Can Peanut Oil Go Bad?
Peanut oil has a reasonably long shelf life but it won’t keep forever. As with most types of cooking oil, peanut oil will keep well in storage for months. This goes especially for unopened bottles of peanut oil. That being said, the shelf life of the product becomes shorter once the container has been opened.
Peanut oil has a clean taste so it can be reused several times. But reused peanut oil has a shorter shelf life than fresh peanut oil. However, as long as the oil has been stored properly, there is no need to worry about spoilage at all.
Signs that Peanut Oil Has Gone Bad
It’s quite easy to tell if peanut oil has gone bad, just check the clarity, color, and smell of the oil. If the oil has turned a deeper shade of brown or it starts emitting an unpleasant odor, it is no longer safe to use. If the product has turned cloudy or the fats started breaking down, toss the product in the trash.
How to Store Peanut Oil?
The pantry is the best place to store sealed and/or freshly opened bottles of peanut oil. Keep the product in a cool, dark place away from sources of heat and light to extend the oil’s shelf life. Peanut oil is quite sensitive to heat and direct sunlight. Unstable temperature could cause the product to spoil much more quickly. Avoid storing the oil near the stove or other appliances that heat up while in use.

When kept in the pantry, sealed bottles of peanut oil will keep for 3 years. On the other hand, opened bottles of peanut oil will keep in the pantry for a year or so.
As for peanut oil that’s nearing its expiry date, you can store the oil in the fridge. Of course, the peanut oil will solidify and turn cloudy when stored in the fridge but it’s still safe to use. There won’t be any changes in flavor or aroma once the refrigerated oil is used in cooking. Peanut oil kept in the fridge will stay fresh for 3 to 4 years.
