Generally speaking, thawing frozen tuna for sushi in the refrigerator works nicely. Just give it a quick rinse in cold water and wrap it in a fresh cloth that has been saturated with saltwater. For 8 to 12 hours, place the tuna in a bowl and refrigerate it.
Given that the frozen tuna would defrost at a secure and stable temperature, it is a good method. The drawback is that it takes a while.
The steps are as follows:
- Frozen tuna should be taken out of its package and put in a bowl that has been lined with paper towels.
- Make sure you use paper towels or plastic wrap to cover the bowl.
- To prevent cross-contamination, place the bowl of tuna alone on the lowest shelf of the fridge.
- Allow 8 to 12 hours for the tuna to defrost. I prefer overnight. If the paper towels get wet, you might need to replace them.
- Use paper towels to pat it dry after it has defrosted.
DECORATING “SUPER FROZEN” TUNA
You MUST thaw the super-frozen items within 24 hours after receiving them (if you are not having on the day of received, you can keep them in the regular freezer for 3-4 days on vacuumed-packed condition).
Any complaints or requests for returns or refunds resulting from deterioration, staining, or other issues as a result of disregarding our defrosting recommendations are not within our control.
O2 YELLOWFIN TUNA – CORRECT THAWING GUIDELINES:
- Place the tuna in a bowl while it is still in its vacuum bag, and then submerge the bowl in warm running water (80 degrees Fahrenheit) for 10 minutes in total. Please avoid letting the tuna come in contact with water directly. Please refrain from over-defrosting under running water.
- Paper towels should be used to line a glass or stainless steel container (to catch excess moisture).
- As soon as the tuna surface begins to become red, take the bowl out of the running water.
- To remove the tuna, open the pouch. With a piece of paper towel, dry the tuna’s surface of any extra moisture.
- To keep the tuna from drying out, put it in the prepared container and cover it with some plastic wrap.
- Defrost in the fridge for another 12 hours or more.
How to Defrost Fish for Sushi
If you’re not in a rush, placing the fish in the refrigerator overnight at 35 degrees is the easiest way to safely thaw it. As a result, the texture of the fish can be preserved while it gradually defrosts.
In addition, confirm that the fish you purchase was frozen quickly rather than slowly. Which is evident from the thickness of the fish’s layer of frost and the way the container is tightly closed.
Second, put the fish in a ziplock bag to seal inside if it is not already in a bag that is well shut. Then soak the bagged fish for an hour in a tub of lukewarm water (60 degrees Fahrenheit).
Finally, to remove the moisture from the fish, use some handy paper towels in your kitchen.

Can you make sushi with frozen tuna?
All tuna (and other seafood) that is excellent for sushi will often have been frozen in advance. However, it will be marked as “sushi-grade” or “sashimi-grade” if it is actually safe for consumption uncooked. Therefore, avoid using any frozen tuna.
Tuna is flash-frozen at the necessary temperature to eliminate viruses as soon as they are taken at sea, after being slaughtered and cleaned.
Why? When fish are caught, they frequently have parasites inside of them like the majority of other animal proteins. These are parasites and bacteria that are dangerous to us.
Therefore, it seems sense that the FDA has rules in place requiring that fish, including tuna, be frozen at a specific temperature as soon as they are caught.
At reality, almost all tuna—even that served in upscale sushi restaurants—has been frozen before being prepared.
Some sushi experts think that freezing tuna helps preserve the flavor in addition to killing germs. So feel free to make sushi with your frozen tuna.
This brings up an intriguing query: Is salmon from the grocery store raw to eat?
I discuss topics like whether you can eat raw fish at the grocery store and what happens if you eat raw salmon in a recent piece I authored.
I demonstrated which salmon, from Costco or Walmart, was safe to eat uncooked. But I also disclosed if salmon can be frozen to eradicate parasites.
Is canned tuna okay for sushi?
I enjoy eating seared ahi tuna. But sashimi is also fantastic! And even while I am aware that the majority of supermarkets sell tuna steaks, I was curious if you could eat raw tuna steak from the supermarket.
Here is what I found:
Only tuna steaks marked as sushi- or sashimi-grade from the grocery store should be eaten uncooked. The best fish for sushi or sashimi was caught, cleaned, and immediately frozen while still on the boat, though this is still no guarantee against parasites.
Don’t consume something uncooked if it isn’t stated on the label. There is a difference in quality. I’ll explain why shortly.
Salmon and tuna from Bessie are all of sashimi quality! Which sushi variety is your favorite?
How can frozen tuna be quickly thawed?
In the refrigerator, thaw. Remove from plastic wrapping when defrosting. Below 38°F, cover and refrigerate. Consume within one to two days of thawing.
