How to Freeze Fish Without a Vacuum Sealer

Freezing fish preserves its freshness and flavor, allowing you to experience the flavors of the sea whenever you want. While vacuum sealers are popular for this reason, they are not available to everyone. Not to worry! This post looks at different ways to freeze fish without a vacuum sealer so your seafood stays fresh. Whether you’re an angler with a plentiful catch or a seafood fan looking to stock up, we’ve got you covered.

Freezing Fish Without a Vacuum Sealer

Here are various excellent methods for freezing fish without a vacuum sealer, each with its own set of benefits:

1. The Water Immersion Method

The water immersion method is quick and easy to freeze fish without a vacuum sealer. To begin, place the fish in a resealable plastic bag. Fill a container halfway with water and submerge the bag, making sure all of the air is squeezed out. Place the bag in the freezer and carefully seal it. The surrounding water pressure will protect the fish, preventing freezer burn and preserving its quality.

2. The Oil Coating Technique

Coating fish with oil before freezing helps to keep its moisture and flavor. Brush the fish fillets with a thin layer of cooking oil, such as olive or vegetable oil. Wrap each fillet in plastic wrap or wax paper, making sure no exposed parts exist. Place the wrapped fish in a freezer-safe container or bag and freeze it.

3. The Ice Glaze Method

The ice glazing method calls for partly freezing the fish before placing it in a resealable bag. Place the fish on a baking sheet in the freezer until the surface is somewhat hard. Then, place the partially frozen fish in a plastic bag and squeeze out as much air as possible before sealing. This method keeps the fish from sticking together and makes it easy to thaw individual sections as needed.

4. The Aluminum Foil Wrap

Without a vacuum sealer, aluminum foil works brilliantly for preserving fish. Wrap each fish fillet tightly in aluminum foil, ensuring it is completely covered and sealed. Before putting the foil packages in the freezer, label them. This procedure is especially effective for freezing delicate fish kinds in order to keep their shape during freezing and thawing.

5. The Saltwater Brine Solution

The saltwater brine solution is a fantastic alternative for fish with delicate tastes. Make a brine by dissolving salt in cold water, careful not to make it overly salty. Immerse the fish in the brine solution for 20-30 minutes, depending on the thickness of the fillet. Before freezing, pat the fish dry and place it in a freezer-safe container.

6. The Freezer Paper Wrap

Freezer paper acts as a barrier against freezer burn while preserving the fish’s freshness. Wrap each salmon fillet in freezer paper individually, sealing with tape if required. Label the packets and store them in a freezer bag or container for easy access.

7. The Modified Atmospheric Packaging (MAP)

Modifying the environment inside a packaging container to improve the shelf life of fish is known as modified atmospheric packaging (MAP). While it is often utilized in commercial settings, a reduced version can be used at home. Make a small opening in a standard freezer bag before sealing it. Gently pump air into the bag to slightly inflate it, then rapidly seal it. The carbon dioxide you breathe will alter the atmosphere, which will aid in the preservation of the fish.

8. The Citrus Juice Marinade

Marinating fish in citrus juice improves its flavor and helps it last longer when frozen. Make a marinade with lemon, lime, orange juice, and your favorite herbs and spices. Allow the fish to rest in the marinade for 15-20 minutes before draining and freezing.

9. The Butter Wrap

Wrapping fish in butter before freezing can provide a layer of protection against freezer burn. Coat each fish fillet gently with softened butter, covering all exposed regions. Wrap the fillets individually in plastic wrap or wax paper and place them in a freezer-safe container or bag.

10. The Vegetable Bed Method

Make a bed of sliced veggies like onions, carrots, and celery in a freezer-safe container. Cover the fish fillets with another layer of veggies after placing them on top of the vegetable bed. This approach insulates the fish and keeps it from adhering to the container.

11. The Ice Water Bath

Consider giving the fish an ice water bath before freezing it. This procedure aids in the removal of excess blood and contaminants, retaining the taste and texture of the fish. Immerse the fish in a bowl of ice water for a few minutes before patting it dry and freezing it according to your preference.

12. The Silicone Freezer Bag

Investing in silicone freezer bags can be an eco-friendly and reusable alternative to vacuum-sealing seafood. These bags are airtight, which prevents freezer burn and keeps your fish fresh. Before sealing, eliminate as much air as possible.

13. The Dry Ice Method

Dry ice is an excellent approach for long-term freezing. Place the fish in a container with dry ice, making sure it’s well covered to avoid direct contact. Keep the container in the freezer; the dry ice will keep the fish at an extremely cold temperature, extending its shelf life.

14. The Alcohol Solution

Using alcohol, such as vodka, can help prevent ice crystals from forming on the surface of the fish during freezing. Make a solution of water and alcohol, then soak the fish in it before wrapping and freezing.

15. The Sealing with Water Technique

If you don’t have a vacuum sealer, you can achieve the same effect by removing air from the packaging using water. Place the fish in a resealable bag and gradually lower it into a bowl of water, letting the water push the air out. Once the air has been evacuated, securely seal the bag.

16. The Rapid Freezing Method

Rapid freezing preserves the texture of the fish by preventing big ice crystals from forming. Place the fish on a baking sheet in the coldest section of your freezer for a few hours or until completely frozen. Transfer the frozen fish to a storage container or bag.

17. The Portioning Technique

Divide your fish into discrete parts before freezing to make thawing only what you need easy. To keep the food fresh, place each serving in a separate freezer-safe bag or container that is well-sealed.

18. The Vacuum Sealer Alternative

If you don’t have a vacuum sealer, consider using the straw suction approach. Put the fish in a resealable bag with a straw in one corner. Close the bag almost entirely, leaving a small opening for the straw. Suck out the air with the straw before sealing the bag the rest of the way.

19. The Use of Freezer Tape

You can use freezer tape to secure products when you don’t have a vacuum sealer. After wrapping the fish in plastic wrap or wax paper, seal the package tightly with freezer tape.

20. The Buttermilk Bath

Try the buttermilk bath approach for a distinctive spin. Soak the fish for about 30 minutes in buttermilk, then remove and pat dry before freezing. The buttermilk offers a sour flavor while aiding in the fish’s preservation.

21. The Envelope Fold Technique

The envelope fold is a quick and easy way to produce an airtight seal without a vacuum sealer. Wrap the fish in plastic wrap before folding the edges over the fillet to form an envelope-like packet. To establish a secure seal, press down on the folds.

22. The Freeze and Zip Method

For little fillets, you can use frozen zipper bags and the water displacement method. Put the fish in a bag and close it almost completely, leaving a small gap. Immerse the bag in water, allowing the water to displace the air, and then thoroughly seal the bag.

23. The Use of Heavy-Duty Aluminum Foil

When it comes to larger fish or whole fish, heavy-duty aluminum foil is your best friend. Wrap the fish in numerous layers of foil to keep it safe while freezing.

24. The Garlic and Herb Rub

Rub the fish with smashed garlic, herbs, and olive oil before freezing to impart delicious flavors and keep the fish fresh.

25. The Citric Acid Solution

Make a solution with water, citric acid, or lemon juice, then briefly immerse the fish in it. To keep the flavor of the fish, pat it dry before freezing it.


Freezing fish without a vacuum sealer is not only doable but also simple if the proper techniques are used. Whether you choose the water immersion method, the oil coating method, or any other way we’ve mentioned, your fish will remain fresh and tasty until you’re ready to eat it. Experiment with these methods to find the one that works best for you, and you’ll be able to enjoy the flavor of the sea whenever you want.
