Coat a large pan in butter, oil, or nonstick cooking spray. Add your chicken, broccoli, onion, celery, salt, pepper, garlic powder, and onion powder. Cook the ingredients over medium heat for about 7-10 minutes, or until the chicken is cooked through all the way.
Add the cream of chicken soup and half of the cheddar cheese. Fold the mixture together and continue cooking over medium heat until the cheese is completely melted.
Transfer the chicken mixture to a 9x13 inch baking dish and top it with the remaining cheese. Melt the butter in the microwave and then use a fork to fold in the breadcrumbs. Sprinkle the breadcrumb mixture over the cheese.
Bake your chicken divan in the oven for 30 minutes, or until the dish is bubbly and the breadcrumbs begin to brown.
Serve over cooked white rice and enjoy!
Notes
You can serve your chicken divan straight from the oven or let it sit on the counter for 10-15 minutes so that it sets back up a little bit. Much like lasagna, this dish will thicken as it cools.
If you have fresh broccoli then you can use that instead. Make sure you have about 3 cups of broccoli after it is cut into florets.
You can store your leftover chicken divan in the fridge for up to a week. Reheat a serving of your leftovers in the microwave safe bowl covered with a paper plate or towel. Start with 40 seconds and then stir the leftovers. Continue cooking for 20 seconds at a time until the leftovers are warm.
1 cup of diced onion is the equivalent of about ½ of a large onion. 1 cup of diced celery is the equivalent of 2 large stalks of celery.
For some extra flavor in your topping, try using Italian seasoned panko breadcrumbs instead of regular panko breadcrumbs.
