This simple Lemon Pepper Cajun Chicken Fettuccine Alfredo is a favorite with everyone. Classic, creamy fettuccini Alfredo with butter, garlic, and plenty of parmesan. Then topped with crispy lemon pepper cajun chicken. Every twirl of pasta melts in your mouth and the chicken adds a nice buttery, spiciness to every bite. It’s delicious.

Sometimes you have those recipes that you just know you’re going to love. I feel like this fettuccine will be that recipe for many of you. Creamy Alfredo pasta mixed with spicy, buttery cajun chicken, it’s a combo we all can love. 

Simple, but wow, so good, and the chicken really does add so much flavor. What I said above really stands true, everyone loves this dish.

The inspiration 

Growing up my dad often made fettuccini alfredo on Friday or Saturday night. It was always a special night when he made it because he didn’t make it that often. Or well, just not as often as he made say tacos. My dad has made a lot of tacos. 

I loved alfredo night, it always felt so fancy to me. Looking back I didn’t realize just how simple it was, especially my dad’s Alfredo. He kept his basic with lots of butter, cream, and parmesan. He also added cream cheese, which made it extra rich. 

I wanted to see if I could improve on his old skool, classic pasta. We love anything involving a little cajun seasoning around here, so adding in some cajun chicken sounded perfect.

The steps 

Before starting the chicken boil off the pasta. 

Next, toss the chicken in olive oil, homemade cajun seasoning (my recipe is in the notes), parmesan, and a big pinch of pepper. 

Sear up the chicken in a skillet with some butter until it becomes deeply golden and crisp. Then pour over some lemon juice and let it sizzle around the chicken.

Nothing fancy, but the smells coming from your skillet sure will be delicious. 

Now onto the pasta, this happens really quickly.

Use the same skillet you cooked the chicken in so you get all that yummy flavor. Add in a bit more butter and some garlic. Then pour in broth and milk (you can also use cream). I like to use broth and milk to create a still creamy pasta, but a pasta that has a nice amount of sauciness to it as well. It’s also a little lighter than using all cream or milk, so the alfredo isn’t quite as rich. 

Once the sauce has thickened, stir in the parmesan and pasta. I like to use linguine, but fettuccini is obviously great too.

And that’s it! Serve the chicken over steaming bowls of creamy pasta and top with additional parmesan and fresh parsley. Yummmm!

This recipe is all about the creamy sauce and that crispy cajun chicken. The sauce is buttery, a touch garlicky, and so creamy. And the crispy chicken…it’s a game-changer. Tender and delicious when thinly sliced and tossed in with the pasta.

It’s one of those chicken pasta dinners that feels like a dish you’d order at a restaurant. But it’s made at home and is even more delicious. Trust me.

  1. Teighan!!

    I am Cajun and from south Louisiana, I tried this recipe a few days ago— and this seriously is one of the best Cajun dishes I’ve ever had. Thank you for sharing your gifts with the world!

    1. Wow, thank you so much, Bridget!! Love to hear that this recipe was a hit and I appreciate you making it! xT

  2. Can you help me understand when I should or should not use my cast iron? Like I have one because my grandma and everyone swears by it but I don’t understand when I should or shouldn’t use it. Is this recipe a cast iron? Like I think yes until we get to the acid and then I am like maybe not. Please help.

    1. Hey Kellsey,
      I pretty much always cook in cast iron:) I use Staub products which are enamel coated so I never have issues using acid in them. I hope this helps! xT

      1. Doesn’t that ruin the point of cast iron? I thought the point was to have the seasoning (unwashed with detergent) in the iron. Just trying to understand because what I end up doing is washing my cast iron with detergent and never using it. Only using my like green pans which I don’t love but I have them.

    I’m not sure how I missed this recipe a few years ago when it came out. I made it tonight and it was the biggest hit with the family. I initially thought I would use a premade Cajun seasoning that is a staple in our house. On a second thought, I mixed up your Cajun seasoning recipe. It was the bomb! The whole dish was so delicious and full of flavor! It will go in our supper rotation. Thank you for making these wonderful recipes!

    I enjoyed the flavors just fine, but the recipe on the whole was a bit lacking. I might try adding some veggies if I make it again. Frozen peas? Broccoli? I’d say peppers but then my kids wouldn’t eat it. 😉
