This oven baked 3-ingredient stewed tomato and potato bake is the kind of humble church-potluck dish that quietly steals the show. My neighbor first brought a version of this to a community supper at our church here in the Midwest, and the pan was scraped clean in no time. It’s little more than sliced potatoes, canned stewed tomatoes, and a bit of salted butter, yet it bakes into something deeply comforting—soft, layered potatoes bathed in a tangy-sweet tomato sauce with browned, caramelized edges. Dishes like this grew out of pantry cooking and potluck culture in the Midwest and South, where a few inexpensive staples were stretched to feed a crowd. If you’re looking for a low-effort, cozy side that feels nostalgic and homey, this is it.
Serve this tomato and potato bake as a side dish alongside roast chicken, baked pork chops, or simple pan-seared sausages. It’s also lovely with a green salad dressed in a sharp vinaigrette to cut through the richness, or with steamed green beans or broccoli for color and crunch. At a potluck, I like to park it next to meatloaf, ham, or a big pot of chili; it acts like a cross between potatoes and a rustic vegetable casserole. For a simple weeknight plate, add a fried or poached egg on top and some crusty bread to mop up the saucy tomatoes.
Oven-Baked 3-Ingredient Stewed Tomato and Potato BakeServings: 6
Ingredients
2 tablespoons salted butter, plus a little extra for greasing the dish
2 pounds russet or Yukon Gold potatoes, peeled and thinly sliced (about 1/8–1/4 inch thick)
2 cans (14.5 ounces each) stewed tomatoes, undrained
Directions
Preheat your oven to 375°F (190°C). Lightly butter a 9x13-inch glass baking dish, making sure to coat the bottom and sides so the potatoes don’t stick.
Peel the potatoes and slice them into thin, even rounds about 1/8–1/4 inch thick. The more uniform the slices, the more evenly they’ll cook and soften.
Spread a thin layer of stewed tomatoes, along with some of their juice, over the bottom of the prepared baking dish. This keeps the first layer of potatoes from sticking and starts the sauce base.
Arrange a layer of potato slices over the tomatoes, overlapping them slightly like shingles to create an even layer. Spoon more stewed tomatoes over the potatoes, spreading them out so every slice gets some tomato and juice.
Repeat layering potatoes and stewed tomatoes until you’ve used all the ingredients, finishing with a generous layer of tomatoes on top. Pour any remaining tomato juices over the dish so the potatoes have plenty of liquid to cook in.
Cut the salted butter into small pieces and scatter them evenly over the top layer of tomatoes. As the casserole bakes, the butter will melt into the tomatoes and potatoes, adding richness and helping the edges brown.
Cover the baking dish tightly with foil and place it on the middle rack of the preheated oven. Bake for 45 minutes, until the potatoes are starting to turn tender when pierced with the tip of a knife.
Carefully remove the foil and continue baking, uncovered, for 25–35 minutes more, or until the potatoes are fully tender, the tomatoes are bubbling, and the edges are lightly browned and caramelized. The total baking time will be about 1 hour 10 minutes to 1 hour 20 minutes, depending on how thick your potato slices are.
Let the dish rest for at least 10 minutes out of the oven before serving. This brief rest allows the layers to settle and makes it easier to scoop neat portions. Serve warm straight from the glass baking dish.
Variations & Tips
Because this recipe is intentionally built around just three ingredients, I like to treat any extras as optional upgrades rather than requirements. If you want to stay close to the spirit of the original church-potluck version, keep it simple and resist the urge to overcomplicate it. That said, there are a few directions you can go. For seasoning without adding new ingredients, choose stewed tomatoes that already include herbs, onions, or celery; many brands label them as Italian-style or with green peppers, and they’ll quietly layer in more flavor. You can also play with texture by changing the potato: Yukon Golds give a creamier, almost buttery texture, while russets break down a bit more and make the dish looser and more saucy. For a slightly richer top, dot the finished bake with a little extra butter right when it comes out of the oven and let it melt over the browned tomatoes. If you’re serving a crowd, this doubles easily in two pans; just be sure not to stack the layers too deep or the potatoes will take longer to soften. Leftovers reheat well, covered, in a 350°F (175°C) oven until warmed through, and the flavors often deepen by the next day.
