How to Make Cajun Shrimp Alfredo

1. Cook the Pasta

Bring a large pot of salted water to a boil.

Add the fettuccine and cook according to the package directions until al dente.

Reserve about ½ cup of pasta water, then drain the pasta.

Set aside.

2. Season the Shrimp

Pat the shrimp dry with paper towels.

Place the shrimp in a bowl and toss with Cajun seasoning, smoked paprika, garlic powder, and black pepper.

3. Cook the Shrimp

Heat olive oil and butter in a large skillet over medium-high heat.

Add the shrimp in a single layer.

Cook for about 1–2 minutes per side, until the shrimp become opaque and are cooked through.

Transfer the shrimp to a plate.

Avoid overcooking them, as shrimp can quickly become tough.

4. Make the Garlic Alfredo Sauce

Reduce the skillet heat to medium-low.

Add the butter and let it melt.

Add the minced garlic and sauté for approximately 30–60 seconds, until fragrant.

Be careful not to brown or burn the garlic.

5. Add the Cream

Pour the heavy cream into the skillet.

Add Cajun seasoning and black pepper.

Bring the sauce to a gentle simmer and cook for 3–5 minutes.

Don't allow the cream to boil aggressively.

6. Add the Parmesan

Gradually add the freshly grated Parmesan while stirring continuously.

Continue stirring until the cheese melts and the sauce becomes smooth and creamy.

If the sauce is too thick, add a little reserved pasta water.

7. Add the Pasta

Add the cooked fettuccine to the Alfredo sauce.

Toss gently until the noodles are completely coated.

Add additional pasta water, one tablespoon at a time, if necessary.

8. Add the Cajun Shrimp

Return the cooked shrimp to the skillet.

Gently toss with the pasta and sauce for 1–2 minutes, just until heated through.

9. Finish and Serve

Add fresh lemon juice and chopped parsley.

Sprinkle with additional Parmesan cheese if desired.

Serve immediately while hot and creamy.

Pro Tips for the Best Cajun Shrimp Alfredo

Use large shrimp

Large or jumbo shrimp are ideal because they're easier to cook without becoming dry.

Pat shrimp dry

Removing excess moisture helps the shrimp sear rather than steam.

Don't overcook the shrimp

Shrimp cook quickly. Once they're opaque and cooked through, remove them from the skillet.

Use freshly grated Parmesan

Freshly grated Parmesan melts more smoothly and gives the Alfredo sauce a better texture.

Keep the sauce at a gentle simmer

High heat can cause a cream-based sauce to separate.

Reserve pasta water

The starchy water helps loosen the sauce and allows it to coat the pasta smoothly.

Taste before adding salt

Cajun seasoning and Parmesan can both be salty, so taste the sauce before adding additional salt.

What Pasta Is Best for Cajun Shrimp Alfredo?

Fettuccine is the classic choice because its wide noodles hold the creamy Alfredo sauce exceptionally well.

You can also use:

• Linguine
• Penne
• Rigatoni
• Rotini
• Spaghetti
• Bow-tie pasta

Penne and rigatoni are particularly good if you like lots of sauce in every bite.

How to Store Cajun Shrimp Alfredo

Allow leftovers to cool before placing them in an airtight container.

Refrigerate for up to 3 days.

When reheating, add a splash of milk, cream, or chicken broth to loosen the sauce.

Reheat gently until hot throughout.

Avoid repeatedly reheating the shrimp because they can become tough.

---

Can You Freeze Cajun Shrimp Alfredo?

You can freeze it, although cream-based Alfredo sauce may separate slightly after thawing.

For the best texture, prepare the pasta fresh.

If freezing leftovers, place them in an airtight freezer-safe container and freeze for up to 2 months.

Thaw overnight in the refrigerator and reheat gently with a little cream or milk.
