Ingredient Notes

Step-by-Step Instructions
Step 1 – Prepare the Spaghetti and Chicken
Cook the spaghetti according to package instructions until al dente. Drain and set aside. Shred your cooked chicken and keep it ready.
Step 2 – Sauté Onion and Make Sauce
In a large skillet, melt butter over medium heat. Add the diced onion and sauté until translucent, about 3–4 minutes. Stir in seasoned salt, garlic powder, and black pepper.
Step 3 – Combine Sauce Ingredients
Add the cream of chicken soup, Velveeta cubes, milk, and drained Rotel tomatoes to the skillet. Stir continuously until the cheese is melted and the sauce is smooth.
Step 4 – Mix in Chicken and Spaghetti
Add the shredded chicken to the sauce and stir until fully coated. Fold in the cooked spaghetti, making sure the noodles are evenly covered with the cheesy sauce.
Step 5 – Assemble and Bake
Transfer the mixture to a greased 9×13-inch baking dish. Sprinkle shredded cheddar cheese on top. Cover with foil and bake at 350°F (175°C) for 20 minutes. Remove foil and bake for an additional 10 minutes until the cheese is bubbly and golden.
Step 6 – Serve
Allow the casserole to rest for 5 minutes before serving to let the flavors meld together.
