How do you keep unused biscuits fresh?

Keeping unused biscuits fresh for as long as possible can seem like a challenge. Biscuits tend to go stale quickly once they are opened, especially in humid environments. However, with the right storage methods, you can extend the shelf life of biscuits by days or even weeks. Here are some helpful tips for keeping unused biscuits tasting great.

Why Do Biscuits Go Stale?

Before getting into the storage methods, it’s important to understand why biscuits go stale in the first place. There are two main reasons:

  • Moisture loss – As biscuits sit exposed to air, they lose moisture. This causes them to dry out and become crunchy or hard.
  • Fat absorption – When biscuits are exposed to air, the fats in them can absorb aromas and flavors, causing a sensory change.

By minimizing air exposure, you can slow down these staling processes and extend the freshness. Proper storage methods help achieve this goal.

Use an Airtight Container

The best way to keep unused opened biscuits fresh is to store them in an airtight container. This prevents outside air from circulating around the biscuits, leading to moisture loss and fat absorption. Suitable airtight containers include:

  • Plastic containers or bags with an airtight seal
  • Metal tins or canisters with a tight-fitting lid
  • Glass jars with an airtight lid

When placing the biscuits in the container, press out any excess air before sealing to minimize internal air space. Just make sure not to crush the biscuits! Store the sealed container of biscuits in a cool, dry place like the pantry or cupboard.

Recommended Airtight Containers

Container Description
Plastic container Look for rigid plastic containers with an airtight snap-on lid. Square or rectangular shapes work best.
Metal tin Opt for an opaque, food-grade tin with a tight sealing lid to keep out air and light.
Glass jar Use a wide-mouth jar with a tight screw-on or clamp lid to seal in freshness.

Use Plastic Freezer Bags

For short term storage, you can also place unused biscuits in plastic freezer bags. Ensure you press out excess air before sealing the bag tightly. Then store the bag of biscuits in the freezer, which will hugely slow down staling. The low temperatures will help the biscuits retain moisture and freshness for longer.

Freezer bags made specifically for the freezer will protect against moisture condensation. Lay the filled bag flat in the freezer so the biscuits keep their shape.

Wrap in Aluminum Foil

Wrapping unused biscuits tightly in aluminum foil is another effective storage method. Make sure to wrap the foil tightly around the biscuits with minimal air trapped inside. Then store the foil-wrapped biscuits in an airtight container or plastic freezer bag for extra protection.

The aluminum foil creates a protective barrier against air, light, and aromas. This prevents moisture loss and keeps the biscuits fresher for longer compared to unwrapped biscuits. Just remember to seal or replace the foil with fresh foil each time you open the biscuits.

Use Wax Paper

Wax paper can also be used to wrap unused biscuits before storage. The wax coating helps retain moisture and creates a barrier against fat absorption. Simply wrap the biscuits tightly in a layer or two of wax paper before placing in an airtight container or freezer bag.

As an alternative, place a sheet of wax paper in your storage container before adding the biscuits. The wax paper will help shield the biscuits from air exposure on one side, extending freshness.

Store at Cool Temperatures

In addition to the right storage containers and materials, storing biscuits at cool temperatures helps optimize freshness. The ideal temperature range is 55-65°F. Some storage tips to keep biscuits cool:

  • Pantry or cupboard – Choose a cooler spot away from appliances or warm windows.
  • Fridge – Keep in an airtight container for up to 1 week.
  • Freezer – Store in freezer bag or foil for 1-2 months.

Avoid hot spots like near ovens or under direct sunlight, as heat will speed up staling.

Watch Out for Condensation

When storing biscuits in the fridge or freezer, moisture condensation on the surface is another factor that can lead to premature staling. Opening cold biscuits leads to condensation forming from the humidity. Here are some tips to minimize condensation:

  • Allow refrigerated biscuits to come to room temperature before opening.
  • Let frozen biscuits thaw for 15-20 minutes before opening.
  • Transfer to an airtight container at room temperature as soon as possible.

Wiping off any noticeable condensation right away also helps reduce moisture absorption.

Use an Oxygen Absorber

For very long term storage, consider using an oxygen absorber packet. These packets soak up the oxygen inside your airtight biscuit container. With less oxygen, oxidation reactions are slowed down which keeps biscuits fresher for longer.

Oxygen absorber packets are available to purchase online or at some grocery and hardware stores. Follow the package instructions carefully. Typically, you activate the packet and place it in the storage container before adding the biscuits.

With an oxygen absorber, you can keep unused biscuits fresh for up to 6 months. Just monitor the biscuits occasionally and replace the oxygen absorber as needed.

Consider Vacuum Sealing

If you want maximum freshness for unused opened biscuits, consider vacuum sealing them. Vacuum sealing removes nearly all the air from the packaging before sealing shut. This dramatically slows down staling and oxidation.

To vacuum seal biscuits:

  1. Place the biscuits in a vacuum sealing bag.
  2. Attach the open end of the bag to your vacuum sealing appliance.
  3. Activate the vacuum process to remove the air.
  4. Once vacuum is achieved, use the appliance to seal the bag shut.

Vacuum sealed biscuits stored in the freezer can stay remarkably fresh for 6 months or longer. Just be sure to thaw and let come to room temperature before opening to prevent condensation.

Maintain Proper Hygiene

No matter which storage method you use, maintaining proper hygiene when handling biscuits is also key. Always use clean utensils and containers to package the biscuits. Wash your hands thoroughly before touching biscuits if repacking them. Avoid sneezing or coughing directly on the biscuits when open.

Keep biscuit containers and kitchen surfaces clean. Never place biscuits on an unsanitary surface when transferring them to a container. Follow the basic rules of food safety.

Use Biscuits in a Timely Manner

Keep in mind that even with the best storage, biscuits will eventually go bad. Throw out any biscuits that smell, taste or look off. Use your properly stored biscuits within these timelines for optimal freshness:

  • Pantry: 1-3 weeks
  • Fridge: 1-2 months
  • Freezer: 3-6 months

Date your biscuit containers so you know when they were originally opened or stored. First in, first out is a good system to use oldest ones first.

Revive Stale Biscuits

If despite your best efforts, stored biscuits end up a little stale, don’t toss them out yet! There are some tricks to temporarily revive stale biscuits:

  • Heat in oven – Bake biscuits on low heat 200°F for 5 minutes to restore crispiness.
  • Microwave – Zap biscuits for 10-20 seconds to soften then crisp under broiler.
  • Apple slice – Place apple slices in airtight container overnight to add moisture.
  • Bread dough – Add a small piece of fresh dough to container to release humidity.

Try combining these techniques to freshen up less-than-fresh biscuits before serving.


Following proper storage methods can keep unused opened biscuits fresh and delicious for much longer. The keys are minimizing air exposure, keeping cool, and monitoring freshness. With the right containers and materials, biscuits can stay enjoyable for weeks past opening.

Airtight containers, plastic bags, foil, and wax paper all prevent air circulation and moisture loss. Refrigerator and freezer temperatures slow down staling. Oxygen absorbers remove air while vacuum sealing takes it a step further. Maintaining cleanliness and using biscuits in a timely manner also helps.

While biscuits will eventually go stale, you can take steps to prolong their shelf life. With the tips above, you’ll always have fresh, tasty biscuits ready to enjoy!
