Cook the pasta in a large pot of salted boiling water according to package instructions until al dente. Drain and set aside.
While the pasta cooks, season the chicken strips generously with Cajun seasoning, salt, and pepper.
Heat olive oil in a large skillet over medium-high heat, then add the seasoned chicken. Sear until golden brown and cooked through, about 5-7 minutes. Remove the chicken from the pan and set aside.
Add minced garlic to the same skillet and sauté for about 30 seconds, until fragrant and slightly soften, with a gentle bubbling sound.
Pour in the chicken broth and heavy cream, stirring with a spatula or spoon to scrape up browned bits from the bottom of the pan. Bring the mixture to a gentle simmer and cook for 5 minutes, allowing the sauce to thicken and become silky.
Return cooked chicken to the skillet, stirring to coat it evenly with the sauce. Add a sprinkle of paprika for extra flavor and color.
Gently fold in the cooked pasta, mixing everything together so the sauce clings to the noodles and chicken, creating a creamy, cohesive dish. Warm through for a couple of minutes.
Taste the dish and adjust salt and pepper as needed for flavor. The sauce should be smooth and velvety, coating all ingredients evenly.
Serve hot, garnished with chopped herbs if desired. Enjoy this creamy Cajun chicken pasta with a side of crusty bread or a fresh green salad.
