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!

    Most times I tweak recipes to suit my tastes but I let this one go and I’m glad that I did!! I’m a mac -n- cheese kinda girl, love my cheese and this recipe is right up my ally. I normally don’t comment on recipes (either) but I felt the need to compliment the chef!! This is excellent!!!

    1. Thank you, Pam! I so appreciate you stopping by to let me know. You have made my day. This one really is a family favorite so your compliment means a lot!

    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

    1. 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!

    1. Yes, you can prepare ahead of time. The cook time will likely be closer to 40 or 45 minutes though.

  3. That looks like something my family is going to love too! You can never have too many dinner ideas in the arsenal.

    1. I think they will too! It definitely is a family favorite at our house. Cheesy is the key I think ?!
