Start by bringing a large pot of salted water to a boil. Add the linguine pasta and cook according to package instructions until al dente. Once cooked, reserve a bit of pasta water, then drain and keep the pasta warm.
In a medium bowl, combine the chicken strips with Cajun or Adobo seasoning, salt, basil, pepper, and garlic powder. Toss until the chicken is evenly coated in the spices.
In a large skillet, heat the oil over medium-high heat. Once hot, add the seasoned chicken strips. Cook for about 5-7 minutes, or until the chicken is golden and cooked through, stirring occasionally.
Reduce the heat to medium-low. Pour in the heavy whipping cream, stirring to combine with the chicken. Allow it to simmer gently for 2-3 minutes. Then, add in the shredded Parmesan cheese, stirring until melted and the sauce is creamy. If desired, add the optional smoked paprika for an extra layer of flavor.
Add the cooked linguine to the skillet with the Alfredo sauce, tossing to coat the pasta thoroughly. If the sauce is too thick, you can add a splash of the reserved pasta water to reach your desired consistency.
If you’re using sun-dried tomatoes, add them now, tossing gently to incorporate them into the pasta.
Serve the Cajun Chicken Alfredo hot, garnished with chopped green onions for a burst of freshness. Enjoy with crusty bread or a side salad for a complete meal!
