Should peanut butter be kept in the fridge, or can it stay in the pantry?

The debate over whether to store peanut butter in the fridge or pantry depends largely on the type of peanut butter you use. Processed peanut butters, which often contain added oils, sugar, and preservatives, are best kept in the pantry. This storage method maintains their soft texture, making them easy to spread, and allows for convenient access. They typically last several months after opening.
On the other hand, natural peanut butter, made with just peanuts and salt, is more prone to spoilage and oil separation when left at room temperature. Refrigeration is recommended for natural varieties, as it helps extend shelf life and preserves flavor. However, it can harden the texture, making it harder to spread right out of the fridge.
Ultimately, the choice between fridge and pantry storage hinges on personal preference and the type of peanut butter. Processed options thrive in the pantry, while natural varieties benefit from the fridge’s cool environment to stay fresh longer.
