How to Tell If Tortillas Are Bad
Tortillas are bad when you see fuzzy mold or dark spots, smell something sour or musty, or feel a slimy surface. Store-bought tortillas last about 1 to 2 weeks in the pantry and 3 to 4 weeks in the fridge once opened.
Signs Tortillas have gone bad
- Mold spots. Fuzzy green, white, or black patches, often starting along the folds or edges. Toss the whole package, since spores spread easily in a sealed bag.
- Sour or off smell. Fresh tortillas smell mild and toasty. A tangy, yeasty, or musty odor means they've turned.
- Slimy or wet surface. Condensation trapped in the bag can create a sticky film. If tortillas feel slick rather than just soft, discard them.
- Pink or gray discoloration. Patches of unusual color on flour tortillas point to bacterial or mold growth, not normal aging.
Looks weird, but it's fine
- Brittle or cracking edges. Dried-out tortillas are just stale. Warm them in a damp towel or pan to soften, or fry them into chips.
- Small brown or toasted spots. Dark flecks from the griddle during cooking are normal, especially on flour and corn tortillas.
- Slightly stiff after refrigerating. Cold makes tortillas firm. They loosen up after a few seconds on a hot pan.
How long do Tortillas last?
| Where | How long | Note |
|---|---|---|
| Pantry (unopened) | Until the date on the package, often 1 to 2 weeks past | Check for mold before using |
| Pantry (opened) | About 1 week | Reseal tightly |
| Fridge (opened) | 3 to 4 weeks | |
| Freezer | 6 to 8 months | Separate with parchment first |
How to store them
- Press out the air and seal the bag or use a zip-top bag after each use.
- Freeze extras flat with parchment between stacks so you can peel off just what you need.
- Refrigerate opened packs if your kitchen is warm or humid.
Use it up before it turns
Frequently asked questions
How long are tortillas good after opening?
About a week at room temperature and 3 to 4 weeks in the fridge, if sealed well. Fresh refrigerated tortillas from a tortilleria may have a shorter window, so follow the package date.
Can you eat tortillas with a little mold on them?
No. Soft foods like tortillas let mold roots spread beyond what you can see. Discard the whole package if you spot any.
Why are my tortillas hard?
They've dried out, which is a quality issue and not a safety one. Warm them briefly on a skillet or in a damp paper towel in the microwave to bring them back.
