Boil the pasta according to the package directions for al dente. Then drain it and set it aside, reserving ¼ cup of the pasta water.
Combine the Cajun seasoning, smoked sweet paprika, thyme, salt, and black pepper in a small bowl.
Coat both sides of the chicken evenly with the spice mixture.
Preheat the olive oil in a large skillet over medium heat. Then, sear the chicken for 4 to 5 minutes per side.
Flip the seared chicken once more, lower the heat to medium-low, cover the skillet with a lid, and continue cooking the chicken for 5 to 10 minutes until the internal temperature registers 165 degrees. Then, transfer it to a cutting board.
Alfredo Sauce
Melt the butter in the same pan, then add the minced onion, Cajun seasoning, oregano, basil, salt, and garlic pepper.
Simmer the onions and seasonings for about a minute until fragrant. Then, add the flour and stir well, scraping the bottom of the pan.
Add the heavy cream and chicken broth and whisk well. Then, cook, whisking continuously, until a thick, creamy sauce forms.
Add the mozzarella and parmesan cheese to the sauce and mix until completely melted. Continue cooking until the sauce reaches your desired consistency.
Add the pasta and toss well to coat it evenly. If necessary, thin the sauce with 1 tablespoon of pasta water at a time.
Slice the chicken breasts and add them on top of the pasta or mix them into the pasta. Enjoy!

Notes
Storage
Refrigerate for up to 3 days in an airtight container.
Freezing is not recommended for creamy sauces like this.
To reheat the pasta, cook it on medium-low in a saucepan until heated through or microwave it at 30-second intervals until heated through.
Tips
When rinsing chicken, hold it as close to the bottom of the sink as possible and use a gentle stream of water to avoid splashing as much as possible.
Wash the sink and counters immediately after rinsing the chicken.
You can rinse the pasta in cold water after cooking it to ensure it isn't overdone when added to the sauce.
