How to Make Garlic Butter Cajun Seafood Boil

  1. In a large pot, bring water to a boil. Add the baby potatoes and cook for about 10 minutes, or until tender.
  2. Add the corn and cook for an additional 5 minutes until it’s bright and tender.
  3. Carefully add the crab legs and mussels to the pot. Cook for 5 minutes until the mussels open and the crab legs are heated through.
  4. Add the shrimp and cook for another 3-4 minutes, or until they turn pink and opaque.
  5. In a separate saucepan, melt the butter over medium heat. Add the minced garlic, Cajun seasoning, lemon juice, cayenne pepper (if using), salt, and pepper. Stir and cook for 2-3 minutes until fragrant.
  6. Drain the seafood and vegetables, then return them to the pot. Pour the garlic butter mixture over the seafood and toss to coat evenly.
  7. Serve hot, garnished with fresh parsley and lemon wedges on the side. Enjoy!

Substitutions & Additions

  • If shrimp isn’t your thing, feel free to use scallops or even fish.
  • Swap out the potatoes for sweet potatoes for a unique twist.
  • For a touch of sweetness, add some sliced sausage into the mix.
  • Experiment with different seafood like clams or lobster for a luxurious upgrade.

Tips for Success

  • Don’t overcook the shrimp; they only need a few minutes until they turn pink.
  • Make sure your mussels are fresh and discard any that don’t open during cooking.
  • You can prep all the ingredients ahead of time to make the cooking process quicker.

How to Store Garlic Butter Cajun Seafood Boil

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Just reheat gently on the stove or in the microwave. However, the seafood is best enjoyed fresh, so try to savor it all in one sitting if you can!

FAQs
