Easy French Onion Chicken and Rice Casserole

THIS IS THE BEST casserole, EVER!! When my boys were little, all I had to do to make them eat a casserole was top it with French fried onions! (It worked on my ex-husband, too LOL)It’s the trick to get your kids to actually eat the dinner you prepare! Also, you may not know this about me, but I was a teacher and reading specialist in the Palm Beach County school district for MANY years before I started creating content online. (I went viral on TikTok during the pandemic on a fluke and the rest is history) SO, all my best casseroles I created for my family I can teach you! SO I guess I am still teaching. LOL Long story longer…this was my kids favorite casserole when they were little and they still devour it today at 22 & 25 years old! One of my most viral french onion casseroles was my easy french onion and chicken casserole, so I decided to share this one, too! This time I replaced the noodles with fluffy white rice and an absolute star was born and her name is easy french onion chicken and rice casserole! And just like her predecessor she’s easy, wildly creamy, and buttery crunchy on top! With the french onion flavor bursting at the seams! 

I do have a few tricks up my sleeve, so don’t be surprised if you’ve made another version of this casserole from somebody else’s website. When you see Worcestershire, just a few splashes in the casserole and in the crunchy topping. Worcestershire, is the secret sauce that gives this casserole LIFE!! 

If you love easy dinners and also love french onion, well then I guess you’re going to have to make these recipes too!

Melissa Jo’s Tips!

• Make sure you use cooked rice for this recipe. Do not add uncooked rice directly to the casserole.
• I used jasmine rice, but any cooked white rice you enjoy should work. You can use a different kind a rice as well!
• Rotisserie chicken makes this recipe incredibly easy, but leftover cooked chicken can also be used.
• Lightly crush the crispy fried onions, but do not crush them into crumbs. You still want plenty of crunchy texture on top.
• Bake the casserole uncovered and a middle to middle lower rack, so the crispy onion topping stays golden and crunchy.
• Let the casserole rest for a few minutes after baking so the filling can set slightly before serving.
• If you prefer noodles instead of rice, try my Easy French Onion Chicken Casserole!

Ingredients

  

1x2x3x?

• 2 cups shredded rotisserie chicken
• 2 cups cooked white rice I used jasmine rice
• 1 can Campbell’s Cream of Chicken with Herbs Soup
• 1 cup sour cream
• ½ cup Hellmann’s mayonnaise
• 1 packet Lipton Onion Soup Mix
• A couple shakes of Worcestershire sauce
• 1 cup shredded mozzarella cheese
• 5 slices provolone cheese
• 1 cup crispy fried onions
• 3 tablespoons butter melted
• A few additional shakes of Worcestershire sauce
• Cooking spray or butter for greasing the casserole dish

Method

 

Step 1: Make the Creamy Chicken and Rice Mixture

1. Preheat your oven to 350°F and grease a 9-by-9-inch casserole dish.
2. In a large bowl, add the shredded rotisserie chicken, cooked white rice, cream of chicken with herbs soup, sour cream, mayonnaise, Lipton Onion Soup Mix, a couple shakes of Worcestershire sauce, and shredded mozzarella cheese.
3. Mix everything together until the chicken and rice are completely coated in the creamy mixture and all of the ingredients are evenly combined.

Step 2: Assemble the Casserole

1. Transfer the chicken and rice mixture into the greased 9-by-9-inch casserole dish.
2. Spread it out into an even layer, making sure to press the mixture into the corners of the dish.
3. Arrange the five slices of provolone cheese evenly over the top of the casserole. I cut one of the slices in half so it fit perfectly!

Step 3: Make the Crispy Onion Topping

1. Crush up the crispy fried onions right in the bag they come in (if you bought the same brand as me). If you are you using French's crispy fried onions, pour one cup into a ziplock and follow the same instructions.
2. Pour in the melted butter and add a few shakes of Worcestershire sauce. Mix everything together until the crispy onions are evenly coated.
3. Sprinkle the buttery crispy onion mixture evenly over the provolone cheese.

Step 4: Bake the Casserole

1. Bake the casserole uncovered on the middle or lower middle rack, at 350°F for 30 minutes, or until the filling is hot and bubbly and the crispy onion topping is golden brown.
2. Remove the casserole from the oven and allow it to cool for a few minutes before serving. This gives the creamy filling a chance to settle so it is easier to scoop.
3. Serve it up and enjoy!

Reheat individual portions in the microwave until hot. Keep in mind that the crispy onions will soften slightly once the casserole is refrigerated, but it will still taste delicious.
