Ingredients

Scale
  • 1 tablespoon olive oil
  • 1 large yellow onion, thinly sliced
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 4 tablespoons unsalted butter, divided
  • 1 (10.5 ounce) can condensed cream of mushroom soup (or cream of chicken)
  • 1 (10.5 ounce) can condensed cream of celery soup
  • 1 cup long grain white rice, uncooked
  • 1 3/4 cups beef broth
  • 1 teaspoon Worcestershire sauce
  • 1/2 cup sour cream or heavy cream
  • 1 cup shredded Gruyère cheese (or Swiss cheese)

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease an 8×8 inch baking dish.
  2. Heat olive oil in a large skillet over medium heat. Add the sliced onion and cook slowly, stirring often, for 15 to 20 minutes until the onions are deeply caramelized and sweet. Season with salt and pepper. Remove the onions from the skillet and set aside.
  3. In the same skillet, melt 2 tablespoons of the butter over medium heat. Add the uncooked rice and toast for 2 to 3 minutes until the edges look slightly translucent.
  4. In a large bowl, whisk together the cream of mushroom soup, cream of celery soup, beef broth, and Worcestershire sauce until smooth. Stir in the toasted rice and the caramelized onions.
  5. Pour the rice mixture into the prepared baking dish. Dot the top evenly with the remaining 2 tablespoons of butter.
  6. Cover the baking dish tightly with aluminum foil. Bake for 45 minutes.
  7. Remove the foil. Stir the rice gently. Mix in the sour cream or heavy cream. Sprinkle the shredded Gruyère cheese evenly over the top.
  8. Return the dish to the oven, uncovered, and bake for another 10 to 15 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
  9. Let the French Onion Butter Rice rest for 5 minutes before serving.

Notes

  • For an even deeper flavor, use high-quality beef broth. This is a great side dish for steak.
  • If you prefer a stovetop method, cook the onions, then combine all wet ingredients and rice in a pot, bring to a simmer, cover, and cook on low for 20 minutes until liquid is absorbed. Stir in cheese at the end.
  • You can substitute the canned soups with homemade béchamel sauce mixed with caramelized onion puree for a fresher flavor profile.
