Leftovers — you either love them or hate them. With prices of just about everything skyrocketing, I am a firm believer in leftovers now more than ever. I can certainly appreciate the opportunity to nourish my body at my own convenience and with little to no effort — but limiting food waste in the process is the icing on the cake. In the US, an estimated 30% to 40% of the total food supply is wasted across production, retail and consumer chains, according to the Department of Agriculture. The trick to leftovers is storing them properly to extend their shelf life. 

So what’s my secret? I crafted this guide of everything you need to know to properly store your leftovers or fresh groceries, limit food waste and ultimately save you money. Keep your favorite produce, dairy, meat and other products fresher for longer by following these storage tips. For more, read about the best way to reheat every kind of food and how to clean out your fridge.

Basic food storage tips

For starters, there are some basic rules for storing any kind of food to prevent contamination, bacteria or spoiling. It’s important to remember that even if foods look fine and don’t have any visible mold, they could be unsafe to eat, potentially causing foodborne illnesses or sickness. Here are some quick storage tips to get started:

  • Make sure all perishable items and leftovers are stored in the fridge or freezer to prevent bacteria. 
  • Don’t leave leftovers outside of the fridge for more than 2 hours after the food was made.
  • Toss your leftovers after four days (or sooner depending on how they look).
  • Keep your fridge below 40 degrees Fahrenheit and your freezer below 0 degrees for longest lasting results. According to the USDA, bacteria thrives in temperatures between 40 and 140 degrees Fahrenheit.
  • Wrap your food airtight to preserve moisture, prevent odor and keep out bacteria.
  • Store your leftovers in small portions in shallow containers or reuseable bags or with food wrap. 

How to store every kind of food

Here’s how to organize each kind of food so you can enjoy your groceries for longer. 

Dairy

Few things churn my stomach like the smell and taste of spoiled dairy. Milk, yogurt and other dairy products typically expire within a few short days, but we found tips to extend their longevity.

  • Keep dairy products cold, ideally between 32 and 38 degrees Fahrenheit. Dairy products expire 50% faster for every 5 degree increase over 38 degrees Fahrenheit.
  • Don’t keep dairy products out of the fridge for more than a few minutes.
  • Don’t store dairy products, especially milk, in the fridge door, since that’s the warmest part of the fridge. 
  • Leave dairy products in the original store packaging they came in. 
  • Keep hard cheeses in the store wrapping. Wrap leftovers in airtight foil or plastic wrap. (Find out more about proper cheese storage here.)
  • Don’t allow ice cream to soften and re-freeze too many times, and always keep it in the main part of the freezer rather than the door.

Meat, seafood and poultry

It’s important to store meat products correctly considering the risk of foodborne illnesses like salmonella and E. coli. The USDA recommends that all meat products be eaten within four days of being in the fridge — though meat can be frozen for several months safely. When storing, you should follow these tips:

  • Store meat products in their own drawer to prevent cross-contamination. 
  • Keep meat products in the lowest drawer in the fridge to prevent any drippings on other groceries. 
  • Store the meat in the coldest part of the fridge. Ideally, set the drawer to 29 degrees Fahrenheit. 
  • Keep the meat in the original store wrapping and secure it in a plastic bag or leakproof container to avoid spillage. 
  • Don’t refreeze raw meat that has already been defrosted.

Fresh produce 

Fruits and vegetables are often stored incorrectly. Here’s a quick guide for reference:

  • Store fruits and vegetables separately or spaced away from each other. This is because you want to minimize build-up of ethylene gas, a compound released by some fruits and vegetables that causes produce to ripen faster.
  • Fruits and vegetables stored outside of the fridge — like tomatoes, potatoes, onions and avocados — should be removed from the store wrapping and left in cool, dry and dark areas in your kitchen. 
  • Leave all other fruits and vegetables in their original store packaging, or cut in stored in airtight containers.
  • Avoid washing your fresh produce before putting in the fridge. The moisture can speed up the process for rot and mold. 
  • Keep citrus, tomatoes and avocados at room temperature, but refrigerate them once they’re past prime ripeness. 
  • Store all fruits and vegetables out of direct sunlight.
