It’s so easy to cook too much pasta when making dinner — who really knows how to properly measure how much spaghetti to cook per person?

When you’ve cooked too much pasta and you’re busy enjoying your meal while the pasta sits out, there is a good chance that it could get sticky, or even go bad.

So, how long can pasta sit out before getting sticky or going bad? Pasta should not be left out at room temperature for longer than 2 hours. After 2 hours, there is a good chance that the pasta will either become sticky or could start to go bad — either way, you won’t want to eat it!

So, if you are in the habit of leaving pasta out in the kitchen for some time before putting it away, read on to find out how long it can stay out (and more) to ensure that your pasta never goes to waste!

How Long Can Pasta Without Sauce Sit At Room Temperature Before Getting Sticky?

You might think that plain pasta without sauce can be left out at room temperature for longer than pasta that has sauce, but this definitely is not true.

The FDA recommends that no food should be left out at room temperature for longer than two hours, as the risk of bacteria growth increases after this time.

The danger with cooked pasta is that it can harbor bacillus cereus, which is a heat-resistant bacteria that germinates as the pasta cools down.

As it is heat-resistant, this bacteria will not be killed when you reheat the pasta, and there is a very good chance it can make you sick.

Other than worrying about bacteria growth on your pasta, pasta that is left out at room temperature can turn sticky. This can happen after being left out for only half an hour. While it isn’t dangerous to eat, sticky pasta isn’t very appetizing.

So, if you do cook too much pasta, it is best to pack it away and place it in the fridge as soon as it cools down, to prevent it from turning bad.

How To Revive Sticky Pasta

There really can’t be anyone who enjoys eating sticky pasta, and unfortunately, pasta has a habit of turning sticky quite easily!

Once you drain pasta and put it aside, it can quickly glue together and form a bit of a sticky clump.

Not only is it difficult to eat sticky pasta, but it is difficult to serve it too, and it won’t hold a sauce well at all.

Luckily, there is a way that you can save sticky pasta, so it doesn’t all have to go to waste.

As soon as you notice your pasta turning sticky, put some water in a pot and allow it to come to a boil on the stove. Quickly dip the pasta into the boiling water, then add a tablespoon of oil or butter.

Drain the pasta again, and drizzle some olive oil over it to stop it from sticking together all over again.

If your pasta seems to always turn out sticky, it could be because it is lacking fat or moisture — try adding some oil or butter to the water the first time you cook the pasta.

Pasta, and pretty much any other food, should be left out at room temperature for no longer than two hours.

This goes for plain cooked pasta and pasta with sauce, as both are at risk of developing a large number of bacteria that could make you sick.

Bacteria are able to multiply rapidly between temperatures of 40-140°F, which is what room temperature falls into.

It is also important to note that bacteria multiply more rapidly the warmer it gets, so humid conditions at 90°F or warmer could spoil pasta much quicker.

It is advised that you pack pasta away, with or without sauce, in airtight containers as soon as it has cooled to room temperature, and that you do not leave it out for any longer than this.

Placing leftover cooked pasta in the fridge definitely extends its life somewhat, and it prevents it from spoiling quickly.

The best way to store pasta in the fridge is to try and separate the sauce and the pasta into their own airtight containers, then store them in the fridge.

The fridge should be below 40°F to prevent rapid bacterial growth.

When stored properly, pasta can be left in the fridge for three days. It might be fine for a day or so after this, but it is better not to risk it and rather throw it away.

A tip for storing pasta in the fridge, without any sauce, is to add a little bit of olive oil to the pasta before placing it in the container or sealable plastic bag (make sure to remove all the air from the sealable bag before closing it).

This will prevent the pasta from drying out and becoming sticky in the fridge!

As mentioned above, it is best to store pasta on its own in the fridge, but if it is already mixed together, you can store the pasta and the sauce together, either in a sealable food bag or an airtight container.

The problem with storing the two together is that the pasta can become mushy and not so pleasant to eat, but it also means that the pasta will absorb more flavor.

When storing pasta with sauce in the freezer, you should eat it within two days.

How Do You Reheat Leftover Pasta?

If you have some pasta leftover from the night before and you want to heat it up, you need to do so with some care to not dry the pasta out or cause it to become sticky.

To reheat pasta, it is best to use a pan on the stove.

You should add a small amount of olive oil or butter to the pan and place the pasta in the pan to heat up. You might need to add in a splash of water if the pasta is particularly dry.

You can also reheat pasta in the microwave, but this does run the risk of the pasta drying out — some butter or oil will help to keep it moist.

How To Tell If Pasta Has Gone Bad

It is always good to know how to tell if cooked pasta has gone bad, just to make sure that you are eating pasta that won’t make you sick!

Here are some of the signs to look for that pasta has gone bad.

Bad Odor

If you open up the container of pasta and get a bad odor, then it is likely that the pasta has gone bad. Fresh pasta should not have any rancid or off odors, and this is often the first sign that the pasta has gone bad.

Slimy Texture

Pasta can become sticky if it is left out for some time on the counter, but it should not be slimy.

If the pasta you have had stored in the fridge develops a slimy texture, then it is a good sign that it is on its way to spoiling, or that it has already spoiled.


Really old pasta can begin to develop mold — this could be small dark or white spots along the surface of the pasta. Do not try to just remove moldy spots, as there would likely be less-visible bacteria all over the pasta. 

Final Thoughts

Cooked pasta should not be left out at room temperature for longer than two hours.

Leaving it out for this time means that there is a high risk that there will be increased bacteria growth and that the pasta will become sticky.

To fix sticky pasta, you can dip it into boiling water with some oil or butter, and drain it again. A drizzle of olive oil will also help to fix it.

We are all guilty of cooking more pasta than what is needed (and sometimes cooking the pasta more than is needed), but make sure to pack it away in a fridge-safe container as soon as it reaches room temperature!

This will keep it fresh for up to three days in the fridge. Just make sure not to leave it out at room temperature for longer than two hours.
