Ingredients (for 4-6 servings):
- 1 cup long-grain white rice
- 2 cups beef broth
- 3 large onions, thinly sliced
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon sugar
- 1 teaspoon salt, divided
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried thyme
- 1 cup shredded Gruyère cheese
- 1/2 cup grated Parmesan cheese
- 1/4 cup fresh parsley, chopped (optional for garnish)
Cooking Instructions:
- Preheat the Oven: Begin by preheating your oven to 350°F (175°C). This guarantees the oven is hot and ready for the casserole when it’s assembled.
- Caramelize the Onions: In a large skillet over medium heat, melt the butter with the olive oil. Add the sliced onions, sugar, and 1/2 teaspoon of salt. Cook the onions, stirring occasionally, until they’re golden brown and caramelized, about 20-25 minutes. This step is essential for developing the deep, sweet flavor characteristic of French onion dishes.
- Cook the Rice: While the onions are caramelizing, rinse the rice under cold water until the water runs clear. In a medium saucepan, bring the beef broth to a boil. Add the rice and the remaining 1/2 teaspoon of salt, reduce the heat to low, cover, and simmer for 15 minutes or until the rice is tender and has absorbed the broth.
- Combine Ingredients: In a large bowl, combine the cooked rice and caramelized onions. Add the black pepper and dried thyme, mixing well to confirm the flavors are evenly distributed.
- Assemble the Casserole: Transfer the rice and onion mixture into a lightly greased 9×13-inch baking dish. Sprinkle the Gruyère and Parmesan cheeses evenly over the top.
- Bake: Place the dish in the preheated oven and bake for 15-20 minutes, or until the cheese is melted and bubbly.
- Garnish and Serve: Remove the casserole from the oven and let it sit for a few minutes before garnishing with fresh parsley, if using. Serve warm.
Extra Tips:
For an even deeper flavor, consider using a mix of different types of onions, such as sweet onions or shallots, in addition to the standard yellow onions.
If you prefer your casserole to have a bit more texture, try adding sliced mushrooms or a handful of chopped spinach to the onion mixture before baking. Additionally, for a crispier top, you can finish the casserole under the broiler for a minute or two—just be sure to watch it closely to prevent burning.

- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- 1 cup shredded Gruyère cheese
- 1/2 cup breadcrumbs
- 1/4 cup grated Parmesan cheese
- 2 tablespoons fresh parsley, chopped
Cooking Instructions:
- Preheat the Oven:
- Preheat your oven to 350°F (175°C) to prepare for baking the casserole.
- Cook the Onions:
- In a large skillet, melt the butter with olive oil over medium heat. Add the sliced onions, salt, and pepper. Sauté the onions, stirring occasionally, until they’re caramelized and golden brown, about 20-25 minutes.
- Prepare the Rice:
- While the onions are cooking, rinse the rice under cold water until the water runs clear. In a medium saucepan, bring the beef broth to a boil. Add the rice, reduce the heat to low, cover, and simmer until the rice is tender and the liquid is absorbed, about 15 minutes.
- Mix the Casserole Base:
- Once the onions are caramelized, stir in the thyme and rosemary. Combine the cooked rice and onions in a large mixing bowl. Add the shredded Gruyère cheese and mix well until everything is evenly combined.
- Assemble the Casserole:
- Transfer the rice mixture into a greased 9×13-inch baking dish, spreading it evenly. In a small bowl, mix the breadcrumbs and Parmesan cheese. Sprinkle the breadcrumb mixture evenly over the top of the rice.
- Bake the Casserole:
- Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the top is golden and crispy.
- Garnish and Serve:
- Remove the casserole from the oven and let it cool for a few minutes. Sprinkle the freshly chopped parsley over the top before serving.
Extra Tips:
For a deeper flavor, consider using a combination of beef and chicken broth. If you prefer a vegetarian version, substitute the beef broth with vegetable broth.
Make sure the onions are well caramelized for the best flavor; patience is key here. You can also experiment with different cheeses, such as Swiss or cheddar, for a different taste profile.
If you want to prepare this dish ahead of time, assemble the casserole and refrigerate it, then bake it just before serving for a convenient and delicious meal.
