Ingredients
For the Chicken
1 tablespoon olive oil
1 pound chicken breast, diced into 1-inch cubes
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon Cajun seasoning
For the Pasta
12 ounces penne pasta
For the Alfredo Sauce
2 tablespoons salted butter

1 tablespoon all-purpose flour
½ teaspoon salt
1 teaspoon Cajun seasoning
2 cups heavy whipping cream
1 cup freshly grated Parmesan cheese

½ cup diced tomatoes

How to Make Cajun Chicken Alfredo Pasta
1. Cook the Chicken
Heat the olive oil in a large skillet over medium heat.
Season the diced chicken with salt, black pepper, and Cajun seasoning. Add the chicken to the skillet and cook for about 6–8 minutes, stirring occasionally, until golden brown and cooked through.
Remove the chicken from the skillet and set aside.
2. Cook the Pasta
While the chicken cooks, bring a large pot of salted water to a boil.
Cook the penne according to the package directions, usually about 10 minutes, until al dente. Drain and set aside.
3. Make the Alfredo Sauce
Return the skillet to medium-low heat. Add the butter and allow it to melt.
Add the minced garlic and cook for about 1 minute, stirring frequently, until fragrant.
Sprinkle in the flour, salt, and Cajun seasoning. Whisk continuously for about 1 minute, until the flour and butter form a smooth paste.
4. Add the Cream
Slowly pour in the heavy cream while whisking constantly to prevent lumps from forming.
Allow the sauce to gently simmer for 3–4 minutes, whisking frequently. Do not let the sauce come to a boil.
5. Add the Parmesan
Stir in the freshly grated Parmesan cheese and remove the skillet from the heat.
Continue stirring until the Parmesan has completely melted and the sauce is smooth and creamy.
6. Combine Everything
Add the cooked chicken and drained penne to the Alfredo sauce.
Toss gently until the pasta and chicken are evenly coated in the sauce.
7. Garnish and Serve
Top with diced tomatoes and fresh parsley.
Serve immediately while the pasta is hot and the Alfredo sauce is creamy.
Why This Recipe Works
This Cajun Chicken Alfredo strikes the perfect balance between creamy comfort food and bold flavor. The Cajun seasoning adds smoky depth without overpowering the rich Alfredo sauce, while the fresh tomatoes and parsley help brighten the dish and balance the richness.
Using freshly grated Parmesan also helps create a smoother, creamier sauce compared to pre-shredded Parmesan.
Tips for the Best Cajun Chicken Alfredo
Use freshly grated Parmesan for the smoothest, creamiest sauce.
Keep the Alfredo sauce at a gentle simmer and avoid boiling it, which can cause the sauce to separate.
Cook the pasta just to al dente so it doesn't become too soft when tossed with the sauce.
Adjust the Cajun seasoning to your preferred level of spice.
Dice the chicken into evenly sized pieces so everything cooks at the same rate.
Add the tomatoes and parsley just before serving for the freshest flavor.
If the sauce becomes too thick, add a small splash of reserved pasta water or cream to loosen it.
What to Serve with Cajun Chicken Alfredo
This creamy pasta pairs perfectly with:
Garlic bread
Caesar salad
Roasted broccoli
Side salad
Breadsticks
Steamed vegetables
A simple green salad or roasted vegetable is especially good alongside the rich Alfredo sauce.
Storage Instructions
Store leftover Cajun Chicken Alfredo in an airtight container in the refrigerator for up to 3 days.
Reheat gently over low heat on the stovetop or in the microwave. Add a splash of cream or milk while reheating if the sauce has thickened.
Frequently Asked Questions
Is Cajun Chicken Alfredo spicy?
This recipe has mild heat from the Cajun seasoning but isn't overly spicy. If you prefer more heat, you can add additional Cajun seasoning or a pinch of cayenne pepper.
Can I use a different pasta?
Absolutely! Fettuccine, rigatoni, rotini, bowtie pasta, or even spaghetti can be used in place of penne.
Can I use pre-shredded Parmesan?
You can, but freshly grated Parmesan is recommended. It melts more smoothly and creates a creamier Alfredo sauce.
Can I make Cajun Chicken Alfredo ahead of time?
Yes, but Alfredo sauce is best when served fresh. If you need to reheat leftovers, add a splash of cream or milk and warm them gently to help bring the sauce back to a creamy consistency.
Can I add vegetables to Cajun Chicken Alfredo?
Definitely. Broccoli, spinach, bell peppers, mushrooms, or asparagus would all work well in this pasta.
