Kitchen Equipment
To make this casserole, you’ll need:
-
Large pot (for boiling pasta and cooking chicken)
-
Cutting board & sharp knife

Step-by-Step Directions
1. Preheat and Prep
Preheat your oven to 350°F (175°C). Lightly grease your casserole dish to prevent sticking and make cleanup easier.
2. Cook the Chicken
Heat a large pot over medium heat. Cook the chicken breasts for 6–7 minutes per side until golden brown and fully cooked. Remove from the pot and shred the chicken into bite-sized pieces.
Tip: You can save time by using a rotisserie chicken—just shred and skip this step.
3. Cook the Spaghetti
In the same pot, bring salted water to a boil. Cook spaghetti until al dente (about 8–10 minutes), drain well, and set aside.
4. Combine the Ingredients
In a large mixing bowl, combine shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the shredded cheddar cheese. Mix until everything is evenly coated.
5. Assemble the Casserole
Transfer the mixture to your greased casserole dish. Sprinkle the remaining cheese evenly on top for that irresistible golden crust.
6. Bake to Perfection
Bake for 25–30 minutes until the cheese is bubbly and golden brown.
7. Garnish and Serve
Let the casserole rest for 5 minutes before serving. Top with sliced green onions for a burst of color and freshness.
