Cook pasta according to package directions until al dente. Drain and set aside.
In a skillet, heat olive oil over medium-high heat. Season chicken with Cajun spice, salt, and pepper.
Cook chicken until golden brown and cooked through, about 5 to 7 minutes.
Reduce heat to medium, pour in heavy cream, and let it bubble gently.
Stir in parmesan cheese until sauce thickens and coats the back of a spoon.
Add the cooked pasta into the skillet and toss until well coated with the sauce.
Serve hot with a sprinkle of fresh parsley if you’re feeling fancy.
