Welcome! I’m Sarah, and I’m so happy you’re here. This recipe takes the rich, savory flavors of classic French onion soup and transforms them into a comforting, easy rice side dish. You will cook fluffy rice with caramelized onions, butter, and beef broth for a gourmet taste with minimal effort.

Ingredients

Scale
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced
  • 4 tablespoons unsalted butter, divided
  • 1 (10.5 ounce) can condensed French onion soup
  • 2 cups beef broth
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 cups uncooked long-grain white rice

Instructions

  1. Heat the olive oil and 2 tablespoons of butter in a large, oven-safe pot or Dutch oven over medium heat.
  2. Add the sliced onions and cook slowly, stirring occasionally, for 15 to 20 minutes until they are deeply caramelized and soft. This step builds the French onion soup flavor.
  3. Stir in the remaining 2 tablespoons of butter until melted.
  4. Add the French onion soup, beef broth, salt, and pepper to the pot. Bring the mixture to a simmer.
  5. Stir in the uncooked rice until it is evenly distributed.
  6. Cover the pot tightly with a lid.
  7. Transfer the pot to a preheated oven at 375°F (190°C). Bake for 20 to 25 minutes, or until the liquid is absorbed and the rice is tender. Do not lift the lid during baking.
  8. Remove the pot from the oven and let it stand, covered, for 5 minutes.
  9. Fluff the French onion butter rice gently with a fork before serving as a side dish for steak or chicken.

Notes

  • For a richer flavor, use homemade beef broth instead of canned.
  • If you do not have an oven-safe pot, you can combine all ingredients in a saucepan, bring to a boil, cover, reduce heat to low, and simmer for 20 minutes.
  • This savory rice casserole pairs well with potluck meals.
