No one loves a good casserole recipe more than a mom. From her perspective, it’s a complete meal, loaded with veggies, and baked all in one dish. It’s easy for serving and cleanup and can be made in advance. And as an added bonus, the recipe can usually be doubled and half of it frozen for another meal!

Besides this cheesy chicken broccoli casserole, my family’s favorite casserole is my sweet potato shepherd’s pie. Both are excellent and easy to make on a busy day.

Easy Cheesy Chicken Broccoli Casserole

It’s easiest to make this recipe with pre-cooked chicken. I frequently cook extra chicken on weekends or when I’m making some for another recipe (like chicken enchiladas verdes) so that I have some ready to go when I’m short on time. However, you can absolutely start with raw chicken and bake it in the oven or dice it and then saute it in a skillet.

I also like to use frozen veggies, again to save on time and prep work. But go ahead and use fresh ones if you’d like. I typically use broccoli and cauliflower because they’re easy to find and my family likes them, but you could also use frozen carrots.

Delegate It to the Kids!

I love to let my kids help cook whenever possible. Letting the kids help cook is one of the ways I help them learn to love a wide variety of foods. It’s also a really great way to help avoid developing picky eaters.

Years ago I enrolled them in an online cooking school. They learned the basics of recipe reading, measuring, and knife safety and loved it. We also have a crinkle cutter with a wooden handle. It’s a great tool for letting little hands help with chopping and grating.

Now that they are older I’m reaping the rewards of the earlier challenges of teaching the kids to cook. My kids are actually a tremendous help many nights and can even cook several meals on their own. The messes and spills we cleaned up by letting them “help” when they were younger have paid dividends.

    We tried the Chicken Broccoli Casserole for the first time last night and the food was great and very tasty

    I don’t eat dairy so I made this recipe without sour cream or cheese and used fresh veggies, not frozen. Based on a previous comment, I microwaved the veggies for 5 minutes first. This strategy worked and they were not crispy. However, I must say that without the cheeses and sour cream, this recipe was a little dry.

    Is there anything to hold this together if you don’t use cheese or sour cream? It says the dairy is optional, and we are dairy free.

    Just made this and added 1 cup of quinoa cooked with chicken broth instead of water. Delicious protein dinner! Going to try freezing a pan too. Thanks!

    What cheese do you use when you say “cheese”? Sorry for the silly question but I really want to make it right and I am sure that I could easily choose the wrong cheese lol

        Thank you so much for clarifying that! Bc I am a procrastinator and asked you this 5 mins before I made dinner I used all Parmesan cheese, though it was still AMAZING thanks to your recipe I will definitely be trying it with white cheddar next time! Thanks again so much and God Bless you for all you do!

    Thank you for this recipe! I am very bad at following recipes exactly, but this one really inspired me and added an easy, delicious, healthy dish to our rotation! I always have onion, garlic, and butter..but I make this dish when I have (now I try to have all of these on hand):
    1. cooked chicken, or breasts that are defrosted and easy to cook
    2. sour cream and/or cream cheese and some sort of other cheese
    3. frozen veggies of just about any sort (have tried broccoli, cauliflower, green bean, artichoke, carrot)

    What I learned from your recipe is that I can dump those frozen veggies into a baking dish (I don’t add butter or onion at this stage) and stick them in the oven while I sauté up some onions and garlic (I also add herbs and other fresh veggies here like mushrooms). Once they are done sautéing I mix them with the sour cream, chicken and cheese and finish off in the oven. Delicious! Everyone loves it.

    Thank you Katie! 🙂

    I made this earlier in the week and I and my husband both loved it. I too, had water in the bottom with crispy veggies so I think I’ll just leave the water out. We don’t mind crunchy veggies. I like that it has the cauliflower also. This will be a perfect “go-to” recipe once I start precooking chickens over the weekend! Thank you!

    I made this this eve. My whole family really liked it!! My family was starving and wanted to eat…..the veggies were still a little crisp and there was quite a bit of liquid in the bottom of the dish. Next time I will allow more cooking time. It seemed to take much longer than the recipe indicated. Might even microwave the veggies a little first. All in all it was a hit.

    Does this Chicken Broccoli Casserole fair well if you freeze it and try to reheat?

    This recipe is delicious!

    A couple of suggestions to help make the instructions easier to follow:

    – Specify what size casserole dish you’ll need for this, as you’ll need a larger one (!).

    – It wasn’t clear what you do with the 4 TBSP of butter by how the recipe is written, and so I assumed it was to use with the onions (see the following).

    – Sauté the onions before you add the frozen vegetables, to ensure the onions get cooked enough and are soft.

    – Include amount of basic and garlic (as well as the type of garlic–fresh chopped? powder?) that you typically use would be great for us new to cooking.

    Thank you for all of your great recipes and articles. 🙂

    Just made this and the reaction from the whole family was ‘Wow’!  Only thing I changed was I fried onion and garlic in butter then added it to casserole with the sour cream.   It’s gone onto our list of regular dinners, thanks.

    I love all of your recipes. The only thing that would make them better is if you can list a “ballpark” time it takes to create these meals. I’ve gotten over my head a few times with some of your recipes that seem like they won’t take much time, but end up consuming my night. Thanks!

      I have the exact same problem, and not just with wellness mama… this will probably take me 2 hours to make ;/
