Sea Scallops vs Bay Scallops: Key Differences
Sea scallops are larger (1.5 to 2 inches, 10 to 30 per pound) and best for searing. Bay scallops are smaller (½ to ¾ inch, 50 to 100 per pound) and best for pasta and soups. Compare taste, price, and cooking time.
Quick Answer: Sea Scallops vs Bay Scallops
Sea scallops and bay scallops are both sweet, edible shellfish from the same family, but they differ in size, habitat, price, and best cooking method. Sea scallops measure 1.5 to 2 inches across with 10 to 30 per pound, and they are best for pan searing or grilling. Bay scallops measure ½ to ¾ inch across with 50 to 100 per pound, and they are best for pasta, soups, and casseroles.
Sea scallops live in deep offshore Atlantic waters at depths of 100 to 200 feet. Bay scallops live in shallow bays, estuaries, and seagrass beds along the eastern coast of North America and the Gulf of Mexico. NOAA Fisheries classifies the Atlantic sea scallop (Placopecten magellanicus) as one of the most valuable wild fisheries in the United States, while the bay scallop (Argopecten irradians) depends on healthy seagrass habitat.
The simple rule for buyers is this. Choose sea scallops when the scallop is the main dish. Choose bay scallops when the scallop is mixed into a recipe. For the best results at home, start with fresh North Atlantic scallop meat that is free from chemical treatments.

What Are Sea Scallops?
Sea scallops are the large, thick scallops most often served in restaurants. A single sea scallop measures about 1.5 to 2 inches in diameter, with 10 to 30 pieces per pound depending on grade. They come from the North Atlantic Ocean at depths of 100 to 200 feet and are harvested mainly by dredge or by divers.
Sea scallops have a firm, meaty texture and a clean sweet flavor with a light briny finish. Their size gives them enough surface area to form a deep golden crust when seared in a hot pan. Dry-packed sea scallops, which are not soaked in a sodium tripolyphosphate solution, brown better and release less liquid than wet-packed scallops. At Intershell, our chemical-free North Atlantic scallops are harvested by the F/V Bing Bing and F/V Hotate from the Gulf of Maine to east of Cape Cod.
NOAA Fisheries reports that the Atlantic sea scallop fishery is one of the most valuable wild scallop fisheries in the world, with landings centered in New Bedford, Massachusetts.
Best Uses for Sea Scallops
Sea scallops work best in dishes where each piece stands alone on the plate, including:
For sashimi or crudo, our live in-shell scallops deliver the sweetness and firmness needed for raw preparations.
What Are Bay Scallops?
Bay scallops are small, tender shellfish that measure ½ to ¾ inch across, with 50 to 100 pieces per pound. They live in shallow coastal waters along the eastern United States, with the largest populations in the Gulf of Mexico and along the mid-Atlantic and New England coasts. North Carolina Sea Grant notes that bay scallops need high-salinity seagrass beds to complete their life cycle, which makes them sensitive to coastal habitat loss.
Bay scallops have a softer texture and a noticeably sweeter taste than sea scallops. Because each piece is small, bay scallops cook in under one minute and are usually added near the end of a recipe to prevent overcooking.
Best Uses for Bay Scallops
Bay scallops work best in dishes where small, sweet pieces spread flavor throughout, including:
Main Difference Between Sea Scallops and Bay Scallops
The main difference between sea scallops and bay scallops is size. Sea scallops are roughly three times wider than bay scallops, and a pound of bay scallops contains three to five times more pieces. This size gap affects every other factor, including texture, cook time, plating, and price.
A sea scallop is thick enough to sear on both sides while keeping the center tender. A bay scallop is too small for a true sear and will overcook before a crust can form. This is why sea scallops dominate fine dining menus while bay scallops appear in family-style and mixed seafood dishes.
Taste Difference Between Sea and Bay Scallops
Both types share a naturally sweet seafood flavor, but the intensity and finish are different.
Sea scallops taste clean and sweet with a mild briny finish and a meaty bite. The flavor is rich enough to hold up against bold sauces, but most chefs recommend simple preparations to let the scallop shine.
Bay scallops taste sweeter and more delicate than sea scallops. Their small size and tender texture make them blend smoothly into sauces, soups, and pasta. They do not have the same firm bite as sea scallops, so they work best in dishes where soft texture is welcome.
