Creating Cheesy Cajun Garlic Chicken Rotini Skillet is simple if you follow these steps:

1. Cook the Pasta: In a large pot, boil salted water and cook the rotini according to package instructions until al dente. Drain and set aside.
2. Season the Chicken: In a bowl, toss the diced chicken with Cajun seasoning, salt, and black pepper until evenly coated.
3. Sauté the Chicken: Heat olive oil in a large skillet over medium heat. Add the seasoned chicken and cook until browned and cooked through, about 6-8 minutes. Remove the chicken from the skillet and set aside.
4. Sauté Garlic: In the same skillet, add minced garlic and sauté for 1-2 minutes until fragrant, being careful not to burn it.
5. Make the Sauce: Pour in the heavy cream and bring to a simmer. Stir continuously until the cream thickens slightly, about 2-3 minutes.
6. Add Cheese: Lower the heat and mix in the cheddar and mozzarella cheeses. Stir until melted and combined.
7. Combine: Return the cooked chicken to the skillet and add the drained rotini. Toss everything together until well coated in the creamy sauce.
8. Adjust Seasoning: Taste and adjust seasoning as needed. Feel free to add more Cajun seasoning for an extra kick.
