Safe, but quality has slipped

Staying frozen solid keeps food safe with no time limit, but by 12 months you can expect flat flavor and some freezer burn. Use it in soups, sauces or baking, and cut away any dry gray patches.

Background

Getting to know bacon grease

Bacon grease sits in the condiments & sauces section of our food guide. Going by USDA FoodKeeper, it lasts 6 months in the fridge and 12 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.

Straight answers

Your bacon grease storage questions

How long does bacon grease last in the fridge?

6 months when held at 4°C (40°F) or below. Seal it well so it stays free of moisture and fridge odors.

How long does bacon grease last in the freezer?

12 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 bacon grease last at room temperature?

Room-temperature storage does not suit it; keep it in the fridge.

How long is bacon grease good after the expiration date?

Bacon grease kept in good conditions is generally still safe after its best-by date. Before use, inspect the odor, appearance and flavor.

How do you know if bacon grease 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.

Before you take a bite

How to spot spoiled bacon grease

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.

Inspect your bacon grease and tick each warning sign you see

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's happening

What makes bacon grease 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 bacon grease

  • 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 bacon grease?

Yes — it freezes wellHeld at 0°F / -18°C, it keeps its best quality for roughly 12 months. Food that stays frozen remains safe indefinitely; only the quality slips over time.
  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.

Defrosting

Safe ways to defrost bacon grease

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.

Room temperature · 2-hour rule

Bacon grease left out overnight

Bacon grease is low-risk, yet a night on the counter eats into its remaining fridge time. Put it back in the cold and plan to finish soon.

How to store it

Keeping bacon grease 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 bacon grease packaging mean

Best-by vs. sell-by

Counting from the purchase date, FoodKeeper allows unopened bacon grease 6 months 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

Bacon grease kept in good conditions is generally still safe after its best-by date. Before use, inspect the odor, appearance and flavor.

Shopping

Choosing good bacon grease 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

Bacon grease: 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.

Bacon grease myths: fact or fiction?

  1. 1.As long as it smells okay, bacon grease is still safe after being refrigerated longer than 6 months.
    You got it!
    Not this time.

    Partly true. Because bacon grease is low-risk, going slightly beyond 6 months usually costs quality rather than safety. Look for mold and sniff for off odors first.

  2. 2.Putting bacon grease in the freezer kills any bacteria on it.
    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.Bacon grease holds up well in the freezer.
    You got it!
    Not this time.

    True. Held at 0°F / -18°C, it keeps its best quality for roughly 12 months. Food that stays frozen remains safe indefinitely; only the quality slips over time.

  4. 4.Bacon grease 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.Bacon grease has to go in the fridge to stay safe.
    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.

Reader questions

Bacon grease: frequently asked questions

How long does bacon grease last in the fridge?
Bacon grease lasts 6 months when refrigerated at 40°F (4°C) or colder. That figure comes from USDA FoodKeeper.
Can you freeze bacon grease?
Yes, you can. Held at 0°F / -18°C, it keeps its best quality for roughly 12 months. Food that stays frozen remains safe indefinitely; only the quality slips over time.
How can you tell if bacon grease has 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.
Does bacon grease go bad after the printed date?
Bacon grease kept in good conditions is generally still safe after its 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 bacon grease?
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 6 months fridge window for bacon grease.
What should I store bacon grease 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 bacon grease?
Yes. Although the door is the warmest spot in the fridge, bacon grease holds up against spoilage well enough to live there. Seal the lid firmly every time you use it.
Can you refreeze bacon grease?
Yes, but only when it defrosted in the refrigerator and has 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 bacon grease?
No. At -18°C (0°F), bacteria stop multiplying, but they aren't killed off. Once bacon grease thaws, 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 bacon grease smells okay but is beyond the storage time, is it still safe?
With a low-risk food such as bacon grease, 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 it if anything seems wrong.
