Spicy Southern Cheesy Chicken Spaghetti is a creamy, comforting dish loaded with tender shredded chicken, cheesy noodles, and a flavorful kick from Rotel tomatoes with green chilies. The recipe starts by sautéing onions in butter, then melting Velveeta cheese along with cream of chicken soup, Rotel tomatoes, and milk to create a rich, velvety sauce.
Seasoned salt, garlic powder, and black pepper add depth and a spicy touch. The cooked chicken and spaghetti are combined in the sauce and baked until bubbly, then topped with shredded cheddar for an extra cheesy finish.
This hearty casserole is perfect for weeknight dinners, serving 6-8, and leftovers reheat beautifully, making it a family favorite full of Southern charm and spice.
