Bring 5 cups of water to a boil. Add both Lipton soup packets and cook for 7 minutes. Set aside.
In a large skillet, sauté the sausage, onion, and celery over medium-high heat until browned. Drain any excess fat.
In a 9×13 casserole dish, combine the sausage mixture, cooked soup, and uncooked rice. Stir well.
Cover tightly with foil or a lid and bake for 1 hour, until the rice is tender and liquid is absorbed.
Rest for 5–10 minutes before serving.
Notes
Use regular uncooked rice, not instant. Add grated cheese on top for the final 10 minutes for a golden crust. Leftovers keep well in the fridge for 3 days or in the freezer for up to 3 months.
