Preheat your oven to 375°F (190°C). If planning to freeze, skip preheating.
Cook the spaghetti according to package directions until al dente. Drain and set aside.
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Sauté the mushrooms, onion, and garlic for 5-7 minutes, or until softened and fragrant. Remove from heat.
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute, stirring constantly.
Gradually add the chicken broth and milk to the saucepan, whisking to combine. Cook until the mixture thickens, about 5 minutes.
Stir in the cream cheese and Parmesan cheese until smooth. Season with salt and black pepper.
In a large mixing bowl, combine the cooked spaghetti, shredded chicken, sautéed vegetables, and cheese sauce. Mix until evenly coated.
Lightly coat a 9x13-inch baking dish with cooking spray. Transfer the pasta mixture into the dish and spread evenly.
Sprinkle the mozzarella cheese and breadcrumbs evenly over the top of the casserole.
If baking immediately, place in the preheated oven and bake for 25-30 minutes, or until golden and bubbling. Let stand for 5 minutes before serving.
For freezing: Cover the dish tightly with aluminum foil and label with the date. Freeze for up to 3 months. To bake from frozen, remove foil, cover with fresh foil, and bake at 375°F (190°C) for 50-60 minutes, removing the foil in the last 10 minutes to brown the top.