Unpack the necessary quantity of fish fillets and put them in a plastic bag that can be sealed. The bag should be deflated as much as possible before being submerged in cold water for about 30 minutes.
Ahi tuna steaks that are medium rare:
Pre-heat the grill. Melted butter or olive oil should be used to brush tuna steaks. Add flavor as desired. Steaks should be cooked for 60 to 90 seconds on each side of the grill. Larger quantities might require a little more time. Do not overcook.
Pan Saute: Heat 1 teaspoon of olive oil per serving over high heat in a saute pan. Add flavor as desired. Place tuna steaks in the pan and sear for 60–90 seconds on each side. Larger quantities might require a little more time.
Medium-sized steaks of tuna:
Grill: Fire up the grill or the broiler. Melted butter or olive oil should be used to brush tuna steaks. Add flavor as desired. Steaks should be cooked for four to five minutes on each side on the grill or broiler. Larger quantities might require a little more time. Do not overcook.
Oven: Heat to 400 degrees Fahrenheit. Lightly brush melted butter or olive oil on steaks. Add flavor as desired. Tuna steaks should be placed on a baking sheet on the middle oven rack. Bake for 10 to 12 minutes, or until completely opaque. Do not overcook.
Pan Saute: Heat 1 teaspoon of olive oil per serving over medium heat in a saute pan. Add flavor as desired. Steaks should be cooked in a pan for 4-5 minutes. After flipping, cook for an additional 3–4 minutes.
Can sushi be made with frozen fish?
The good news is that fish that has been frozen can still taste excellent if it is of high quality. Using frozen fish for preparing your own sushi has financial advantages as well. Frozen fish is far more affordable and can be kept on hand for whenever you have a taste for sushi or sashimi.
Can you eat raw tuna from frozen?
The easiest approach to get rid of parasites and reduce your chance of contracting a foodborne illness is to cook tuna. However, it is still safe to consume raw tuna.
To get rid of parasites, the Food and Drug Administration (FDA) suggests freezing raw tuna in one of the following ways (20):
- 7 days of freezing at -4degF (-20degC) or below
- Frozen at -31degF (-35degC) or lower until solid, then kept at that temperature for 15 hours.
- storage for 24 hours at -4degF (-20degC) or lower and freezing at -31degF (-35degC) or lower until solid
The majority of parasites will probably be killed by using this procedure, but there is a slight possibility that not all parasites will be removed.
The majority of eateries that offer sushi or other types of raw tuna adhere to the FDA’s freezing guidelines.
Ask for further information and only consume raw tuna from reputed establishments if you have any concerns about how it was prepared.
Look for a trustworthy fishmonger who is informed about the origin of their fish and how it is handled if you intend to prepare a raw tuna dish at home.
If raw tuna has been frozen to kill parasites in compliance with FDA requirements, it is typically safe to consume.
Is the sushi at Costco of a high standard?
Nothing compares to preparing sushi at home. And one of the best fish to utilize for sushi is ahi tuna. Although I am aware that Costco offers excellent prices on ahi tuna, I was unsure if the fish was sushi grade.
One of the two fish varieties commonly referred to as ahi tuna is yellowfin tuna, which is available at Costco in sashimi-grade, super-frozen form. Bigeye tuna is the alternate variety, which Costco does not frequently carry.
Additionally, they provide wagyu sashimi-grade yellowtail, popularly known as hamachi. This is also ideal for sushi. However, even fish marketed for sushi is not completely risk-free.
However, yellowtail and yellowfin tuna should not be confused. Yellowtail or hamachi is not a species of tuna.
So, that’s just a brief response and doesn’t cover everything. After all, most supermarkets don’t mark fish as “sushi-grade” because they don’t want to be held responsible if a customer consumes it, becomes ill, and blames the tuna. And does the term “sushi-grade” or “sashimi-grade” even fall under any Federal regulations?
How do you tell if tuna is fit for sushi?
The main distinction between our sushi and that sold in stores is that some fish isn’t truly sushi grade. Before buying raw fish, take note of the following:
- The quality and freshness of seafood can be judged by its appearance and texture. The color of the tuna will be a key factor in deciding whether it is actually sushi grade. Avoid tuna that has a crimson color that is plastic-like, bright, and nearly transparent. Anything that appears overly colorful has likely undergone chemical treatment to make it appear more fresh. Ours feels and appears genuine.
Advice: Once tuna is placed in the freezer, it naturally begins to brown. Tuna has most likely been chemically treated if it can be frozen and retains its color. It’s crucial to remember that while the color is preserved, the freshness is not. Tuna can occasionally be frozen for up to two years!
