Creating Chicken Spaghetti is simple when you follow these straightforward steps:

1. Cook the Spaghetti: Begin by cooking the spaghetti according to package instructions. Drain and set aside.
2. Sauté Vegetables: In a large skillet, heat olive oil over medium heat. Add the chopped onion, bell pepper, and minced garlic. Sauté until the vegetables are softened, about 5 minutes.
3. Mix Ingredients: In the same skillet, add the shredded chicken, cream of mushroom soup, chicken broth, diced tomatoes, Italian seasoning, salt, and pepper. Stir to combine everything thoroughly.
4. Add Spaghetti: Gently fold the cooked spaghetti into the chicken mixture, ensuring it’s evenly coated with the sauce.
5. Add Cheese: Sprinkle half of the shredded cheddar cheese into the mixture, stirring until melted and well combined.
6. Transfer and Top: Pour the mixture into a greased baking dish. Top with the remaining cheddar cheese and spread it evenly over the top.
7. Bake: Preheat your oven to 350°F (175°C). Bake for 20-25 minutes, or until bubbly and golden on top.
8. Garnish: Remove from the oven and let it cool for a few minutes. Garnish with fresh parsley before serving.
9. Serve: Scoop servings onto plates, ensuring everyone gets a generous portion of chicken and cheese.

Following these steps will help you create a mouthwatering Chicken Spaghetti that everyone will love.
