How to Make Cajun Seafood Boil with Garlic Butter Sauce
Step 1: Prepare the Broth
In an extra large stockpot or Dutch oven over medium-high heat, combine the water and beef broth (if using). Bring it to a boil. Then season with Creole Cajun seasoning, Old Bay seasoning, and hot sauce to taste. Add onion slices and lemon wedges. Stir well to combine. Let boil for 15 minutes.
Step 2: Cook Sausage and Potatoes
Carefully add andouille sausage rounds and baby potatoes into the pot. Stir well to combine. Cook for 15-20 minutes until potatoes are fork-tender.
Step 3: Add Crab, Shrimp, and Corn
Gently nestle snow crab clusters into the pot along with shrimp and corn on the cob. Ensure everything is submerged in broth; stir carefully. Continue boiling for another 5-7 minutes until shrimp turns pink.
Step 4: Make Garlic Butter Sauce
On a separate burner, in a small saucepan over medium heat, combine butter, garlic, lemon juice, Old Bay seasoning, parsley, Creole Cajun seasoning, smoked paprika, and hot sauce to taste. Stir until butter melts and sauce combines well; simmer about 5-7 minutes then remove from heat.
Step 5: Assemble Your Seafood Boil
Line an extra large baking sheet with foil/parchment paper (or newspaper if you prefer!). Use a spider strainer to remove seafood boil contents from the pot onto the prepared baking sheet along with hard boiled eggs (if using). Discard onion/lemon bits.
If desired, thin out your garlic butter sauce by adding some seafood boil broth. Pour garlic butter sauce over seafood boil contents. Toss everything together using hands (gloves recommended).
Step 6: Serve!
Serve this Cajun seafood boil as-is on the baking sheet or divide it onto individual plates if preferred. Enjoy immediately with extra lemon wedges on the side! Be sure to savor every bit of that delicious garlic butter sauce!
