There is something mighty comforting about a simple casserole that turns a handful of pantry staples into a bubbling supper dish everybody wants a second helping of. This oven baked 4-ingredient navy bean and potato casserole is the sort of humble Midwestern table fare that has fed church basements, family reunions, and cool-weather suppers for generations. With soft sliced potatoes, tender navy beans, and a creamy baked finish, it is proof that plain ingredients, treated kindly, can make a meal that tastes rich and memorable.
Serve this casserole alongside ham, smoked sausage, roast chicken, or a simple plate of buttered green beans for a well-rounded meal. It also fits right in at a potluck with crisp coleslaw, pickled beets, a fresh cucumber salad, or warm dinner rolls to catch every bit of the creamy sauce. If you are serving it as a main dish, a little fruit on the side and a leafy salad make it feel complete without much fuss.
Oven Baked 4-Ingredient Navy Bean and Potato Casserole
Servings: 6
Ingredients
4 medium russet potatoes, peeled and thinly sliced
2 cans (15 ounces each) navy beans, drained and rinsed
1 can (10.5 ounces) condensed cream of mushroom soup
1 cup milk
Directions
1. Preheat the oven to 375°F and lightly grease a medium casserole dish.
2. In a bowl, stir together the condensed soup and milk until smooth and pourable.
3. Arrange half of the sliced potatoes in the bottom of the casserole dish, then scatter over half of the navy beans. Spoon over some of the soup mixture. Repeat the layers with the remaining potatoes, beans, and soup mixture.
4. Cover the dish tightly with foil and bake for 50 minutes.
5. Remove the foil and continue baking for 20 to 25 minutes, or until the potatoes are tender and the top is lightly golden and bubbling. Let the casserole rest for 10 minutes before serving.
Variations & Tips
For extra flavor: If your pantry allows for a little more than the four basics, a small chopped onion layered in with the potatoes adds a gentle sweetness that bakes right into the casserole. A pinch of black pepper on top is nice too.
For easier slicing: Cut the potatoes as evenly and thinly as you can so they cook at the same rate. A mandoline makes quick work of this, but a sharp knife and a steady hand do just fine.
For a heartier supper: This casserole can be served as a meal on its own, but it also welcomes diced cooked ham or browned sausage if you want to stretch it for hungry folks. Add the meat between the layers.
For a softer, creamier bake: If your potatoes are still a touch firm at the end of baking, cover the dish again and give it another 10 minutes. Letting the casserole rest before serving helps the sauce settle and makes each spoonful creamier.
For make-ahead cooking: Assemble the casserole earlier in the day, cover, and refrigerate. When ready to bake, let it sit at room temperature for about 20 minutes first, then bake as directed, adding a few extra minutes if needed.
