Make this rich, savory French Onion Butter Rice casserole. It combines the deep flavor of caramelized onions with fluffy rice baked in beef broth and butter, creating a comforting side dish perfect for weeknight dinners or potlucks.

Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 1 large yellow onion, thinly sliced
  • 1 (10.5 ounce) can condensed cream of mushroom soup (or substitute with homemade cream sauce)
  • 1 (10.5 ounce) can condensed cream of chicken soup (or substitute with homemade cream sauce)
  • 1 packet dry onion soup mix
  • 2 cups long-grain white rice, uncooked
  • 2 cups beef broth
  • 1 cup water
  • 1 cup shredded Gruyère or Swiss cheese (optional, for topping)

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. Melt the 2 tablespoons of butter in a large skillet over medium heat. Add the thinly sliced onion and cook slowly, stirring often, until the onions are deeply caramelized and soft, about 15 to 20 minutes. Remove from heat.
  3. In a large mixing bowl, combine the uncooked rice, beef broth, water, dry onion soup mix, cream of mushroom soup, and cream of chicken soup. Stir well to mix the ingredients.
  4. Fold the caramelized onions into the rice mixture.
  5. Pour the entire mixture into the prepared baking dish, spreading it into an even layer.
  6. Cover the baking dish tightly with aluminum foil.
  7. Bake for 50 minutes.
  8. Remove the foil. If using cheese, sprinkle the shredded cheese evenly over the top.
  9. Return the dish to the oven, uncovered, and bake for an additional 10 minutes, or until the rice is tender and the liquid is absorbed.
  10. Let the casserole rest for 5 minutes before serving.

Notes

  • For a richer flavor, use homemade caramelized onions instead of the dry soup mix. Cook the onions low and slow until they are dark brown.
  • If you skip the canned soups, substitute with 1 cup heavy cream, 1 teaspoon garlic powder, and 1 teaspoon dried thyme for a homemade creamy base.
  • This dish pairs well with roasted chicken or grilled steak.
