Heat ½ tablespoon of olive oil in a 10-inch skillet on medium-high heat.
While the oil is heating, season the chicken pieces with ⅛ teaspoon of salt and the black pepper.
Place the chicken pieces in the skillet and brown or 1 to 2 minutes on each side. Then transfer to a bowl or plate. Pro Tip: The chicken does not have to be cooked through. The chicken pieces will continue to cook in the oven.
Add ½ tablespoon of olive oil to the pan and lower the heat to medium. Add the onions and cook until translucent, stirring frequently for about 2 minutes. Add the garlic and cook for an additional 30 seconds, stirring frequently.
Increase heat to medium-high and add mushrooms, cooking for 2 minutes with occasional stirring.
Pour in the chicken broth and stir.
Remove the skillet from the heat and stir in the sour cream, heavy cream, Italian seasoning, cheddar cheese, mozzarella cheese, and remaining ⅛ teaspoon of salt.
Add chicken and cooked spaghetti to the skillet, tossing to coat evenly.
Transfer the mixture to a greased 5x5-inch baking dish. Place the dish on a rimmed baking sheet to catch any spills.
Cover the casserole tightly with aluminum foil and bake for 20 to 25 minutes.
Remove from the oven, top with shredded or grated Parmesan cheese and fresh chopped parsley if desired, and enjoy hot.
