How Long Does Boxed Chicken Broth Last Unopened

Boxed chicken broth is a versatile kitchen staple that can add depth and flavor to a wide range of dishes, from soups and stews to sauces and risottos. But if you’ve ever reached for a carton of chicken broth at the back of your pantry and wondered, “How long has this been here?” you’re not alone. Understanding the shelf life of boxed chicken broth, particularly when it’s unopened, is essential to ensure you’re using safe and flavorful ingredients in your cooking.

Understanding Expiration Dates

Before we delve into the specifics of how long boxed chicken broth lasts unopened, let’s talk about expiration dates. Many food products, including chicken broth, come with a printed expiration date. This date is a rough estimate of when the product is at its peak quality, and it’s generally a conservative estimate to ensure consumer safety.

Factors Affecting Shelf Life

You’ve accurately highlighted the key factors that can significantly affect the shelf life of boxed chicken broth. Let’s delve a bit deeper into each of these factors:


The choice of packaging material is crucial in determining the shelf life of chicken broth. Most boxed chicken broth is packaged in aseptic cartons, which are designed to provide an excellent barrier to air and light. This airtight and light-resistant packaging plays a pivotal role in preserving the quality and freshness of the broth. It prevents oxygen from entering, which can cause spoilage and the development of off-flavors. Additionally, it shields the broth from harmful UV rays, further enhancing its longevity.

Storage Conditions

Temperature and humidity are critical environmental factors that can either extend or shorten the shelf life of chicken broth. Storing unopened cartons of chicken broth in a cool, dry place is essential. A temperature below 85°F (29.4°C) is optimal for maintaining the quality of the broth. Exposing the broth to excessive heat or humidity can accelerate the breakdown of its components, leading to spoilage and a shorter shelf life.

Quality of Ingredients

The quality of the ingredients used in making chicken broth plays a significant role in determining how long it remains safe and flavorful. Broths made from high-quality, fresh ingredients tend to have a longer shelf life compared to those made from lower-quality components. Fresh ingredients typically contain fewer contaminants and microorganisms, reducing the risk of spoilage.


Some commercial chicken broths may contain preservatives or additives that are specifically included to extend their shelf life. These additives can inhibit the growth of bacteria and other microorganisms that cause food to spoil. While additives can be effective in prolonging shelf life, it’s essential to read the product label if you have specific dietary preferences or restrictions.

Storage Conditions

To maximize the shelf life of your boxed chicken broth, follow these storage tips:

  • Keep it in a cool, dry place, away from direct sunlight and heat sources.
  • Ensure the carton is tightly sealed to prevent air from entering.
  • Check the pantry temperature; it should be below 85°F (29.4°C) for optimal shelf life.

Determining Spoilage

Even though boxed chicken broth is known for its durability, it can eventually go bad. Signs of spoilage include an off smell, a change in color or texture, or the presence of mold. If you notice any of these signs, it’s best to discard the broth.

Extending Shelf Life

To get the most out of your unopened boxed chicken broth, consider these tips:

  • Buy broth with the furthest expiration date available.
  • Rotate your pantry stock, using older cartons first.
  • Consider freezing unopened cartons to extend shelf life further.

Uses for Expired Chicken Broth

If you find yourself with chicken broth that’s past its prime, don’t throw it away just yet. You can still use it for various purposes, such as:

Cooking Rice: Use chicken broth instead of water to infuse flavor into your rice dishes.

Marinades: Create flavorful marinades for meats and vegetables.

Sauces: Incorporate expired broth into sauces and gravies.

Soups and Stews: Simmering vegetables and meats in broth can mask any off-flavors.

Fertilizer: Diluted, expired chicken broth can even be used as a fertilizer for your plants.