Which tastes better depends on the dish. Sea scallops win for restaurant-style main courses. Bay scallops win for mixed recipes where sweet flavor should reach every bite.
Texture Difference
Sea scallops are firm, thick, and juicy when cooked correctly, with a meaty bite and a brownable surface. Bay scallops are soft, small, and tender, with a delicate texture that can turn rubbery in seconds if overcooked.
For a meaty seafood experience, sea scallops are the better choice. For a smooth, tender scallop that blends into a recipe, bay scallops are the better fit.
Size Difference and Scallop Count Grades
Scallops are sold by count per pound, using a grading system that tells buyers how many pieces are in one pound. The lower the number, the larger the scallop.
Common sea scallop grades:
Common bay scallop counts: 50 to 100 pieces per pound, sometimes up to 120 per pound for the smallest grade.
For pan searing, U/10 to U/15 sea scallops give the best plate presentation. For pasta or soup, 20/30 sea scallops or any bay scallop grade works well. Intershell offers our scallop frying kit with medium 20/30 scallops for home cooks who want the right size for crispy fried bites.
Cooking Difference: Sea vs Bay Scallops
Sea scallops and bay scallops require different cooking methods because of their size.
How to Cook Sea Scallops
America's Test Kitchen recommends pulling scallops at 115°F because carryover heat adds another 10 to 15 degrees after the pan. The FDA safety baseline is 145°F, which produces a firmer texture and is recommended for pregnant, elderly, or immunocompromised diners.
How to Cook Bay Scallops
The FDA confirms scallops are properly cooked when the flesh becomes firm, pearly, and opaque. Bay scallops can turn rubbery in under a minute if left on the heat too long.
Which Scallops Are Better for Searing?
Sea scallops are better for searing. Their 1.5 to 2 inch surface provides enough contact with the pan to develop a deep Maillard crust before the center overcooks. Bay scallops are too small to sear properly because they cook through before a crust can form.
For the best sear, choose dry-packed sea scallops. Wet-packed scallops are treated with sodium tripolyphosphate, which causes them to absorb water and release that water in the pan. This steaming effect prevents browning and dilutes the flavor. Our chemical-free dry scallop meat is sold in its natural state with no added solutions.
Which Scallops Are Better for Pasta?
Bay scallops are usually better for pasta. Their small size lets sweet scallop flavor spread through every forkful, and they cook in under a minute when added to a hot sauce. Sea scallops can also be used with pasta, but most chefs sear them separately and place them on top of the finished dish.
Quick rule:
Which Scallops Are Better for Soup or Chowder?
Bay scallops are better for chowder, bisque, and seafood stew. Their bite-size shape fits naturally in a spoonful of broth, and their sweet flavor blends well with cream or tomato bases. Sea scallops can work in soup if cut into quarters or smaller pieces, but whole sea scallops feel oversized in a bowl.
Which Scallops Are More Expensive?
Sea scallops cost more than bay scallops in most US markets. As of 2026, fresh dry-packed sea scallops range from $24 to $49 per pound, while bay scallops average $15 to $28 per pound. Wild-caught bay scallops from the Gulf of Mexico can exceed $35 per pound during peak demand.
Price is driven by several factors:
Price alone is not the best measure of value. A wet-packed scallop at a lower price can lose 20 to 30 percent of its weight as water during cooking, which often makes dry-packed the better cost per usable pound.

Are Sea Scallops and Bay Scallops Interchangeable?
Sea scallops and bay scallops are interchangeable in some recipes but not all. The substitution depends on the cooking method and how the scallop is plated.
Substitution rules:
Dry Scallops vs Wet Scallops: Why It Matters
Beyond choosing between sea and bay, buyers should also check whether scallops are dry-packed or wet-packed. This factor often matters more than the type of scallop.
Dry-packed scallops are sold in their natural state without any preservative solution. They have a creamy, off-white color, sometimes with a slight pink or beige tint. Dry scallops brown well, release minimal liquid, and taste cleaner.
Wet-packed scallops are soaked in a sodium tripolyphosphate (STPP) solution that helps them retain water. They appear bright white and plump on display, but they release excess liquid in the pan, prevent browning, and shrink significantly during cooking.
For pan searing, dry-packed sea scallops give the best results. For soups and casseroles where browning is not the goal, wet-packed scallops are acceptable but still inferior in flavor. Intershell's North Atlantic scallops are 100 percent chemical-free and never soaked in STPP.

