If you’re a fan of The Boiling Crab, this Seafood Boil Pasta is going to taste incredibly familiar. The sauce is inspired by that iconic Viet Cajun garlic butter sauce that’s rich, buttery, garlicky, slightly sweet, and packed with Cajun spices. It has all the flavors you crave from a seafood boil, but instead of eating it straight from the bag, we’re tossing it with spaghetti so every noodle is coated in that addictive sauce.
When you order a seafood boil, there’s always a debate on the best way to enjoy all that extra sauce. Some people love dipping bread into it, serving it over steamed rice, or pairing it with potatoes. While those are all delicious, my favorite way is with pasta. The spaghetti soaks up every drop of that buttery garlic sauce, turning it into a complete meal while making sure none of that flavor goes to waste.
I also like to cook my shrimp and clams directly in the sauce instead of boiling them separately. As they cook, they release their natural sweetness into the butter sauce while soaking up all of those bold Viet Cajun flavors. It creates an even richer sauce and gives every piece of seafood more flavor than if it were simply boiled first.
If you’ve ever wished you could bottle up the sauce from The Boiling Crab and eat it with a bowl of pasta, this recipe is exactly that. It’s loaded with shrimp, snow crab, clams, sausage, and corn, making it the perfect combination of a classic seafood boil and a comforting pasta dinner. Every bite is buttery, garlicky, spicy, and guaranteed to satisfy your seafood boil cravings.

Frequently Asked Questions
Can I use frozen seafood?
Yes. Thaw the seafood completely and pat it dry before cooking for the best texture.
What pasta works best?
Spaghetti is my favorite because it absorbs the buttery sauce well, but linguine, fettuccine, or bucatini are also great choices.
Can I make this less spicy?
Absolutely. Reduce or omit the cayenne pepper and use less hot sauce while keeping the Cajun seasoning.
Can I make it ahead?
The sauce can be made one day in advance. For the best texture, cook the seafood and pasta fresh before serving.
How do I store leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days.
How do I reheat Seafood Boil Pasta?
Warm gently in a skillet over medium-low heat with a splash of chicken broth or butter until heated through.
Can I add other seafood?
Definitely! Lobster tails, mussels, scallops, crawfish, or king crab all work wonderfully.
Is MSG necessary?
No, but it’s highly recommended. MSG enhances the natural savory flavors of the seafood and creates a more restaurant-style seafood boil sauce.
