A mouthwatering Blackened Cajun Chicken Alfredo blending fiery, well-rubbed chicken with smooth, velvety pasta. Every mouthful delivers perfectly seared blackened chicken on tender pasta, wrapped in a thick, garlicky Alfredo sauce - making an amazing comfort meal with a spicy twist.
The very first try making this changed our weekly family meals forever. The amazing way the Cajun heat plays with the rich sauce creates such a nice balance that my daughter, who usually avoids spicy food, wanted more.
Essential Ingredients
- Chicken Breasts: Flattened for even cooking
- Cajun Seasoning: Make your own or buy good quality
- Heavy Cream: Don't use reduced fat versions
- Parmesan Cheese: Grate it yourself only
- Fettuccine: Get good pasta for best results
- Unsalted Butter: Forms the sauce foundation
- Fresh Garlic: Chop right before using
- Fresh Parsley: Adds color on top
How To Make It
- 1. Get Chicken Ready:
- Flatten chicken breasts until they're about 1/4-inch thick. Cover completely with Cajun spices. Let them sit out for 10 minutes while you work on other stuff.
- 2. Boil The Pasta:
- Fill a big pot with water and bring it to a full boil. Add plenty of salt - the water should taste salty like the ocean. Cook your fettuccine until it's still a bit firm, about a minute less than what the box says. Save a cup of the cooking water before draining.
- 3. Cook The Chicken:
- Get a cast-iron pan super hot until it's smoking. Put in the chicken and cook for 3-4 minutes on each side until it gets that dark crust but isn't burnt. Check it reaches 165°F inside. Take it off and let it rest.
- 4. Whip Up The Sauce:
- Using that same pan, throw in butter and garlic, cooking until you can really smell it. Pour the heavy cream in and let it bubble gently. Slowly add Parmesan while stirring non-stop. Make it thinner with saved pasta water if needed.
- 5. Put It All Together:
- Cut the rested chicken into strips across the grain. Mix pasta with the sauce, adding some pasta water if it needs to be smoother. Top with the chicken slices, sprinkle with parsley, and add extra Parmesan.

When I learned to make this, I found out timing matters so much. My grandma from Italy always told me, "Pasta won't wait for anyone," and she wasn't kidding - getting everything ready before you start cooking means you'll get it right.
Keeping And Warming Up Leftovers
Keep any leftover chicken apart from pasta in sealed containers in your fridge for up to three days. The sauce will probably get much thicker when cold. When you warm it up, add a bit of cream or milk to make it creamy again. Always heat it slowly so the sauce stays smooth.

What To Serve With It
This hearty dish goes great with light sides like arugula with lemon dressing or cooked asparagus. Some garlic bread works wonders for mopping up extra sauce. If you want wine, go for a rich white like Chardonnay or a lighter red like Pinot Noir to match the creamy sauce.
Prepare Parts Ahead Of Time
You can get things ready separately for best results. Cook and slice the chicken ahead and keep it covered in the fridge. Make the Alfredo sauce and store it on its own. When you're ready to eat, warm the chicken in the oven, heat the sauce gently while cooking fresh pasta, then mix them all together. This way everything has the right texture.

This Blackened Cajun Chicken Alfredo brings together Southern heat and Italian comfort food perfectly. It's a hit for family dinners or when friends come over, always getting compliments for how the flavors and textures work together.
