Butter is one of those staples worth buying extra of when it's on sale, since it's used in nearly everything — and unlike a lot of dairy, it barely notices being frozen.
The main risk isn't the butter itself; it's the freezer around it. Butter absorbs odors easily, so how you wrap it matters more than how long you freeze it.
Freeze butter in its original packaging and place it inside a freezer bag for extra protection. Smaller portions are convenient if you use butter slowly.
Butter keeps its quality very well in the freezer for months. Proper wrapping helps it stay fresh and avoid absorbing odors.
Thawed butter usually behaves much like fresh butter. It can be spread, baked with, or melted as usual.
Butter is about as freezer-friendly as food gets. Wrap it tightly, and it will taste and perform almost exactly like fresh months later.
Both freeze well, but salted butter tends to hold its quality a bit longer since salt has a mild preservative effect.
Yes, many recipes call for frozen butter grated straight into dough, which helps create a flakier texture in pastries and biscuits.
Butter absorbs surrounding odors quickly. A tight wrap or sealed bag on top of the original packaging keeps other freezer smells out.
