We all know how healthy seafood is to eat; however, to enjoy it fully, we recommend the following suggestions to Make It Easy!

Fish Fillets

- Sear Medium to High

- 3 to 5 minutes

- Max Finish Temp 145°F

Fish Portions (6-8oz)

- Broil or Bake (350°F Pre-Heated)

- Bake Time 12-20 mins (Thickness)

- Max Finish Temp 145°F

- Seafood Should be Flaky


- Sear Medium to High

- 3 to 5 minutes

- Finish Temp 130-140°F



- Sear Med. High to High

- 45-90 Seconds per side

- Finish Temp 120°F



- Pre-Heat Oven to 350°F

- Baked for 15 minutes

- Use a meat thermometer (140-145°)

- Brush with butter frequently


- Boil Salted Water

- Reduce to Low Bubbling

- 3 to 5 Minutes (3-6oz Tail)

- Add 1 minute for each additional ounce

- Cool immediately in ice water

Please Note: The above guidelines are suggestions only. The average time depends on the size/amount of seafood portions. Stoves and pans also vary in performance, so check color and texture regularly to achieve perfectly cooked seafood. Please use a meat thermometer for accuracy.

Thawing frozen seafood properly is significant not only to ensure the quality of the seafood but also to prevent health risks. For example, all of our seafood has a protective glaze of water to prevent freezer burn-in to ensure quality. Once thawed, gently pat away any excess moisture from the glazing as soon as possible.

We recommend that you follow the USDA’s instructions on safe food handling, which can be found here. We also recommend that all cooking instructions are followed and that you use a food thermometer to ensure that all seafood and other applicable items are cooked to the USDA’s recommended internal temperatures, which can be found here.

Here are a few simple ways how to defrost:

The Refrigerator Method

It might be the longest, but thawing seafood in the refrigerator is undoubtedly the safest way to thaw any protein such as seafood. It also protects the quality of the seafood, providing the best quality-control method. For example, for our Individual Frozen Portions (IFP) or Individually Quick Frozen (IQF) bags like our shrimp and scallops, it can take up to 12- 24 hours to thaw. Please remove from the original package, plate, and cover, or at a minimum, puncture the plastic packaging. Once melted, seafood lasts up to three days in the original packaging. Do not refreeze after thawing.

The Water Method

Here’s how it works:

IFP Portions: Place the seafood in a bowl of cold water (not warm or hot as that starts the cooking process) in the kitchen sink. Change the water now and then or place a constant drip/spray of water to control the temperature. Check the seafood after one hour – it should be fully thawed by then. Cook immediately after thawing.

IQF bags:

Place the desired quantity of seafood (scallops/shrimp) that you will use into another resealable bag.Replace unused IQF seafood immediately back into the freezer.Submerge the sealed bag in a bowl of cold tap water.Let the bag sit in the water until it’s completely thawed, changing the water every 30 minutes, if necessary.

We don’t recommend running under cold water outside of the bag. Cook immediately after thawing.

The Microwave Method

Not always the favorite way, but it’s fast, and the microwave method is undoubtedly the quickest of the three. Still, it’s the least preferred method to preserve the seafood’s quality. But if you forgot to take it out of the freezer and are in a hurry, here’s what you do: make sure you puncture the plastic before placing it in the microwave. Use the “Defrost” function and set the time according to weight. Cook immediately after thawing.

The Best You Can Buy

Boy, am I glad I found KnowSeafood! I live in the mountains, an hour away from the closest grocery store, so I do shop online when I can. I am so happy to be able to buy high quality seafood, well packaged and at a reasonable price. I love when I happen to have enough freezer space to take advantage of the flash sales. Everything I have tried has been fantastic! I think my favorite "everyday" meal is the Aurora Salmon, with scallops and lobster tails being special treats (just because I deserve it). But really everything is so good. I appreciate that no membership is required but I will continue buying regularly and singing the praises of KnowSeafood to anyone smart enough to listen.

Keto box review

The fish was still very frozen when it arrived in very nice packaging. All the fish has tasted great so far. Really loved the scallops. We have tried other boxes and my all time fav is black cod.

Knowseafood is a game changer! Love!

I am so thankful to have found a safe and sustainable source of absolutely delicious seafood. Ordering was easy, service was excellent, the recipes and stories behind the catch are a huge bonus and I think also show how much the people behind this fantastic source of fish really care. Economical. Perfect portions. Beautiful fish. I’ve loved the Yellowfin Tuna, Rainbow Trout, Mahi Mahi. I am not a cook and have very little interest in cooking but having the trust in the fish safety and the recipes made it easy to make amazing meals! Tonight - Sea Scallops. Thank you, Knowseafood - am a customer for life.

So fresh!

I love, love, love your seafood. I can count on everything being fresh caught and I love the portion control. My order arrived still frozen, not easy to do in this heat. Your Aurora salmon is divine and, though I didn't get it in this delivery, the sablefish cooks up SO deliciously.

So glad I ordered!


What’s in the Box?

Each box has been personally curated by our crew, along with some help from our KnowBuddies! Here is what this box has to offer!

Rainbow Trout Fillets

Our PezCo Rainbow Trout fillets are humanely raised in natural spring waters from the Andes Mountains. Our Rainbow Trout fillets are fed a plant-based diet free of antibiotics or additives. Surprisingly flavorful and very easy to prepare and cook, you will understand why PezCo Rainbow Trout Fillets are frequently featured on menus from coast to coast by the country's top chefs. A versatile delicacy, our Rainbow Trout Fillets can be easily prepared for various dishes! 

Yellowfin Tuna Steaks
Our KS Signature Yellowfin Tuna are pole caught and landed from the dayboats at the dock, packed in ice, then immediately brought to the processing facility. The next step is to test for purity and safety as a random selection of fish is tested for mercury content, and any excess oxygen that may discolor the meat is removed. The tuna is then cut into loins, delicately hand-cut portioned into skinless, center-cut steaks, then packaged and blast frozen to ensure the quality and great taste. You will love these mild, tasty, firm KS Signature Yellowfin Tuna steaks a number of ways by either searing, baking, or grilling.
New England Wild Scallops

There are 10-20 wild sea scallops per pound, each scallop hand-shucked and hand-selected for quality and sizing. When you buy sea scallops from KnowSeafood they are never processed with any additives and preservatives; you will see a difference when cooking and eating them.

Buying sea scallops from KnowSeafood guarantees they’re deliciously meaty and sweet. These wild caught sea scallops are loaded with healthy Omega-3 fatty acids and vitamin B-12. The perfect size for baking and sautéing, Wild Caught Sea Scallops will become a go-to favorite for you to serve to family and friends.

Important! When you thaw our Wild Sea Scallops, please remove them from the bag. Thaw in a strainer, or on a plate with paper towels to absorb the glaze. Pat dry before cooking!

Wild Caught Mahi Mahi

Oceano Mahi-Mahi is a highly versatile fish that home cooks and chefs alike can use to make delicious, effortless meals. Broiled, grilled, pan-fried, skewered, steamed, or cut into strips and battered, our Mahi-Mahi is mild and has a sweet flesh that looks somewhat pink but turns white as it cooks. It’s very delicate, moist, and flavorful. A super healthy fish, check out our Mahi Mahi in our health-focused boxes.
