🛒 Ingredients

For the Shrimp

• 1 lb large shrimp, peeled and deveined
• 1 ½ tablespoons Cajun seasoning
• 1 tablespoon olive oil
• 1 tablespoon unsalted butter
• 3 cloves garlic, minced
• ½ teaspoon smoked paprika
• ¼ teaspoon black pepper
• 1 tablespoon lemon juice

For the Alfredo

• 12 oz fettuccine pasta
• 3 tablespoons unsalted butter
• 4 cloves garlic, minced
• 1 ½ cups heavy cream
• 1 cup freshly grated Parmesan cheese
• ½ cup reserved pasta water
• ½ teaspoon Cajun seasoning
• ¼ teaspoon black pepper
• ¼ teaspoon red pepper flakes, optional
• Salt, to taste

For Garnishing

• 2 tablespoons chopped fresh parsley
• Extra Parmesan cheese
• Pinch of Cajun seasoning
• Lemon wedges, optional

👩‍🍳 Instructions

1. Cook the Pasta

Bring a large pot of salted water to a boil.

Cook the fettuccine according to the package directions until al dente.

Before draining, reserve about ½ cup of pasta water.

Drain the pasta and set aside.

2. Season the Shrimp

Pat the shrimp dry with paper towels.

Place them in a bowl and toss with Cajun seasoning, smoked paprika, black pepper, and lemon juice.

Make sure the shrimp are evenly coated.

3. Cook the Shrimp

Heat olive oil and 1 tablespoon butter in a large skillet over medium-high heat.

Add the shrimp in a single layer.

Cook for about 2 minutes per side, or until the shrimp are pink, opaque, and lightly browned.

Add the minced garlic during the final 30 seconds and stir until fragrant.

Remove the shrimp from the skillet and set aside.

4. Make the Alfredo Sauce

Reduce the heat to medium.

Add 3 tablespoons butter to the same skillet.

Once melted, add the minced garlic and cook for about 30 seconds.

Pour in the heavy cream and stir well.

Add Cajun seasoning, black pepper, and red pepper flakes if using.

Bring the sauce to a gentle simmer for about 2–3 minutes.

5. Add the Parmesan

Reduce the heat to low.

Gradually add the freshly grated Parmesan cheese, stirring continuously until melted and smooth.

If the sauce is too thick, add a little reserved pasta water at a time until you reach a silky consistency.

6. Combine the Pasta

Add the cooked fettuccine directly to the Alfredo sauce.

Toss gently until every strand is coated.

If needed, add another splash of pasta water to loosen the sauce.

7. Add the Shrimp

Return the Cajun shrimp to the skillet.

Gently toss everything together and cook for 1–2 minutes, just until the shrimp are heated through.

Taste and adjust the Cajun seasoning, salt, and pepper.

8. Garnish and Serve

Remove from the heat.

Top with fresh parsley and plenty of grated Parmesan.

Add a small sprinkle of Cajun seasoning and serve immediately with lemon wedges if desired.

🔥 Tips for the Best Cajun Shrimp Alfredo

Don’t overcook the shrimp: Shrimp cook quickly. Remove them as soon as they’re opaque and pink to keep them tender.

Use freshly grated Parmesan: It melts much more smoothly into the cream sauce.

Save the pasta water: The starchy water helps loosen and emulsify the Alfredo sauce.

Watch the heat: Keep the Alfredo sauce at a gentle simmer rather than a rolling boil.

Adjust the Cajun seasoning: Different Cajun seasoning blends have different salt and spice levels, so taste before adding extra salt.

🌶️ Easy Variations

Extra Spicy Cajun Alfredo

Add more Cajun seasoning, red pepper flakes, or a pinch of cayenne.

Cajun Chicken & Shrimp Alfredo

Add sliced cooked chicken along with the shrimp for an extra-hearty dinner.

Cajun Sausage Alfredo

Add sliced smoked sausage or andouille sausage for a smoky, filling variation.

Spinach Cajun Alfredo

Stir in 2 cups of fresh spinach during the final few minutes of cooking.

Cajun Shrimp Broccoli Alfredo

Add steamed broccoli for extra vegetables and texture.

Blackened Shrimp Alfredo

Coat the shrimp generously with Cajun seasoning and sear them over higher heat for a darker, more intensely seasoned crust.

🥖 What to Serve With Cajun Shrimp Alfredo

This creamy pasta pairs beautifully with:

• Garlic bread
• Cheesy breadsticks
• Caesar salad
• Roasted broccoli
• Garlic green beans
• Simple garden salad
• Sautéed spinach
• Crusty French bread

🧊 Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days.

Alfredo sauce thickens as it cools, so add a splash of milk, cream, or chicken broth when reheating.

Reheat gently in a skillet over low to medium-low heat, stirring occasionally until hot.

Avoid overheating the shrimp, as they can become rubbery.
