Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish or two smaller freezer-safe pans if dividing.
Bring a large pot of salted water to a boil and cook the spaghetti according to package instructions until al dente. Drain and set aside.
In a large skillet, melt the butter over medium heat. Add the diced onion and cook until softened, about 3-4 minutes.
Stir in the minced garlic and sliced mushrooms. Cook until the mushrooms release their liquid and are tender, about 5-6 minutes.
Sprinkle the flour over the mushroom mixture and stir constantly for 1-2 minutes to cook out the raw flour taste.
Gradually whisk in the chicken broth and heavy cream, making sure to eliminate any lumps. Bring the mixture to a simmer and cook for a few minutes until it thickens.
Stir in the softened cream cheese, grated Parmesan, salt, and black pepper. Continue stirring until the sauce is smooth and creamy.
Add the cooked chicken and peas (if using) into the sauce, then remove from heat.
In a large mixing bowl, combine the cooked spaghetti and the sauce, mixing well to ensure even coating.
Transfer the mixture into the prepared baking dish or pans, spreading evenly.
In a small bowl, mix the breadcrumbs with olive oil. Sprinkle evenly over the top of the pasta mixture.
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the dish is bubbly.
If freezing, allow the uncooked dish to cool completely. Wrap tightly in plastic wrap and aluminum foil before placing in the freezer for up to 3 months.
To bake from frozen, remove wrapping and bake at 350°F (175°C) for 60-75 minutes, or until heated through and bubbling.
