Background

Getting to know marinated vegetables in oil

Marinated vegetables in oil sit in the vegetables section of our food guide. The USDA FoodKeeper database files them under the name “Marinated vegetables (in oil)”. Going by USDA FoodKeeper, they last 3–4 days in the fridge. They fall into the lower-risk group, so storing them 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.

What's happening

What makes marinated vegetables in oil 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.

Don't do this

Mistakes people make storing marinated vegetables in oil

  • 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.
Freezer

Can you freeze marinated vegetables in oil?

No FoodKeeper timeFoodKeeper does not list a freezer time for marinated vegetables in oil.
  1. 1Step 1

    Freezing usually isn't necessary; most condiments hold up well in the fridge.

  2. 2Step 2

    If you do freeze it, use small containers or an ice-cube tray, and label them.

  3. 3Step 3

    Defrost it in the fridge and stir thoroughly; emulsified sauces can split.

Room temperature · 2-hour rule

Marinated vegetables in oil left out overnight

Marinated vegetables in oil are low-risk, yet a night on the counter eats into their remaining fridge time. Put them back in the cold and plan to finish soon.

How to store it

Keeping marinated vegetables in oil 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.
Package dates

What the dates on marinated vegetables in oil packaging mean

Best-by vs. sell-by

Counting from the purchase date, FoodKeeper allows unopened marinated vegetables in oil 3–4 days in the refrigerator. 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.

Past the printed date

Marinated vegetables in oil kept in good conditions are generally still safe after their best-by date. Before use, inspect the odor, appearance and flavor.

Shopping

Choosing good marinated vegetables in oil 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.
Waste less

Marinated vegetables in oil: ways to finish them in time

  • Mark the date you opened it on the lid.
  • Scrape the last bit of a jar into a dressing, sauce or marinade.

Test yourself

Marinated vegetables in oil myths: fact or fiction?

  1. 1.As long as they smell okay, marinated vegetables in oil are still safe after being refrigerated longer than 3–4 days.
    You got it!
    Not this time.

    Partly true. Because marinated vegetables in oil are low-risk, going slightly beyond 3–4 days usually costs quality rather than safety. Look for mold and sniff for off odors first.

  2. 2.Putting marinated vegetables in oil in the freezer kills any bacteria on them.
    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.

  3. 3.Marinated vegetables in oil hold up well in the freezer.
    You got it!
    Not this time.

    Partly. FoodKeeper does not list a freezer time for marinated vegetables in oil.

  4. 4.Marinated vegetables in oil can be kept in the fridge door.
    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.

  5. 5.Marinated vegetables in oil have to go in the fridge to stay safe.
    You got it!
    Not this time.

    Not for safety reasons, but refrigeration keeps them at peak quality for longer. Go by the storage times listed on this page.

Reader questions

Marinated vegetables in oil: frequently asked questions

How long do marinated vegetables in oil last in the fridge?
Marinated vegetables in oil last 3–4 days when refrigerated at 40°F (4°C) or colder. That figure comes from USDA FoodKeeper.
Can you freeze marinated vegetables in oil?
FoodKeeper does not list a freezer time for marinated vegetables in oil.
How can you tell if marinated vegetables in oil have gone bad?
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.
Do marinated vegetables in oil go bad after the printed date?
Marinated vegetables in oil kept in good conditions are generally still safe after their best-by date. Before use, inspect the odor, appearance and flavor.
What is the source for these storage times?
They come from USDA FoodKeeper, the food storage database run by the USDA Food Safety and Inspection Service (FSIS). We last checked this page against the current FoodKeeper release.
What temperature is best for storing marinated vegetables in oil?
Set the fridge to 4°C (40°F) or below and the freezer to -18°C (0°F). The dial on a lot of fridges is optimistic and the real temperature runs higher, so a cheap appliance thermometer is money well spent. A fridge running even a few degrees above 4°C will noticeably eat into the 3–4 days fridge window for marinated vegetables in oil.
What should I store marinated vegetables in oil in?
Use the original jar or bottle with the lid on tight; move opened canned food into a covered container. You want to block air and moisture, keep smells from traveling to other food, and be able to tell at a glance how old the food is. Jot the date on the lid or on a label so there is never any guesswork about its age.
Is the fridge door a good spot for marinated vegetables in oil?
Yes. Although the door is the warmest spot in the fridge, marinated vegetables in oil hold up against spoilage well enough to live there. Seal the lid firmly every time you use them.
Can you refreeze marinated vegetables in oil?
Yes, but only when they defrosted in the refrigerator and have not sat out at room temperature. Anything defrosted in the microwave or a cold-water bath needs to be cooked before it goes back into the freezer. Quality drops a little with every freeze-and-thaw round, so freeze in portions you'll use in one go.
Does freezing kill bacteria in marinated vegetables in oil?
No. At -18°C (0°F), bacteria stop multiplying, but they aren't killed off. Once marinated vegetables in oil thaw, any bacteria that were there wake up again, so defrost in the fridge and, where relevant, bring it up to a safe temperature when you cook or reheat it.
If marinated vegetables in oil smell okay but are beyond the storage time, are they still safe?
With a low-risk food such as marinated vegetables in oil, going beyond the storage time generally affects quality rather than safety. Look for mold, sniff for off odors and notice any strange taste, and get rid of them if anything seems wrong.
