There are countless ways to prepare porterhouse steak, and it turns out just as delicious with each and every one of them.

And if you’ve cooked a little too much of it than you and the members of your household can eat in a single meal, which is probably the case since you’re reading this article, you can always put the cooked porterhouse steak in the fridge or freezer and save it for later.

But you may be wondering, exactly how do you store cooked porterhouse steak? And by when should you and the family eat it all up?

For the answers to these questions and the ones you didn’t know you had to ask, read on below!

How Long Does Cooked Porterhouse Steak Last?

The key thing to know is that the bacteria that make porterhouse steak spoil and cause food poisoning for those who eat it thrive at room temperature, multiply slowly in the fridge, and go into pause in the freezer.

This is why cooked porterhouse steak can only be left out and kept in the fridge for so long. Technically, frozen food stays safe to eat forever.

But its texture, aroma, and taste degrade the longer you store it, so you shouldn’t wait too long to thaw, reheat, and serve it on the dining table.

As a general rule, cooked porterhouse steak keeps for 1-2 hours at room temperature and 3-4 days in the fridge. Although the food in your freezer stays safe to eat indefinitely at 0°F (-18°C)¹, frozen cooked porterhouse steak only retains its best quality for 1-3 months, after which it begins to dry out and lose flavor.²

Can You Eat Old Cooked Porterhouse Steak?

Don’t eat cooked porterhouse steak that’s been on the kitchen counter or dining room table for more than 2 hours, or that you’ve kept in the refrigerator for more than 4 days. If you do, you may get food poisoning.

Even if the porterhouse steak looks, smells, and tastes fine, don’t eat it; this is no guarantee that it’s safe to eat. Not everyone knows that the bacteria that make cooked porterhouse steak (and all other foods) spoil are not the same as the pathogens that cause foodborne illness.³

In other words, cooked porterhouse steak that seems perfectly fine may still be overgrown with disease-causing bacteria. If the porterhouse steak is too old, discard it.

Try as you might, but is impossible to determine whether or not it’s safe to eat in the confines of your home, without laboratory equipment.⁴

Will Heating Old Cooked Porterhouse Steak Make It Safe to Eat?

Let’s talk about a dangerous misconception that many of us have about the food that we eat.

Reheating, recooking, or incorporating old cooked porterhouse steak into another dish won’t make it any safer to eat. (And this rule applies not just to porterhouse steak, but to all red meat as a whole.)

Exposure to heat does eliminate the pathogenic bacteria on the cooked porterhouse steak. However, those bacteria may have left heat-resistant spores and toxins behind on the flesh, which can just as well cause food poisoning.

To protect yourself and those you cook for from food poisoning, discard cooked porterhouse steak if you suspect that it’s too old to still be safe to eat, especially now that you know how old is too old.

How to Store Leftover Cooked Porterhouse Steak

Never leave leftover cooked porterhouse steak at room temperature for more than 2 hours, whether on the kitchen countertop or the dining room table. (In the summer, when it’s 90°F/32°C or hotter outside, this time is reduced to only 1 hour.)

Allow the leftover cooked porterhouse steak to cool down, then refrigerate it for storage of up to 4 days or freeze it for long-term storage (properly stored in the freezer, cooked porterhouse steak keeps its best texture, aroma, and flavor for no longer than 3 months).

Contrary to what many people think, warm or even hot porterhouse steak can be placed directly in the refrigerator. However, it’s better for the rest of the food in your fridge if you first chill it in cold water or an ice water bath, especially if you just took it off the heat.

Before refrigeration or freezing, seal the porterhouse steak in ziplock bags or food storage containers with the lid closed. Some people will wrap theirs in aluminum foil or butcher paper instead, although it’s worth keeping in mind that loosely wrapped porterhouse steak can get damaged by freezer burn in the freezer.

The Takeaways: Cooked Porterhouse Steak’s Shelf Life

Depending on the storage method, cooked porterhouse steak keeps:

For 1-2 hours when left out on the kitchen countertop or dining room table
For 3-4 days when stored in a ziplock bag or food storage container and refrigerated
Indefinitely when frozen, although it only retains its best quality for 1-3 months

When in doubt, follow food safety rule #1 and throw it out. Remember that spoilage bacteria and disease-causing bacteria are not the same thing, and cooked porterhouse steak that hasn’t yet spoiled can still be unsafe to eat.
