Ingredients

  • 2 large yellow onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 1 cup uncooked long-grain white rice
  • 2 cups low-sodium chicken broth
  • 1 ½ cups cooked chicken, shredded or diced
  • ¾ cup heavy cream (or half-and-half)
  • 1 teaspoon garlic powder
  • 1 teaspoon dried thyme
  • ½ teaspoon dried tarragon (optional)
  • 1 cup baby spinach (optional)
  • Salt and pepper to taste
  • 1 ½ cups shredded Gruyère cheese (or mix of Swiss and mozzarella)
  • Chopped parsley or additional herbs for garnish (optional)

Instructions

  1. Heat butter and olive oil in a skillet over medium-low heat. Add sliced onions, salt, and pepper. Cook for 30–40 minutes, stirring occasionally, until deeply caramelized.
  2. While onions cook, rinse the rice. In a saucepan, combine rice and chicken broth. Bring to a boil, reduce to low, cover, and simmer for 15 minutes. Remove from heat and fluff with a fork.
  3. In a large bowl, mix cooked rice, chicken, cream, garlic powder, thyme, tarragon (if using), spinach (if using), salt, and pepper until combined.
  4. Transfer the rice mixture to a greased 9×13-inch baking dish. Spread caramelized onions on top and sprinkle with shredded cheese.
  5. Preheat oven to 375°F (190°C). Bake uncovered for 20–25 minutes, until cheese is melted and bubbly. Broil for 1–2 minutes if desired for a golden crust.
  6. Let the casserole rest for 5–10 minutes before serving. Garnish with herbs if desired.

Notes

  • Use rotisserie chicken for convenience and added flavor.
  • Add mushrooms or bell peppers for more vegetables.
  • Top with breadcrumbs before baking for a crispier texture.
  • Swap in cooked quinoa or brown rice for variation.
  • Store-bought caramelized onions or onion soup mix can save time.
