Can you use other cuts of chicken?
I like to make this recipe with chicken breasts, but you can use sliced chicken thighs as well if you have those to hand.
If you have cooked shredded chicken that you need to use up, you can stir that in at the same time as the pasta.
Can you make it ahead of time?
You can make the whole dish up and then keep it covered in the fridge for up to 4 days, then, you just need to pop it into the oven when you are ready to serve.
Any leftovers will keep well in the fridge for 4 days and can be reheated in the oven at 350F until warmed through.
What do you serve it with?
The beauty of this pasta bake is that you can serve it by itself as a full and hearty meal. You can of course add a veggie side if you like or a side salad. If you want to go carb heavy, garlic bread is never a bad idea!


Recipe Tips and Notes
- Cook the pasta al dente. It will continue to cook in the oven so you don’t want to over cook it.
- I used penne pasta in this recipe, but any shape of short pasta will work well.
- Feel free to add in other veggies. Peas or bell peppers work great!

This is on my “to make” list. Do you think I could divide into 2 8x8s and freeze one before baking? We are a senior couple and it’s just too much in a 9×13.

I don’t see a problem with that!
Erica says
How do you think it would be with jar vodka sauce instead?? We don’t like Alfredo sauce but this looks good!

I think it would work well!
