How to Make Oven-Baked Cajun Seafood Boil

This Oven-Baked Cajun Seafood Boil follows a simple, organized process that works perfectly for an oven-bag seafood boil. Parboiling the vegetables first helps everything finish cooking evenly once it hits the oven.

Step	What to Do
Prep	Preheat the oven to 400°F. Bring 6 cups of water to a boil and cook corn and potatoes for 18–20 minutes, then drain.
Assemble	Place the oven bag in a large pan. Add potatoes, corn, andouille sausage, crab legs, and shrimp.
Season	Season generously with Old Bay, lemon pepper, and paprika. Add garlic, parsley, and lemon slices.
Finish	Pour in melted butter and chicken broth, seal the bag, gently shake, and bake for 30–35 minutes.

After baking, carefully open the bag and transfer everything to a serving platter. Spoon the buttery juices over the top, sprinkle with remaining parsley, add extra seasoning if desired, then serve hot. This method creates a tender crab and shrimp boil in an oven bag with rich garlic butter flavor.

Pro Tips for the Best Results

A few small details make a big difference with this Oven-Baked Cajun Seafood Boil. First, parboil the potatoes and corn until tender before baking. That step helps them finish cooking at the same pace as the seafood. When seasoning, stay generous. The oven bag traps moisture, so the spices spread evenly instead of drying out.

Handle the bag gently once the crab legs go in. Their sharp edges can tear plastic if you shake too hard. A light toss works best for spreading the butter and seasoning. For a deeper flavor, focus on garlic and butter, which gives this dish the appeal of a garlic butter crab boil. If you enjoy that flavor profile, our Cajun Seafood Boil with Garlic Butter Sauce offers more inspiration.

Finally, open the bag carefully after baking to avoid hot steam, then spoon the juices over the seafood right away.

Serving Suggestions for Oven-Baked Cajun Seafood Boil

This Oven-Baked Cajun Seafood Boil shines when served family-style. Spread everything across a large platter, then drizzle the buttery juices over the top so every bite stays flavorful. Warm bread or rolls work well for soaking up the sauce, especially when the seasoning leans bold.

For balance, add something fresh on the side. A crisp salad or light vegetable dish cuts through the richness and keeps the meal feeling comfortable rather than heavy. When you plan a Cajun-themed spread, this dish pairs nicely with other Southern-inspired favorites. Our Easy Cajun Seafood Boil with Corn and Potatoes fits beautifully on the same table for larger gatherings.

Whether you serve it for a weekend dinner or a casual celebration, this oven-baked Cajun seafood boil invites everyone to slow down, share food, and enjoy the moment
