Cheesy Chicken Spaghetti is a baked pasta casserole combining cooked spaghetti, shredded chicken, diced tomatoes, green chiles, and a creamy cheddar cheese sauce. The pasta is coated in a smooth cheese mixture flavored with sautéed onions, bell peppers, garlic, and milk-thickened roux, then baked with extra cheese topping for a bubbly, golden finish. This dish balances savory, mildly spicy elements with comfort-food richness.
