How to Cook Frozen Scallops for a Golden Sear

Frozen scallops can sear every bit as well as fresh ones, and most “fresh” scallops at the counter were previously frozen anyway. The trick to how to cook frozen scallops is almost entirely about water: thaw them first, dry them hard, and sear them in a very hot pan.

Skip the thaw and the surface ice floods the pan, so you get a gray, rubbery ring instead of a golden crust. This guide walks through thawing, drying, the sear itself, when frozen-to-pan is actually fine, and a simple recipe to put it all together.

TL;DR

• Thaw frozen scallops first: overnight in the fridge, or a sealed bag in cold water for 20 to 30 minutes.
• Pat them very dry, because a wet surface steams instead of searing.
• Sear in a hot pan 2 to 3 minutes a side, then baste to about 145°F.
• Never thaw on the counter, in warm water, or in the microwave.
• Buy dry-packed scallops (no STP) in a large size for the best crust.

Should you thaw frozen scallops first?

Almost always, yes. Good scallops are frozen fast at their peak, so frozen is not a downgrade, but a frozen scallop is full of ice that melts the moment it warms, and that water wrecks a sear. Drop frozen scallops into a hot pan and the surface ice turns to steam, the pan temperature crashes, and they poach in their own water instead of browning. You end up with a gray, rubbery ring and no crust.

There is a cooking-evenness angle too. A frozen center takes so long to warm that the outside overcooks in the 2 to 3 minutes before the middle thaws. Thaw fully and you get even cooking and a clean, hot pan.

How do you thaw frozen scallops?

Refrigerator thawing gives the best texture because it happens slowly and evenly. Spread the scallops in a single layer in a shallow dish, cover them, and give a pound of U10s about 12 hours, or a smaller 20/30 grade about 8. Overnight covers either one. Cold water is the fast lane: seal the scallops in a zip-top bag with the air pressed out, submerge it in a bowl of cold tap water, and count on 20 to 30 minutes for a pound, swapping in fresh cold water partway through if the bowl goes lukewarm.

Three methods deserve to be skipped. The counter parks the outside of each scallop in the 40 to 140°F range where bacteria multiply, the microwave cooks the edges to rubber before the centers give up their ice, and warm water manages both problems at once. USDA guidance backs the fridge and cold-water methods only. One extra step pays off: after either thaw, set the scallops on a rack over a plate and leave them uncovered in the fridge for 10 to 15 minutes, since moving air pulls surface moisture off better than paper towels alone.

What is the ice glaze, and why the puddle?

Most frozen scallops wear a thin coat of ice called a glaze. Right after freezing, they are dipped or sprayed with water, and that shell of ice seals the surface off from the air that causes freezer burn. It is a preservation step, not a trick, and a good glaze is why a scallop can sit frozen for months and still taste clean. The catch is weight: glaze adds a few percent to what is in the bag, so look for a net weight or a note that the weight was taken after glazing. Glaze also explains the puddle. As the scallops thaw, that ice melts and pools in the bag, and people read it as the scallops falling apart. Drain it and pat the scallops dry, because that liquid is glaze water, not scallop juice.

When is cooking from frozen actually fine?

The rule against cooking from frozen is really a rule about searing, where a dry surface is the whole game. In wet cooking the ice is beside the point, because the scallop was going to sit in liquid anyway. Drop frozen scallops straight into a simmering chowder, a coconut curry, or a tomato sauce and give them 5 to 7 minutes, until they are just opaque through the middle. A butter or oil poach held at 160 to 180°F works the same way and takes 2 to 3 minutes longer than with thawed scallops. Add a little extra seasoning, since the melting glaze thins the liquid slightly.

What will not work is broiling, grilling, or pan searing from frozen. There is no version of those where you get color. If dinner is 25 minutes out and the scallops are rock solid, either run a cold-water thaw or change the plan to something with a sauce.

How can you judge frozen scallops before cooking?

Open the bag and look before you commit. Good frozen scallops are ivory to pale pink or light tan, loose from each other, and covered in a smooth even glaze. Individually quick frozen pieces, labeled IQF, should rattle around in the bag instead of clinging together.

The bad signs are just as easy to read. Scallops frozen into one solid clump usually thawed and refroze in shipping, and heavy frost with chalky white patches is freezer burn. Stark bright-white scallops sitting in a milky slurry are typically wet-packed with sodium tripolyphosphate, and they will steam no matter how carefully you thaw them. Then smell them once thawed: fresh scallops smell faintly sweet and slightly of the ocean, while anything sour, sharp, or ammoniated is past saving. For the count grades and what they mean, see our scallop sizes explained guide.

How do you sear thawed scallops?

