Ranch dressing is a popular condiment made from a mixture of buttermilk, cream, and spices. While ranch dressing is typically safe to eat, a few things can cause it to go bad.

If the dressing is left out of the fridge for more than two hours, bacteria can start to grow, potentially leading to food poisoning. 

Similarly, if the dressing is not properly sealed, it can spoil. Finally, if the expiration date on the bottle has passed, it is best to discard the dressing. 

However, as long as ranch dressing is stored properly and not past its expiration date, it should be safe to eat.

Does It Need To Be Refrigerated?

Ranch dressing is a popular condiment for salads, pizzas, and dips. But does it need to be refrigerated?

Most commercial brands of ranch dressing contain preservatives that allow them to be stored at room temperature.

However, if you make your ranch dressing or purchase a brand that doesn’t contain preservatives, it’s important to refrigerate it. Bacteria can grow quickly in mayonnaise-based sauces, so it’s best to keep them cool.

When ready to use it, thaw the dressing in the refrigerator overnight. You can also use frozen Ranch dressing as a base for dips or sauces.

How To Know If Ranch Is Spoiled 

The first step is to check the expiration date. Even if it hasn’t expired, ranch dressing can spoil if it isn’t stored properly. It should be kept in a cool, dry place and tightly sealed when not in use. 

If the dressing has been stored properly and is still within the expiration date, there are a few other indicators that it has gone bad.

The color may change from white to yellow, and the texture may become lumpy. The dressing may also develop an unpleasant odor. 

If you notice any of these changes, throwing the ranch away is best.


Can we make a homemade Ranch?

Yes, you can make homemade ranch dressing.

Mix 1 cup of buttermilk, 1/2 cup of mayonnaise, 2 tablespoons of white vinegar, 1 tablespoon of minced fresh parsley, 1 tablespoon of minced fresh chives, 1 tablespoon of minced fresh dill weed, 1 teaspoon of salt, and 1/2 teaspoon of ground black pepper in a bowl. 

Pour the mixture into a jar with a tight-fitting lid and refrigerate for at least 4 hours before using.

How long can homemade ranch dressing sit out?

Homemade ranch dressing can sit out for up to two days. After that, it should be discarded because bacteria will start to grow.

What is the difference between a store-bought and a homemade Ranch?

The biggest difference between store-bought ranch and homemade ranch is the absence of processed ingredients in the latter.

Most store-bought ranch dressings contain unhealthy additives, such as high fructose corn syrup, MSG, and artificial colors and flavors.

Does sealed ranch ever go bad?

Yes, a sealed ranch will eventually go bad. The preservatives in the sauce will eventually expire, and it will start to spoil.

If you’re not going to use it all right away, transfer it to a smaller container and keep it in the fridge.

Final Thoughts

The answer to this question is a little complicated. It depends on the type of ranch dressing, how it was made, and how long it’s been left out.

Generally speaking, though, most ranch dressings will last for about two weeks if stored in the fridge. 

If they’re left out at room temperature, that time frame shortens to about one week. However, some variations of ranch dressing can be stored unrefrigerated for up to six months. 

If you have any doubts about whether your ranch has gone bad or not, it’s always best to play it safe and throw it away.
