Garlic-infused olive oil is a delicious and versatile ingredient that has found its way into many kitchens worldwide. From drizzling it over a fresh salad to adding flavor to a pasta dish, the uses are endless. However, like any other infused oil, garlic-infused olive oil has a limited shelf life, which depends on how it is made and stored. Knowing how long garlic-infused olive oil lasts and how to store it safely is essential to enjoy its flavor while avoiding potential health risks.
This article dives into everything you need to know about the shelf life of garlic-infused olive oil, including the factors that affect its longevity, how to store it properly, signs of spoilage, and tips for making it safely at home.
What is Garlic-Infused Olive Oil?
Garlic-infused olive oil is made by immersing fresh or roasted garlic cloves in olive oil. The natural oils and flavors from the garlic slowly infuse into the oil, resulting in a rich, savory taste perfect for a wide variety of dishes. Whether used as a marinade, dressing, or cooking oil, it can elevate the flavor of any dish. However, it’s important to note that the addition of garlic can shorten the oil’s shelf life due to the presence of water and natural enzymes in the garlic, which can promote bacterial growth if not handled properly.

How Long Does Garlic-Infused Olive Oil Last?
The shelf life of garlic-infused olive oil varies based on several factors such as the preparation method, storage conditions, and the type of oil used. Generally, if you make garlic-infused olive oil at home, it will last for up to 2 weeks at room temperature and up to 6 months if stored in the refrigerator.
When stored properly in a cool, dark place, commercial garlic-infused oils might last slightly longer due to preservatives and other measures taken during manufacturing. Be sure to read the label for detailed storage guidelines and the product’s expiration date.
The shorter shelf life is largely due to the risk of botulism, a serious illness caused by bacteria that can grow in improperly stored garlic-infused oils. According to the Centers for Disease Control and Prevention (CDC), garlic stored in oil can create the perfect environment for botulinum spores to grow, leading to the production of a potent toxin. This makes proper storage and timely use critical.
Factors That Affect the Shelf Life
Several factors influence how long garlic-infused olive oil lasts, including:
- Type of Oil: Extra virgin olive oil has a higher antioxidant content, which can help slow down spoilage. Refined oils may degrade faster.
- Garlic Preparation: Fresh garlic cloves contain water and enzymes, which can shorten the oil’s lifespan. Using dried garlic can extend the shelf life.
- Storage Conditions: Heat, light, and air exposure can cause oxidation, leading to rancidity.
- Infusion Method: Cold-infused oils typically have a shorter shelf life compared to oils heated during the infusion process, as heat helps to kill bacteria.
To ensure your garlic-infused olive oil lasts as long as possible, it’s essential to follow proper storage and handling guidelines. Proper storage techniques for oils can help extend their freshness and prevent spoilage.
Storing Garlic-Infused Olive Oil Safely
Proper storage is the key to ensuring your garlic-infused olive oil stays fresh and safe to use. Here are the best practices:
1. Use Dark, Airtight Containers
Store the oil in dark-colored glass bottles or stainless steel containers to prevent exposure to light, which can cause the oil to oxidize and spoil faster. The bottle should be airtight to keep moisture and air out, as they can accelerate the growth of bacteria and spoil the oil.
2. Refrigeration
Refrigerating garlic-infused olive oil can extend its shelf life significantly. In the fridge, the oil can last up to 6 months, though it will solidify. You can thaw it at room temperature before use.
3. Label and Date Your Oils
Always label your containers with the date the oil was infused, so you know how long it has been stored. This is particularly helpful for homemade oils.
4. Avoid Room Temperature Storage for Long Periods
If you’re not planning to use the oil within a week or two, it’s best to store it in the fridge. Keeping it at room temperature for extended periods can create the perfect environment for bacteria to thrive.

Signs of Spoilage in Garlic-Infused Olive Oil
Knowing the signs of spoilage can help you determine when it’s time to throw away your garlic-infused olive oil. Here are a few warning signs to keep an eye on:
- Rancid Smell: Fresh oil should smell fruity and light, while spoiled oil will have a sharp, unpleasant odor.
- Cloudy Appearance: While some cloudiness is normal when the oil is refrigerated, persistent cloudiness or sediment floating in the oil could be a sign of bacterial growth.
- Mold: If you see mold inside the bottle or on the surface of the oil, discard it immediately.
- Change in Taste: Spoiled oil will have a bitter or off taste, which is a clear indication that it’s no longer safe to consume.
If you observe any of these indicators, it’s advisable to discard the oil. For tips on how to safely dispose of spoiled oil, refer to this article.
Can You Freeze Garlic-Infused Olive Oil?
Freezing garlic-infused olive oil is an option if you want to extend its shelf life even further. Freezing will not harm the oil, but it can alter its texture slightly. Here are some tips for freezing:
- Use Small Containers: Portion the oil into smaller containers to make it easier to thaw only what you need.
- Thaw at Room Temperature: Avoid microwaving the oil to thaw it, as this can alter its flavor. Instead, let it come to room temperature naturally.
- Do Not Refreeze: Once thawed, it’s best to use the oil within a few days.
Freezing is particularly useful if you make large batches of infused oils and want to preserve them for several months.
How to Make Garlic-Infused Olive Oil Safely
Making garlic-infused olive oil at home is relatively simple, but it’s crucial to follow safety precautions to reduce the risk of bacterial growth. Here’s how you can make your own safely:
- Sterilize the Containers: Before you begin, make sure your jars or bottles are thoroughly sterilized to prevent contamination.
- Heat the Oil: Gently heat the olive oil to about 180°F (82°C) to help kill any potential bacteria on the garlic cloves.
- Infuse the Oil: Add fresh or roasted garlic to the heated oil and let it steep for about 30 minutes to an hour. Avoid leaving the garlic in the oil for too long, as it increases the risk of spoilage.
- Strain the Garlic: Once infused, strain the garlic cloves from the oil and store the oil in a dark, airtight container.
- Refrigerate Immediately: To ensure the oil lasts as long as possible, refrigerate it immediately after preparing.
Following these steps will help reduce the risk of botulism and keep your garlic-infused oil fresh and flavorful for longer.

How to Dispose of Spoiled Garlic-Infused Olive Oil
If your garlic-infused olive oil has gone bad, it’s important to dispose of it properly:
- Do Not Pour It Down the Drain: Pouring oil down the drain can clog pipes and cause plumbing issues. Instead, place it in a sealed container and throw it in the trash.
- Use Absorbent Materials: If you want to throw the oil away, you can soak it up with absorbent materials like paper towels or coffee grounds before placing it in the garbage.
Frequently Asked Questions (FAQs)
Can You Leave Garlic in Olive Oil?
No, it’s not recommended to leave garlic in olive oil for extended periods, as this creates a perfect environment for bacteria like Clostridium botulinum to grow. Always strain the garlic out after infusing the oil.
What Happens If You Consume Expired?
Consuming expired garlic-infused olive oil can lead to foodborne illnesses, including botulism. If the oil smells rancid or looks cloudy, discard it immediately.
How Long Does Garlic-Infused Olive Oil Last in the Refrigerator?
Garlic-infused olive oil can last for up to 6 months when refrigerated, but it will solidify. To use, simply allow it to warm up at room temperature before serving.
Conclusion
Is a flavorful and versatile addition to many dishes, but it comes with a shorter shelf life than plain olive oil. By following proper storage techniques, regularly checking for signs of spoilage, and being mindful of safety precautions when making it at home, you can enjoy garlic-infused olive oil safely and deliciously for months.
