Corn lasts 1 to 3 days in the fridge when whole ears are stored in the husk, 1 to 2 days once husked, and 3 to 5 days after cooking — whether it was boiled or grilled. Creamed corn and corn salads or salsas keep for 3 to 4 days in an airtight container, and blanched frozen corn holds its best quality for 8 to 12 months in the freezer. The durations below are the conservative figures to follow for safety and best flavor.
Corn on the cob keeps about 1 to 3 days in the refrigerator (husked corn dries out and is best within 1 to 2 days), while cooked corn in an airtight container lasts 3 to 4 days; frozen, blanched corn holds its quality for 8 to 12 months. For steady cold that keeps corn fresh, compare current refrigerators.

How Long Does Fresh Corn Last in the Refrigerator?
Whole Corn on the Cob
Whole corn on the cob keeps for 1 to 3 days in the fridge at peak sweetness. Leave the husks on — they act as a natural barrier that retains moisture and keeps the kernels from drying out. Place the ears in a perforated plastic bag or wrap them loosely in a damp paper towel before refrigerating. Corn's sugars begin converting to starch the moment it is picked, so the sooner you eat it, the sweeter it tastes.
| Storage Method | Shelf Life |
|---|---|
| Whole corn on the cob (with husk) | 1-3 days |
| Husked corn on the cob | 1-2 days |
Husked Corn
Husked corn dries out faster and should be eaten within 1 to 2 days. Wrap the ears tightly in plastic wrap or seal them in an airtight container to slow moisture loss. Do not wash corn before storing — surface moisture accelerates spoilage. Wash it only when you are ready to cook.
Fresh-Cut Corn Kernels
Kernels cut fresh from the cob keep for 1 to 3 days in the fridge. Store them in a plastic or glass container with a tight-fitting lid to keep them from drying out and from absorbing odors from other foods in the fridge.
Does Corn Go in the Fridge?
Yes — fresh corn should be refrigerated as soon as possible after purchase. Cold temperatures slow the sugar-to-starch conversion and the spoilage process, so corn left on the counter loses sweetness and firmness much faster than corn stored at fridge temperature. Set your refrigerator to 40°F or below for the longest hold times.
How Long Does Cooked Corn Last in the Fridge?
Cooked corn — boiled, grilled, or steamed — lasts 3 to 5 days in the refrigerator. Let it cool to room temperature, then move it to an airtight container or wrap it tightly in aluminum foil or plastic wrap. This retains moisture, keeps the corn from drying out, and stops it from absorbing other fridge odors.
Grilled or Boiled Corn on the Cob
| Storage Method | Duration in Fridge |
|---|---|
| Airtight container | 3-5 days |
| Aluminum foil/plastic wrap | 3-5 days |
Store the wrapped corn in the coolest part of your fridge. When ready to eat, reheat by steaming, microwaving, or grilling it briefly. If you notice any change in texture or smell before day 5, discard it.
Corn Salad or Salsa
Corn salad or salsa keeps for 3 to 4 days in a tightly sealed airtight container. Stir before serving to redistribute any separated ingredients. If you're curious about similar items, see how long does salsa verde last in the fridge?.
| Storage Method | Duration in Fridge |
|---|---|
| Airtight container | 3-4 days |
Creamed Corn
Creamed corn lasts 3 to 4 days in the fridge. Let it cool completely to room temperature, then transfer it to an airtight container to keep the creamy texture from drying out. If you notice the cream separating or a sour smell, throw it out.
| Storage Method | Duration in Fridge |
|---|---|
| Airtight container | 3-4 days |
Freezing Corn: How Long Is Frozen Corn Good For?
Blanched frozen corn holds its best quality for 8 to 12 months in the freezer. Frozen corn kept constantly frozen stays safe beyond that window, but flavor and texture decline — and air left in the packaging causes freezer burn.
Whole Corn Kernels
- Blanching: Boil corn on the cob for 4-6 minutes depending on ear size (3-4 minutes for cut kernels), then immediately transfer to ice water to stop the cooking. Blanching preserves color, flavor, and texture.
- Cutting kernels: Once the corn is cool and patted dry, cut the kernels off the cob with a sharp knife.
- Packaging: Place the kernels in airtight freezer bags or containers, pressing out as much air as possible to prevent freezer burn.
- Labeling: Label each bag with the date so you can track freshness and use the oldest first.
| Step | Description |
|---|---|
| Blanching | Boil cobs 4-6 minutes (kernels 3-4 minutes), then cool in ice water |
| Cutting kernels | Remove kernels from the cob |
| Packaging | Store in airtight freezer bags or containers, air removed |
| Labeling | Add date for tracking freshness |
Corn on the Cob
Whole ears freeze well too: blanch 4-6 minutes, cool in an ice water bath, pat completely dry, and seal in freezer-safe bags. Blanched corn on the cob keeps 8-12 months at best quality. Thaw in the fridge or use directly in recipes.
| Storage Method | Shelf Life in Freezer |
|---|---|
| Whole corn on the cob (blanched) | 8-12 months |
| Fresh corn kernels (blanched) | 8-12 months |
Creamed Corn
- Preparation: Cook the corn and prepare your creamed corn recipe as usual.
- Cooling: Allow the creamed corn to cool completely.
- Packaging: Transfer it into airtight containers or freezer bags.
- Labeling: Label with the date to monitor freshness.
Frozen creamed corn keeps 8-12 months at best quality, so you have a side dish ready whenever you need it. For more freezer guidance, see how long does gragnano pasta last in the fridge and how long does quiche last in the fridge.
Signs of Spoilage: Does Corn Go Bad in the Fridge?
How to Identify Spoiled Corn
Yes, corn goes bad in the refrigerator — usually within days rather than weeks. Check for these signs before eating:
- Mold: Black, green, white, or blue fuzzy patches on the kernels, cob, or husk mean the corn must be discarded.
- Discoloration: Fresh kernels are bright yellow or white and plump. Kernels that turn dull, brown, reddish, or develop dark spots are spoiling. If your corn is turning red or pink in the fridge, treat it as discoloration and discard it — color change signals the corn is past its prime.
- Texture: Fresh corn feels firm and plump. Mushy, shriveled, or dried-out kernels, or a slimy or sticky surface on the cob, indicate bacterial growth.
- Smell: Fresh corn smells mildly sweet and earthy. A sour, rotten, or otherwise unpleasant odor is a clear sign it has gone bad.
| Spoilage Cue | What It Looks Like |
|---|---|
| Mold | White, blue, green, or black fuzzy patches |
| Discoloration | Dull, brown, or reddish kernels; dark spots |
| Texture change | Mushy or shriveled kernels; slimy or sticky cob |
| Off smell | Sour or rotten odor instead of sweet and earthy |
When to Discard Corn
- Mold presence: Any mold means discard immediately.
- Off smell: A sour or foul odor means the corn should be thrown away.
- Texture changes: Mushy kernels or a slimy cob mean it's time to toss it.
- Extended storage: If corn has been in the fridge longer than the durations below, it's safer to discard it.
| Storage Type | Maximum Duration in Fridge |
|---|---|
| Fresh corn (whole, in husk) | 1-3 days |
| Fresh corn (husked) | 1-2 days |
| Cooked corn | 3-5 days |

