Cooking Directions

5. Toss cooked pasta into the sauce, adding reserved pasta water if needed.
6. Return shrimp to the skillet and combine.
7. Garnish with parsley and Parmesan. Serve immediately.

Step-by-Step Preparation Method

1. Boil the pasta – Salt the water well for flavor. Cook until just al dente.
2. Cook shrimp – Coat shrimp with Cajun seasoning, sear in butter and oil until golden and just cooked. Remove.
3. Make sauce – In the same pan, melt butter, sauté garlic, add cream and milk. Simmer gently.
4. Add cheese – Stir Parmesan into the sauce until melted and smooth.
5. Combine pasta – Toss pasta in sauce, add reserved water for creaminess.
6. Finish with shrimp – Return shrimp, mix well, and top with fresh parsley.
7. 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.

Special Equipment Needed

• Large skillet or sauté pan
• Pasta pot
• Wooden spoon or spatula
