Why This Recipe Works

Seafood boils are a tradition in many Southern and coastal homes, but cooking one at home can feel intimidating. That’s why I love this oven-baked seafood boil in a bag method. By pre-cooking the potatoes, corn, and sausage, you ensure they’re perfectly done without turning mushy.

The seafood steams inside the oven bag, locking in flavor and keeping everything juicy. The buttery garlic-citrus sauce ties it all together with just the right balance of Cajun seasoning, citrus brightness, and a touch of heat. Best of all? The cleanup is practically effortless — no giant stockpot required.

Step-by-Step Seafood Boil In A Bag Recipe Instructions

Step 1 – Prep the Potatoes & Corn

Scrub 2 lbs of small potatoes until the water runs clear.

Boil until about two-thirds of the way cooked (still slightly firm). Drain.

Lightly oil 4 halved corn cobs with olive or avocado oil, season, and roast at 400°F for 5–6 minutes. This prevents mushy corn in the boil.

Step 2 – Prep the Lobster & Sausage

Using sharp kitchen scissors, cut the backs and undersides of 4 lobster tails, then split them in half. Clean thoroughly.

Slice 2–3 lbs andouille sausage into bite-sized pieces.

Sear in a cold skillet over medium heat until browned and flavorful (about 5 minutes). Remove sausage and set aside.

Step 3 – Build the Garlic Butter Sauce

In the same skillet, melt 2 sticks of butter.

Add 1–2 chopped onions, sautéing until softened.

Mash and stir in 1–2 heads roasted garlic and 2 tbsp fresh garlic until fragrant.

Pour in the juice of 1 orange and 1 lemon, then add 2 tbsp hot sauce, 1 tbsp Worcestershire sauce, and 1 tbsp chicken bouillon powder.

Season generously with AP seasoning and Lemon Bae seasoning (about 3–4 tbsp combined).

Add 1 cup chicken broth, simmer for 5–7 minutes until slightly reduced. Stir in ¼ cup fresh parsley. Taste and adjust seasoning.

Step 4 – Assemble the Seafood Boil Bag

Place a turkey roasting bag inside a foil pan or large casserole dish for support.

Add a layer of sauce to the bottom.

Layer in potatoes, corn, and sausage.

Add 3 lbs of crab legs and 4 halved lobster tails.

Pour the remaining sauce evenly over the ingredients. Tie the bag loosely, leaving room for steam.

Step 5 – Bake & Add Shrimp

Bake at 400°F for 30–35 minutes.

Open the bag carefully, add 2 lbs shrimp, reseal, and cook for another 8–10 minutes until shrimp turn pink and opaque.

Step 6 – Serve & Garnish

Open the bag, transfer to a large platter, and drizzle with extra sauce.

Garnish with fresh parsley and lemon wedges.

Serve hot with crusty bread to soak up the buttery garlic sauce.

Pro Tips for the Best Seafood Boil

• Pre-cook wisely: Parboiling potatoes and roasting corn prevents mushy textures.
• Balance flavors: Citrus juice cuts through the richness of the butter.
• Don’t overcook shrimp: Add them last to keep them juicy and tender.
• Bag support: Always place your turkey bag inside a roasting pan for safety.

What to Serve with a Seafood Boil

Seafood boils are a full meal on their own, but I love pairing them with:

• Garlic bread or French baguette (perfect for soaking up sauce)
• A crisp garden salad or coleslaw for freshness
• Chilled white wine, beer, or sweet tea
