Crab legs are a delicious and indulgent seafood treat that many people love. When cooked just right, their sweet, tender meat literally melts in your mouth. But getting the oven time just perfect for crab legs can be tricky. Undercook them and you’ll be fighting to extract meat from rubbery shells. Bake them too long and they’ll be dry and chewy. So how long do you actually need to cook crab legs in the oven?
The timing depends on several factors:
- Type of crab leg
- Size of crab legs
- Whether frozen or thawed
- Oven temperature
In this article I’ll provide a detailed guide on how long different types of crab legs take to cook in the oven. I’ll also share my top tips for achieving tender juicy, restaurant-quality crab legs at home.
Factors That Impact Oven Cook Times
Type of Crab Leg
- King crab legs – Largest variety with thick leg segments. Take the longest to cook.
- Snow crab legs – Medium size with thinner leg segments. Cook more quickly than king crab.
- Dungeness crab legs – Smallest legs that cook the most quickly.
Size of Crab Legs
- Larger legs – Require longer cook times.
- Smaller legs – Take less time to cook through.
Frozen vs. Thawed
- Frozen – Will take nearly twice as long to cook as thawed crab legs.
- Thawed – Cooks much faster since it’s already at refrigerator temperature.
Oven Temperature
- Higher heat (400°F to 425°F) – Cooks quicker but can dry out the meat.
- Lower heat (350°F to 375°F) – Requires longer time but keeps the meat juicy.
Now let’s look at specific oven times for popular crab leg varieties.
Recommended Oven Cook Times
Follow my recommended oven cook times below for tender, perfectly cooked crab legs.
King Crab Legs
- Frozen – Bake at 400°F for 18-22 minutes
- Thawed – Bake at 375°F for 10-12 minutes
King crab legs are the largest variety and need ample time to cook through. Their thick meat retains heat well so can stand up to higher oven temps. Go lower and slower with thawed legs to prevent overcooking.
Snow Crab Legs
- Frozen – Bake at 400°F for 14-18 minutes
- Thawed – Bake at 375°F for 7-10 minutes
Snow crab legs are smaller than king but larger than Dungeness, Their thinner segments cook faster Adjust times based on leg size,
Dungeness Crab Legs
- Frozen – Bake at 425°F for 12-15 minutes
- Thawed – Bake at 400°F for 5-8 minutes
Dungeness legs are the smallest variety, so they bake quickly. Use higher heat but watch closely to avoid drying them out.

Frequently Asked Questions
Still have questions about how to cook crab legs in the oven? Here are answers to some common questions:

You’ll know the crab legs are fully cooked when you can smell them and the meat is hot throughout with a reddish-pink, juicy appearance.
Can you cook frozen crab legs in the oven?
Yes, you can bake frozen crab legs in the oven. They will just take longer to cook through than thawed legs.
How long should I cook pre-cooked frozen crab legs?
I recommend baking frozen pre-cooked king crab legs at 400°F for 18-22 minutes, snow crab for 14-18 minutes, and Dungeness for 12-15 minutes.
Should crab legs be baked in foil?
You can bake crab legs in foil to help retain moisture. Just be sure to poke holes in the foil so steam can escape. I recommend baking for a portion of time uncovered for a nice browned exterior.
What temperature is best for baking crab legs?
The ideal oven temperature for crab legs is 375°F to 400°F. Higher heat cooks them faster but may dry them out. Lower heat keeps them moist but requires more time.

Yes, it’s easy to overcook crab legs in the oven if baked for too long. That’s why it’s important to follow recommended cook times and check for doneness. Immediately remove them once the meat is opaque and flaky.
The Bottom Line
Baking crab legs in the oven results in tender, deliciously juicy meat when you follow proper cook times. Adjust temperatures and baking times based on the type, size and whether legs are frozen or thawed. Monitor closely near the end of cooking and remove promptly once opaque and flaky.
