Ingredients

  • Fettuccine (12 oz): Long, flat pasta perfect for soaking up the creamy Cajun sauce.
  • Shrimp (1 lb): Fresh peeled and deveined shrimp that provide tender, protein-packed bites.
  • Cajun seasoning (2 tbsp): A vibrant blend of spices that infuse shrimp with smoky, spicy flavor.
  • Olive oil (2 tbsp): Used for sautéing shrimp to develop a light crisp exterior.
  • Heavy cream (1 cup): Creates the rich, velvety sauce base for this pasta dish.
  • Grated Parmesan (1/2 cup): Adds a nutty, salty depth to the creamy sauce.
  • Green onions (1/4 cup, chopped): Fresh garnish that lends a mild oniony brightness.
  • Red pepper flakes (optional): For those who love extra heat, add just before serving.

Instructions

Toss the shrimp with Cajun seasoning

Coat the peeled and deveined shrimp evenly with the Cajun seasoning. This step ensures each shrimp is bursting with bold, spicy flavor before cooking.

Cook the fettuccine

Boil the pasta according to package instructions until al dente. Drain well but reserve some pasta water to adjust sauce consistency later if needed.

Sauté the seasoned shrimp

Heat olive oil in a large skillet over medium heat. Cook the shrimp until they turn pink and opaque, about 2-3 minutes per side. Remove and set aside to prevent overcooking.

Prepare the creamy Parmesan sauce

In the same skillet, add heavy cream and grated Parmesan cheese, stirring frequently until the sauce thickens slightly. This mixture delivers a luscious coating for the pasta.

Combine pasta, shrimp, and sauce

Toss the cooked pasta and shrimp into the creamy sauce. Use reserved pasta water to loosen the sauce if needed for a silky, balanced texture.

Garnish and serve

Sprinkle chopped green onions over the top for a fresh, zesty finish. Add red pepper flakes if extra spice is desired. Serve immediately while warm.

You Must Know

  • Use medium-sized shrimp for even cooking and balanced flavor.
  • Reserved pasta water contains starch that helps the sauce cling better to the noodles.
  • Adjust creaminess by adding pasta water gradually to avoid thinning too much.

Storage Tips

Store leftover Cajun Shrimp Pasta in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stove or microwave, adding a splash of cream or water to restore sauce creaminess.

Serving Suggestions

Serve with a crisp green salad or steamed vegetables to balance the richness of the pasta. A chilled glass of white wine such as Sauvignon Blanc pairs wonderfully with the dish. 

Professional Tips

  • For best flavor, toast Cajun seasoning briefly in the pan before tossing with shrimp.
  • Do not overcook shrimp; they cook quickly and become rubbery if left too long.
  • Use fresh Parmesan for better melting and deeper flavor in the sauce.

FAQs

Can I use other types of pasta?

Yes, linguine or penne work well as they catch the creamy sauce beautifully.

What if I don’t have heavy cream?

You can substitute with half-and-half, but the sauce will be less thick and creamy.

Can I prepare this dish ahead of time?

It’s best served fresh, but you can prepare shrimp and sauce separately, then combine when ready.

How spicy is this dish?

Moderately spicy from the Cajun seasoning; adjust heat by adding or omitting red pepper flakes.

Is this recipe gluten-free?

Not as is, but you can use gluten-free pasta to make it suitable for gluten-free diets.

Can I use frozen shrimp?

Yes, just thaw thoroughly and pat dry before seasoning and cooking.

What can I substitute for green onions?

Chives or fresh parsley can provide a similar fresh garnish alternative.
