How to Make

This French onion chicken casserole is so easy to make!

Just mix the hash brown, chopped chicken, dip, soup, cheese, and seasonings together until they are evenly combined in a large bowl.

Spread the mixture out in an even layer an 8×8″ baking dish sprayed well with nonstick spray.

Top the casserole with a layer of crispy onions.

Cover the dish tightly with foil and bake it at 350 for 40 minutes.

After 40 minutes, carefully remove the foil and then bake it for another 10-15 minutes.

When the top of the casserole is golden take the dish out of the oven and let it rest for a few minutes.

Serve and enjoy!

Tips and Tricks

  • Make sure to spray the baking dish well with nonstick spray to make for easier clean up.
  • Do not skip the foil for the first part of the baking. The foil keeps the onions from burning.
  • Make sure to let the casserole rest before serving to give it a chance to set a bit.
