Ingredients

Scale

Rice and Broth

  • 1 cup long-grain rice (basmati preferred)
  • 2 cups vegetable broth
  • 1 tablespoon fresh thyme leaves
  • Salt and pepper to taste

Onion Butter Mixture

  • 3 tablespoons unsalted butter, divided
  • 2 medium yellow onions, sliced

Instructions

  1. Caramelize the Onions: In a large skillet, melt 2 tablespoons of unsalted butter over medium heat. Add the sliced yellow onions and sauté them slowly, stirring occasionally, until they become golden brown and caramelized. This process takes about 15 to 20 minutes, developing the rich, sweet flavor essential for the dish.
  2. Toast the Rice: Add the long-grain rice directly to the skillet with the caramelized onions. Stir and toast the rice for 2 to 3 minutes until it becomes fragrant, which helps enhance the rice’s nutty flavor.
  3. Simmer with Broth and Thyme: Pour in the vegetable broth and sprinkle in the fresh thyme leaves. Increase the heat to bring the mixture to a boil. Once boiling, reduce the heat to low, cover the skillet with a lid, and let it simmer gently for 15 to 20 minutes. Cook until the liquid has been fully absorbed by the rice.
  4. Rest and Add Butter: Remove the skillet from the heat but keep it covered. Let the rice rest and steam for an additional 5 minutes. Afterward, stir in the remaining tablespoon of unsalted butter until it melts completely, adding richness and a velvety texture to the dish.
  5. Fluff and Season: Using a fork, fluff the rice gently to separate the grains. Taste and adjust seasoning by adding salt and freshly ground black pepper according to preference. Serve the French Onion Butter Rice hot as a flavorful side.

Notes

  • Use basmati rice if possible for a fragrant, fluffy texture, but other long-grain rice can substitute.
  • For an even deeper flavor, you can add a splash of white wine when toasting the rice before adding the broth.
  • Ensure slow caramelization of the onions to avoid burning and achieve a sweet, rich taste.
  • This rice pairs wonderfully with roasted meats, grilled vegetables, or as a comforting vegetarian main dish.
  • Leftovers can be refrigerated for up to 3 days and reheated gently on the stovetop or in the microwave.
