You can substitute the pasta, tone down the spice, or even swap in pre-cooked proteins if you’re short on time.

Ingredients and Substitutions

What You’ll Need

• 8 oz uncooked fettuccine
• 2 boneless skinless chicken breasts, cut into 1-inch cubes
• ½ pound raw shrimp (31/40 size), thawed and peeled
• ½ teaspoon garlic powder
• 1 tablespoon Cajun seasoning, divided
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 1 cup heavy cream
• 4 oz cream cheese, softened
• 2 cloves garlic, minced
• 1 cup freshly grated parmesan cheese
• Salt and pepper, to taste

Ingredient Tips

• Shrimp: Use medium-sized shrimp (31/40 count) for a good balance of bite and tenderness. Make sure they’re peeled and deveined.
• Chicken: Fresh chicken breasts cook quickly and stay juicy when seared properly.
• Parmesan: Always freshly grate your parmesan for smooth melting and better flavor.
• Cajun Seasoning: Choose a low- or no-salt blend to avoid an overly salty sauce.

Substitutions

• Pasta: Substitute with linguine, spaghetti, penne, or a gluten-free alternative.
• Cream Cheese: If unavailable, replace with mascarpone or reduce the cream and add extra parmesan for thickness.
• Protein Options: Use cooked rotisserie chicken or precooked shrimp for a shortcut. Add them at the end to warm through.

Step-by-Step Instructions

1: Prep Ingredients

• Take cream cheese out of the fridge at least 30 minutes before starting.
• Boil a large pot of salted water and cook fettuccine until al dente.
• If using frozen shrimp, thaw them under cold running water and pat dry.
• Cube chicken into bite-sized pieces.

2: Season the Protein

• In a bowl, toss shrimp and chicken with garlic powder and half the Cajun seasoning (½ tablespoon).

3: Cook the Shrimp

• Heat 1 tablespoon olive oil in a large skillet over medium-high heat.
• Add shrimp and cook for about 3 minutes total, flipping once. Remove and set aside.

4: Cook the Chicken

• Add the second tablespoon of oil to the skillet.
• Cook chicken pieces for 5 to 6 minutes until golden and fully cooked, stirring occasionally. Remove and set aside with shrimp.

5: Make the Alfredo Sauce

• Turn the heat to medium-low. Add butter, cream, cream cheese, remaining Cajun seasoning, and minced garlic to the skillet.
• Stir constantly until cream cheese fully melts and sauce is smooth and creamy.

6: Finish the Sauce

• Let the sauce bubble gently for 2 to 3 minutes until slightly thickened.
• Stir in parmesan cheese and mix well until melted.
• Add cooked shrimp and chicken back to the pan and stir to coat evenly.

7: Combine and Serve

• Drain the pasta and reserve a few tablespoons of pasta water.
• Add cooked fettuccine to the sauce. Toss everything together.
• If the sauce is too thick, add a splash of pasta water to loosen it.
• Taste and adjust seasoning with salt and pepper.
• Garnish with fresh parsley, extra parmesan, and a squeeze of lemon if desired.

Expert Cooking Tips

Best Techniques for Perfect Results

• Soften your cream cheese fully so it blends easily into the sauce.
• Use high heat to sear the proteins for the best texture and browning.
• Don’t overcook shrimp—just 1.5 minutes per side is usually enough.

Common Mistakes to Avoid

• Using salty Cajun seasoning can ruin the flavor balance. Stick to low-sodium.
• Adding parmesan too early or over high heat can make the sauce gritty.
• Cooking proteins together can cause steaming instead of browning. Cook separately for better texture.

Time-Saving Tricks

• Use pre-chopped garlic or a garlic press.
• Boil pasta while proteins are cooking to save time.
• Make the sauce ahead and refrigerate for up to 2 days (add proteins fresh when serving).

Serving Suggestions

What to Serve With Cajun Chicken and Shrimp Alfredo

• Garlic bread or cheesy toast for dipping
• A simple Caesar or arugula salad for contrast
• Steamed or roasted vegetables like broccoli or green beans

Beautiful Presentation Ideas

• Twirl pasta into nests on plates and top with shrimp and chicken.
• Sprinkle with finely chopped parsley or fresh chives.
• Serve in warm pasta bowls for better heat retention.

Drink Pairings

• Crisp white wines like Sauvignon Blanc or Pinot Grigio
• Sparkling lemonade or lemon-infused water
• Unsweetened iced tea with citrus

Storing and Reheating Leftovers

How to Store

• Store leftovers in an airtight container in the fridge for up to 3 days.
• Do not freeze—cream sauces tend to separate when thawed.

How to Reheat

• Reheat on the stovetop over low heat with a splash of cream or milk.
• Stir constantly to prevent the sauce from breaking.
• Microwave in short bursts at 50% power, stirring in between.
