Create a comforting and flavorful side dish by infusing fluffy rice with the savory taste of caramelized onions, rich butter, and beef broth. This recipe delivers the essence of French onion soup in an easy rice casserole format.

Ingredients

Scale
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced
  • 1 cup uncooked long-grain white rice
  • 1 (10.5 ounce) can condensed cream of mushroom soup (or substitute with 1 cup beef broth for a less creamy texture)
  • 1 cup beef broth
  • 1/2 cup water
  • 1/2 cup (1 stick) unsalted butter, cut into small pieces
  • 1 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 cup shredded Gruyère cheese (optional, for topping)

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease an 8×8 inch baking dish.
  2. In a large skillet over medium heat, melt the olive oil. Add the thinly sliced onions and cook slowly, stirring occasionally, for 15 to 20 minutes until they are deeply caramelized and tender. Remove the onions from the heat.
  3. In a large bowl, combine the uncooked rice, condensed soup, beef broth, water, garlic powder, salt, and pepper. Stir well to mix.
  4. Fold in the caramelized onions and half of the cubed butter into the rice mixture.
  5. Pour the entire mixture into the prepared baking dish. Distribute the remaining butter pieces evenly over the top of the rice mixture.
  6. Cover the baking dish tightly with aluminum foil. Bake for 45 minutes.
  7. Remove the foil. If using cheese, sprinkle the Gruyère evenly over the top. Return the dish to the oven, uncovered, for another 10 to 15 minutes, or until the liquid is absorbed, the rice is tender, and the top is lightly golden brown.
  8. Let the French onion butter rice rest for 5 minutes before fluffing gently with a fork and serving.

Notes

  • For a richer, more authentic French onion flavor, substitute the cream of mushroom soup with 1 cup of high-quality beef broth and 1/2 cup of French onion soup concentrate.
  • This dish pairs well with roasted chicken or grilled steak.
  • If you prefer a one-pot stovetop method, sauté the onions, then add the rice and liquids, bring to a boil, cover, reduce heat to low, and simmer for 18-20 minutes until liquid is absorbed. Stir in butter at the end.
