Preheat: Start by preheating your oven to 425°F and prepare your baking dish with a light coating of nonstick cooking spray.
Combine: In the baking dish, mix the uncooked rice with the French onion soup and beef consomme, ensuring the liquids evenly coat the grains.
Butter Topping: Arrange the butter slices evenly over the rice mixture, following a 3x3 grid pattern to ensure equal flavor distribution.
Bake Covered: Seal the dish with aluminum foil and bake for 30 minutes, allowing the rice to absorb the flavors.
Bake Uncovered: Remove the foil and continue to bake for another 30 minutes until the rice is tender and fully cooked.
Serve: Once done, fluff the rice gently before serving to ensure it's perfectly light and not clumped together.
