How Long Can Corned Beef Sit Out? [Cooked Vs. Uncooked Varieties]

Corned beef and cabbage is a dish that is more synonymous with Irish-Americans than with Ireland itself.

This cut of meat is typically served around St. Patrick’s Day, and it’s used to make a delicious hash. So, how long can this cured meat sit out at room temperature before going bad?

Corned beef, like all cooked meats, should not be left out at room temperature for extended periods. According to food safety guidelines, corned beef should not sit out for more than 2 hours, or 1 hour in temperatures above 90°F, to prevent the growth of harmful bacteria. If the corned beef has been sitting out beyond these time frames, it’s best to discard it to avoid the risk of foodborne illness. To preserve leftover corned beef, it should be refrigerated promptly and consumed within 3-4 days, or it can be frozen for up to 2 months.

What Is Corned Beef?

When first hearing of this dish, your mind might have gone directly to corn. While our favorite yellow veggie is deliciously roasted, it has nothing to do with corned beef.

Did You Know?

The term “corned beef” refers to a specific cut of meat cured with salt the size of the kernels. That’s where it gets the name. 

This style of cooking was invented in Ireland, but they rarely used beef. Cows were sacred and used in the fields.

Still, the Irish would salt their meat with “sea ash” for preservation. We have refrigerators now, but before they were invented, people had to use other methods. 

Corned Beef

Corned beef refers specifically to a specific cut of meat, which is brisket. This staple was perfected by Irish immigrants in the North Eastern region of the United States.

The brisket was inexpensive, and the immigrant used methods familiar to their culture. And the St. Patrick’s Day staple was created.

How Is Corned Beef Made?

To make corned beef from scratch, you need a brisket, a ton of seasonings, and at least a week and a half.

Corned beef requires creating a brine and letting your brisket soak in the fridge. 

Brine Recipe

To mix a brine, you need the following ingredients. 

1 gallon of water

1 cup kosher salt

3 tbsp pickling spices

½ cup brown sugar

Mix it all in a pot and bring it to a boil. Then let the brine cool to room temperature. Put your brine in the fridge and let it cool until it’s cold. 

Corned Beef Recipe

5 lb beef brisket

1 tbsp pickling spice

Submerge your brisket in the brine. It must be covered, so you may need to weigh it down.

Cover it tightly and let it sit in the fridge for five to seven days. You should mix the brine and turn the meat every day. 

After the seventh day, take your brisket out and rinse it well with cold water. Then put it in your roasting pan or crockpot and let it simmer on low for eight hours.

You’ll know when the corned beef is done because it will separate with a fork. 

Take it out of the crockpot and let it rest on the cutting board. You can use the leftover liquid for simmering cabbage. 

How Long Can Corned Beef Stay In The Fridge Before Cooking?

There are mixed opinions on this subject. Alton Brown of the Food Network says to let it soak for ten days.

But the University of Minnesota` says it’s good for five to seven days. If you’re creating the brine yourself, it’s best to follow the recipe instructions.

If you’ve purchased an uncooked corned beef in brine, follow the package instructions. 

Store-Bought vs. Homemade

You can skip many steps if you purchase an uncooked corned beef already soaking in a brine.

Consumers can find sealed packages of corned beef soaking in the meat section of the grocery store. 

Which is better? Well, we always advocate for homemade. When making your brine, you can tweak the seasonings and create a flavor you love.

But, purchasing one already soaking is a way to avoid some hard work. The store-bought brands are usually delicious and require less hassle. 

There are also corned beef options in the deli that have already been cooked. All you need to do is grab a number or find a package in the refrigerated section.

Purchasing corned beef that’s already prepared is a great way to get a fast Irish meal. 

Corned Beef

All corned beef can become the playground for harmful bacteria if left out of the fridge for longer than 2 hours.

If you left the meat sitting out, it doesn’t matter what stage of preparation. You should throw it away and avoid any possible foodborne illness. 

How Long Cooked Corned Beef Last In The Fridge?

Sometimes you cook the corned beef too soon and need to store it. Other times you’ve made more than you need and want to keep it.

We all know the best place for storing this delicious meat is in the fridge. Once you have your leftovers in the refrigerator, you have three to four days. 

Food that sits in the refrigerator is still at risk for contracting harmful bacteria. The bacteria grows in cooler temps but not as fast.

That’s why it takes days for the bacteria to multiply. Even if you have your corned beef in airtight, shallow containers, you shouldn’t eat it after four days. 

Corned Beef Hash Recipe

Creating hash with corned beef is one of the tastiest ways to use up your leftovers. It’s simple, and you can use one pan, which means less clean-up. 


1 lb corned beef diced

1 lb potatoes

One large white onion diced

Three cloves garlic diced

3-4 tbsp butter

Salt and pepper

First, parboil your potatoes. Bring a pot of water to a boil. Add your whole, washed potatoes.

Once you can pierce them easily with a steak knife, pull them out. Let the potatoes cool. When your potatoes are cool, dice them. Now it’s time to make your hash. 

Take a pan and add your butter. Keep the flame on medium and add your onion. Let that cook for two minutes and add the garlic.

Let that cook for another minute and add your potatoes. Let the potatoes cook until they’re starting to get brown. Then add your corned beef. Let it all fry until it’s the crispiness you desire. 

Serve with a sunnyside egg on top and toast.

Corned Beef Hash Store-Bought vs. Homemade

Don’t want to go through the trouble of making your hash? That’s okay. Cans of premade hash are typically available at the store.

While we love home cooking, a can of Hormel corned beef hash is delicious, especially when fried to a crisp. 

When it comes to storage, there is no difference. Homemade corned beef hash and the canned version are only good at room temperature for 2 hours.

Once they go past that point, they move into the dreaded Danger Zone, where bacteria multiply rapidly. 

The best place to store corned beef is in the refrigerator. The same goes for hash. Leftovers of all kinds are best stored in airtight containers.

Corned beef and corned beef hash are good in the fridge for two to four days. If you’ve gone longer than four days, we suggest throwing it away.

While none of us likes to waste food, the bacteria that cause foodborne illnesses can be severe. Food poisoning can lead to abdominal pains, dehydration, and even hospitalization.
