How to Make French Onion Chicken and Rice Casserole

You’ll need simple pantry staples to make this recipe:

  • Wild Rice Mix – I love this wild rice blend! Be sure to purchase the one with the seasoning packet. I keep this boxed rice mix in my pantry for an easy side dish, or stir it into soups, it makes a great base for Poppy Seed Chicken casserole, too!
  • Onion Soup Mix – this is what makes this French Onion Chicken Casserole! This little packet is PACKED with flavor!
  • Cream of Mushroom Soup – it’s not a casserole unless you’ve got a can of creamy of something soup, huh?!
  • Sour Cream – sour cream in a casserole is just delightful! It adds a tangy flavor you’ll begin to miss when you don’t use it.
  • Chicken – I baked boneless skinless chicken breasts in the casserole, then shredded them up. But! If you have a rotisserie chicken you could definitely use that and save a ton of time!
  • French Onions – the crunchy ones you use for green bean casserole!

After you’ve gathered your ingredients you’ll need a casserole dish or a braiser pot like the one pictured.

Start by drizzling a couple of tablespoons of olive oil into the bottom of your casserole dish. I like the flavor of olive oil, but feel free to use cooking spray! You just want to make sure nothing sticks!

To a large mixing bowl, add the packaged rice mixture, a packet of french onion soup mix, a can of cream of mushroom soup, sour cream, and a can of water.

Mix all of this together, until evenly combined.

Lay your chicken breasts on the bottom of your baking dish.

If you are starting from raw, uncooked chicken. Read further down in the printable recipe card for instructions on cooking this french onion chicken and rice casserole with rotisserie chicken!

Salt and pepper the chicken on both sides, then pour the soup and rice mixture over the chicken breasts.

Slice up fresh onions and lay them on top. This is totally optional! I love Vidalia onions, and wanted some fresh onion flavor in the casserole!

Sprinkle the wild rice seasoning mix over the entire casserole, along with half a stick of butter. Just dot the butter over the top.

Bake the casserole, covered for 30 minutes, covered.

Once your chicken is cooked through to 165 degrees internally, shred the chicken, and mix the casserole up.
