Flour tortillas are a staple in many kitchens, especially if you’re a fan of Tex-Mex cuisine, burritos, fajitas, or wraps of any kind. They’re soft, flexible, and perfect for wrapping around any filling, from grilled chicken to sautéed veggies or even just a simple smear of butter. But have you ever wondered, “Can flour tortillas go bad”?
It’s not a question you may think about until that moment you’re staring at the last few tortillas in the pack, unsure whether they’re still good to eat or if they’ve outlived their prime. Well, like any food item, flour tortillas do have a shelf life, and they can spoil. The key is knowing how long they last, how to spot signs of spoilage, and what you can do to extend their life. In this post, we’ll dive into everything you need to know to ensure your tortillas stay fresh, tasty, and safe to eat.
Can Flour Tortillas Go Bad?
Yes, flour tortillas can absolutely go bad, and they do have an expiration date. But the good news is, they don’t usually spoil quickly like some other foods. However, just like any packaged food, they can degrade in quality over time and may eventually become unsafe to eat. The main factors that determine how long they last include how they’re stored, whether they’re opened or not, and if any preservatives are used in the packaging.
Flour tortillas are made with a combination of flour, water, fat (like oil or lard), salt, and baking powder. While these ingredients are relatively stable, the tortillas are still perishable. If you don’t store them properly or if they’ve been exposed to air and moisture for too long, they can spoil.
Shelf Life For Flour Tortillas

The shelf life of flour tortillas depends on a variety of factors, including the brand, packaging, and whether they’ve been opened or not. Typically, flour tortillas come with a ’best by’ or ’expiration’ date on the package. But keep in mind, these dates are often more of a guideline rather than an absolute deadline. Here’s a breakdown of how long they last:
-
Unopened Packaged Flour Tortillas
- If stored properly (in a cool, dry place, away from direct sunlight), unopened flour tortillas can last anywhere from 1 to 3 months past the ’best by’ date. That being said, they might still be safe to eat for a little longer, but their flavor and texture may deteriorate.
-
Opened Packaged Flour Tortillas
- Once you’ve opened the package, the tortillas will start to lose their freshness a lot quicker. Generally, they last about 7 to 10 days at room temperature, or you can extend their shelf life by refrigerating them, which could keep them fresh for 2 to 3 weeks.
-
Homemade Flour Tortillas
- These tend to have a shorter shelf life because they contain no preservatives. If kept at room temperature, homemade flour tortillas may last for 2 to 3 days before they begin to lose their quality. Refrigerating them can extend their life to about a week.
Common Signs Of Spoilage
Even though flour tortillas tend to last longer than other perishable items, they can still go bad. The tricky part is that they don’t always show obvious signs of spoilage, so you’ll need to be vigilant. Here are the most common signs that your tortillas have gone bad:
-
Smell
- Fresh tortillas have a neutral, slightly floury smell. If they develop an off or sour smell, it’s a clear sign they’ve gone bad. The smell can range from musty to distinctly rancid, which usually happens when the oil or fat in the tortillas goes stale.
-
Texture
- Fresh tortillas are soft and pliable. If they become stiff, dry, or brittle, they’re likely past their prime. Tortillas that feel like cardboard are no longer enjoyable to eat.
-
Mold Or Discoloration
- This is one of the most obvious signs that your tortillas are no longer safe to eat. If you see any mold growth on the surface, or if the tortillas have spots of green, blue, or black discoloration, throw them away immediately.
-
Wrinkling Or Cracking
- If your tortillas are starting to show signs of wrinkling or cracking (and you’re certain it’s not from a slight bend in the package), they’re likely drying out. This doesn’t necessarily mean they’re spoiled, but their texture will suffer, and they’ll be less enjoyable.
-
Off Taste
- If they taste strange, sour, or stale when you bite into them, it’s a sign they’re no longer fresh. This could also mean the oils used in making them have gone rancid.
How To Store Flour Tortillas?

The key to preserving the freshness of your flour tortillas lies in proper storage. Here’s how to store them depending on your situation:
-
Room Temperature (Short-term storage):
- If you’re planning to consume the tortillas within a week, you can keep them at room temperature. Store them in a cool, dry place, away from direct sunlight, and preferably in their original packaging.
- Tip: Once the package is opened, you might want to put the tortillas in a resealable plastic bag to protect them from air exposure and moisture.
-
Refrigeration (Medium-term storage):
- For longer freshness, place the tortillas in the fridge. This is particularly important for opened packages or homemade tortillas.
- Tip: To prevent them from sticking together, you can layer the tortillas with a piece of parchment paper or wax paper between each one. Also, try to seal the bag or container tightly to keep them from absorbing unwanted moisture or odors from other foods.
-
Freezing (Long-term storage):
- Freezing is your best bet if you have a large batch of tortillas and don’t think you’ll be able to eat them all within a couple of weeks. Flour tortillas freeze really well and can last up to 6 months or longer.
- Tip: Place wax paper or parchment paper between each tortilla to prevent them from sticking together. Then, put the stack in an airtight freezer bag or container. When you want to use them, just pull them out and heat them up directly from frozen or let them thaw in the fridge.
Expert Tips
To maximize the freshness of your flour tortillas and avoid them going bad prematurely, here are some expert tips:
- Avoid storing tortillas in damp or humid environments, as moisture is a major culprit in promoting mold growth.
- Don’t leave tortillas out for extended periods, especially in a warm kitchen. Room temperature is fine for a few hours but should not exceed a day or two.
- Preheat your tortillas before use, especially if they’ve been stored in the fridge or freezer. A quick 10-15 second heat in a skillet or microwave helps restore their softness and flavor.
- Vacuum-sealing tortillas for long-term storage (especially when freezing) can further prevent air and moisture from affecting their quality.
- Use a tortilla warmer if you’ve got one-it’s perfect for keeping them warm and fresh for an extended period without drying them out.
