A delightful twist on a classic mushroom rice dish, enhanced with creamy textures and rich flavors.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking throughout the dish.
In a mixing bowl, combine the rice, chopped onion, sliced mushrooms, cream of mushroom soup, melted butter, milk, salt, and pepper.
Ensure all ingredients are well mixed for consistent flavor.
Transfer the mixture into a 2-quart casserole dish and cover with aluminum foil.
Covering the dish helps retain moisture during baking.
Bake in the preheated oven for 1 hour.
Check halfway through to ensure the rice is cooking evenly.
Remove from the oven, let it rest for 5 minutes, then fluff with a fork before serving.
Letting the dish rest allows the flavors to settle.
