Frozen salmon is a kitchen staple for many home cooks. It’s affordable, nutritious, and convenient to keep on hand. But what happens when you forget to take it out of the freezer ahead of time? Don’t worry! This comprehensive guide will show you exactly how to defrost salmon quickly without compromising quality or safety.
Why Proper Defrosting Matters
Before we dive into the methods, let’s understand why proper thawing is important. Salmon is a delicate fish that can lose its texture and flavor if defrosted incorrectly. More importantly, improper thawing can create food safety issues by allowing harmful bacteria to grow.
1: How to Defrost Salmon Quickly in Water (The Fastest Safe Method)
The cold water method is the best answer when you need to know how to defrost salmon quickly and safely. This technique is fast, effective, and keeps your fish at a safe temperature throughout the process.
Step-by-Step Instructions:
- Keep your salmon in its original packaging or place it in a sealed plastic bag to prevent water from getting in
- Fill a large bowl with cold tap water
- Submerge the salmon completely in the cold water
- Change the water every 10-15 minutes to keep it cold
- Your salmon should be ready in 30-60 minutes, depending on thickness
This method for how to defrost salmon quickly in water works because water conducts temperature much better than air. The cold temperature keeps bacteria at bay while the water efficiently transfers heat to thaw the fish.
Pro Tip: Never use warm or hot water, even though it might seem faster. We’ll explain why later in this article.
2: How to Defrost Salmon in Microwave
When you’re really pressed for time, the microwave can be your friend. Here’s how to defrost salmon in microwave properly:
Microwave Defrosting Steps:
- Remove all packaging and place salmon on a microwave-safe plate
- Use the defrost setting on your microwave (usually 30% power)
- Defrost in 30-second intervals
- Flip the salmon after each interval
- Check for ice crystals between each cycle
How long to defrost salmon in microwave? Generally, it takes 3-5 minutes for a standard fillet, but timing varies based on thickness and your microwave’s power. The key is to check frequently to avoid cooking the edges.
Important Warning: Cook the salmon immediately after microwave defrosting. The microwave can create warm spots that encourage bacterial growth, so don’t let it sit after thawing.
3: How to Defrost Salmon in Fridge (The Safest Method)
While not the quickest option, learning how to defrost salmon in fridge is the gold standard for food safety. This method requires planning ahead but delivers the best texture and flavor.
Refrigerator Thawing Process:
- Place frozen salmon on a plate to catch any drips
- Put it on the bottom shelf of your refrigerator
- Allow 12-24 hours for complete thawing
- Use within 1-2 days after defrosting
This slow, steady approach keeps your salmon in the safe temperature zone throughout the entire process. While you can’t use this method when you need to defrost salmon quickly, it’s perfect for meal planning.
4: How to Defrost Salmon Air Fryer Method
Modern air fryers have made defrosting even easier. Here’s how to defrost salmon air fryer style:
Air Fryer Defrosting:
- Place frozen salmon in the air fryer basket
- Set temperature to the lowest setting (usually around 100-120°F)
- Run for 5-minute intervals
- Check and flip the salmon between intervals
- Total time: 10-15 minutes
Some people prefer to skip defrosting entirely and cook frozen salmon directly in the air fryer. This brings us to an important question many people ask.
Can I Cook Salmon from Frozen?
Yes! You absolutely can cook salmon from frozen. In fact, many chefs recommend this method. When cooking frozen salmon:
- Add 50% more cooking time to your recipe
- The internal temperature should reach 145°F

Expert Tips and Tricks for Defrosting Salmon
Now that you know how to defrost salmon quickly, here are some insider tips to make the process even better:
Quick Thawing Tips:
Use a Metal Bowl for Water Thawing: Metal conducts temperature faster than plastic or ceramic. Place your sealed salmon in a metal bowl with cold water to speed up the process by 20-30%.
Split Thick Fillets: If you have a particularly thick piece of salmon, consider cutting it into smaller portions before freezing. This dramatically reduces thawing time.
The Aluminum Foil Trick: Place your sealed frozen salmon between two sheets of aluminum foil on your countertop. The metal helps conduct ambient temperature more efficiently. Combined with cold water changes, this can cut defrosting time in half.
Create a Water Current: When using the cold water method for how to defrost salmon quickly in water, place the bowl under a slowly dripping faucet. The constant cold water movement speeds up thawing.
Vacuum Seal for Faster Freezing and Thawing: Vacuum-sealed salmon freezes faster and more evenly, which means it also thaws more uniformly when you need it.
Storage and Prep Tips:
Freeze Salmon with Marinade: Place salmon in a freezer bag with your favorite marinade before freezing. As it thaws, it marinates simultaneously, saving you time.
Flash Freeze Individually: Freeze individual portions on a baking sheet first, then transfer to a bag. This prevents them from sticking together and lets you thaw exactly what you need.
Label with Weight and Date: Write the weight and freeze date on your packaging. This helps you estimate thawing time more accurately.
The Paper Towel Method: When defrosting in the fridge, place paper towels under and over the salmon. They absorb excess moisture and help prevent that slimy texture.
Texture-Saving Tips:
Don’t Rush Room Temperature Thawing: Even though we discussed how long to defrost salmon at room temperature, it’s better to avoid this entirely. The texture suffers significantly compared to other methods.
Pat Completely Dry: After thawing, pat your salmon completely dry with paper towels. This is crucial for getting crispy skin when pan-searing.
Brine After Thawing: A quick 10-minute brine in saltwater (1/4 cup salt per quart of water) can restore moisture lost during freezing and add flavor.
Check for Ice Crystals: Before cooking, make sure all ice crystals are gone, especially in thicker parts. Ice crystals will release water during cooking and make your salmon soggy.
Time-Saving Hacks:
Portion Before Freezing: Freeze salmon in meal-sized portions. Single servings thaw in 15-20 minutes using the cold water method.
Use a Sous Vide: If you have a sous vide machine, set it to 40°F and submerge your sealed salmon for gentle, even thawing in about 30 minutes.
The Saltwater Speed Boost: Adding 1-2 tablespoons of salt to your cold water bath can lower the freezing point slightly and speed up thawing. Just rinse the salmon well afterward.
Prep During Thawing: Use the thawing time to prep your sides, make sauces, or set up your cooking station. Multitasking makes the wait time feel shorter.
