Ingredients
  

  • 1 lb crawfish tails peeled and cooked
  • 2 tbsp unsalted butter
  • 1 tbsp olive oil
  • 1 small onion finely chopped
  • 3 cloves garlic minced
  • 1/2 green bell pepper chopped
  • 1/2 cup celery finely chopped
  • 1 tsp Cajun seasoning
  • 1/2 tsp paprika
  • 1/4 tsp cayenne pepper optional, for heat
  • Salt and pepper to taste
  • 1 cup heavy cream
  • 1/2 cup chicken or seafood broth
  • 1/4 cup grated Parmesan cheese optional
  • 1 tbsp lemon juice
  • 2 tbsp chopped fresh parsley

Instructions
 

  • Sauté aromatics: In a large skillet over medium heat, melt butter and olive oil. Add chopped onion, garlic, celery, and bell pepper. Cook for 4–5 minutes until softened and fragrant.
  • Add seasoning: Stir in Cajun seasoning, paprika, cayenne (if using), salt, and pepper. Cook for another 1–2 minutes to toast the spices.
  • Deglaze and simmer: Pour in broth and bring to a simmer. Let it cook for 3–4 minutes to reduce slightly.
  • Creamy base: Stir in the heavy cream and reduce heat to low. Simmer for 5–6 minutes, stirring occasionally, until sauce thickens slightly.
  • Add crawfish: Gently fold in the cooked crawfish tails. Cook for 4–5 minutes, just to heat through. Don’t overcook.
  • Finishing touches: Add lemon juice, Parmesan (if using), and chopped parsley. Taste and adjust seasoning as needed.
  • Serve: Spoon over hot pasta, steamed rice, or toasted bread. Garnish with extra parsley and a lemon wedge if desired.

Notes

  • Use fresh or frozen crawfish: If fresh crawfish tails aren't available, frozen ones work well. Just ensure they are fully thawed and drained before cooking to prevent watering down the sauce.
  • Control the spice: Adjust the cayenne and Cajun seasoning based on your heat preference. For a milder version, use a low-sodium Cajun blend or omit the cayenne.
  • Don't overcook the crawfish: Crawfish is delicate and can become rubbery if overheated. Once added to the sauce, just warm them through for a few minutes.
  • Make ahead: The sauce can be prepared up to a day in advance (without the crawfish). Store in the refrigerator and reheat gently on the stove before adding crawfish and serving.
  • Serving suggestions: This creamy crawfish sauce pairs well with pasta (like linguine or fettuccine), white rice, or crusty bread. It’s also excellent over grits or mashed potatoes for a Southern twist.
  • Dairy-free variation: Substitute coconut cream or a plant-based alternative for the heavy cream, and skip the Parmesan. Add a splash of lemon juice for brightness.
  • Garnish for presentation: Fresh parsley and a squeeze of lemon just before serving add freshness and visual appeal, especially when plating for guests.
  • Storage: Leftovers keep well in an airtight container in the fridge for up to 2 days. Reheat slowly on the stovetop to preserve texture.
