Creamy vs. Classic Version

Classic Garlic Butter Style:
Skip the cream and use pasta water for a glossy, lighter sauce.

Creamy Cajun Version:
Add cream and a little extra Cajun seasoning for a richer Southern-style pasta.


Tips for the Best Flavor

  • Don’t overcook shrimp — they cook fast.
  • Use fresh lemon juice to brighten the rich butter sauce.
  • Add corn kernels or sliced smoked sausage for a true seafood boil twist.
  • Want heat? Add red pepper flakes or a dash of hot sauce.

Storage & Reheating

Store leftovers in an airtight container for up to 3 days.
Reheat gently on the stovetop with a splash of cream or broth to loosen the sauce.


Make It a Meal

Serve with:

  • Crusty sourdough bread
  • A simple green salad
  • Roasted asparagus
