In a large cast iron skillet with a lid, (I used a porcelain cast iron pan) heat 2 tablespoons of olive oil over medium heat. Once the olive oil is warm, add in the tomatoes, dry shallots, and minced onion.
Allow this to cook for 5 to 7 minutes, until the tomatoes have been broken down, and are soft.
Give it a stir every two minutes while cooking. Next, add in the vodka sauce, water, Italian seasoning, salt, and roasted garlic powder.
Stir well, then add pasta.
Change the temperature to medium-high, and allow the mixture to begin to boil. Once it begins to boil, cover with the lid.
Stirring occasionally to keep it from sticking up the pan, cook until the pasta reaches an al dente texture, about 9-12 minutes depending on the pasta used.
Next, lower the heat to medium, remove the lid, and star in the heavy cream, cooked chicken, and mozzarella cheese.
Continue to stir until the cheese has melted all the way.
Lower the heat to low, and allow this to cook for an additional three minutes.Garnish with fresh basil.
Top with any extra fresh mozzarella or parmesan cheese.
