How to Prepare Cajun Seafood Boil with Garlic Butter Sauce in Under an Hour

1. Prep the seafood: Clean and prepare all your seafood. If using crab legs, thaw if frozen.
2. Boil the seafood: Bring seafood broth or water seasoned with Cajun spice to a boil in a large pot. Add potatoes or corn if using, cooking for about 10 minutes first.
3. Add seafood: Add shrimp, mussels, and crab legs to the boiling pot. Cook for about 5-7 minutes until shrimp turn pink and mussels open. Remove and set aside.
4. Make the garlic butter sauce: While seafood boils, melt butter in a small saucepan over medium heat. Add minced garlic and cook 30 seconds until fragrant. Stir in lemon juice and extra Cajun seasoning if desired.
5. Combine & serve: Pour garlic butter over the cooked seafood or serve on the side for dipping. Garnish with fresh parsley and lemon wedges.

Chef’s Tips for a Perfect Seafood Boil

• Use fresh seafood: Fresh or properly thawed seafood yields the best flavor and texture.
• Adjust spice level: Add more Cajun seasoning or hot sauce for extra heat.
• Don’t overcook: Remove seafood promptly once cooked to avoid tough or rubbery textures.

Variations & Substitutions

• Vegan: Use plant-based seafood substitutes and vegan butter or olive oil.
• Extra flavor: Add sliced sausage, corn, or potatoes boiled with seafood for a classic seafood boil experience.
• Less spice: Reduce Cajun seasoning and hot sauce for milder flavor.

Serving & Pairings

• Serve with crusty bread, crusty baguette, or garlic bread to soak up excess sauce.
• Pair with chilled white wine, cold beer, or fresh fruit for a festive vibe.
• Enjoy with a side salad for a balanced meal.

Leftovers & Storage Tips

• Store leftovers in airtight containers in the fridge for up to 2 days.
