Expiration & Storage Tips
When does hamburger bun expire?
Hamburger buns usually stay fresh for about 5-7 days after you buy them from the store, if unopened. If you've opened the package, try to use them within 2-3 days. The 'best by' or 'sell by' date is typically a good indicator of their freshness, but they can still be safe to eat a few days after this date, as long as they've been stored properly and show no signs of spoilage. If you've made homemade hamburger buns, they'll typically last for about 2 days at room temperature, or up to a week if you keep them in the fridge. Freezing hamburger buns is a great way to extend their lifetime, as they can last for about 1-3 months in the freezer.
How do you tell if hamburger bun is bad?
An old or spoiled hamburger bun may smell sour or yeasty, which is a sign that it's started to turn. If you see blue or green mold on the surface of the bun, or if the bun has become hard or stale, then it's likely time to toss it. It's important to remember that mold can be better seen on light-colored buns, dark or whole grain buns may also get mold but it may be harder to spot, so when in doubt, throw it out.
Tips for storing hamburger bun to extend shelf life
• Keep them stored in a cool, dry place- your pantry or bread box are perfect
• Don't let the buns sit in the grocery bag - put them in a plastic bag that you can seal
• Squeeze out excess air from the bag before sealing to protect from humidity and bugs
• If you plan on storing them for longer than a week, freeze them. You can defrost what you need by leaving out at room temperature for a few hours before you plan to use them.
• Don't refrigerate the buns as this will actually make them stale faster due to the redistribution of moisture throughout the bun