Common Mistakes When Cooking Scallops
Mistake 1: Not drying the scallops. Wet scallops steam instead of sear. Pat both sides with paper towels and let them air-dry uncovered in the fridge for 10 minutes if possible.
Mistake 2: Overcrowding the pan. When the pan is too full, the temperature drops and scallops release steam. Leave at least one inch of space between each piece, or cook in batches.
Mistake 3: Cooking too long. Scallops cook in under four minutes total. Past 130°F internal temperature, the muscle fibers tighten and the texture turns rubbery.
Mistake 4: Using low heat. Sea scallops need a hot pan at roughly 450°F surface temperature to form a proper crust. Medium heat will not brown them.
Mistake 5: Treating bay scallops like sea scallops. Bay scallops cook in 30 to 60 seconds. The same time that browns a sea scallop will turn a bay scallop into rubber.
Final Verdict: Sea Scallops or Bay Scallops?
Sea scallops and bay scallops are both excellent shellfish, but they serve different roles in the kitchen. Sea scallops are large, meaty, and built for searing as a main course. Bay scallops are small, sweet, and built for mixing into pasta, soups, and casseroles.
For pan-seared dinners and restaurant-style plates, sea scallops win. For quick weeknight seafood and dishes where the scallop is one of many ingredients, bay scallops win. For either type, dry-packed scallops with a clean smell and firm texture deliver the best cooking results.

FAQs
Are sea scallops better than bay scallops?
Sea scallops are better for searing, grilling, and main course plating because they are larger and meatier. Bay scallops are better for pasta, soups, stews, and recipes that need small, sweet pieces.
Are bay scallops sweeter than sea scallops?
Yes. Bay scallops have a sweeter and more delicate flavor than sea scallops. Sea scallops are also sweet but carry a stronger briny finish and a firmer texture.
What size are sea scallops?
Sea scallops measure 1.5 to 2 inches in diameter, with 10 to 30 pieces per pound depending on grade. Colossal U/10 sea scallops contain fewer than 10 pieces per pound.
What size are bay scallops?
Bay scallops measure ½ to ¾ inch in diameter, with 50 to 100 pieces per pound. Some grades reach up to 120 per pound.
Can I use bay scallops instead of sea scallops?
You can use bay scallops in pasta, soups, chowder, stew, and casseroles. They are not a good substitute for pan-seared sea scallops because they are too small to form a proper crust.
Can I use sea scallops instead of bay scallops?
Yes, if you cut them into quarters or smaller pieces. Sea scallops will work in soups, pasta, and casseroles but need a slightly longer cook time than bay scallops.
Which scallops are best for pan searing?
Sea scallops are best for pan searing, especially dry-packed U/10 to U/15 grades. They are large enough to brown deeply without overcooking the center.
Which scallops are best for pasta?
Bay scallops are usually best for pasta because they are small, sweet, and cook in under one minute when added to hot sauce. Sea scallops also work when seared and placed on top.
What temperature should scallops be cooked to?
The FDA recommends an internal temperature of 145°F for food safety. Many chefs pull scallops at 115°F and let carryover heat bring them to 125°F to 130°F for tender texture. America's Test Kitchen confirms this 115°F pull point produces ideal final doneness.
How do you know when scallops are cooked?
Scallops are done when the flesh turns firm, pearly, and opaque. The FDA lists these visual cues for scallops, shrimp, crab, and lobster. Overcooked scallops feel rubbery and shrink.
Why do scallops get rubbery?
Scallops turn rubbery when the internal temperature climbs past 130°F. The muscle fibers tighten quickly past that point. Pull scallops off the heat as soon as they turn opaque and feel firm to the touch.
Are dry scallops better than wet scallops?
Yes. Dry scallops are not soaked in sodium tripolyphosphate, so they brown better, release less liquid, and taste cleaner. Wet scallops absorb water that releases in the pan, which prevents searing. Intershell sells only chemical-free dry scallops.
How much do scallops cost in 2026?
Fresh dry-packed sea scallops cost $24 to $49 per pound in the US, while bay scallops average $15 to $28 per pound. Prices peak in November and December and soften from June through September.
What is the biggest difference between sea scallops and bay scallops?
Size is the biggest difference. Sea scallops are 1.5 to 2 inches across with 10 to 30 per pound. Bay scallops are ½ to ¾ inch across with 50 to 100 per pound. Size then drives texture, cook time, price, and best use.
