Caesar salad dressing is a popular condiment that can complement a variety of salads, wraps, sandwiches and more. Many people enjoy making Caesar dressing from scratch at home because it allows them to control the ingredients and tweak the flavor to their liking. However, homemade dressings don’t contain the same preservatives as store-bought versions. This leads to the question – does homemade Caesar dressing go bad?
Does homemade Caesar dressing go bad?
Yes, homemade Caesar dressing does eventually go bad and should not be kept indefinitely. Like any perishable food item, Caesar dressing has a limited shelf life. How quickly it spoils depends on several factors:
- Ingredient quality – Fresh, high-quality ingredients last longer.
- Storage method – Proper refrigeration extends shelf life.
- Exposure to air – Minimal air exposure prevents oxidation.
- Acidity level – Higher acidity preserves dressing longer.
When stored optimally, homemade Caesar dressing will stay fresh in the refrigerator for 5-7 days. With improper handling, it may start spoiling in as little as 2-3 days. Paying attention to signs of spoilage and following best practices when making and storing Caesar dressing can help maximize its shelf life at home.
How to tell if homemade Caesar dressing has gone bad
Here are some signs that indicate your homemade Caesar dressing has spoiled and should be discarded:
- Change in consistency – Fresh dressing is thick and creamy. As it goes bad, it becomes thin, watery or curdled.
- Mold growth – Mold is perhaps the most obvious indicator of spoiled dressing. You may see fuzziness on the surface or greenish-black spots.
- Unpleasant odor – Rancid, sour or “off” smells mean the dressing has gone bad.
- Off tastes – An acidic, bitter, or other foul taste is a sign of spoilage.
- Discoloration – Changes in the color of the dressing, like gray, yellow or brown hues, indicate it has gone bad.
If your homemade Caesar dressing displays any of these characteristics, play it safe and throw it out. Consuming spoiled Caesar dressing could potentially cause foodborne illness.
How long does homemade Caesar dressing last in the fridge?
The shelf life of homemade Caesar salad dressing depends largely on storage conditions:
- Refrigerator (40°F or below) – 5 to 7 days
- Freezer (0°F or below) – 2 to 3 months
To maximize freshness, store your homemade Caesar dressing in an airtight container in the back of the refrigerator, where temperatures are coldest. If you won’t use it within a week, consider freezing the dressing in ice cube trays or freezer bags for longer term storage.
Factors impacting homemade Caesar dressing shelf life
Several factors influence how long your homemade Caesar dressing will stay fresh and safe to eat:
- Ingredient quality – Fresh, high-quality ingredients like eggs, oil, lemon juice, and Parmesan cheese last longer than old or questionable ingredients.
- Acidity level – The lemon juice, vinegar or other acids help preserve the dressing. Higher acidity prolongs shelf life.
- Storage container – An airtight container prevents oxidation and contamination.
- Refrigerator temperature – Consistent fridge temps below 40°F slow spoilage.
- Exposure to air – Minimal headspace and limited openings minimize air exposure and oxidation.
Following best practices when making, handling and storing your homemade Caesar dressing can maximize its freshness and shelf life.
How to store homemade Caesar dressing
Here are some tips for safely storing your homemade Caesar dressing:
- Make the dressing in a clean bowl using fresh, high-quality ingredients.
- Transfer to an airtight glass or plastic container. Leave minimal headspace.
- Seal the container and refrigerate within 2 hours of making.
- Store in the back of the fridge, where temperature is coldest.
- Clearly label container with date made or use-by date.
- Use within 5-7 days for peak freshness.
- Don’t return any spoons or other utensils that touched the dressing back into the container.
- Freeze dressing in ice cube trays or bags to extend shelf life, if desired.
Following proper refrigeration and food safety practices helps homemade Caesar dressing stay fresh as long as possible.
Can you freeze homemade Caesar dressing?
Yes, freezing is an excellent way to extend the shelf life of homemade Caesar dressing. To freeze:
- Make the dressing fresh and store in an airtight container as usual.
- Refrigerate for up to 2 days maximum before freezing.
- Transfer dressing to ice cube trays or small freezer bags.
- Press out air, seal trays/bags, and label with date.
- Freeze at 0°F or below for up to 2-3 months.
- Thaw cubes or portions in the refrigerator when ready to use.
- Use thawed dressing within a few days.
Freezing prevents bacterial growth by halting spoilage reactions. With proper handling, frozen homemade Caesar dressing stays safe and retains its flavor for months.
How long does Caesar dressing last after opening?
Once opened, homemade Caesar dressing should be used within:
- Refrigerator: 5-7 days
- Freezer: 2-3 months (if frozen immediately after opening)
Discard any dressing that sits at room temperature for over 2 hours after opening. To maximize shelf life after opening, transfer dressing to an airtight container, seal tightly, and refrigerate immediately.
Can you eat spoiled Caesar dressing?
It is not recommended to knowingly eat Caesar dressing that has spoiled. Consuming spoiled foods can potentially cause foodborne illness. Symptoms may include nausea, vomiting, stomach cramps, and diarrhea.
The high-risk ingredients in Caesar dressing that are prone to spoilage are raw eggs, dairy products, and garlic. These items can grow dangerous bacteria when left at unsafe temperatures for too long. Even if the dressing doesn’t look or smell bad, harmful pathogens may be present. Don’t eat Caesar dressing past its use-by date or if it shows any odd characteristics. When in doubt, throw it out.
