If you are talking about unopened packaged granola, it has a shelf life of about 6 months. However, once you open the package, you can expect opened granola to stay fresh for about 3 to 4 months.

When it comes to homemade granola, the shelf life is shorter. Homemade granola typically has a shelf life of about one month, considerably faster than packaged granola. 

Homemade granola bars have a shelf life of about 7-10 days, shorter than homemade granola. 

Regarding storing granola, both the pantry and the fridge are good options. However, it’s essential to ensure the granola doesn’t come into contact with direct sunlight, which can cause it to spoil more quickly.

Packaged granola bars can last a decent amount of time, about 3-4 months. If you’re storing your granola bars at room temperature, keeping them in a cool, dry place away from direct sunlight or moisture is essential. This can help extend their shelf life and prevent them from becoming stale or moldy.

If you’ve opened a package of granola bars, they may not last as long as unopened ones. In general, it’s best to consume them within a week or two of opening to ensure optimal freshness and flavor.

How Long Does Homemade Granola Last?

If you want to make granola at home, you may wonder how long it will last before going bad. The homemade granola lasts for 7 to 10 days. This is because homemade granola bars do not contain any preservatives. 

So, it’s likely to get spoiled easily. Therefore, storing it in an airtight container and keeping it in the fridge is best. So, you are assured of at least a week of its safety and can enjoy them fresh in the morning.

How To Tell If Granola Is Bad?

Granola will show you some signs of spoilage when it has gone wrong. If you’re unsure about your granola, no worries; we’ve got you covered. Here are a few easy ways to check if your granola has passed its prime:

1. Smell It 

Fresh granola will smell nutty, oaty, and delicious. If your granola smells stale, moldy, or just “off,” chances are it’s time to discard it.

2. Check If Its Stale

Stale granola will lose its crunch and become soft. Give it a taste – if it’s chewy or soggy instead of crunchy, it’s stale. Stale granola won’t hurt you, but it won’t taste great.

3. Check The Texture

Granola should be crunchy with intact oats, nuts, and dried fruit pieces. If everything is mushy or crumbling into crumbs, that’s a sign your granola has gone wrong.

4. Look For Mold

This one’s obvious, if you see spots of mold growing on your granola, don’t eat it! It’s best to discard the entire container.

5. Inspect Any Insects

Finally, inspect for any insects or larvae. Little bugs like moths, beetles, or their larvae love granola. Check for any webbing, crawling critters, or worm-like larvae in the granola. If you spot these, throw out your granola immediately.

How To Store Granola To Extend Its Shelf Life?

So you have made a fresh batch of delicious granola and want to retain its flavors and crunchiness for as long as possible? Proper storage is critical. It can go stale quickly if you don’t store your granola correctly. 

But follow these tips below, and you will notice a big difference in how your granola looks and tastes, even after a few weeks.  

1. Keep The Air Out 

Transfer your granola to an airtight container or sealable plastic bag after it cools. Oxygen exposure is the enemy of freshness. Seal up that bag or click on the lid after each use.

2. Find A Cool, Dry Place To Store It 

Heat and humidity are not granola-friendly. Your pantry, cupboard, or cabinet away from the oven or stovetop is perfect. 

3. Refrigeration

If refrigeration is a must due to weather or kitchen conditions, use a container with an airtight seal and consume refrigerated granola within 2 to 3 weeks. Let it come to room temperature before eating for maximum crispness.

Remember to check on your granola every week to ensure no moisture build-up. A well-sealed container should prevent air exposure, but it’s best to check, as temperature and humidity changes can sometimes cause unseen condensation.

Can You Freeze Granola?

Granola is one of those foods that could freeze better. I know it’s disappointing, especially if you made a big batch of homemade granola to enjoy for weeks. When you freeze granola, it loses its signature crunch. 

As granola sits in the freezer, moisture builds up on the ingredients and causes them to soften. Once thawed, the granola will be soggy and mushy. 

All those chunky nuts, crispy oats, and sweet clusters won’t have the same satisfying chew. The flavors can also dull in the freezing process. However, if you are looking to freeze granola, here are some tips to keep in mind:

  • If you have leftover granola you want to freeze, do so immediately after making it. Flash-freezing granola at its freshest will help retain the most crispness.
  • To ensure a crunchy texture, thaw frozen granola in the refrigerator overnight. Once melted, spread on the baking sheet and bake at 300 degrees Fahrenheit in the oven for 10-15 minutes.
  • Consider freezing granola in portions so you’re only thawing what you need.
  • Add freeze-dried fruit, nut butter, or dried yogurt chips to your granola before freezing to compensate for lost crunch upon thawing.

The Risk Of Consuming Expired Granola

So, you’re thinking about eating that granola sitting in your pantry for a while, but you’re still determining if it’s safe to consume. Let’s talk about the risk of consuming expired granola.

The main risk of consuming expired granola is the potential for the oils in the nuts and seeds to go rancid. Rancid oils can produce harmful compounds that cause digestive issues, such as nausea and diarrhea. 

Expired granola that has been exposed to moisture or humidity may also develop mold, which can be harmful if consumed.

We learned that unopened granola lasts about six months, while opened granola stays fresh for 3 to 4 months. Homemade granola, on the other hand, has a shorter shelf life of around one month. And if you’re wondering about packaged granola bars, they typically have a 3 to 6 months shelf life.

But wait, there’s more! We also discussed some telltale signs of spoilage to keep an eye out for, such as a strange smell, unusual texture, mold growth, or the presence of insects. And, of course, if your granola tastes stale, it’s time to toss it out.
