  1. Preheat oven to 375°F (190°C) and grease a baking dish.
  2. Melt butter in a skillet and cook sliced onions until deeply caramelized.
  3. Add garlic and thyme and cook until fragrant.
  4. Stir in rice, broth, salt, pepper, and Worcestershire sauce.
  5. Transfer mixture to baking dish, cover with foil, and bake 30–35 minutes.

Notes

Use vegetable broth for a vegetarian version. Brown rice requires longer cooking time and extra liquid.
