Keep it on a middle shelf, not the door: the door warms up every time it opens.
Butter shelf life, answered
How long does butter last in the fridge?
1–2 months at 4°C (40°F) or colder. Keep it sealed so it does not pick up moisture or odours.
How long does butter last in the freezer?
6–9 months for best quality at -18°C (0°F). Frozen food stays safe indefinitely; after that, texture and flavour fade.
How long does butter last at room temperature?
It is not meant to be kept at room temperature. Refrigerate it.
How long is butter good for past the expiration date?
Butter past its best-by date is usually safe if stored well; check smell, look and taste before using.
How can you tell if butter is bad?
Rancid: like crayons, paint or old nuts. Bitter or soapy aftertaste. Sticky or gummy residue around the lid.
Signs butter has gone bad
Smell
Rancid: like crayons, paint or old nuts.
Taste
Bitter or soapy aftertaste.
Texture
Sticky or gummy residue around the lid.

Can you freeze butter?
- 1Step 1
Freeze in an airtight container or the original sealed pack.
- 2Step 2
Portion first (cubes or small jars) so you thaw only what you need.
- 3Step 3
Thaw in the fridge; fats and nuts can be used straight from frozen.
How to thaw butter
In the fridge
Move it to the fridge the night before; texture holds best.
At room temperature
Only for shelf-stable foods; perishable food should not thaw on the counter.
From frozen
Many foods go straight into soups, sauces, smoothies or the oven.
Butter left out overnight
Butter is not a high-risk food, but a night out shortens its fridge life. Refrigerate it and use soon.
Best-by and use-by dates on butter
Best-by and sell-by
FoodKeeper gives unopened butter 1–2 months in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Past the date
Butter past its best-by date is usually safe if stored well; check smell, look and taste before using.
How to store butter
- May be left at room temperature for 1 - 2 days.
- Keep in a cool, dark place, tightly closed, away from heat.
- Refrigerating nuts, seeds and nut oils extends shelf life significantly.
- Smell before using; rancidity is a quality problem you can detect.
