Notes before you begin
Use cooked, shredded chicken that you trust—rotisserie chicken, leftover baked chicken, or poached chicken all work perfectly. The spaghetti must be cooked al dente and drained well so the casserole doesn’t become watery. The Velveeta and cream cheese are cubed to allow faster, even melting. If you prefer a little more tang, swap half a cup of the cream of chicken soup for plain Greek yogurt, but the ingredient list below remains the source of truth for quantities in the final directions.
Rewritten step-by-step directions
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish or a similar-sized casserole pan and set it aside.
- Bring a large pot of salted water to a boil. Add 8oz spaghetti and cook until just al dente according to package instructions. Drain the pasta thoroughly in a colander and return it to the pot or place it in a large mixing bowl.
- While the pasta cooks, cube 8oz Velveeta and 4oz cream cheese so they melt evenly later. Open the 14.5oz can of Rotel tomatoes and drain a small amount of excess liquid if it seems very watery; reserve the tomatoes and juices together if you prefer a saucier bake.
- To the drained spaghetti, add 1 cup shredded chicken and 1 tablespoon minced garlic. Toss gently to combine so the garlic distributes through the pasta and warms slightly from the residual heat.
- Add the cubed Velveeta and cubed cream cheese to the pasta and chicken mixture. Stir in 10.5oz cream of chicken soup and the 14.5oz Rotel tomatoes. Mix until the cheeses begin to soften and the soup and tomatoes coat the pasta evenly. The warmth from the pasta will help the cheeses break down; use a spoon or spatula to press and blend any remaining chunks.
- Sprinkle 1 tablespoon Italian seasoning into the mixture. Fold everything together gently but thoroughly, ensuring the seasoning, tomatoes, soup, cheeses, chicken, and garlic are evenly distributed throughout the spaghetti.
- Transfer the combined pasta mixture into the prepared baking dish, spreading it into an even layer.
- Evenly sprinkle 1 cup shredded mozzarella cheese over the top of the casserole, covering the surface so the cheese melts into a golden, bubbly crust.
- Bake the casserole in the preheated oven for 20 to 25 minutes, or until the cheese on top is melted and lightly browned at the edges and the casserole is bubbling around the sides.
- Remove the dish from the oven and let it rest for 5 to 10 minutes before serving. This resting time helps the casserole set and makes it easier to serve neat slices.
- Serve warm. Garnish with a sprinkle of extra Italian seasoning or freshly chopped herbs if desired.
Serving suggestions
This Chicken Spaghetti Recipe with Rotel Tomatoes pairs beautifully with a simple green salad, steamed vegetables, or crusty bread to soak up the creamy sauce. It also reheats well: store leftovers in an airtight container in the refrigerator for up to 3 days and reheat covered in the oven at 350°F (175°C) until warmed through.
Tips for success
- Drain the spaghetti thoroughly. Excess water is the most common cause of a runny casserole.
- Cut the Velveeta and cream cheese into even cubes so they melt uniformly into the sauce.
- If your Rotel tomatoes are very watery, drain a little liquid before stirring them in to prevent a soupy texture.
- Use pre-shredded chicken that’s been pulled into even pieces—this ensures every bite has chicken distributed throughout.
- Allow the casserole to rest a few minutes after baking so it firms up for cleaner slices.
Variations and swaps
Want to customize this Chicken Spaghetti Recipe with Rotel Tomatoes? Try these easy swaps:
- Add a cup of frozen corn for a sweet pop and color contrast.

- Swap mozzarella for cheddar for a sharper, more pronounced cheese flavor.
Make-ahead and storage
Assemble the casserole and cover it tightly with foil, then refrigerate for up to 24 hours before baking. When ready to bake, add a few extra minutes to the baking time if starting from cold. Leftover portions keep well in the fridge for up to 3 days. Reheat individual servings in the microwave or warm the whole dish covered in a 350°F oven until heated through.
