Test the timing on your tomato paste
Comfortably within the 27 months pantry time for tomato paste, provided it has been stored somewhere cool and dry with the lid sealed.

Beyond the 27 months pantry time. Shelf-stable foods tend to lose quality rather than turn unsafe; discard it if you notice mold, pests, damp clumps or a bad smell.

We assume a dark, dry, cool cupboard and a package that's sealed tight.
Held at -18°C (0°F), tomato paste is comfortably inside the 2–3 months quality window. Defrost in the fridge, then use it over the following day or two.
Safe, though it is reaching the end of peak quality. Plan to use it within a few weeks, since flavor and texture decline after 2–3 months.
Staying frozen solid keeps food safe with no time limit, but by 6 months you can expect flat flavor and some freezer burn. Use it in soups, sauces or baking, and cut away any dry gray patches.
Staying frozen solid keeps food safe with no time limit, but by 9 months you can expect flat flavor and some freezer burn. Use it in soups, sauces or baking, and cut away any dry gray patches.
Based on a freezer running at -18°C (0°F) or below. Food kept frozen remains safe, so these results describe quality only.
How long tomato paste keeps with each storage method
| Storage | How long | Temp | Packaging | Good to know |
|---|---|---|---|---|
| Refrigerator (opened) | 5 days | ≤ 40°F / 4°C | Airtight | 40°F (4°C) or colder |
| Freezer (opened) | 2–3 months | 0°F / -18°C | Wrapped or freezer bag | 0°F; for quality, not safety |
| Counter / pantry (unopened) | 27 months | 68–72°F | Airtight | kept cool and dry |
Getting to know tomato paste
Tomato paste sits in the pantry staples section of our food guide. Going by USDA FoodKeeper, it lasts 5 days in the fridge and 2–3 months in the freezer. It falls into the lower-risk group, so storing it well is mostly about keeping quality rather than about safety. Best storage spot: the door runs warmer than the rest of the fridge, which suits condiments and drinks that hold up well against spoiling.
Condiments, sauces and canned foods are built to keep: sealed packaging plus plenty of acid, sugar or salt holds microbes at bay. Unopened, most last for months or even years in the pantry. After opening, crumbs off utensils, moisture and air find their way in, and most then need refrigeration and have a much shorter shelf life.
The best place for tomato paste

Your tomato paste storage questions
How long does tomato paste last in the fridge?
5 days when held at 4°C (40°F) or below (opened). Seal it well so it stays free of moisture and fridge odors.
How long does tomato paste last in the freezer?
2–3 months at -18°C (0°F) for peak quality. It remains safe for as long as it stays frozen; past that point, flavor and texture slowly decline.
How long does tomato paste last at room temperature?
Room-temperature storage does not suit it; keep it in the fridge.
How long does tomato paste last after opening?
5 days refrigerated after opening. As soon as the seal is broken, the date on the package no longer counts.
How long does unopened tomato paste last?
27 months on a pantry shelf, provided the seal is unbroken and it is stored the way the label directs.
How long is tomato paste good after the expiration date?
Counting from the purchase date, FoodKeeper allows unopened tomato paste 27 months on the pantry shelf. Labels such as "best-by" and "sell-by" are about peak quality and how stores rotate stock, not about safety — infant formula is the one product whose use-by date federal law requires.
How do you know if tomato paste is bad?
Sour, yeasty or fermented notes that go beyond its normal tang. A slimy layer, or separation that won't stir back together. Darkening or a color shift near the top of the jar.
How to spot spoiled tomato paste
Odor
Sour, yeasty or fermented notes that go beyond its normal tang.
Texture
A slimy layer, or separation that won't stir back together.
Color
Darkening or a color shift near the top of the jar.
Mold
Fuzz on the surface or under the lid means the whole jar goes.
No boxes ticked? That's encouraging. Even so, confirm how long it has been stored, because the germs behind food poisoning can't be seen with the naked eye.
Even one of these means it has spoiled. Toss it, and never taste it to find out.
What makes tomato paste spoil
Yeasts and molds are the usual problem in opened jars, showing up as surface fuzz, bubbling or a boozy, fermented smell. Damaged cans of low-acid food pose an uncommon but dangerous botulism risk from Clostridium botulinum, so any can that bulges, leaks or is badly dented should be discarded without being opened.
Mistakes people make storing tomato paste
- Double-dipping or spreading with a used knife, which carries in crumbs and bacteria.
- Leaving an opened jar on the pantry shelf even though its label calls for refrigeration once opened.
- Storing leftovers in their opened can in the fridge; transfer them to a covered container instead.
- Using cans that are rusty, bulging or badly dented.
Can you freeze tomato paste?
- 1Step 1
Freezing usually isn't necessary; most condiments hold up well in the fridge.
- 2Step 2
If you do freeze it, use small containers or an ice-cube tray, and label them.
- 3Step 3
Defrost it in the fridge and stir thoroughly; emulsified sauces can split.
Safe ways to defrost tomato paste
In the refrigerator
Move it from freezer to fridge the evening before you need it; this preserves the texture best.
On the counter
Suitable only for shelf-stable foods; perishables should never be thawed at room temperature.
Straight from frozen
Plenty of foods can go directly into the oven, a soup, a sauce or a smoothie.
Tomato paste left out overnight
After opening, tomato paste should live in the fridge. A night at room temperature hastens spoilage, so throw it out if the smell, look or taste seems wrong.
Keeping tomato paste in good shape
- Unless the label says something different, put it in the fridge once opened.
- Dip in with a clean utensil every time; crumbs and double-dipping cut its life short.
- Wipe the rim clean and screw the lid on tight.
What the dates on tomato paste packaging mean
Before opening
Counting from the purchase date, FoodKeeper allows unopened tomato paste 27 months on the pantry shelf. Labels such as "best-by" and "sell-by" are about peak quality and how stores rotate stock, not about safety — infant formula is the one product whose use-by date federal law requires.
After opening
The printed date stops counting the moment the seal is broken. Allow 5 days in the refrigerator, starting on the day you open it.
Choosing good tomato paste at the store
- Inspect cans for swelling, rust and deep dents along the seams.
- Lids on jars should be tight, with a seal that pops the first time you twist it open.
- Choose condiment sizes you can use up within the opened window.
Tomato paste: ways to finish it in time
- Mark the date you opened it on the lid.
- Scrape the last bit of a jar into a dressing, sauce or marinade.
- Freeze leftover sauce in ice-cube trays.

Tomato paste myths: fact or fiction?
- You got it!Not this time.
Partly true. Because tomato paste is low-risk, going slightly beyond 5 days usually costs quality rather than safety. Look for mold and sniff for off odors first.
- You got it!Not this time.
False. The freezer puts bacteria on hold rather than killing them. They start up again as the food warms, so let it thaw in the fridge, then cook or reheat it all the way through.
- You got it!Not this time.
True. Held at 0°F / -18°C, it keeps its best quality for roughly 2–3 months. Food that stays frozen remains safe indefinitely; only the quality slips over time.
- You got it!Not this time.
True. The door runs warmer than anywhere else in the fridge, yet this food holds up well enough to be stored there.
- You got it!Not this time.
Not for safety reasons, but refrigeration keeps it at peak quality for longer. Go by the storage times listed on this page.
