French Onion Chicken Rice gives you that warm, cozy feeling in every bite. You'll get tender chicken, rice, creamy soups, gooey cheese, and a golden onion crunch on top. It comes together quickly and always feels like something special right out of the oven. It's perfect after a busy day or when you want to treat your crew to something extra comforting.

The very first time I whipped this together, we were out of groceries except for a few pantry staples. Now it's a go-to comfort meal, and even my pickiest eaters are all about seconds.

Inviting Ingredients

  • Chopped parsley: sprinkle this over at the end for a fresh look and taste
  • Salt and black pepper: makes every bite pop and brings all the flavors together simply
  • Garlic powder and onion powder: punch up the flavor without more chopping work
  • French fried onions: can't skip these if you love that crispy finish, just make sure they're fresh
  • Shredded mozzarella or Swiss cheese: melts perfectly—choose Swiss for a nutty note, mozzarella for that classic cheese pull
  • Sour cream: keeps things tangy, adds moisture so nothing dries out
  • French onion soup: bold and packed with onion flavor, and cans make it a breeze
  • Cream of chicken soup: gets everything nice and creamy, grab a low-salt version if you want
  • Shredded cooked chicken: makes it filling and tasty—rotisserie chicken is a time-saver here
  • Cooked white rice: soak up all those lovely flavors, use leftovers or fresh-cooked, your pick

Simple Step-by-Step

Finish with toppings:
Sprinkle the rest of the fried onions on top, then bake another five minutes so they turn golden and crunchy
Let cool and dig in:
Pull it out of the oven, give it a little time to settle, throw on the parsley, and serve warm. That bit of green makes it look—and taste—even better
Bake it up:
Slide the dish into the oven with no cover, bake for half an hour. When the cheese bubbles and the sides get all nice and crusty, you're good
Mix up the filling:
Stir together your cooked rice, shredded chicken, both soups, sour cream, shredded cheese, onion powder, garlic powder, black pepper, salt, and a cup of fried onions. Mix well so every bite is the same
Prep your dish:
Grease a 9x13 pan with oil or nonstick spray, then spread in your big bowl of filling
Warm up the oven:
Set it for 350 F, or 175 C, so everything bakes evenly and gets bubbly

I can't get enough of those crispy fried onions—they're honestly what makes this dish next level. Guests always love the extra crunch too. One time my kid sneaked a handful straight from the can because they couldn't wait for dinner.

Easy Storage

Leftovers keep well in the fridge for four days if you seal them up tight. Reheat covered in a 350 oven or nuke a portion in the microwave. For freezing, save the crispy onions for after it’s thawed and heated so they stay crunchy.

Smart Swaps

No Swiss or mozzarella? Monterey Jack works great for melty cheese vibes. If you need dairy-free, try plant-based sour cream and cheese, plus go for cream of mushroom soup instead of chicken. Rotisserie chicken is handy but turkey or pork work too!

Serving Ideas

Serve this bubbly bake with a crisp green salad or some roasted veggies—easy way to add color and crunch. For brunch, it’s tasty next to scrambled eggs or with a fresh fruit salad on the side.
