Cooking With Frozen Seafood: Everything You Need To Know

Hello Seafodies,

We’re officially three months into the new year, which makes this the perfect pause for a little resolution check-in. How are those goals holding up? If “cook more at home” or “get better in the kitchen” made your list—and some version of this seems to be on a lot of people’s lists—this is actually the ideal time to make real progress. The weather’s still iffy, social calendars are typically spotty and most of us are still spending plenty of nights and weekends cooped up inside anyway. Why not use those moments to expand or refresh your culinary skills?

Here’s the thing, though—building cooking confidence doesn’t have to be a big undertaking with long trips to the grocery store to shop for fresh ingredients multiple times a week or stressing about perfectly lining up a trip to the fish counter with a complicated meal plan. One of the smartest culinary skills you can develop is knowing how to work with frozen seafood. It’s versatile, convenient, can stay fresh in your freezer for months and gives you the freedom to cook nutritious, protein-rich meals whenever your ever-changing schedule allows. 

So, without further interruption, welcome to our official Dish on Fish guide to choosing, thawing and cooking frozen seafood like a pro (including a few of our favorite recipes to practice your skills). For newbies and cooking connoisseurs alike, you’re in the right place to learn or refresh your kitchen expertise!

Let’s start by clearing up a common misconception—frozen seafood is nowhere near second-rate to fresh. Most frozen seafood is flash-frozen at the time of catch, which locks in all those nutrients, omega-3s and fresh-from-the-ocean flavor. Frozen seafood delivers the same protein, vitamins and health benefits as fresh and can expand your options when bargain shopping and being flexible with your meal plan. 

Choosing Quality Frozen Seafood

Not all frozen seafood is created equally, so knowing what to look for makes a real difference. Skip any packages that are open, torn or crushed along the edges. Avoid fish with visible frost or ice crystals—that usually means it’s been stored too long or has been thawed and refrozen, which seriously impacts both texture and taste. The seafood should feel rock-solid, not bendable. If the “frozen” fish has any give to it, keep looking. You also want to avoid any packages with white spots, dark patches or discoloration on the flesh. If you’re watching sodium or calories, steer clear of pre-breaded, fried or heavily sauced frozen seafood meals. Instead, buy plain frozen fish and bread it yourself, toss it in the air fryer or make your own marinade —allowing you to control exactly what goes into your meal.

Thawing Frozen Seafood the Right Way

The best way to thaw frozen seafood is overnight in the fridge. Cut a small hole in the vacuum-sealed packaging, place it in a bowl or large baggie and stick it in the coldest part of your fridge—usually toward the back, definitely not in the door where temperatures fluctuate. Let it thaw slowly overnight, then drain any liquid that’s collected, pat the fish dry with paper towels and use it within a day. Need dinner tonight and forgot to plan ahead? We’ve been there. Place the sealed frozen fish in a dish in the sink and run a steady stream of cold water—not warm, not hot, just cold—over it. The constant flow helps it thaw evenly. Check every ten minutes by pressing on the fish to see if it’s softening. Once thawed, usually within 30 minutes, remove from packaging, dry thoroughly with paper towels and cook as you normally would. One important rule: never refreeze raw seafood that’s already been thawed. The texture and flavor just won’t hold up. That said, if you’ve thawed seafood, cooked it and have leftovers, freezing the cooked fish is totally fine!

Cooking Seafood Straight from Frozen

Here’s where frozen seafood really steps up and where your cooking skills get a serious upgrade. Did you know you can cook many kinds of seafood directly from the freezer in tons of recipes? Drop frozen shrimp into a sauté pan or soup pot to give your favorite dish an instant protein boost. Brush frozen fillets with your favorite sauce before cooking and it freezes into a glaze that melts beautifully into the fish as it cooks. Pretty cool, right? Cooking from frozen also makes it nearly impossible to overcook your fish, though you’ll need to add some extra cooking time and should check that the internal temperature reaches 165°F to ensure it’s thoroughly cooked through. Stock your freezer with quality frozen fish and shellfish, master these basics by trying some of the recipes in our roundup below and you’ll always be prepared to put a great meal on the table.

Triple Seafood Boil

As far as recipes go, a boil is incredibly simple: Add thawed or frozen seafood and veggies to a pot of heady broth, then let ‘er steam (See! We said it was straightforward). Just one little reminder—if you bring fresh clams or mussels home, remove them from the netting and place in the fridge on a bowl of ice until cooking time. If using frozen, follow any directions on the packaging to prep them for the boil!
