There is something mighty comforting about a simple bake like this, the kind of dish that looks humble going into the oven and comes out rich, creamy, and good enough to have folks scraping the corners of the pan. This oven baked 4-ingredient rice and potato layer bake reminds me of the casseroles that always showed up at church suppers and neighborhood potlucks across the Midwest, where a few pantry staples could be turned into a filling side dish that fed a table full of people without any fuss.
This casserole goes especially well with baked ham, roast chicken, pork chops, or meatloaf, and it is right at home beside green beans, buttered peas, or a crisp lettuce salad to balance the creaminess. If you are serving it for a casual supper, a spoonful alongside sliced tomatoes or a little dish of pickles makes a fine plate.
Oven Baked 4-Ingredient Rice and Potato Layer Bake
Servings: 6 to 8
Ingredients
1 cup uncooked long-grain white rice
4 medium russet potatoes, peeled and thinly sliced
1 can (10.5 ounces) condensed cream of mushroom soup
2 cups milk
Directions
1. Preheat the oven to 350°F and lightly grease a medium casserole dish.
2. Spread half of the sliced potatoes in an even layer in the bottom of the dish, then sprinkle over half of the uncooked rice.
3. Add the remaining potatoes and remaining rice in a second layer, making sure the rice is distributed as evenly as you can.
4. In a bowl, whisk together the condensed soup and milk until smooth, then pour the mixture evenly over the layered potatoes and rice.
5. Cover the dish tightly with foil and bake for 1 hour. Remove the foil and continue baking for 20 to 30 minutes more, or until the potatoes are tender, the rice is soft, and the top is lightly golden.
6. Let the casserole rest for 10 to 15 minutes before serving so the creamy layers can settle and scoop neatly.
Variations & Tips
Add a Little Seasoning: If your family likes a little more flavor, stir in a pinch of black pepper, onion powder, or garlic powder with the soup and milk. Even though the original is wonderfully plain and old-fashioned, a touch of seasoning can wake it up nicely.
Slice Thin for Best Texture: The potatoes need to be sliced thinly and evenly so they cook through in the same amount of time as the rice. A mandoline makes quick work of it, but a steady hand and sharp knife do the job just fine.
Try a Different Soup: Cream of chicken or cream of celery soup can be used instead of cream of mushroom if that is what you have in the pantry. Each one gives the casserole a slightly different character while keeping that same creamy, cozy texture.
Make It Potluck-Friendly: This bake holds heat well and travels nicely once covered, which is one reason it has long been a favorite for suppers and carry-ins. Let it stand a bit before transporting so the sauce thickens and the layers stay together better on the serving spoon.
