This 4-ingredient oven baked diced potato dish is the kind of weeknight shortcut I lean on when the day gets away from me. Canned diced potatoes are a classic pantry staple in many Midwestern kitchens, and here they’re transformed with three simple “secret” additions: melted butter, a creamy yellow sauce base, and a blanket of shredded cheese. Everything bakes together in one dish until the potatoes are tender and the top is golden and bubbly. It’s practical, budget-friendly, and so satisfying that kids usually go back for seconds without realizing how easy it was to make.
Serve these creamy baked diced potatoes alongside roasted chicken, pork chops, or simple pan-seared sausages for a complete dinner. A crisp green salad or steamed green beans help balance the richness. They’re also a natural fit on a holiday table next to ham or turkey. If you’re cooking for brunch, pair them with scrambled eggs and fruit for a cozy, diner-style plate.
4-Ingredient Oven Baked Diced Potatoes
Servings: 4

Ingredients
2 (15-ounce) cans diced potatoes, drained well
1/3 cup salted butter, melted
3/4 cup condensed cream of chicken soup (or cream of mushroom), undiluted
1 cup shredded cheddar cheese (or any good melting yellow cheese)
Directions
Preheat your oven to 400°F (200°C). Lightly grease an 8x8-inch or similar oven-safe baking dish.
Open the canned diced potatoes and drain them very well in a colander. Shake off as much liquid as possible so the potatoes roast and the sauce thickens instead of turning watery.
Pour the drained diced potatoes into the prepared baking dish, spreading them into an even layer.
In a small bowl or measuring cup, whisk together the melted butter and condensed cream of chicken soup until you have a smooth, pale yellow mixture.
Pour the butter-and-soup mixture evenly over the potatoes in the baking dish. Use a spatula or spoon to gently stir and coat all the potatoes with the yellow sauce.
Sprinkle the shredded cheddar cheese evenly over the top of the sauced potatoes.
Bake, uncovered, in the preheated oven for 25 to 30 minutes, or until the potatoes are hot all the way through, the edges are bubbling, and the cheese on top is melted and lightly golden.
Let the dish rest for about 5 minutes before serving so the sauce can thicken slightly and the potatoes are easier to scoop.
Variations & Tips
For extra flavor without adding more ingredients, use a sharp cheddar or a blend of yellow cheeses, which gives more character and color to the top. You can substitute cream of mushroom or cream of celery soup for the cream of chicken if you prefer a vegetarian-friendly base (just be sure your soup is actually vegetarian, as some cream soups use chicken stock). If you’d like a bit of color and crunch, bake as directed and then broil for 1 to 2 minutes at the end, watching closely so the cheese browns but doesn’t burn. To stretch the dish for a crowd, double everything and use a 9x13-inch baking dish, adding a few extra minutes to the bake time if needed. For a slightly lighter version, reduce the butter to 1/4 cup and use a reduced-fat condensed soup and part-skim cheese, keeping in mind the texture may be a bit less rich. Food safety tips: Keep canned potatoes stored in a cool, dry pantry and never use cans that are bulging, rusted through, or badly dented, as that can indicate spoilage. Once opened, if the potatoes have an off smell or unusual color, discard them. After baking, refrigerate leftovers within 2 hours in a shallow container; they’ll keep safely for up to 3 to 4 days. Reheat thoroughly in the oven or microwave until steaming hot in the center before serving again.
