I use boxed broth to quickly add flavor to soups, stews, braises, and other dishes when I cook at home. When I don’t have to make broth from scratch, having a carton or two of beef broth on hand saves me time and work. But I don’t go through beef broth too fast. So I wanted to know how long a carton of beef broth lasts after it’s been opened?
I’ll talk about what I found out about how long unopened boxed or cartoned beef broth can be kept. You will find out how long it stays safe to use and fresh, as well as how to store it safely. This article will tell you how long that box of beef broth can stay in the pantry before it goes bad.
Overview of Boxed Beef Broth
First, let’s take a look at what boxed beef broth is and how it’s usually stored.
Beef broth sold in cartons and boxes is commercially prepared using beef bones, meat trimmings, vegetables, and seasonings It offers convenience – just open the carton and pour it into your dish or recipe Popular brands include Swanson, College Inn, Pacific Foods, and Kitchen Basics.
The broth typically comes in aseptic shelf-stable cartons or boxes in sizes like 32 oz and 14.5 oz. The packaging keeps it fresh at room temperature until opened. Once opened, it requires refrigeration.
Unopened boxed beef broth is usually stored in the pantry. The exact shelf life varies based on the best by date and how it’s stored.
Shelf Life of Unopened Boxed Beef Broth
So how long does unopened beef broth last in the pantry? Here is an overview of the shelf life for beef broth in cartons or boxes:
- Unopened: 1 to 2 years past the “best by” date on the package when stored properly.
- After opening: 3 to 5 days in the refrigerator in a sealed container.
- After cooking: 2 to 3 days in the fridge.
The printed “best by” date is simply the manufacturer’s estimate for peak quality. The broth remains safe to use well past that date, provided you store it correctly.
Many sources agree that unopened boxed beef broth lasts 1 to 2 years at a cool room temperature when the carton is sealed. For example:
- StillTasty.com says 1 year past the date on the package
- EatByDate.com states 1 to 2 years past the printed date
- The Kitchn recommends 1 to 2 years past the “best by” date
So while the package states a “Best by Jan 2020” date, you likely have until 2022 or even 2023 before it expires. Just be sure to store it properly (see tips below).
Proper Storage of Beef Broth Cartons
To get the full 1 to 2 years of shelf life from beef broth, proper storage is crucial. Here are some tips:
- Store unopened cartons of beef broth in a cool, dry pantry away from direct sunlight, moisture, and heat sources. Ideal temperature is below 75°F.
- Keep the carton upright and check periodically for any signs of leaks or damage. Don’t use if the packaging is compromised.
- Make sure the top is sealed. Once opened, transfer any unused broth to an airtight container in the fridge.
- Check the “best by” date and use older boxes first. Rotate your supply. Don’t overload your pantry with beef broth.
- If the beef broth ever smells unpleasant or looks discolored, err on the safe side and toss it out.
Follow these guidelines, and your beef broth should maintain optimal quality well past the 1-2 year mark if unopened.
What Happens After Opening Beef Broth
Once you open the carton or box, the shelf life is reduced to just 3 to 5 days in the refrigerator. The exposure to air and microbes shortens the freshness period.
Here are some tips for storing opened beef broth:
- Immediately transfer any unused beef broth to an airtight container or jar with a tight-fitting lid. Mason jars work well.
- Keep the container of beef broth in the fridge, not the pantry. Refrigeration is key for slowing bacteria growth.
- Use the opened beef broth within 5 days. Discard any leftovers after 1 week in the fridge.
- Don’t leave the carton or box out on the counter. Keep unused portions sealed up and chilled in the fridge.
Also, if you cook with the beef broth, use the leftovers within 2-3 days. Don’t let cooked broth sit in the fridge for a week.
Signs Beef Broth Has Spoiled
As you use up older boxes of beef broth, keep an eye out for these warning signs of spoilage:
- Off odors, sour smell, or very strong aroma
- Change in appearance – gray, dull, or darker color
- Separation and layering of liquid & solids
- Slime, stickiness, or texture changes
- Mold growth – discard immediately if you see this
If there are any such changes, don’t take risks – throw the beef broth away. It’s not worth getting sick over.
Tips for Buying & Using Beef Broth
When buying boxed beef broth, follow these tips:
- Check dates and select newest cartons in back of shelves
- Inspect packaging – shouldn’t be damaged, puffed out, or leaking
- Buy smaller boxes if you only use occasionally – 32 oz can be too big
- Look for low/reduced sodium if you want less salt
- Consider organic, non-GMO options if that’s important to you
And when cooking with beef broth:
- Give the carton a good shake before opening to recombine ingredients
- Look and smell for spoilage before using
- Measure it out into a liquid measuring cup rather than pouring from the carton
- Don’t leave the carton sitting out on the counter after opening
