This French Onion Soup Rice recipe brings the rich, savory flavors of classic French onion soup together with tender, perfectly baked long grain rice. It’s a cozy, comforting dish that feels homemade yet can come together with ease. The butter melting on top during baking creates a luscious finish that makes this a versatile side or simple main.

I first tried this on a chilly evening when I wanted all the flavor of French onion soup but with a twist. It quickly became a favorite, especially when I wanted something warm without a lot of fuss.

Ingredients

  • Long grain rice: one cup provides fluffy texture that soaks in the rich liquid without becoming mushy choose good quality rice for best results
  • Campbell's French Onion Soup: ten ounces adds the iconic sweet and savory onion flavor that defines the dish Campbell's version is classic and reliable
  • Beef broth: ten ounces deepens the savory notes bringing a hearty dimension opt for low sodium if you want to control salt levels
  • Butter: half a cup sliced melts over the top creating richness and a golden finish use good salted butter for balance or unsalted if you prefer to control seasoning

Instructions

Mix ingredients:
In an appropriately sized baking dish combine the long grain rice French onion soup and beef broth. Stir gently to distribute everything evenly taking care that the rice is immersed in the liquid This step ensures the rice cooks uniformly
Pure melted butter:
Place the sliced butter evenly on top of the rice mixture. As it melts in the oven it will impart creaminess and a rich flavor that ties the dish together
Cover and bake:
Cover the dish tightly with foil to keep moisture locked inside. Place it in a preheated oven at four hundred twenty-five degrees Fahrenheit two hundred twenty degrees Celsius and bake covered for about twenty-five minutes This allows the rice to begin absorbing liquid and softening
Bake uncovered:
After the initial covered bake remove the foil and continue cooking for another twenty to twenty-five minutes or until the rice is tender and the liquid is fully absorbed The top should develop a slight golden crust removing the casserole from the oven too early will leave the rice underdone
Rest briefly and serve:
Let the dish rest a few minutes after baking to allow steam to settle and the rice to firm up slightly Serve it hot as a cozy side or a simple main

French onion soup is my favorite ingredient here because it carries both sweetness and umami making the rice unusually flavorful. I remember the first time I served this to my family the buttery topping was gone almost immediately. It’s one of those moments where simple ingredients combine to feel special and indulgent.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to three days. Reheat gently covered so the rice does not dry out You can add a splash of broth when reheating to refresh moisture

Ingredient Substitutions

If you don’t have Campbell's French Onion Soup use another quality brand or homemade French onion soup for a fresher flavor Beef broth can be swapped for vegetable broth to keep the dish lighter or for a vegetarian variation Butter can be replaced with olive oil for a dairy-free option though you lose some richness

Serving Suggestions
