As a rule, most if not all foods taste best when consumed fresh but with proper preservation, your Subway sandwich should taste just as good. In general, your subway sandwich should be able to retain its freshness for about three days comfortably in the refrigerator.
This begs the query “How long will subway sandwich last in fridge?”
In general, your subway sandwich should be able to retain its freshness for about three days comfortably in the refrigerator. Even if there is the possibility that they could go for longer, it would be risky to consume a subway sandwich that has sat in the fridge longer than three days despite no indication that it is spoilt.
We learned have been a keen cook for over 60 years. Since most subway sandwiches have preservative as their major flavor you probably do not need to refrigerate them at all. A couple of days max.
This of course begs the inquiry “How long do deli sandwiches last in the fridge?”
Deli meat ought to last at least a week in the fridge, but that’s in no way guaranteed. If you ever see any mold on your sandwich or the meat smells bad, toss it. Don’t risk it. Food poisoning can ruin not just your day, but your entire week.
Then, is it safe to eat a Subway sandwich that has expired?
So far as food safety, a lot depends on how fresh the ingredients were when you left Subway, and you have no way of knowing that, especially with the meat. Deli meat ought to last at least a week in the fridge, but that’s in no way guaranteed. If you ever see any mold on your sandwich or the meat smells bad, toss it. Don’t risk it.
How long can you keep a subway sub for?
In general, I wouldn’t recommend keeping a sub for more than two days, but as I said, it depends on the type. If you need to keep one in the fridge for three days, one using sausage or deli meat should be okay. I’d also keep veggies to a minimum (especially the “wetter” ones), and minimal sauce.
Do sub sandwiches get better with age?
The idea behind a freshly made sub sandwich is that you intend to eat it right away. They do not improve with age. The bread cannot stand up to refrigeration, not even for an hour. If you wrap it up really well and put in the fridge, the crust on the outside of the sub roll will go soft. Cold air makes bread dry and tough.
One inquiry we ran across in our research was “Do toasted sandwiches need to be refrigerated?”.
I especially do not recommend refrigerating a toasted sandwich because the bread only stays “toasty” for so long. If you do have to refrigerate it, I recommend not toasting it, minimal veggies (especially ones with high water content), and minimal sauce.
