Cheesy Chicken Spaghetti

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.

Description

To make Cheesy Chicken Spaghetti, spaghetti is boiled and set aside while the sauce is prepared by sautéing diced onion and green bell pepper until softened, then adding garlic and flour to create a roux. Milk is whisked in and simmered until thickened, followed by stirring in cheddar cheese for a creamy sauce. Diced tomatoes and green chiles contribute acidity and mild heat, and shredded cooked chicken adds protein and texture. The cooked spaghetti is mixed into this sauce before transferring to a baking dish, topped with more cheddar cheese, and baked until bubbly and lightly browned.

The finished casserole combines tender pasta with a rich, cheesy sauce containing tender bits of chicken, tomatoes, and peppers, delivering a comforting and flavorful meal. Baking ensures a crisp, golden cheese crust while maintaining creaminess inside.

The recipe allows substitutions for cheddar with other cheeses such as Monterey Jack, mozzarella, pepper jack, or Mexican blends for varied flavors and textures. It is suited to dinner or hearty lunch, enjoyed fresh from the oven.
