Ingredient Notes
- Pasta – I used pasta shells, feel free to use your favorite type of pasta in this dish, such as bow tie pasta, penne, rigatoni, etc.!
- Chicken – Breasts boneless, skinless, chopped in small 1 inch pieces. You can use chicken thighs as well.
- Olive Oil – Substitute sunflower, safflower or avocado oil.
- Butter – I used unsalted to control the sodium in the dish.
- Tomatoes – Diced tomatoes, canned. You can also use crushed tomatoes.
- Chicken Broth – I always opt for low sodium.
- Herbs – Dried oregano and basil. You can also use a blend of Italian seasoning.
- Garlic and Onion – Essential flavor enhancers.
- Red Pepper Flakes – For a little heat. You can substitute with hot sauce, or nothing at all, if you don’t want any heat.
- Mozzarella Cheese – Shredded. Feel free to use your preference of cheese such as Parmesan, Emmental, Monterey Jack, my only recommendation is to shred your own cheese.

Frequently Asked Questions
What Else Can I Add To This Chicken Casserole?
This casserole is perfect for adding some vegetables to it, such as mushrooms, peppers, zucchini, etc. If looking for a crispy topping, melt some butter and mix it with some breadcrumbs then sprinkle over the top of the casserole before baking.
How to Serve
If you’re looking for a side to pair your chicken casserole with, I would opt for a lighter fare! A salad or a side of roasted vegetables can really round out the meal.

Nutrition Information
Notice: Nutrition is auto-calculated for your convenience. Where relevant, we recommend using your own nutrition calculations.
Two confusing items. You say diced tomatoes in ingredients and crushed tomatoes in instructions. Recipe shows 40 min. Cook time, instructions say 15 to 20 minutes
As it says under ingredients, either work. The total cook time in the recipe card includes the time it takes to cook everything in a skillet and the pasta.
what if I don’t want to add the meat in?
Hi Ana!
You can definitely leave the chicken out of the recipe and substitute it with some vegetables, such as mushrooms, peppers, zucchini, etc.
Let us know how you enjoyed it!
I used a mac&cheese mix in lieu of mozzarella, and also added ~3 cups of chopped broccoli. I baked as recommended for 15 minutes, then broiled a final 5, which made the cheese topping more flavorful. Sauce was a little watery… perhaps because i hadn’t drained the diced tomatoes– or is it because they weren’t crushed instead, as referenced in the instructions?
I truly appreciated the ease of preparation; tho it’s actually a 2-pot meal when you factor in the pasta.
Thanks for sharing the recipe!
So glad you enjoyed it! Yes, it may have been from the tomatoes not being crushed. Let us know how it turns out next time too!
This is absolutely delicious. My hubby isn’t fond of one pan meals but he adored this one and wants to have it again
One more question! If I’ve prepared the dish in the morning and when I take it out to heat it it’s cold from the refrigerator, how long would you suggest I reheat it for?
If you’re just reheating in the microwave it shouldn’t take more than 2 or 3 minutes, but if you put it in the oven, I’d reheat it at 350 for about 20 minutes.
Thanks so much! Can’t wait to try it!
Hi! Could I make it in the morning and refrigerate it (to be baked and served in the evening?)..
Sure
Hi, I’m sorry I never made it on here to review but I have made this at least a half dozen times. Very delicious! I replace the red wine for white if I have it. If not, I use all chicken broth. I also omit the mushrooms b/c of my kiddos but all & all – awesome weeknight dinner that everyone loves! Thank you so much!
Thank you Jessica so much. Hope you try some of my other recipes!
This looks amazing and I started to make it for dinner tonight. Except by the time I altered it to fit with the ingredients I had on hand, it may not have been the same….Poor planning on my part, lol. But it was damn fine just the same. Thanks for a great recipe! Let’s hope the next time, I can make it the way you did 😉
So I meant to give that 5 stars but my mouse slipped and I can’t edit my comment…doh!
Thanks Jenna lol.
Could this be made ahead and put in the freezer? What size of pan do you use to bake this in?
Yes you can freeze it. I used a 12 inch pan.
In the instructions it says 9×13, now u say 12″, which means 8×12 to me. I have it in the oven now in an 8×12 hoping it does not cook over.
The 12″ is for the skillet where you’re cooking the chicken first.
can you suggest a red wine substitute??
Hi Marium,
I would just skip the wine, and add a full cup of the chicken broth. You won’t lose much in the flavor. I just usually add wine to my cooking, because nobody drinks wine at my house, so I have to use it up somehow. 🙂
