Preheat and prep: Heat the oven to 400°F. Grease or spray with cooking spray a 9x14 baking dish.
Combine the Ingredients: Add the chicken, tortellini, broth, salt, garlic, and veggies to the prepared baking dish, stirring to combine. Nestle the Boursin cheese into the middle. Do not stir.
Cover & Bake: Cover tightly with foil. Bake for 30 minutes.
Top with Cheese: Uncover and stir to combine the Boursin cheese until well combined. Top with the shredded Italian cheese blend. Lightly tent with foil and bake for 5-10 minutes, or until the cheese has melted and just browned on top.
Allow to Sit: Remove from the oven and allow to sit for 5-10 minutes lightly tented with the foil for the tortellini to absorb a bit more sauce. Serve with remaining sauce drizzled over the top.
