Grandma’s Recipe
My husband’s grandma sent me this recipe as a response to the original email I sent out that started this wild ride, learn more on that on my about page. I had some leftover turkey breast from when I made homemade turkey and egg noodles.
This recipe seemed like a great way to use it up. Obviously you can used leftover roast chicken, chicken breasts or you could pick up a rotisserie chicken at the store.

I knew I would be on the road, so I made the casserole the night before up until the point you put the cheese on it. Then I put it in the refrigerator.
When I got home from work, all I had to do was pull it out of the fridge and preheat the oven. I added a few minutes to the bake time because the casserole started cold. Everyone was a fan of this one.
The first time we had it everyone raved about it. Now I keep it in my back pocket for whenever I have some leftover poultry. So I pull it out a few times a year.

I think the boys in this house have limited memory, so they act like it is the first time they see it ever time. But they love it every time!
If you are looking for a quick and tasty way to change up leftovers, this is the recipe for you. But don’t let lack of leftovers get in your way. It is definitely worth cooking up some chicken breasts too.
Can I use fresh broccoli in this recipe?
Yes! If you prefer to use fresh broccoli instead of frozen broccoli florets, you can certainly do that. Fresh broccoli takes a little bit longer to cook though.
So if you want tender broccoli you may want to partially cook it before you add it to the casserole. You can steam it for a few minutes or put it in the microwave for a minute or two and then add it to the recipe.

Grandma was definitely on the right track sending us this one! I need to ask her if she has any more like this in her recipe box.

Assemble It Ahead Of Time
If you want to prepare the recipe ahead of time, just follow the instructions in the recipe card up until it goes in the oven. Cover the casserole dish with aluminum foil and refrigerate.
Chill for up to two days. When ready to bake, take the casserole out of the refrigerator while preheating the oven to take the chill off.
Bake for 10 minutes with the foil on and then remove the foil from the baking dish and cook another 20 minutes or until the sauce is bubbly and the cheese is melted.

Grandmas' recipes are the best! I am grateful for the ones my Grandma shared with me! Can't wait to try this.
They really are! With all that experience and love cooked in, it's hard not to love grandma's food. This is one we have really enjoyed. It's simple and comforting!
This looks like the perfect weeknight meal for the family. PINNED!
It really is a family pleaser and so easy! Thanks!
Saving this for later! Grandma's are amazing!!
Aren't they the best? Thank you!
This sounds so good! I make a similar recipe using rice but I love the idea of mixing it up with some noodles. Pinned.
I'll have to try it with rice now!
Would you be willing to share your recipe that uses rice?
Hi Carlee, Grandma knew how to feed the family and keep it quick! I like one dish recipes, the less fuss the better. I usually make a pie with chicken or turkey leftovers, that always goes down well with the family.

Mmmm! Now I wish I would have made a pie too! My husband started eyeing me anxiously when I was using too many leftovers in recipes. He loves the leftovers for sandwiches and he was worried he wouldn't get his fill!
I pinned it for later. I always looking for ways to add veggies to quick meals and this does the trick. Thanks.
This definitely hits on both counts! I hope you enjoy it!
This does look like a great way to use up those turkey leftovers, as well as a fabulous recipe. We like casseroles, and we like grandma's recipes too! Thanks for sharing.
Grandma's recipes are the best, aren't they? This is definitely one that I find myself reaching for every time I have turkey leftovers my husband hasn't already claimed for sandwiches!
I think a chicken casserole is so comforting on a bust weeknight. This looks easy, hearty, filling and tasty! Great recipe Grandma! Have a great start to your week Carlee! xo
Those grandmas seem to know what they are doing! Thank you so much, Andrea!
This is such a great recipe to use those leftovers! I don't mind making it from scratch as well!! Cheezy goodness! What I love the most about it is that I can do the meal prep and keep it in the fridge and bake with the cheese whenever needed!
It is handy to have a recipe you can assemble ahead, isn't it? Thanks Deepika!
