Step 4: Combine with Pasta

Tips

  • Substitute shrimp for crawfish if crawfish are unavailable.
  • Use real cream instead of soup for a richer, less processed sauce.
  • Add bell peppers for extra Cajun flavor and color.
  • Spice it up with cayenne or extra Tony Chachere’s.
  • Swap Velveeta for shredded mild cheddar if desired.
  • Finish under the broiler for a lightly browned Parmesan topping.
  • Use fresh fettuccine for a more tender texture.
  • Make ahead and refrigerate before baking for easy entertaining.
