How Long Does Homemade Chili Oil Last?

If you make your own chili oil at home, you might wonder how long you can keep it before it goes bad. The answer depends on several factors, such as the type of oil, the freshness of the ingredients, the sterilization of the jars, and the storage conditions. In general, homemade chili oil can last for up to six months if stored properly. However, it is best to use it within three months for optimal flavor and quality.

To make your homemade chili oil last longer, follow these tips:

Use a high-quality oil with a long shelf life, such as canola, sunflower, or peanut oil.
Use fresh and dry chili peppers, garlic, ginger, and other spices. Avoid using moldy, bruised, or wilted ingredients.

Sterilize the jars and lids before filling them with chili oil. You can do this by boiling them in water for 10 minutes or baking them in the oven for 15 minutes at 135° C (275°F).
Fill the jars with chili oil while still hot and seal them tightly. This will create a vacuum that prevents air and bacteria from entering.
Store the jars in a cool, dark, and dry place, away from direct sunlight and heat sources. You can also refrigerate them to extend their shelf life.

Note that it is also possible to store your oil in small bottles. Obviously, you should sterilize the bottles before adding your chili oil to them.

How Long Does Chili Oil Last Unrefrigerated?

If you buy chili oil from the store, you might notice that some brands say “refrigerate after opening” while others do not. This is because different brands use different preservatives and additives that affect the shelf life of chili oil. In general, chili oil that contains vinegar, salt, sugar, or citric acid can last longer than chili oil that does not. These ingredients act as natural preservatives that inhibit the growth of bacteria and mold.

However, even if your chili oil does not require refrigeration, you should still store it properly to prevent it from going rancid or losing its flavor. Here are some tips on how to store chili oil unrefrigerated:

Keep the bottle tightly closed when not in use. This will prevent oxygen and moisture from entering and spoiling the oil.
Store the bottle in a cool, dark, and dry place, away from direct sunlight and heat sources. Exposure to light and heat can cause the oil to oxidize and degrade.

Use a clean spoon or dropper to dispense the chili oil. Avoid contaminating the oil with food particles or saliva, which can introduce bacteria and mold.
Use the chili oil within the expiration date printed on the bottle. If there is no date, use it within six months of opening.

How Long Does Chili Oil Last in the Fridge?

If you want to extend the shelf life of your chili oil, you can store it in the refrigerator. This will slow down the oxidation and deterioration of the oil and keep it fresher for longer. However, refrigerating chili oil can also affect its texture and flavor. When chilled, you might notice the oil becoming cloudy, thick, or solidified. This is normal and does not mean that the oil has gone bad. It will return to its original state when brought to room temperature.

Here are some tips on how to store chili oil in the fridge:

Transfer the chili oil to a glass or plastic container with a tight-fitting lid. This will prevent the oil from absorbing any odors or flavors from other foods in the fridge.
Label the container with the date of opening and the expiration date. This will help you track how long the oil has been stored and when to use it.

Let the chili oil come to room temperature before using it. This will restore its fluidity and flavor. You can also microwave it for a few seconds or place it in a bowl of warm water to speed up the process.
Shake or stir the chili oil before using it. This will help distribute the spices and seasonings evenly throughout the oil.

Store-bought chili oil can last for up to six months, unrefrigerated, if stored in a cool, dark, and dry place. It can last longer with preservatives such as vinegar, salt, sugar, or citric acid.

Refrigerating chili oil can extend its shelf life but also affect its texture and flavor. Let it come to room temperature before using it, and shake or stir it well.
