Tools and Preparation

Having the right equipment helps ensure your Alfredo sauce stays creamy and your pasta cooks evenly.

Large Deep Skillet or Sauté Pan (12-inch / 30 cm)

A deep skillet allows the pasta to cook directly in the sauce while providing enough room for stirring without spills.

Sharp Chef’s Knife

Essential for cutting chicken into evenly sized pieces for consistent cooking.

Cutting Board

Provides a safe and stable surface for preparing ingredients.

Measuring Cups and Spoons

Accurate measurements help achieve the perfect sauce consistency.

Wooden Spoon or Silicone Spatula

Ideal for stirring the pasta and preventing the sauce from sticking to the pan.

Cheese Grater

Freshly grated Parmesan melts more smoothly than pre-shredded cheese and creates a silkier Alfredo sauce.

Ingredients List

For the Cajun Chicken

1 lb (450 g) boneless skinless chicken breast, diced
1 tablespoon (15 ml) olive oil
2 tablespoons (16 g) Cajun seasoning
½ teaspoon (3 g) kosher salt
¼ teaspoon (1 g) black pepper

For the Alfredo Pasta

8 oz (225 g) penne pasta
2 cups (480 ml) low-sodium chicken broth
1 cup (240 ml) heavy cream
3 cloves garlic, minced
1 tablespoon (14 g) unsalted butter
1 cup (100 g) freshly grated Parmesan cheese
½ teaspoon (1 g) paprika
¼ teaspoon (1 g) crushed red pepper flakes (optional)

For Garnish

2 tablespoons chopped fresh parsley
Extra Parmesan cheese
Fresh cracked black pepper

Step-by-Step Instructions

Step 1: Season the Chicken

In a bowl, combine the diced chicken with Cajun seasoning, salt, and black pepper. Toss until evenly coated.

Step 2: Sear the Chicken

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

Add the seasoned chicken and cook for 4–5 minutes, stirring occasionally, until lightly browned and nearly cooked through.

Transfer the chicken to a plate and set aside.

Step 3: Build the Flavor Base

Reduce heat to medium.

Add butter and minced garlic to the same skillet. Cook for about 30 seconds until fragrant, being careful not to burn the garlic.

Step 4: Add Pasta and Liquids

Pour in the chicken broth and heavy cream.

Stir in paprika and red pepper flakes if using.

Add the uncooked penne pasta and stir well.

Step 5: Cook the Pasta

Bring the mixture to a gentle boil.

Reduce heat to medium-low, cover, and simmer for 10–12 minutes.

Stir every few minutes to prevent sticking and ensure even cooking.

Cook until the pasta is tender and most of the liquid has been absorbed.

Step 6: Finish the Alfredo Sauce

Reduce heat to low.

Gradually stir in the Parmesan cheese until fully melted and smooth.

The sauce should become thick, creamy, and luxurious.

Step 7: Return the Chicken

Add the cooked chicken back to the skillet.

Stir gently to coat every piece in the Alfredo sauce.

Cook for another 2–3 minutes until everything is heated through.

Step 8: Garnish and Serve

Top with chopped parsley, additional Parmesan cheese, and freshly cracked black pepper.

Serve immediately while hot and creamy.

Chef’s Tips & Common Mistakes to Avoid

Chef’s Tips

Use Fresh Parmesan

Freshly grated Parmesan melts smoothly and creates a superior Alfredo sauce.

Don’t Overcook the Chicken

Chicken continues cooking when returned to the skillet. Slightly undercook it during the searing stage.

Adjust the Heat Level

Love spice? Add extra Cajun seasoning or red pepper flakes.

Prefer milder flavors? Reduce Cajun seasoning to 1 tablespoon.

Let the Sauce Rest

Allow the skillet to sit for 2–3 minutes before serving. The sauce thickens beautifully during this time.

Reserve Extra Broth

If the pasta absorbs too much liquid, stir in a splash of warm chicken broth to loosen the sauce.

Common Mistakes to Avoid

❌ Boiling the cream aggressively

High heat can cause the sauce to separate.

❌ Adding Parmesan too quickly

Add cheese gradually for the smoothest texture.

❌ Using pre-shredded cheese

Anti-caking agents often prevent smooth melting.

❌ Forgetting to stir the pasta

Pasta cooked in one pot needs occasional stirring to prevent sticking.

❌ Overcrowding the skillet

Use a large skillet so ingredients cook evenly.
