Ultimate Baked Chicken Spaghetti Casserole is easy, cheesy and packed full of comfort. It’s tender chicken combined with pasta and a cheese sauce baked until bubbling hot and delicious.
I am not really sure where this recipe first originated, but I remember having a version of this that was made by a local catering company at an event at a friends house a hundred years ago. I knew it would be a hit with my family so I asked what was in it from one of the staff.
They said Rotel and Velveeta. Duh – thus why it was a hit! The ingredients are the startings of our favorite queso and add in chicken and spaghetti and BOOM = yumminess. I knew there must be a few add ins. So home I went to figure out the rest.
I tested the chicken spaghetti casserole recipe out on the family and they loved it. It now finds its way into our meal rotation on a normal basis along with my Ultimate Baked Spaghetti and Taco Spaghetti Bake. Y’all give those a try I think you will love them too!

I’ve never felt like I needed to leave feedback on a recipe for but this is awesome! The only changes I made were to use Mexican Velveeta instead of regular and added in a small can of green Chiles. It was so good, it was requested again for the next night! I’m going to try to sub the spaghetti with cauliflower soon so I can eat more of it…I’m the low carb one of the house. Lol
Nicole, I am so glad to hear you enjoyed this. I love your slight changes to spice it up even more. I still haven’t tested this with cauliflower, but I bet it would be delicious. If you love this one you may enjoy my taco spaghetti bake too! It’s another family favorite!
Can I use ground beef in this recipe?
It would change up the flavor but I think it would be delicious!
Can this be refrigerated to cook later that day?
Yes, you can prepare ahead of time. The cook time will likely be closer to 40 or 45 minutes though.
Looks delicious! A great family meal.
Thank you so much!
That looks like something my family is going to love too! You can never have too many dinner ideas in the arsenal.
I think they will too! It definitely is a family favorite at our house. Cheesy is the key I think ?!
How much cube velveeta cheese didn’t see that in your ingredients list!
16 ounces. Thanks for letting me know, I have updated the card Enjoy!
