Substitutions and Variations

King crab legs are another option, but they’re more expensive, tougher to crack and you’ll definitely need crab leg crackers (here) to open them.

King crabs have much thicker legs so they come individually rather than in clusters. Also, they’re not as easy to find as snow crab legs, which can usually just be cracked with your hands.

As for the other seasonings, swap the Old Bay for your favourite seafood seasoning if you like, perhaps Cajun seasoning. And if you’re using unsalted butter for the dipping sauce, you might want to add a pinch of salt, but taste it first.

How to Serve Easy Baked Crab Legs

Enjoy this delicious recipe warm from the oven and give everyone their own melted butter dip and a wedge of lemon. It goes well with crusty bread or a simple tossed green salad.

Keep the sides light and simple because the garlic butter is very rich and you’ll want a nice contrast. Mashed potatoes, boiled potatoes or steamed asparagus would also be good on the side.

You might like to cook some other proteins too, such as fresh shrimp or another kind of fresh seafood, or even something different like andouille sausage.

How to Store Baked Crab Legs

Store: The cooked crab should keep for up to 3 days in an airtight container in the fridge.
Freeze: Cooked crab legs can be frozen for up to 3 months and thawed overnight in the fridge.
Reheat: Reheat crab legs about 12 minutes in the oven preheated to 350 degrees F if the crabmeat is still in the shell, or warm up the crabmeat if it’s out of the shell in a skillet with a splash of oil or a little butter – it will take about 4 minutes. Heat crab legs until they’re quite warm but not piping hot, or else you risk them drying out.

Baked Crab Legs FAQs

What can you do with crab leg leftovers?

There are plenty of things you can make, such as crab cakes, crab bisque, crab salad, or even homemade sushi.

Can you make this with fresh crab legs?

If you’re not using flash frozen crab legs, the other option is to deal with live crab, because crab must either be cooked right away or frozen. This is why it’s easier to find frozen crab legs. Live crab should be boiled so, unless you especially want to work with live crab, just grab a pack of flash frozen crab legs instead – it’s so much easier and still comes out sweet, moist and tender.
