Can you freeze beef stroganoff with the sour cream in it?

Quick Answer

Yes, you can freeze beef stroganoff with sour cream in it. Sour cream is a dairy product that freezes well and will not curdle or separate when thawed after freezing. The key is to make sure the sour cream is thoroughly incorporated into the stroganoff before freezing. Freezing beef stroganoff with sour cream allows you to make a large batch ahead of time so you can enjoy this delicious dish whenever you want with minimal effort.

Does Sour Cream Freeze Well?

Sour cream is able to be frozen because of its fat content and acidic nature. The fat content (usually 18-20%) creates a protective barrier around the cream particles during freezing. This prevents large ice crystals from forming and damaging the cream’s texture.

The acidic environment of sour cream (pH of 4.5 or below) also helps the proteins and fats resist breakdown during freezing. As long as air is pressed out before freezing, sour cream maintains its thick, creamy texture when thawed after freezing.

Freezing does not kill the beneficial bacteria cultures in sour cream either. The cold temperature simply puts the bacteria in an inactive state. When thawed, the cultures reactivate and sour cream regains its tangy flavor.

So not only can you freeze sour cream on its own, you can safely freeze recipes containing sour cream without the texture or taste deteriorating.

Freezing Beef Stroganoff with Sour Cream

Beef stroganoff is a Russian dish of sliced beef cooked in a rich, creamy sauce with mushrooms and onions. Recipes typically call for sour cream to be stirred in at the end to finish the sauce.

Follow these tips for best results freezing beef stroganoff with sour cream:

1. Choose an appropriate recipe

Look for beef stroganoff recipes developed to be freezer-friendly. These will contain a sufficient amount of liquid or sauce to keep the mixture from drying out in the freezer. Recipes with about 1 cup sour cream per 3-4 servings work well.

2. Cook the beef fully

It’s important the sliced beef is cooked through before freezing. Raw or undercooked beef may become tough and dry when frozen. Cook the beef until no longer pink.

3. Cool completely before adding sour cream

Wait until the stroganoff is cooled to room temperature before stirring in the sour cream. Adding sour cream to hot liquid can cause it to curdle or separate.

4. Mix in the sour cream thoroughly

Use a spatula to fully incorporate the sour cream so no pockets of just sour cream remain. This ensures the sauce freezes evenly.

5. Chill before freezing

After adding the sour cream, refrigerate the beef stroganoff for 1-2 hours uncovered so it cools further. Then cover and freeze. Going straight from hot to frozen can create ice crystals.

6. Freeze in portions

Divide the beef stroganoff into single serving or family-sized portions in freezer bags or containers before freezing. This allows for easy reheating. Flatten bags to freeze flat.

7. Remove as much air as possible

Use the water displacement method or a vacuum sealer to suck out excess air from bags. Air can cause freezer burn. For containers, leave 1⁄2 to 1-inch headspace.

8. Freeze for up to 2-3 months

Store frozen beef stroganoff with sour cream for maximum quality for 2-3 months at 0°F or below. Label bags or containers with contents and date.

9. Thaw in the refrigerator

For food safety, always thaw beef stroganoff in the refrigerator overnight rather than at room temperature. This helps prevent bacterial growth.

10. Simmer to reheat

Reheat thawed beef stroganoff gently over low heat on the stovetop while stirring occasionally until heated through. Add a splash of milk or broth if the sauce seems too thick. Avoid boiling to prevent curdling the sour cream.

Storage Considerations

Follow proper storage methods to maintain quality of frozen beef stroganoff with sour cream:

  • Use moisture-proof freezer bags, plastic containers, or aluminum foil to prevent freezer burn.
  • Wrap tightly and press out excess air.
  • Don’t overfill bags or containers, leave headspace for expansion.
  • Avoid opening the freezer frequently to limit temperature fluctuations.
  • Store at 0°F or colder for longest shelf life.

Signs of Freezer Burn

Check frozen beef stroganoff with sour cream periodically for signs of freezer burn:

  • Dry, flaky spots on the surface
  • Changes in color from bright to dull or grayish
  • Ice crystals or a dried out, spongy texture
  • Off odors, flavors, or the taste of rancid fats

Freezer burned portions should be trimmed before reheating. Prevent freezer burn by keeping air exposure to a minimum.

Can You Refreeze Thawed Beef Stroganoff?

Previously frozen beef stroganoff that has been properly thawed in the refrigerator can be safely refrozen without compromising quality. Make sure the beef stroganoff remains chilled below 40°F throughout the thawing process.

To refreeze:

  • Check for off colors, odors, or texture changes.
  • Bring the beef stroganoff mixture back up to temperature by simmering on the stove until steaming hot throughout.
  • Cool back down before returning to freezer.
  • Refreeze within 1-2 days for best quality.
  • Only refreeze once.

This reheating step helps destroy any bacteria that may have developed during initial thawing. Refreezing thawed beef stroganoff that was left at room temperature for over 2 hours is not recommended.

Can You Freeze Sour Cream By Itself?

It’s easy to freeze extra sour cream to extend its shelf life beyond the typical 2-3 weeks. Here’s how:

1. Check expiration date

Freeze sour cream by the “sell by” or “best by” date, not after it expires. Sour cream lasts about 2-3 weeks after the sell by date if refrigerated.

2. Stir before freezing

Give the carton a good stir to reincorporate any liquid separation that has occurred during refrigerated storage.

3. Portion into freezer bags or containers

Divide sour cream into usable amounts like 1 or 2 cups rather than freezing the whole carton. Smaller packages thaw faster. Flatten bags to freeze flat. Allow headspace in containers.

4. Remove air

Use a vacuum sealer or the water displacement method to remove as much air as possible before sealing bags. Air causes freezer burn.

5. Freeze for up to 2 months

Store frozen sour cream at 0°F or below for optimal quality, using within 2 months. Label packages with contents and freeze date.

6. Thaw overnight in the fridge

To prevent curdling, thaw frozen sour cream gradually in the refrigerator. Gently stir after thawing to evenly distribute moisture.

7. Use thawed sour cream within 1 week

Use thawed sour cream within a week for best flavor, texture, and freshness. Do not refreeze thawed sour cream. Discard if mold forms.
