Its fall and we tend to lean towards warm and comforting dinner ideas to serve our family that can be made in just about 30 minutes and all in one dish! This healthy chicken casserole recipe has the perfect sweet and savory flavors, loaded with protein and veggies, and so easy to put together.

How to make this Baked Chicken and Potato Casserole

Making this cheesy chicken casserole can’t get any easier. I used chicken breasts as a leaner and healthier option to using chicken thighs.

First, cook the chicken chunks in a skillet with a bit of oil until they are cooked through. This will take about 4 minutes or so. In the meantime, add the potatoes and Brussel sprouts onto a baking dish. Add the garlic and the spices.

Drizzle with a bit of oil, salt, and pepper, and toss to combine. Add in the chicken and the broth. Bake for about 15 minutes until the veggies are tender.

Finally, add in the cranberries and cheese. Let it bake until cheese melts and serve. Add whatever garnishes you like. This will be the best chicken casserole ever! Even though I really also like my zucchini Lasagna casserole as well!

The best way to prepare the chicken for the casserole is to cook on a skillet for a few minutes before adding to the baking dish and baking. In my opinion, I have found this to be the easiest route. You can still add the chicken raw with the veggies and bake but keep in mind that the veggies will cook much faster than the chicken. So I suggest you bake the chicken first for about 10 minutes and then add in the veggies.

If you are using pre-cooked chicken like a rotisserie or cooked the chicken in a skillet first, then the chicken casserole needs about 15 minutes in a preheated oven at 350 F. I used a smaller piece of chicken breast chunks that were cooked in a skillet first. Raw chicken will take longer and larger pieces of chicken will take about 30-40 minutes.

This harvest chicken casserole recipe in itself is a well-balanced meal because it is made with chicken breast, veggies, and sweet potatoes. It has the carbs and the protein. You really do not need a side dish but if you feel like having “something” with this chicken casserole, try some quinoa, more grilled veggies, some grilled corn, and greens (like a salad). Other casseroles that don’t have potatoes in them will be great to add a side of baked potatoes to it.

It is ok to freeze your leftover chicken casserole. Make sure you place in an airtight container or tightly wrap with aluminum foil then wrap with plastic wrap before you freeze. When you are ready to use, remove and allow to thaw in the fridge overnight before placing it again in the oven to bake and heat. You can freeze chicken casserole for up to 3 months.

Yes. The best way to reheat chicken casserole is to bake again in the oven at 350F for about 10-15 minutes. You may add a bit more cheese to it. If it’s frozen, allow it to thaw on counter or overnight in the fridge. You may also add it frozen to the oven but will take longer to heat.

    Great concept. But rather poorly written cooking instructions. The veggies take *longer* than the chicken. There is a hefty amount of dense, raw vegetables which take awhile in the oven. Just be smart about how things are being cooked and this will work out!

    A very hearty dish and perfect for meal prepping. The flavor wasn’t too strong, so I can taste each ingredient. The cheese added a layer of flavor, so I recommend it with cheese.

    However, it took more than a good 40 mins to cook everything in the oven, and I had to toss them few times as well.
