Method
 

Preparation
  1. Preheat your oven to 350°F (175°C) and grease a large casserole dish.
  2. Cook the chicken in a large pot over medium heat for about 6–7 minutes per side until golden and cooked through.
  3. Boil salted water and cook spaghetti until al dente (about 8–10 minutes), then drain and set aside.
  4. In a bowl, mix the shredded chicken, cooked spaghetti, cream of chicken soup, bell peppers, spices, and half of the cheddar cheese until well combined.
Baking
  1. Transfer the mixture to the greased casserole dish and top with the remaining cheese.
  2. Bake for 25–30 minutes until bubbly and golden brown.
  3. Let it rest for 5 minutes before garnishing with chopped green onions and serving.