Extending Corn's Shelf Life
Tips for Prolonging Freshness
- Refrigerate promptly: Store corn in the fridge as soon as possible after purchase — cold slows the degradation process.
- Control humidity: Corn keeps best in a humid environment. A perforated plastic bag maintains moisture without trapping enough to grow mold.
- Don't wash before storing: Moisture accelerates spoilage. Wash only when you're ready to use it.
- Keep the husk on: The husk is a natural barrier that protects the kernels from drying out.
Proper Packaging, Sealing, and Labeling
How you wrap corn directly changes how long it lasts. Unwrapped ears dry out in 1-2 days, while wrapped or sealed corn holds several days longer:
| Packaging Method | Shelf Life in Fridge |
|---|---|
| Unwrapped corn on the cob | 1-2 days |
| Wrapped corn on the cob (plastic wrap/foil) | Up to 3 days |
| Airtight container or sealed plastic bag (cooked corn) | 3-5 days |
| Vacuum sealed | Longest fridge hold; best prep for freezing |
- Sealing: Use airtight containers or resealable plastic bags to block air and excess moisture — the two main causes of spoilage.
- Vacuum sealing: Removing all air extends freshness further and prevents freezer burn if you freeze.
- Labeling: Date every container or bag so you can track how long the corn has been stored and use the oldest first.

FAQs about Corn Storage
How long does cooked corn on the cob last in the fridge?
Cooked corn on the cob — boiled or grilled — lasts 3 to 5 days in the refrigerator when stored in an airtight container or wrapped tightly in foil or plastic wrap. Corn salad or salsa keeps 3 to 4 days.
| Type of Cooked Corn | Refrigerator Shelf Life |
|---|---|
| Grilled or boiled corn | 3-5 days |
| Corn salad or salsa | 3-4 days |
| Creamed corn | 3-4 days |
How long is creamed corn good for in the fridge?
Creamed corn is good for 3 to 4 days in the fridge in an airtight container. Discard it if the cream separates or it develops a sour smell. Frozen, creamed corn keeps 8-12 months at best quality.
How long is frozen corn good for — and does frozen corn go bad?
Blanched frozen corn is at its best for 8 to 12 months in the freezer. It stays safe longer if kept frozen, but quality declines: air in the packaging causes freezer burn, and flavor and texture fade. Remove as much air as possible when packaging and date every bag.
How long is cooked frozen corn good for in the fridge?
Once frozen corn has been cooked, treat it like any other cooked corn: 3 to 5 days in the refrigerator in an airtight container.
Can you freeze fresh corn on the cob?
Yes. Blanch the ears in boiling water for 4-6 minutes, cool them in ice water, and dry thoroughly before sealing in a freezer-safe bag or container. Properly stored, it keeps its best quality for 8-12 months.
Does fresh corn have to be refrigerated?
Yes — refrigerate fresh corn as soon as possible after purchase. Cold slows the spoilage process and the conversion of sugars to starch, so refrigerated corn stays sweeter and firmer. At room temperature, corn loses quality within hours rather than days.
Why is my corn turning red in the fridge?
A red or pink tint on refrigerated corn is a form of discoloration — the same category of spoilage signal as dull, brown, or dark-spotted kernels. Discolored corn should be discarded, especially if it is accompanied by a sour smell, sliminess, or any mold.
Is it safe to eat corn past its expiration date?
It is generally not recommended, due to the risk of spoilage and foodborne illness. Check for a sour smell, slimy texture, or mold growth — if any are present, discard the corn.