Dry them like you mean it first. Thawed scallops hold surface water, so lay them on paper towels, press gently with another towel on top, let them sit 10 minutes, and pat once more right before cooking. Season with salt only at the last second. If they still feel damp, they are not ready: dry surface, golden crust; wet surface, steam.

From there it is a normal sear. Heat a heavy stainless or cast-iron pan over medium-high with a high-smoke-point oil like avocado or grapeseed, and wait until it just smokes. Have your butter, garlic, thyme, and a warm plate within reach, because from the first sizzle the whole cook takes under five minutes.

• Lay the dry, seasoned scallops in the pan, spaced apart so they do not steam.
• Sear 2 to 3 minutes without touching them, until deeply golden underneath.
• Flip once, add butter, garlic, and thyme, and baste 1 to 2 minutes to about 145°F, until the centers are just opaque.
• Rest 1 minute off the heat, then serve.

Recipe: seared frozen scallops

Yields: 2 servings | Prep: 30 min | Cook: 6 min | Total: 36 min

Ingredients

• 1 lb frozen dry sea scallops (U10 or 10/20)
• 1 tablespoon high-smoke-point oil (avocado or grapeseed)
• 2 tablespoons unsalted butter
• 1 garlic clove, smashed
• 2 sprigs fresh thyme
• Kosher salt and black pepper
• 1 lemon, for serving

Instructions

1. Thaw the scallops fully: overnight in the refrigerator, or sealed in a bag under cold water for 20 to 30 minutes. Do not thaw at room temperature.
2. Pat the thawed scallops very dry, rest them on a dry towel 10 minutes, and pat again. Remove the small side muscle if it is still attached.
3. Heat a heavy skillet over medium-high with the oil until it just smokes. Season the scallops with salt and pepper.
4. Sear flat-side down, spaced apart, for 2 to 3 minutes without moving them, until deeply golden.
5. Flip, add the butter, garlic, and thyme, and baste 1 to 2 minutes until the centers are just opaque, about 145°F.
6. Rest 1 minute off the heat and serve with lemon.

How do you store frozen scallops and handle leftovers?

Keep them at 0°F or below at the back of the freezer, not in the door, where the temperature swings. Sealed in their original vacuum pack, well-glazed scallops hold their quality for months. Once you break that seal the clock speeds up: press the air out, reseal or vacuum-seal what you are not cooking, date the bag, and use it within about a month, since air dulls the flavor and lets the glaze sublimate away. Refreezing raw scallops is safe only if they thawed in the refrigerator and never came above 40°F, per USDA guidance, but each freeze sheds more water, which is one more reason loose IQF scallops beat a frozen block.

Once thawed, treat scallops like fresh seafood: keep them at 40°F or below and cook within a day or two, draining any water that collects and patting them dry again. Try not to refreeze thawed raw scallops, because the second freeze pushes out the very texture you are chasing. If plans change, cook them first, then refrigerate the cooked scallops and use them cold in a salad or pasta within a couple of days.

Which scallops sear best from frozen?

The scallops that sear best from frozen are the same ones that sear best fresh: large and dry-packed. Dry scallops have no sodium tripolyphosphate, so they are not waterlogged before you start, and a U10 or 10/20 size builds a crust before the center overcooks. Maine Shelled Lobster's Hokkaido scallops are large, sweet, and frozen without additives, and the rest of the wild-caught scallops are dry-packed too. Thaw, dry, and sear, and frozen scallops will hold their own against anything at the fish counter.

Frequently asked questions

Can you cook scallops from frozen?

You can, but you should not if you want a sear. Frozen scallops release water that steams them gray. Thaw first, pat dry, and then sear for a golden crust. In liquid, like a chowder, cooking from frozen is fine.

How do you thaw frozen scallops fast?

Seal them in a zip-top bag, press out the air, and submerge in cold water for 20 to 30 minutes. For the best texture, thaw overnight in the fridge. Skip the counter and skip hot water.

How long do you cook thawed scallops?

Sear 2 to 3 minutes on the first side and 1 to 2 minutes on the second while basting, until the center is just opaque, about 145°F.

Why are my frozen scallops watery?

Two reasons: they were not thawed and dried, or they are wet scallops treated with STP. Buy dry-packed scallops and dry them well before cooking.

Are frozen scallops as good as fresh?

Yes, when they are frozen fresh at their peak and thawed properly. Much of the fresh seafood at the counter was previously frozen anyway.

How long do frozen scallops last in the freezer?

In an unopened vacuum-sealed pack at 0°F or below, several months with no real loss in quality. Once opened, reseal tightly and use within about a month before freezer burn sets in.

Can I add frozen scallops straight to a soup or chowder?

Yes. In liquid the ice does not hurt anything. Add them frozen to a simmering pot and cook 5 to 7 minutes, until the centers are just opaque. Save the thawing for anything you plan to sear, broil, or grill.
