Ingredients
- 2 tablespoons butter
- 2 large yellow onions, thinly sliced
- 2 cloves garlic, minced
- 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
- 1 cup long-grain white rice, uncooked
- 2 cups beef broth (or vegetable broth for vegetarian option)
- ½ teaspoon salt (adjust to taste)
- ¼ teaspoon black pepper
- 1 teaspoon Worcestershire sauce (optional but recommended)
- 1 cup shredded Gruyère cheese (or Swiss cheese)
- ½ cup shredded mozzarella cheese
- 2 tablespoons chopped fresh parsley for garnish
Instructions
- Preheat oven to 375°F (190°C). Lightly grease a medium baking dish with butter or cooking spray.
- Caramelize the onions. In a large skillet over medium heat, melt the butter. Add sliced onions and cook slowly for 15–20 minutes, stirring occasionally, until soft, golden, and deeply caramelized.
- Add garlic and herbs. Stir in the minced garlic and thyme, cooking for about 1 minute until fragrant.
- Combine rice and broth. Add the uncooked rice to the skillet and stir to coat with the onion mixture. Pour in the broth, salt, pepper, and Worcestershire sauce. Stir well.
- Transfer to baking dish. Pour the mixture into the prepared baking dish and spread evenly. Cover tightly with foil.
- Bake the rice. Place in the oven and bake for 30–35 minutes, or until the rice is tender and liquid is absorbed.
- Add cheese topping. Remove foil, sprinkle Gruyère and mozzarella evenly over the top.
- Final bake. Return to the oven uncovered and bake for another 10–15 minutes until cheese is melted and bubbly. For a golden crust, broil for 2–3 minutes at the end.
- Garnish and serve. Sprinkle with fresh parsley and let rest for 5 minutes before serving.
The Secret to Perfect Caramelized Onions
The heart of this recipe is the caramelized onions. While it might be tempting to rush the process, patience creates the best flavor. Cooking onions slowly allows their natural sugars to develop, creating that signature sweet, savory depth associated with French onion dishes.
Tips for success:
- Use medium heat — too high will burn them.
- Stir occasionally, not constantly.
- Add a splash of broth if they begin sticking.
Properly caramelized onions should be golden brown, soft, and jam-like.
Best Cheese Choices for Maximum Flavor
Gruyère is traditionally used because of its nutty richness and excellent melting quality. However, you can substitute or combine with:
- Swiss cheese
- Mozzarella
- Fontina
- Provolone
- White cheddar
A mix of cheeses often creates the best flavor and texture.

Flavor Twists
