Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 teaspoons chicken bouillon paste
1 tablespoon Cajun seasoning
1 tablespoon Old Bay seasoning
2 pounds red potatoes, cut in half
1 pound smoked andouille sausage, cut into large chunks
3 ears of corn, cut into thirds
2 pounds jumbo shrimp, deveined
3 pounds snow crab legs
1 pound lobster tails (optional)
1/2 cup beer
Seafood Boil Sauce:
2 cups salted butter
1 medium onion, finely chopped
8 cloves garlic, minced
1/4 cup Cajun seasoning
2 tablespoons Old Bay seasoning
1 tablespoon onion powder
1 1/2 teaspoons brown sugar
1/2 tablespoon red pepper flakes
1 cup chicken stock
2 tablespoons fresh lemon juice
1 tablespoon fresh parsley, chopped
1 tablespoon fresh chives, chopped (optional)
Directions
Prepare the oven bags. Place one oven-safe turkey bag inside an aluminum pan or large baking dish. Insert a second bag inside the first to double bag and prevent leaks. Open the bags wide for easy filling.
Boil the vegetables. Bring a large pot of water to a boil over medium-high heat. Add chicken bouillon paste, Cajun seasoning, and Old Bay seasoning. Stir well. Add the halved red potatoes and corn. Boil for 12–15 minutes, until the potatoes are fork-tender but not falling apart. Drain and set aside.
Preheat the oven to 400°F (200°C).
Brown the sausage. In a large skillet over medium heat, add a small drizzle of oil. Cook the sausage pieces for about 5 minutes, until lightly browned. Remove from the skillet and set aside.
Make the sauce. In the same skillet, melt the butter over medium heat. Add chopped onion and cook for 3–5 minutes until softened and fragrant. Stir in the minced garlic and cook for 2 more minutes.
Add seasonings. Stir in Cajun seasoning, Old Bay seasoning, onion powder, brown sugar, and red pepper flakes. Cook for 5 minutes, stirring frequently. Pour in the chicken stock and bring to a boil. Reduce to a simmer and cook for 6–8 minutes until slightly thickened. Remove from heat and stir in lemon juice, parsley, and chives.
Assemble the bag. Pour the beer into the bottom of the oven bag. Add about 1 cup of the seafood boil sauce. Layer in the potatoes and corn first. Add the browned sausage and crab legs on top. Pour about 2 more cups of sauce over everything.
Seal and bake. Loosely tie the bag to allow slight steam expansion. Gently shake the bag to coat ingredients evenly. Bake for 15 minutes.
Add shrimp and lobster. Carefully open the bag, add shrimp and lobster tails, reseal, and bake for another 8–12 minutes, until shrimp are pink and slightly curled and lobster is bright red.
Rest and serve. Let the bag rest for 10 minutes before opening to allow flavors to settle and steam to reduce. Garnish with extra parsley and lemon wedges. Serve with remaining sauce on the side.
Servings and timing
Servings: 6 to 8 people
Prep time: 30 minutes
Cook time: 35 to 40 minutes
Rest time: 10 minutes
Total time: About 1 hour 15 minutes
Variations
Add mussels or clams. These shellfish steam beautifully inside the bag and absorb the flavorful sauce.
Include crawfish. Perfect for a Southern-inspired twist.
Add hard-boiled eggs. Peeled eggs soak up the sauce and add extra richness.
Make it milder. Reduce the Cajun seasoning and red pepper flakes for a less spicy version.
Try lemon pepper seasoning. Swap some of the Cajun seasoning for lemon pepper if you prefer a citrus-forward flavor.
Use chicken broth instead of beer. If you prefer not to cook with beer, substitute with additional chicken stock.
Storage/Reheating
Storage: Allow leftovers to cool completely. Store seafood and vegetables in an airtight container in the refrigerator for up to 2 to 3 days.
Reheating on the stovetop: Place leftovers in a pot with a splash of water or broth. Cover and heat gently over medium-low heat until warmed through.
Reheating in boiling water: Seal leftovers in an oven-safe or heat-safe bag and submerge in boiling water for 10–15 minutes until heated evenly.
Avoid microwaving if possible, as it can overcook the seafood and make it rubbery.
FAQs
Why cook seafood boil in a bag instead of a large pot?
Cooking in a bag locks in steam and flavor, ensures even seasoning, and reduces cleanup compared to a traditional open boil.
Can I use frozen seafood?
Yes, but thaw completely and pat dry before adding to the bag to prevent excess water from diluting the sauce.
How do I know when the shrimp are done?
Shrimp turn pink and opaque and curl into a loose “C” shape when properly cooked.
How do I prevent the bag from bursting?
Always double bag and avoid overfilling. Leave some space for steam to circulate.
Can I make this ahead of time?
You can prepare the sauce and pre-boil the vegetables ahead of time. Assemble and bake just before serving for best results.
What type of oven bags should I use?
Use heat-resistant, oven-safe turkey bags designed for temperatures up to 400°F.
Can I skip the lobster?
Yes, the lobster is optional. The dish is still delicious with shrimp and crab alone.
How spicy is this recipe?
It has a medium spice level. You can adjust by increasing or decreasing Cajun seasoning and red pepper flakes.
Can I cook everything at once?
It’s best to add shrimp and lobster later since they cook faster than potatoes and crab legs.
What should I serve with seafood boil in a bag?
Serve with crusty bread, a fresh green salad, or rice to soak up the flavorful butter sauce.
