Yes, but not for very long if you are planning on eating it later. Put your pasta sauce in a metal container right after dinner and "force cool" it in the sink by surrounding the pan with cold water. This will sink a lot of the heat out so you don't "heat load" your fridge by placing hot food in it. Then transfer the cooler food into an appropriate container and get it in the fridge. You can leave the pan in the sink in water to cool the sauce for an hour or so without any risk. Just stir it once in a while, and perhaps change the water once. Get it cooled down to "room temperature" or so, then move it to the chiller. You'll use your best judgment about "water waste" and "energy waste" when doing the cooling.
Bon appétit.
Foods that are left out in room temperature for more than an hour can begin bacteria growth. Our stomach acids can kill some of these bacterias but not all and some can make you very sick. Keep foods OUT of the danger zone- Above 45 degrees and Below 145 degrees. Between these temperatures bacteria lives and breeds on our foods.
A long time - if you're not planning on eating it. You won't want to leave it out more than an hour or two to cool, then put it in an appropriate container and into the chiller. The lack of meat in pasta sauce will probably allow you more latitude as regards leaving it out, but not much. Don't push your luck. Leave any sauce out a hour or so in the coolest place you can, and then get it into a container and into cold storage. (It's not a good idea to put hot food in a fridge.) You'll have some 3 to 5 days or so to enjoy it. Bon appétit.
About a week
about five decades
A few months
Until it is just warm, then it should be refrigerated.
about 12 to 18 months
it is at least 5 and a half inches long
i would say about a week.
About four to five days, properly refrigerated.
The pasta is usually with the pasta in any grocery store. The sauce is with canned goods/sauces & most use ground beef for the meatballs.
At least 3 days[ put garlic on for better results]
"Spaghetti" actually refers to the shape of the pasta, and in the US "marinara" refers to the sauce. You can use whatever sauce you want on spaghetti, but it's best suited to lighter sauces with not a lot of big chunks, like a simple drizzle of olive oil and crushed garlic, or a carbonara. "Spaghetti" is actually plural for "spaghetto" which translates to "twine" in Italian. In Italy you would say the type of pasta and then mention the sauce too. So the classic spaghetti dish we know in the US would be called "Spaghetti alla marinara".
The time it takes to heat up spaghetti sauce depends on the method used and the starting temperature. Typically, it takes about 5-10 minutes to heat up spaghetti sauce on the stovetop, stirring occasionally to prevent burning. Microwave heating may take a bit less time, around 2-3 minutes.
