Notes
The spaghetti continues to cook as the casserole bakes in the oven, so it’s important not to over cook the pasta in the beginning.
Letting the casserole rest for 5-10 minutes after it comes out of the oven will help with slicing and serving if you want to serve it up in squares.
Ideal for assembling ahead of time, refrigerating and baking the next day. Add an extra 10 minutes to the baking time.
Mexican Spaghetti can be frozen before or after baking. If freezing after baking, make sure the casserole is completely cooled before freezing.
