Ranch Dressing Shelf Life: Can It Go Bad or Expire? How Long Does It Last?

The ranch is a US favorite! People eat it with almost any food and never get enough of it. A typical American household is kinda not complete if you can’t find a bottle of ranch salad dressing in their kitchen. So, does ranch dressing go bad?

Yes, the ranch does go bad, but it can last for at least a year if you don’t open the bottle yet. Once opened, you can even keep it for a few months.

That’s the case for the store-bought ranches, as they contain many stabilizers and preservatives to help extend their shelf life. If you have a homemade ranch, the shelf life is shorter.

In this post, we’ll discuss the answers to these questions about the ranch:

What Is Ranch?

Ranch, ranch salad dressing, or ranch sauce is a famous type of salad dressing that has a combination of smoothly whisked mayonnaise, sour cream, milk, chives, onions, dill parsley, garlic powder, onion powder, salt, and pepper.

There are at least 2 versions of the ranch; one with a thicker consistency that serves as a salad dip while the thinner one serves as a salad dressing.

It also pairs well with vegetables such as celery, spinach, arugula, and more. Furthermore, it’s not a surprise that it has become of the daily life of many people’s meals!

Store-bought ranch

Note that the shelf life of your store-bought ranch will depend on the ingredients it contains. Hence, some varieties can last for a few months, and some can stay for at least a year.

Store-bought ranch dressing contains preservatives and stabilizers, which can help them last for about 12 to 18 months at room temperature.

Once opened, it can last in the fridge for about 6 months.

Homemade ranch

Freshly made ranch dressing or homemade ranch can only last for up to 4 days to two weeks in the refrigerator.

If it has more dairy ingredients, it may only last for 2 hours at room temperature. That’s why you should only produce homemade ranch in small batches to minimize food waste.

Does Ranch Dressing Go Bad? How To Tell For Sure

Eating a spoiled ranch definitely is not something you want to happen. So how can you tell if your ranch has already gone bad?

Here’s what you should do to detect a spoiled ranch.

1. Inspect the appearance of your ranch dressing.

If you notice if the color is different from the time you bought it, that’s already a sign of spoilage. There’s no need for you to taste it; just throw it away immediately.

If you see some fuzzy molds feasting on your ranch, don’t ever think of scraping off the affected part and believe it is okay to eat the “clean” portion.

You can never tell with your naked eyes if that part was already contaminated with mold spores that are just waiting for the right timing and environmental condition to sprout.

We advise that you discard it to avoid the dangers of foodborne illness for your safety.

2. Check the odor

Give your ranch a sniff and find out if it smells okay. If it comes off with an odorous or sour smell, that already indicates that it’s no longer safe to eat. Thus, you should toss it away.

3. Check the condition of the packaging or bottle.

If you have a bloated bottle of ranch, you should never eat the contents.

A bloated or bulging container is a sign that foodborne pathogens are actively thriving in the container. Thus, you should not feel bad about throwing it away. (*)
