Ingredients

• 4 tablespoons unsalted butter
• 4 medium (sliced thinly) yellow onions
• 1 cup (uncooked) long-grain white rice
• 2 cups vegetable broth
• 2 minced garlic cloves
• 1 teaspoon (dried) thyme leaves
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 1.5 cups shredded Gruyère cheese
• 0.5 cup breadcrumbs
• 1 tablespoon olive oil
• 2 tablespoons (chopped, for garnish) parsley

Directions

Step 1

Preheat your oven to 375°F (190°C) and grease a 9x13-inch casserole dish with butter or nonstick spray.

Step 2

In a large skillet, melt 2 tablespoons of the butter over medium heat. Add the sliced onions and cook for 15-20 minutes, stirring occasionally, until they are golden and caramelized. Reduce the heat if they start browning too quickly.

Step 3

Add the minced garlic to the onions and cook for an additional 1-2 minutes until fragrant. Remove from heat and set aside.

Step 4

In a medium saucepan, bring the vegetable broth to a simmer. Add the rice, thyme, salt, and black pepper. Stir, cover with a lid, and reduce the heat to low. Cook for 12-15 minutes or until the rice is partially cooked (it will finish cooking in the oven).

Step 5

In a large mixing bowl, combine the cooked rice, caramelized onions, and 1 cup of the shredded Gruyère cheese. Mix well and transfer the mixture to the prepared casserole dish, spreading it out evenly.

Step 6

In a small bowl, mix the breadcrumbs with the remaining 2 tablespoons of melted butter and 1 tablespoon of olive oil. Add the remaining 0.5 cup of Gruyère cheese to the breadcrumb mixture and combine.

Step 7

Sprinkle the breadcrumb-cheese topping evenly over the rice and onion mixture in the casserole dish.

Step 8

Bake in the preheated oven for 25-30 minutes, or until the topping is golden brown and the casserole is bubbling around the edges.

Step 9

Remove the casserole from the oven and let it cool slightly for 5-10 minutes. Garnish with chopped parsley before serving.
