Ingredients
- Boneless skinless chicken breasts: add protein and soak up flavor well try to choose ones that are even in thickness for even cooking
- Cajun seasoning: gives that signature heat and depth check labels for quality spices without fillers or make your own for the freshest flavor
- Fettuccine pasta: holds the creamy Alfredo beautifully look for bronze cut if possible for better sauce grip
- Butter: creates a rich flavor base opt for European butter for a silkier finish
- Heavy cream: makes the sauce extra luscious use fresh cream for the smoothest texture
- Minced garlic: brings aromatic sweetness crush your own cloves right before cooking
- Grated Parmesan cheese: adds salty depth freshly grated melts best and enriches the sauce
- Salt and pepper: highlight all the flavors use kosher salt and freshly cracked pepper for balance
Step-by-Step Instructions
- Season the Chicken:
- Rub Cajun seasoning all over the chicken breasts making sure to coat both sides evenly so every bite has flavor
- Cook the Chicken:
- Place chicken in a skillet over medium heat and cook for about six minutes per side until golden brown and juices run clear then let the chicken rest so it stays juicy
- Make the Sauce:
- In the same pan melt butter over medium low heat add minced garlic and sauté for one minute for that fragrant base
- Simmer the Cream:
- Pour in heavy cream and let it gently bubble for two to three minutes to develop thickness without boiling
- Add Cheese and Season:
- Gradually sprinkle in Parmesan cheese whisking constantly until the sauce becomes smooth and coats the back of a spoon finish by seasoning with salt and pepper to taste
- Cook the Pasta:
- Boil fettuccine in salted water until just al dente then drain making sure to save a cup of the cooking water to adjust the sauce if needed
- Combine Chicken Pasta and Sauce:
- Slice the cooked chicken and add it back to the skillet with the Alfredo sauce along with the cooked pasta toss until everything is well coated and add a splash of reserved pasta water if the sauce feels too thick

Parmesan brings so much umami and silkiness to the sauce it is my secret to making this dish feel special each time I serve it family gathers round the table and we always end up with empty plates
Storage Tips
Leftovers keep well for two days in an airtight container in the fridge the sauce will thicken as it cools so I like to add a splash of milk or cream before reheating to bring back its luscious texture Microwaving gently in short bursts works best to keep everything creamy and tender
Ingredient Substitutions
If you want to lighten it up swap half the cream for whole milk or even use cooked shrimp in place of chicken For extra vegetables toss in some spinach or sautéed bell peppers with the sauce Freshly grated Romano cheese can replace Parmesan for a sharper bite
Serving Suggestions
This pasta shines on its own but a crisp green salad or garlic bread makes a perfect side Dish it up hot with a sprinkle of extra Cajun seasoning or chopped parsley A simple squeeze of lemon over the top lifts all the flavors and balances the richness
