Homemade fish stock is a wonderful base for seafood soups, risottos, and sauces. The concentrated fish flavor adds richness and depth to any dish But like any perishable food, proper storage is key to enjoying fish stock safely. Follow these guidelines on fridge and freezer times to get the longest lasting homemade fish stock
Overview of Fish Stock
Fish stock also called fish broth, is made by simmering fish bones heads, and fins in water with aromatics like vegetables, herbs, and spices. This extracts the fish flavors and collagen into the liquid. The strained stock provides a burst of seafood essence.
Fish stocks have a shorter shelf life than meat broths due to higher perishability. But with attentive storage methods, you can still keep homemade fish stock for moderate periods.
Refrigerator Storage Time
Prepared fish stock will maintain best quality for:
- 3 to 4 days in the refrigerator
The key is cooling the stock quickly after cooking and keeping it chilled below 40°F. Transfer hot stock to a clean container and place in an ice bath to rapidly cool before refrigerating
Ensure the container is airtight. Use glass or plastic – reactive metals like copper and aluminum can discolor fish stock.
Check for spoilage signs like off-odors, cloudiness, or sliminess before use. Discard if any develop.
Freezer Storage Time
For longer storage, homemade fish stock freezers well for:
- 4 to 6 months in the freezer
Use freezer-safe airtight containers or resealable plastic bags. Exclude as much air as possible to prevent freezer burn.
Smaller portion sizes freeze faster and thaw more quickly when needed. Consider freezing stock in ice cube trays then transferring to bags.
Label containers with the date and contents. Place in coldest freezer zone, at 0°F or below.
Thawing and Reusing Frozen Stock
To use frozen fish stock:
-
Thaw overnight in the refrigerator for best quality.
-
Microwaved or cold water thawed stock should be used immediately.
-
Reheat gently on the stovetop or in the microwave.
-
Use within 3 to 4 days for thawed homemade stock.
Avoid repeated freeze-thaw cycles. The texture and flavor will degrade over time.
Food Safety Tips
Follow proper food handling practices when making and storing fish stock:
-
Refrigerate within 2 hours of cooking. Do not leave stock at room temperature.
-
Simmer stock gently – boiling can make it cloudy. Skim off any scum during cooking.
-
Use the freshest fish possible and clean bones thoroughly.
-
Strain stock through cheesecloth to remove solids and impurities.
-
Cool in an ice bath before refrigerating or freezing.
-
Freeze in small batches for easier thawing and use.
-
Do not use stock that smells unpleasant or looks spoiled.
Storing Commercial Fish Stock
While homemade fish stock has a shorter shelf life, store-bought varieties last longer due to sterilization methods and preservatives. Refer to package dates, but generally:
-
Commercial stock lasts about 1 week past the sell-by date if refrigerated.
-
Unopened, shelf-stable boxes can be stored up to 2 years at room temperature.
-
Opened boxes of fish stock granules keep for about 8 months refrigerated.
Check for changes in appearance, aroma or texture over time. Discard if any staleness develops.
Signs of Spoiled Fish Stock
Watch for these indications that fish stock has spoiled:
-
Sliminess, gelling, or mucus-like consistency
-
Cloudy appearance instead of clear amber liquid
-
Sour, stale, rancid or rotten smell
-
Mold growth inside container
-
Yeasty odors from fermentation
When in doubt, remember the old adage “When fish smells like fish, throw it out and fish some more”. Off-smells indicate contaminated stock.
Key Takeaways
Storing homemade fish stock properly ensures you can safely enjoy its flavor enhancing benefits. Follow these storage guidelines:
-
Refrigerate for 3 to 4 days or freeze for 4 to 6 months.
-
Cool rapidly after cooking and seal in airtight containers.
-
Freeze in small batches for easier use.
-
Thaw frozen stock slowly in the refrigerator.
-
Discard if any spoilage signs or smells develop.
With the right storage methods, your homemade fish stock will deliver bold seafood essence to recipes for months to come.
Tip for Making Fish Stock Recipe
When making fish stock, bones from mild, lean white fish like halibut, cod, or flounder work best. As a general rule, you should stay away from oily fish like salmon, trout, mackerel, and others like them. Their strong flavor will probably swamp your finished dish. (Unless you’re making something specific, like salmon broth, the stock made from salmon bones will have an unbelievably deep, rich salmon flavor. ).

The Spruce Eats / Victoria Heydt - Place two to three sprigs of fresh thyme, two to three whole peppercorns, one clove, three to four sprigs of fresh parsley, and one large bay leaf inside a piece of cheesecloth. This will make a sachet. Set aside. The Spruce Eats / Victoria Heydt .
- Over medium heat, melt 2 tablespoons of unsalted butter in a stock pot or soup pot with a heavy bottom. The Spruce Eats / Victoria Heydt .
- Lower the heat and add one stalk of celery, one medium-sized carrot, and one medium-sized onion. Chop the vegetables up very small and add them to the pan. Warm the mixture very slowly, with the lid on, for about five minutes, or until the onion is soft and slightly see-through but not brown. The Spruce Eats / Victoria Heydt .
- Add 4 pounds of fish bones and heads (without the gills), cover the mixture with parchment paper, and put the lid back on the pot. Let the bones warm slowly until they become slightly opaque. The Spruce Eats / Victoria Heydt .
- Take the paper and lid off the pot. Add 1 cup of dry white wine and raise the heat until the stock begins to melt. The Spruce Eats / Victoria Heydt .
- Set the pot on low heat and add the sachet and 1 gallon of cold water. Cook for 30 to 45 minutes. The Spruce Eats / Victoria Heydt .
- Strain (you can take out the fish bones first if that helps), let it cool, and then put it in the fridge. The Spruce Eats / Victoria Heydt .
