Creating Monterey Chicken Spaghetti can be both fun and simple. Follow these step-by-step instructions to make this amazing dish:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Sauté Vegetables: In a large skillet, heat the olive oil over medium heat. Add the diced onion and bell pepper, cooking until softened, about 5-7 minutes. Stir in the minced garlic and cook for another minute until fragrant.
3. Combine Ingredients: In a large mixing bowl, combine the cooked spaghetti, shredded chicken, sautéed vegetables, Italian seasoning, paprika, chicken broth, heavy cream, salt, and pepper. Mix until everything is evenly coated.
4. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish.
5. Add Cheese: Sprinkle the shredded Monterey Jack cheese evenly over the top of the spaghetti mixture. If using breadcrumbs, sprinkle them over the cheese for added crunch.
6. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the cheese is melted and bubbly.
7. Garnish and Serve: Once done, remove from the oven and let it cool for a few minutes. Garnish with fresh parsley if desired, and serve warm.
