Step-by-Step Beginner-Friendly Instructions

  1. Preheat + prep dish: Preheat oven to 425°F (220°C). Spray a 9×13-inch baking dish with cooking spray.
  2. Brown the beef: In a large skillet, cook ground beef over medium-high heat. Season with garlic salt. Crumble and cook until browned and no pink remains (about 6–8 minutes).
  3. Combine in the dish: Add uncooked rice to the baking dish. Spoon in the cooked ground beef.
  4. Add liquids: Pour in French onion soup, beef consommé, and water. Stir well until the rice is evenly mixed in. 🍚
  5. Top with butter: Place butter slices evenly across the top (this helps it turn rich and flavorful). ✨
  6. Bake covered: Cover tightly with foil and bake 30 minutes.
  7. Bake uncovered: Remove foil and bake 30 minutes more until rice is tender and liquid is absorbed.
  8. Fluff + serve: Fluff with a fork and serve hot. 😋

Multitask tip: While it bakes, prep a simple side salad or steam green beans.

Pro Tips

  • Seal the foil well: This traps steam so the rice cooks evenly.
  • Cheesy upgrade: In the last 10 minutes, sprinkle on 1 1/2 cups cheese and bake until melty. 🧀
  • Crunchy topping: Add crispy onions or crispy jalapeños during the last 10 minutes so they stay crisp.
  • Storage: Refrigerate leftovers in an airtight container for up to 4 days. Reheat with a splash of broth or water.
