Land O'Lakes finally settles the debate: How long can you leave butter out on the counter?

When it comes to storing food, many of us follow the practices our parents and grandparents used. Who cares about reading the package instructions when Grandma left her butter in the butter bell all day, every day, right?

So, maybe your butter's home is on the counter in a dish. Or if not on the counter at all times, perhaps you leave your butter sitting out overnight to soften before baking.

But, should you leave butter sitting out, unrefrigerated? And, if so, how long can it be on the counter before it becomes unsafe to eat? We asked the experts at Land O'Lakes to put the debate to rest once and for all—and some of you might not like the answer......

Even though room-temperature butter likely won't make you sick, Land O'Lakes recommends storing butter in the fridge when you're not using it. But, if you're in the heat of baking and forget to put the last little knob back in the fridge right away, that's ok—just so long as you don't let it sit out for a few extra hours.

"Do not leave butter at room temperature for more than 4 hours," says Engen. "Always return any unused butter to the refrigerator and be aware that butter left outside refrigeration may become darker in color and have [its] flavor affected."

Keeping butter in the fridge is a good rule of thumb, as it helps ensure the tasty fat won’t pick up any undesirable odors or flavors from your kitchen. Plus, the cool fridge temps make butter last much longer because room-temperature butter can go rancid within a day or two, according to the USDA, while refrigerated or frozen butter can last months.

Eric Swalwell doesn’t worry about such things

I buy butter in a small tub & if I don’t leave it out, I can’t spread it. It is alway covered. Unused containers are kept sealed & refrigerated until ready to use, tho. Haven’t had any health problems with it so far & this includes several years.

If you pay attention to “Granny Warren” then you best change your ways.

I just buy the half-stick packages of Land O' Lakes. That way, if any one stick sits out for awhile, it's going to get used quickly and then I can just take another half-stick out of the box.

I agree, the thing is Land o Lakes introduces the thought, you wouldn’t want your buttr to have you serve lower qulity foods to your friends or family would you ?

Last year I left half a stick of Kerry Gold out in a covered butter dish.

Nice rug there, Bill.

Sorry for the misunderstanding, meant to be a joke.

Lasts for weeks at room temperature.

We leave our butter out in the pantry, and put our bananas in the refrigerator.

Mrs. Alaska just bought 6.5 pounds of bananas at our local Giant Eagle for 99 cents, we ate two and the rest went into the fridge.

Yea, the skins will turn black, but we can eat two a day for more than 10 days and they will be fine.

The butter has never gone rancid, but we've only had 63 years of experience, so the jury is still out...

Did you ever fold the Indian lady’s knees up?

Yep, kitty c-nt.

You have a creative mind:)

Also “natural flavorings.”

Meaning unnamed chemicals.

No thanks.

[ImJustAnotherOkie]

You can keep your natural flavorings like that natural flavoring they put on hamburger you thought was mayo.

[right way right]

Butter taste does deteriorate a bit when sitting room temp.
It does not last long enough on my counter top to matter.

Just for the record, butter has existed for untold eons before refrigeration existed.

One of the reasons for making and having butter is that it preserves the beneficial milk products without refrigeration

[HamiltonJay]

Nope, not at all...

If you buy the UNSALTED yes, it says Sweat Cream and Natural Flavorings, because they are not using salt in the butter.

If you are buying Land O Lakes Salted Butter, the ingredients list is simply “Sweat Cream and Salt”, period.

And if you want to know what that “natural flavoring” is, its simply lactic acid, which is added so the butter doesn’t spoil. Salt naturally preserves food, and causes it to last longer. Unsalted butter does not obviously have this, so they add lactic acid in its place.

So in terms of “chemicals”, don’t ever use your muscles or exercise, because your body makes lactic acid when you do, and bacteria produce this during fermentation.. so don’t drink any beer or wine, or eat any baked goods, especially sour dough if you are worried about it consuming it or having it in your body.

As I said, people are idiots.

[Right_Wing_Madman]

What!!?? Cream and salt. What ingredient lists are you guys reading??

Butter is one of the great luxuries of life.

Do yourself a favor. Eat a slice of toasted sour dough bread topped with Land O'Lakes butter and another slice of toasted bread with Kerrygold butter. You'll be angry at yourself for wasting all these years eating crap butter.
