Seafood Boil…in a Bag?

Ok, yes! We’re putting bags in the oven. But please don’t put ordinary ziplock bags in the oven! Nylon, heat-resistant oven bags (they usually stand up to 400℉/205℃) work fine for our seafood recipe.

I love oven bags because they make almost any meat juicy and tender by locking in liquid as the meat cooks. A seafood boil-in-a-bag recipe is no exception. We’re making the most of our buttery garlic sauce by cooking everything in the oven bags.

 Sauce ingredients for Seafood Boil in a Bag

  1. Seafood – Snow crab legs and shrimp are my favorite options, but you could add other seafood. I’ve tried lobster tail and mussels, which were delicious. 
  2. Vegetables – Potatoes and corn are a must for me, along with chopped red onion.
  3. Sausage – Andouille sausage was made for seafood boils! You could use another sausage variety, but I highly recommend andouille when pairing sausage with seafood. 
  4. Eggs – Hard-boiled eggs don’t crop up in every seafood boil in a bag, but it’s a beautiful addition. Try and see if it isn’t amazing! 
  5. Garlic Butter Sauce – Now for the secret sauce. Melted butter, garlic cloves, chicken broth, Old Bay and Creole seasoning, paprika, and cayenne make for the most sensational butter sauce you’ve ever tasted.
  6. Oven Bags – This isn’t technically an ingredient. But you do need either large oven bags or small ones for this recipe.

How to Make Seafood Boil in a Bag

Cook the potatoes and corn, fry the sausage, and saute the aromatics

Prepare the Ingredients 

  • Heat – Bring a large pot with water on the stove to boil on medium-high. The pot should be large enough to fit the potatoes and corn. 
  • Add Veggies – Rinse the potatoes and then add them, alongside the corn, to the pot, season with salt and leave to boil for 12-15 minutes. (Photo 1)
  • Check if the potatoes are ready by piercing them with a fork. They should be fork-tender but stay intact. And the corn will change in color from a lighter to a more intense yellow, with fuller, plumper kernels. When both are well cooked, remove them from the water and set them aside. 
  • Cook the Sausage – Slice the andouille sausage into ½-1″ pieces diagonally. Heat a skillet or saucepan over medium-high heat, and cook until lightly browned (3-5 minutes). Transfer the sausage to a plate and set it aside. (Photo 2)

Make the Butter Sauce

  • Saute Veggies – Add butter to the saucepan. When the butter melts, add the diced red onion and garlic. Saute for 5 minutes or until the onion is translucent. (Photos 3-4)
  • Season – Next, add the chicken broth, Old Bay seasoning, Creole seasoning, paprika, and cayenne pepper. Mix well. Then, reduce the heat to low and cook for 5-7 minutes. (Photo 5)
  • Final Stretch – Season with salt and pepper to taste, and add fresh lemon juice and parsley. Mix well and cook for another minute. Turn off the heat and set aside. (Photo 6)
Finish the sauce, assemble the goodness, and bake

Assemble the Bags

  • Preheat the oven to 400℉/205℃. Place the bags in a large bowl to stabilize while filling. 
  • Assemble – Add the thawed snow crab legs, deveined shrimp, andouille sausage, hard-boiled eggs, potatoes, and corn to the oven bag (divide the ingredients between the bags evenly). (Photo 7)
  • Add Sauce – Drizzle the butter sauce throughout and tie the oven bag to seal it. Toss the contents around in the bag to ensure the sauce coats everything. (Photo 7)

Bake the Seafood Boil

  • Bake – Place the bags on a baking sheet pan or dish and place them in the oven. Bake for 20-25 minutes, flipping the bags halfway during cooking. (Photo 8)
  • Rest – Remove the bags from the oven and let rest for 5 minutes before opening (be careful of the hot steam). 
  • Serve – Garnish with parsley and lemon wedges, and your seafood is ready.

FAQs

Seafood bake vs. seafood boil

This recipe is still a seafood boil, even though it’s going in the oven. That’s because the bag allows the seafood to steam and simmer in all those lovely juices. You leave a seafood bake uncovered in the oven.

Can I use frozen seafood for seafood boil in a bag?

Sure! Just make sure you thaw your seafood before adding it to the bag to cook in the oven.

Why put eggs in a seafood boil?

They add extra protein to the meal and soak up all those amazing flavors, making them extra tasty. Plus, they look pretty with all the other ingredients. 😍
