Yes, granola can go bad over time, especially if it's not stored properly. Granola bars, like other foods, can become stale or lose flavor after their expiration date.
To keep Granola and granola bars fresh, store them in a cool, dry place and check for changes in taste or smell.

Store bought granola and homemade granola have a different shelf life. I've created a chart below to show how long each type of granola will last in according to different storage conditions.

Tips To Tell If Granola Has Gone Bad
Here's a guide to help you identify signs of spoilage in both granola bars and loose granola.
- Check the Granola Bag: Inspect the packaging for any signs of damage or exposure to air, which can speed up spoilage.
- Off Smell: Open the granola bag and take a sniff. A sour or off smell indicates the granola has likely expired.
- Texture Changes: Feel the granola bar. If it's overly hard or too soft, it may be stale granola that's no longer fresh.
- Appearance: Look for any discoloration or mold on the bar, which are clear indicators of spoilage.
Ways To Store Granola Properly
Storing granola bars correctly ensures that they remain fresh and delicious, whether they're homemade or store-bought. Each storage method has its own guidelines, so here's a detailed guide on how to keep your granola bars at their best.

- Remove from Freezer: Take granola bars out of the granola bag and place them on a plate.
- Room Temperature Thawing: Leave the bars at room temperature for 1-2 hours.

Is It Okay To Eat Expired Granola?
Eating expired granola is not recommended, but it's not always harmful. Sometimes, you may be able to tell if the food has gone bad by its smell, texture, or months past its expiration date. However, it's always best to err on caution and throw it out if you're unsure.
Store-Bought Granola
- Beyond Expiration Date: Granola from the store is generally safe to eat a few months past its expiration date due to its plant-based ingredients.
