Healthy Chicken Broccoli Casserole Recipe


No one loves a good casserole recipe more than a mother. From her perspective, it’s a complete meal, packed with vegetables and baked all in one dish. It is easy to serve and clean up and can be made ahead of time. And as an added bonus, the recipe can usually be doubled and half frozen for another meal!

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

Easy Cheesy Chicken Broccoli Casserole

It is easiest to make this recipe with precooked chicken. I often cook extra chicken on the weekend or when I’m making some for another recipe so I have some ready to go when I’m short on time. However, you can definitely start with raw chicken and bake it in the oven or cut it into cubes and then fry it in a skillet.

I also like to use frozen vegetables, here too to save time and prep work. But go ahead and use fresh ones if you want. I usually use broccoli and cauliflower because they are easy to find and my family likes them, but you can also use frozen carrots.

Delegate it to the kids!

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

Years ago I registered them in a online cooking school† They learned the basics of reading, measuring and knife safety from recipes and loved it. We also have a crumple shape with a wooden handle† It’s a great tool to help little hands with chopping and grating.

Now that they are older, I am reaping the benefits of the earlier challenges of teaching the children how to cook. My children are a huge help many nights and can even prepare several meals themselves. The messes and spills we cleaned up by letting them “help” when they were younger paid off.
