spot Expired Olive Oil

Fresh olive oil has a fruity scent and a smooth, pleasant taste. If your olive oil shows any of these signs, it’s likely expired:

  • A rancid or stale odor
  • A sour or overly bitter taste
  • A dull, lifeless color instead of its usual bright tone
  • A thicker or stickier texture than normal

Shelf Life: What You Need to Know

The crush date is your best guide to olive oil freshness. For optimal taste and quality, aim to use it within 9 months of that date. Here's a quick breakdown:

Stage Timeline Details
Optimal Within 9 months of crush date Best taste and quality
Past Prime After 9 months Quality and flavor start to decline

Tips to Keep Your Olive Oil Fresh

Follow these steps to make the most of your olive oil and prevent spoilage:

  • Always check the crush date before buying.
  • Buy a bottle size that matches how often you cook.
  • Write down the date you open each bottle.
  • Use older bottles first by rotating your stock.
  • Test the oil’s freshness before using it.

5. Wrong Timing When Adding Oil

When you add olive oil during cooking can make a big difference in flavor and results. Here's how to time it right for different cooking methods.

Sautéing and Pan Frying

For these methods, always preheat your pan with the oil before adding ingredients. Extra virgin olive oil can handle heat up to 410°F, making it a great choice for most stovetop cooking.

Roasting Techniques

When roasting, you have two good options for adding oil:

Timing Method Works Best For
Before Roasting Toss ingredients with oil Ensures even coating and flavor
Midway Through Drizzle oil halfway through Enhances browning and taste

Finishing Dishes

For a flavor boost, drizzle fresh olive oil right before serving. Use this on hot soups, stews, grilled meats, roasted veggies, fresh salads, or warm pasta. Adding it at this stage keeps its taste and aroma intact.

Temperature Tips

Always preheat your pan or oven to the desired temperature before adding food coated with oil. This prevents the oil from being exposed to high heat for too long. Keep temperatures below 410°F when using extra virgin olive oil.

Mistakes to Watch For

Skipping a final drizzle can rob your dish of olive oil's rich flavor and aroma. Timing matters as much as choosing and storing your olive oil, ensuring every dish gets the full benefit of its taste and quality.

6. Color Myths and Oil Quality

The color of olive oil - whether it's golden yellow or deep green - doesn't determine its quality. Instead, the oil's grade and taste depend on other, more important factors.

What Actually Matters

Let's move past the color myth and focus on measurable factors that affect olive oil quality:

Quality Factor Importance
Smoke Point Affects how versatile the oil is for cooking
Freshness Best flavor and quality within 9 months of the crush date
Storage Conditions Helps maintain quality and extend shelf life

The Truth About Smoke Points

A high smoke point means the oil can handle a variety of cooking methods. High-quality extra virgin olive oils are stable at higher temperatures, making them a great choice for everything from sautéing to baking.

"You can't cook with olive oil" - Not true! A good olive oil will have a high smoke point. If your oil burns while cooking, you're probably using a low-grade product.

Tips for Smarter Shopping

When buying olive oil, keep these tips in mind:

  • Choose a size you can use up before the oil loses freshness.
  • Look for smoke point ratings to match your cooking needs.
  • Check the label for production details like the crush date.

The Role of Storage

How you store olive oil matters more than its color. To preserve quality, keep it in an airtight container away from light at room temperature. Even the best olive oil won't last forever - its quality degrades over time, no matter how it looks.

7. Incorrect Oil Amounts

Using the right amount of olive oil is just as important as adding it at the right time. Too much oil can make your dish greasy and lead to waste, while too little can cause food to stick or cook unevenly. To avoid these issues, measure your oil carefully based on the recipe and cooking method. Also, pick a container size that matches how often you cook, and always check the crush date. Using olive oil within 9 months helps keep its flavor fresh and reduces waste.

Olive Oil Types and Uses

Understanding olive oil types can help you avoid cooking mishaps. Higher-quality olive oils generally have higher smoke points, making them suitable for a range of cooking techniques. This ties into earlier tips about common cooking mistakes and helps you make better choices in the kitchen.

Olive Oil Type Smoke Point Best Uses Key Characteristics
Ultra Premium EVOO 410°F+ High-heat cooking, all methods Fresh-pressed, rich flavor, top-tier quality
Extra Virgin Olive Oil 375–405°F Sautéing, baking, roasting Cold-pressed, unrefined, bold flavor

Pure/Regular Olive Oil 320–350°F Light sautéing, mixing Refined, milder taste
Light Olive Oil 320–350°F General cooking Highly refined, neutral flavor

  • High-heat (400°F or more): Ultra Premium EVOO
  • Medium-heat (350–400°F): Extra Virgin or Virgin Olive Oil

  • Raw uses (like dressings): Ultra Premium EVOO for the best flavor

When shopping, check for clear crush dates and buy sizes you’ll use within a few months to keep the oil fresh.
