Factors That Affect Grilling Time

Several factors impact the cooking time needed for crab legs in foil on the grill:

  • Type and size of crab – King crab legs take longer than snow crab. Larger legs require more time than smaller legs or pieces.

  • Thickness of legs – Thicker legs need longer grilling time than thin legs.

  • Precooked vs. raw – Raw crab legs take much longer to cook through than precooked frozen legs that just need reheating.

  • Quantity being grilled – Grilling multiple foil pouches of crab legs on the grill simultaneously increases total grilling time

  • Grill temperature – Hotter grills cook crab faster while lower heat requires longer cooking time.

  • Weather conditions – Grilling in cold or windy weather increases total cooking time,

How to Tell When Crab Legs Are Done

Since most crab legs are sold precooked, visually checking for doneness is key:

  • Shell turns bright red/orange indicating heat has penetrated.

  • Meat is opaque throughout rather than translucent.

  • Juices run clear when shell is pierced versus milky white.

  • Meat feels firm when pressed with tongs rather than spongy.

The crab meat should be heated through but not overcooked or dried out.

Recommended Grilling Times

King crab legs

  • 1 lb – 15 to 20 minutes
  • 2 lbs – 20 to 25 minutes
  • 3+ lbs – 25 to 30 minutes

Snow crab legs

  • 1 lb – 10 to 15 minutes
  • 2 lbs – 15 to 20 minutes
  • 3+ lbs – 20 to 25 minutes

Raw crab legs

  • 1 lb – 30 to 35 minutes
  • 2 lbs – 35 to 40 minutes
  • 3+ lbs – 40 to 45 minutes

These times are based on a medium-hot grill around 400°F. Use foil to avoid overcharring the shells. Adjust times as needed based on quantity, size, and grill temperature.

Grilling Process

  1. Preheat grill to medium-high heat, around 400°F.

  2. Pat crab dry. Season lightly with salt, pepper, and/or garlic powder if desired.

  3. Place crab legs in center of heavy duty foil and wrap tightly in packet.

  4. Grill foil packets for recommended time, turning once halfway through.

  5. Check for doneness using visual tests. Grill longer if needed.

  6. Remove from grill and unwrap carefully to avoid steam burns.

  7. Serve with melted butter, lemon wedges, and favorite sauces.

Grilling Tips

  • Use two sheets of foil or heavy duty foil to avoid tearing.

  • Create a loose packet vs. wrapping crab tightly in foil.

  • Allow 5-10 minutes extra grilling time if making multiple foil pouches.

  • Turn packets once halfway through for even heating.

  • Open packets away from face and body to avoid steam burns.

  • Check for doneness early to avoid overcooking.
