Boil a large pot of salted water. Add spaghetti and cook until tender but still firm. Drain the pasta well and set it aside. Do not overcook it because it will bake later in the oven with sauce and chicken mixture.

Use cooked chicken and shred it into small pieces. You can use leftover chicken or rotisserie chicken. Make sure the pieces are soft and easy to mix. This helps the chicken blend well with the creamy sauce later in the recipe.

Heat olive oil in a pan over medium heat. Add onions, bell pepper, and garlic. Cook until soft and fragrant. Stir often to avoid burning. This step builds flavor and gives the dish a rich homemade taste base.

In a bowl, mix cream of chicken soup, cream of mushroom soup, and chicken broth. Stir until smooth and creamy. Add salt, pepper, and paprika. This sauce is the heart of the Ingredients for Pioneer Woman Chicken Spaghetti Recipe.

Add cooked spaghetti, shredded chicken, cooked vegetables, and diced tomatoes into a large bowl. Pour the creamy sauce over everything. Mix gently until all ingredients are fully coated with the sauce and well combined.

Stir in half of the shredded cheddar cheese. Mix well so it melts slightly into the warm mixture. Then transfer everything into a greased baking dish. Spread it evenly so it bakes properly and cooks at the same rate.

Preheat oven to 350°F (175°C). Bake the dish for 20–25 minutes. Sprinkle remaining cheese on top halfway through baking. Wait until the top becomes bubbly, golden, and slightly crispy for the perfect comforting finish.
