How long can a sandwich last in the fridge?

In this article, we will answer the question “How long can a sandwich last in the fridge?”, how to tell if the sandwich has gone bad, does an assembled sandwich have a shorter shelf life, and how to make your sandwiches last longer.

How long can a sandwich last in the fridge?

Depending on what you put in the sandwich, it will last 3-4 days in the ridge if it was refrigerated properly within 2 hours of its assembling. Sandwiches with highly perishable ingredients like meat and fish will naturally have a shorter shelf-life. 

Note that this mentioned shelf-life is for best quality only. As long as the sandwich is properly handled and stored, it won’t go bad after 3-4 days but it may not be as fresh. 

The bottom line is that sandwich will last only as long as the estimated shelf-life of its most perishable ingredient. 

How to tell if the sandwich has gone bad?

Sandwiches are a cold food item so you must inspect them closely to check for any potential signs of spoilage. Following are the telltale signs of your sandwich going bad.

Smell: A bad sandwich will smell bad. The smell might be coming from the bread itself or one of the fillings. In either case, the sandwich is no longer fit for consumption. 

Texture: If the sandwich is soggy or stale, it may be safe to eat. But who likes soggy sandwiches. You can discard it for quality purposes. However, a slimy or mushy sandwich is spoiled.

Mold: Mold appears in the form of green, white, or black fuzzy spots or patches on the bread surface or in any of the fillings. A moldy sandwich causes food poisoning and should be immediately gotten rid of.

Taste: This should be the last step of your inspection. If all else feels alright, go ahead and taste-check just a bit of the sandwich to give the final verdict. If the taste is off, discard the sandwich. 

Does an assembled sandwich have a shorter shelf-life?

Yes, an assembled sandwich has a shorter shelf-life than the shelf-life of one of its most perishable ingredients. But the difference in the shelf-life is not significant. 

For example, when the cheese slice is removed from its covering and placed over the damp spread, it ought to go bad rather quickly. The same goes for bread, pickle, and other ingredients such as meat.

How to make your sandwich last longer?

Choose the right type of bread 

Go for crusty bread like baguettes if your sandwich contains solid ingredients like meat and cheese. It also prevents sogginess. Whereas soft white bread is more suitable for spreads like mayo. 

Toast the white bread to lower its moisture level. This will contribute to a longer shelf-life. In any case, make sure the bread is the freshest.

Prefer using dry fillings over wet ones

Wet ingredients or the ones with a greater moisture content such as tomatoes, and lettuce could be sandwiched between the dry ingredients. 

Lightly butter the inside of the bread to prevent it from absorbing moisture from the fillings. Make sure the veggies are properly washed and dried before assembling the sandwich.

Keep a barrier between the condiments and bread 

Do not apply the condiments directly to the bread or else you will end up with mushy bread within a day. Spread the condiment over a layer of cheese or meat to prevent it from seeping into the bread.

Save the assembling for last minute 

Keep the ingredients ready and separately stored in the fridge. When you are ready to eat your sandwich, you just need time for assembling it. 

Properly wrap the sandwich 

For wrapping, you can use a ziplock bag, tin foil, parchment paper, or waxed paper. We do not recommend using a ziplock bag as it accumulates the moisture within it. 

Use tin foil if you want to keep your sandwich warm for longer or intend to warm it later on. Otherwise, go for wax paper or parchment paper because it is both, economical and appropriate.

Pack the sandwich 

To do the packing, use a Tupperware container. It not only provides added protection against spoilage but also sports the flimsy structure of your bread or sandwich.

If the sandwich is just wax paper or foil-wrapped, avoid putting anything heavy over it as it can squish your sandwich.

Keep your sandwich refrigerated 

Refrigerate your sandwich at 40F or below. Take it out just before eating. If you are taking your sandwich along with you on travel, use frozen gel packs to keep the sandwiches cool. 

If it is a road trip with many hours of driving, install an insulated cooler in your car to keep your sandwiches and other perishable food items fresh.
