Au jus is a popular condiment and sauce that is commonly served with prime rib or roast beef.
It is made by adding water or broth to pan drippings and simmering for a period of time.
While Au jus can add flavor and depth to dishes, it’s imperative to understand its shelf life and when it goes bad.
The critical question that arises here is, how long does au jus last, and does it go bad?
This article will go in-depth about the shelf life of Au jus, the factors that impact its longevity, and how to tell when it has gone bad.
What is Au Jus?
Au jus is a French term for “with juice.” It’s a term used to describe beef broth or sauce that is served with roasted meat. This sauce takes its flavor and coloring from the pan drippings, which give it a rich and savory flavor.
The sauce is typically made by reducing beef broth or water that has been infused with spices and roasted meat’s juices. It is commonly used as a condiment for beef dishes like prime rib, roast beef, or French dip sandwiches.
Au jus is the perfect accompaniment for roasted meats and helps reduce their dryness. It can also enhance other dishes’ flavor and act as a dip for bread or vegetables, making it a versatile option in the kitchen.
How Long Does Au Jus Last?
The shelf life of au jus is dependent on several factors, including its ingredients, storage conditions, and whether it has been opened or not. Generally speaking, a homemade Au jus can last for up to four days in the refrigerator if kept in an airtight container or a tightly sealed jar.
However, it’s important to note that this is only an estimate, and several factors can influence its shelf life.
While Au jus can last up to four days, it is best to consume it as soon as possible for the best flavor. The longer the Au jus sits, the more its flavor profile changes, leading to degradation in the quality.
Opened Au Jus
Once you have opened the au jus, you should consume it within four days for the best taste. When storing the opened au jus, ensure that it is at a temperature of 40°F or lower. If left in freezer storage, it should be consumed within three months.
Unopened Au Jus
If it’s an unopened container, the Au jus will last longer. Generally, it can last up to six months in the pantry if stored under ideal conditions. So, pay attention to the expiration date and make sure that you store it correctly.
The longevity of unopened Au jus is more than opened Au jus because the seal on the container restricts air and bacteria to enter, which helps to keep it fresh longer.
Factors That Impact the Shelf Life of Au Jus
Several factors can impact the shelf life of Au jus. Below are some of the more important factors.
The ingredients that go into the Au jus play a significant role in determining its shelf life. If the recipe calls for the use of preservatives or additives, the Au jus might last longer than homemade ones.
Preservation is another vital factor that determines Au jus’ shelf life. How you store the Au jus can significantly impact its longevity. Fresh Au jus will always have a shorter shelf life than commercially produced ones, which have more preservatives and additives.
Au jus must be kept at a stable temperature to prevent bacterial growth. A cool and dry environment is the best for Au jus storage.
Exposure to Air
Air exposure is not something that you want when storing Au jus. The more air that comes into contact with the Au jus, the higher the chances of bacterial growth. This will increase the speed at which the Au jus will spoil.
How to Tell When Au Jus Has Gone Bad
While Au jus is delicious and flavorful, it does have a shelf life, and it’s important to know when it has gone bad. Below are the signs you should look out for;
If the Au jus has gone bad, it will produce a sour or pungent odor that is indicative of bacterial growth. The bad smell is one of the most significant signs that Au jus has gone bad.
The appearance of the Au jus can also show whether it has gone bad or not. If the sauce becomes cloudy or there are visible signs of mold growth, it’s time to dispose of it.
If the Au jus has a sour or bitter taste, it’s a clear indication that it has gone bad and should be disposed of immediately.
How to Store Au Jus
The best way to store Au jus is by refrigeration, and it’s essential to keep it at a consistent temperature. Below are some guidelines on how to store Au jus:
Refrigeration is the best way to keep Au jus fresh and safe for consumption. The recommended temperature for refrigeration is 40°F or lower.
Au jus must be stored in an airtight container or jar. This will help keep the air out and reduce the chances of bacterial growth.
You can release excess air from the container and freeze the Au jus in an ice-cube tray. This is a great way to keep Au jus fresh for a more extended period. When freezing, ensure that you use a tightly sealed container or a freezer bag.
In summary, Au jus is a delicious accompaniment to roasted meats that can elevate the flavor of any dish. When it comes to its shelf life, it’s always better to be on the safe side and consume it within four days of opening.
If you have an unopened container of Au jus, you can store it for an extended period as long as you keep it in ideal storage conditions. When Au jus goes bad, it will produce a sour or rancid smell, and mold may start to grow. To enjoy Au jus at its best, keep it refrigerated in an airtight container and consume it as soon as possible.
