Should you refrigerate coconut oil?

Coconut oil has become a popular cooking and baking oil in recent years due to its health benefits and versatile uses. With its growing popularity, there has been some debate over whether or not coconut oil needs to be refrigerated. Here is a comprehensive look at whether you should keep coconut oil in the fridge.

What is coconut oil?

Coconut oil is extracted from the meat of mature coconuts. It is very high in saturated fats, with around 90% of its fat content coming from saturated fats. The main type of saturated fat in coconut oil is lauric acid, which has antibacterial and antimicrobial properties. Coconut oil also contains medium-chain triglycerides (MCTs), which are metabolized differently than most other fats and provide an efficient energy source.

Unrefined or virgin coconut oil is extracted from fresh coconut meat without the use of high temperatures or chemicals. This helps preserve more of the natural phytonutrients and antioxidant compounds found in coconuts. Refined coconut oil goes through more processing, including bleaching and deodorizing. This helps remove impurities and results in a neutral scent and flavor profile.

Does coconut oil need to be refrigerated?

In general, there is no need to store coconut oil in the refrigerator. Here are some key reasons why coconut oil can be safely kept at room temperature:

  • High saturated fat content – The high percentage of saturated fats in coconut oil gives it a very stable shelf life compared to other oils. Saturated fats are less prone to oxidization and rancidity.
  • High melting point – Coconut oil is solid below 76°F (24°C). Its high melting point keeps it from going rancid at room temperature.
  • Long shelf life – Unopened coconut oil has a shelf life of 2-5 years at room temperature. The saturated fats help prevent spoilage.
  • Antioxidant content – Compounds like polyphenols and vitamin E in virgin coconut oil act as antioxidants, further preventing rancidity.

The stability of coconut oil gives it a much longer shelf life than other oils. As long as it is stored properly in an airtight container away from heat and light, coconut oil can safely be kept at room temperature for everyday use.

When to refrigerate coconut oil

While refrigeration is not required, some instances when you may want to keep coconut oil in the fridge include:

  • Prolonging shelf life – Refrigeration can help extend the shelf life of coconut oil from 2-5 years to up to 10 years.
  • Hot climates – If living in hot conditions over 90°F (32°C), refrigeration can prevent oil separating.
  • Large batches – When buying in bulk, refrigerate what you won’t use within a couple months.
  • Virgin coconut oil – Unrefined coconut oil is more prone to rancidity than refined varieties.

The bottom line is that while refrigeration can prolong shelf life, it is not essential for coconut oil storage. Many people successfully keep coconut oil in the pantry.

Does cold impact coconut oil?

The one downside of refrigerating coconut oil is that it will become solid and harden at cold temperatures. The fatty acids in coconut oil can crystallize and take on a grainy, crumbly texture when stored below room temperature. This doesn’t detrimentally affect the coconut oil, but it does make scooping and measuring more difficult.

To avoid the hassles of hardened coconut oil, you have a couple options:

  • Freeze in smaller batches – Store coconut oil in ice cube trays or silicone molds.
  • Thaw before use – Take out what you need and let it come to room temperature.
  • Use a spoon – The hardness makes it tricky to pour melted.

The change in texture is only temporary. Coconut oil will quickly return to liquid form once at room temperature. The solid state does not damage the oil or make it unsafe to use.

How to store coconut oil

To maximize the shelf life of coconut oil, follow these tips for proper storage:

  • Airtight containers – Store in containers with tight lids to block oxygen exposure.
  • Dark cabinets – Keep coconut oil away from light to prevent oxidization.
  • Cool area – Avoid warm spots like near the oven that can melt or spoil oil.
  • Organize kitchen – Use oldest coconut oil first and check expiration dates.
  • No plastic – Don’t store in plastic containers which can leach chemicals.

Glass jars, metal tins, or opaque plastic containers work best for coconut oil storage. Be sure to keep it sealed and away from heat, moisture, and sunlight. With proper storage methods, coconut oil can retain quality and freshness for years.

Signs coconut oil has gone bad

Coconut oil has a long shelf life, but it can eventually spoil. Signs your coconut oil has gone rancid or bad include:

  • Change in color – Oil turns from white/clear to yellow or orange.
  • Change in smell – Rancid coconut oil smells “off” instead of sweet and nutty.
  • Change in taste – Oil tastes bitter or unpleasant instead of mild and coconutty.
  • Mold – Visible mold may grow if water is introduced.
  • Texture change – Liquid oil becomes gritty and develops clumps.

