Preheat oven to 375°F. Lightly grease a 9x13-inch baking dish.
Cook spaghetti in salted boiling water for 2 minutes less than package directions. Drain and set aside.
Toss chicken pieces with Cajun seasoning, garlic powder, and black pepper.
Heat olive oil in a large skillet over medium-high heat. Add chicken in a single layer, working in batches if needed. Cook for 5–7 minutes, stirring occasionally, until browned and cooked through to 165°F. Remove and set aside.
Reduce heat to medium. Add butter, onion, and bell pepper to the same skillet. Cook for 4–5 minutes until softened. Add garlic and cook another 30 seconds.
Stir in Rotel, cream of chicken soup, chicken broth, cream cheese, and smoked paprika. Cook for 3–4 minutes, stirring until smooth and creamy.
Reduce heat to low. Stir in 1 cup cheddar and ½ cup Monterey Jack until melted. Taste and adjust seasoning.
Add cooked chicken and spaghetti to the sauce. Toss until everything is evenly coated. Add a splash of chicken broth if needed to loosen the sauce.
Transfer to the prepared baking dish. Top with remaining 1 cup cheddar.
Bake uncovered for 15–20 minutes until hot, bubbly, and melted. For a golden finish, broil for 1–2 minutes, watching closely.
Let rest for 5 minutes. Garnish with parsley or green onions and serve.
