Tips for the Best One-Pot Creamy Cajun Chicken Alfredo

Choose the Right Pasta

Fettuccine is classic, but penne and rigatoni also work well to hold the sauce.
For a quicker cooking option, use smaller pasta shapes like rotini.

Control the Heat Level

Adjust the amount of Cajun seasoning to suit your spice preference.
Add red pepper flakes for extra heat or use less Cajun seasoning for a milder dish.

Enhance the Flavor

A squeeze of lemon juice before serving brightens the dish and balances the richness.
Add smoked paprika for a deeper, smokier flavor.

Common Mistakes to Avoid When Making This Recipe

Stir occasionally while the pasta cooks to prevent sticking and ensure even cooking.

3. Adding Cheese Too Early

Add Parmesan at the end to avoid clumping or separating.
