A mouthwatering Blackened Cajun Chicken Alfredo combining fiery, well-rubbed chicken with smooth, velvety pasta. Every mouthful delivers perfectly seared blackened chicken on tender pasta, wrapped in a thick, buttery Alfredo sauce - making this the best cozy meal with a spicy twist.
When I first whipped this up, it completely changed our family's dinner routine. The amazing balance between the Cajun heat and creamy sauce worked so well that even my daughter who can't handle spicy food wanted more.
Essential Ingredients
- Chicken Breasts: Flattened for even cooking
- Cajun Seasoning: DIY or premium bought version
- Heavy Cream: Don't use low-fat options
- Parmesan Cheese: Only use freshly grated
- Fettuccine: Pick premium pasta brands
- Unsalted Butter: For starting the sauce
- Fresh Garlic: Chop right before cooking
- Fresh Parsley: To sprinkle on top
Easy Cooking Instructions
- 1. Get the Chicken Ready:
- First, pound your chicken breasts until they're about 1/4-inch thick. Cover them well with Cajun spice mix on all sides. Let them sit out for 10 minutes while you get everything else ready.
- 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 just firm, about a minute less than 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. Add the chicken and cook for 3-4 minutes on each side until it's dark but not burned. Make sure it reaches 165°F inside. Take it off the heat and let it rest.
- 4. Make the Sauce:
- Using the same pan, drop in butter and garlic, and cook until you can smell it. Add the heavy cream and let it bubble gently. Mix in Parmesan bit by bit, stirring all the time. Use some pasta water to thin it if needed.
- 5. Put It All Together:
- Cut the chicken across the grain after it's rested. Mix the pasta with the sauce, adding pasta water if it's too thick. Top with the chicken slices, some parsley, and extra Parmesan.

Making this dish taught me that getting the timing right matters a lot. My grandma from Italy always told me, "Pasta won't wait for anyone," and she wasn't kidding - having all your stuff ready before you start cooking really makes a difference.
Keeping and Warming Up
Keep any leftover chicken and pasta in different sealed containers in the fridge for up to three days. The sauce will get quite thick when cold. When you warm it up, add a little heavy cream or milk to make it creamy again. Always heat it slowly to keep the sauce from breaking apart.

What Goes Well With It
This hearty meal works great with light sides like arugula with lemon dressing or roasted asparagus. Grab some garlic bread to mop up the extra sauce. For drinks, go with a rich white wine like Chardonnay or a light red like Pinot Noir to match the creamy sauce.
Plan Ahead Options
It's best to fix different parts ahead of time. Blacken the chicken and slice it up early, then 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 boiling fresh pasta, then mix it 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 always a hit for family meals or when friends come over, thanks to its amazing combo of flavors and textures.