Coconut oil does not typically need refrigeration, but rancidity can still occur over time. Use your senses of sight, smell, and taste to check for any indicators the oil has spoiled before use.

How long does coconut oil last?

Here is an overview of how long properly stored coconut oil lasts:

Storage Method Shelf Life
Room temperature (unopened) 2-5 years
Pantry (opened) 6-12 months
Refrigerator (opened) 2-3 years
Freezer (opened) Indefinite

The shelf life of coconut oil depends on storage conditions and whether it is opened or not. Refrigerating and freezing can prolong its stability once opened. But coconut oil can also last at cool room temperature for everyday use.

How to tell if coconut oil is bad?

Coconut oil does not always have signs of spoilage when it has gone bad. Rancid coconut oil beyond its prime may have no change in color, smell, or texture. There are a few ways to test coconut oil freshness and quality:

  • Melting test – Quality coconut oil melts quickly at 76°F into a clear liquid.
  • Refrigeration test – Oil that hardens at fridge temps and liquefies when warmed is fresh.
  • Smoking point test – Lightly heat a small amount. Fresh oil has a high smoke point of 350°F.
  • Filtration test – Passing oil through a fine filter checks for particles.

If you are ever unsure how old your coconut oil is or if it is rancid, try one of these simple freshness tests. This can give you added peace of mind that your coconut oil is safe to cook and bake with.

Can you restore spoiled coconut oil?

Unfortunately, once coconut oil has gone rancid or spoiled it cannot be safely restored. The oxidation cannot be reversed. Any odors, flavors, and microbes that develop can persist even if you try reheating or filtering the oil.

You will need to dispose of rancid coconut oil properly. Place it into an airtight bag or container and put in the trash. Rancid oils can go rancid faster, so dispose of it quickly to avoid spreading the issue.

Can you eat expired coconut oil?

It is not recommended to eat coconut oil past its expiration date. However, coconut oil’s long shelf life means an expiration date may just indicate best quality rather than spoilage. Smell expired coconut oil before use – if it retains a fresh coconut aroma with no rancidity, it is likely still safe to consume.

If refrigerated and unopened, coconut oil can often be safely used for up to a year past expiration. But toss if you notice any odd odors, flavors, appearance, or texture.

Cooking and baking with coconut oil

Refrigeration is not needed for everyday cooking and baking with coconut oil. Here are some usage tips:

  • Measure out only what is needed so you aren’t continually warming and cooling the batch.
  • Scoop solid coconut oil into measuring spoon and level off for accuracy.
  • Quickly rinse measuring spoons and cups with hot water if oil solidifies.
  • Avoid freezing recipes with coconut oil as it will harden and separate.
  • Reduce oven temperature 25°F if using coconut oil in place of other oils.

Coconut oil brings a nice light coconut flavor to recipes. It performs well at high heats, making it a good choice for sautéing and stir-frying. Always select fresh, non-rancid coconut oil for the best results and health benefits.

Other oils that don’t need refrigeration

Like coconut oil, some other cooking oils can be safely stored at cool room temperature. Oils with higher saturated fat contents tend to be more shelf-stable. Other oils that can be kept in the pantry include:

  • Olive oil – Extra-virgin and virgin olive oil can be stored in a cool pantry up to 2 years.
  • Avocado oil – Its high monounsaturated fat provides up to 6 months shelf life opened.
  • Palm oil – Refined palm oil can last over a year unopened at room temperature.
  • Nut oils – Unopened, cold-pressed nut oils can have a shelf life up to a year.

Always follow best practices like using airtight containers and keeping oils out of sunlight and heat. An opened bottle of oil may only last a month or two – so refrigerate extras to maximize freshness.


Coconut oil has a natural long shelf life due to its stability. There is no need to keep coconut oil refrigerated for daily kitchen use. Storing coconut oil at cool room temperature is safe and convenient.

Refrigeration can help prolong the shelf life of coconut oil further once opened. But proper storage methods allow coconut oil to last for up to 2-5 years when kept in a pantry or cupboard. Check for signs of spoilage and rancidity before use. Keep coconut oil fresher for longer by buying in smaller batches, using airtight storage, keeping out of heat and light, and being mindful of expiration dates.
