Step-by-Step Instructions for Making the Recipe
- Cook the Chicken: Preheat oven to 375°F (190°C). Drizzle chicken breasts with olive oil. Season with salt, pepper, garlic powder, and paprika. Bake for 20-25 minutes, or until cooked through. Shred or cube the chicken.
- Cook the Spaghetti: While the chicken is baking, cook the spaghetti according to package directions. Drain well.

- Make the Sauce: Stir in diced tomatoes and green chiles, cream of mushroom soup, cream cheese, chicken broth, chili powder, cumin, cayenne pepper (if using), and black pepper. Heat until a uniform color, mixing thoroughly. Simmer for 5 minutes, stirring to ensure cream cheese is fully melted.
