Cooking Directions
- Cook pasta in salted boiling water until al dente. Reserve ½ cup pasta water, then drain.
- Season shrimp with Cajun seasoning. Heat olive oil and butter in a skillet, cook shrimp for 2–3 minutes per side until pink and opaque. Remove and set aside.

- Return shrimp to the skillet and combine.
- Garnish with parsley and Parmesan. Serve immediately.
Step-by-Step Preparation Method
- Boil the pasta – Salt the water well for flavor. Cook until just al dente.
- Cook shrimp – Coat shrimp with Cajun seasoning, sear in butter and oil until golden and just cooked. Remove.
- Make sauce – In the same pan, melt butter, sauté garlic, add cream and milk. Simmer gently.
- Add cheese – Stir Parmesan into the sauce until melted and smooth.
- Combine pasta – Toss pasta in sauce, add reserved water for creaminess.
- Finish with shrimp – Return shrimp, mix well, and top with fresh parsley.
- Serve hot – With garlic bread or a side salad.
How to Serve
- Serve as a main dish with garlic bread and a crisp green salad.
- Pair with white wine such as Chardonnay or Sauvignon Blanc.
- Garnish with fresh herbs and lemon wedges for brightness.
Recipe Tips
- Don’t overcook the shrimp—they cook very quickly.
- Use freshly grated Parmesan for the smoothest sauce.
- Adjust Cajun seasoning depending on your spice tolerance.
- Save pasta water—it helps emulsify and thicken the sauce.
Variations
- Chicken Cajun Pasta – Replace shrimp with chicken breast strips.
- Andouille Cajun Pasta – Add sliced Cajun sausage for a smoky kick.
- Vegetarian Option – Use mushrooms, zucchini, or bell peppers instead of shrimp.
- Spicy Cream Sauce – Add crushed red pepper flakes or hot sauce.
- Lightened-Up Version – Use half-and-half instead of heavy cream.
Freezing and Storage
- Refrigeration: Store in an airtight container for up to 3 days.
- Freezing: Not ideal (cream sauces can separate), but shrimp and pasta can be frozen separately for up to 2 months.
- Reheating: Reheat gently in a skillet with a splash of milk or cream to bring sauce back together.
