My grandma used to make this growing up and it is unbelievably creamy. You won't believe this comforting dish only requires 3 ingredients.

This oven baked 3-ingredient evaporated milk potato bake is the kind of dish that shows up at every Midwestern family gathering and disappears almost as quickly as it hits the table. My grandma made a version of this when I was growing up, long before “minimal ingredient cooking” was trendy, and it was always unbelievably creamy despite its simplicity. Thinly sliced potatoes are layered with evaporated milk and just enough salt to coax out their natural flavor, then baked until the top is golden and the edges are bubbling with a rich, velvety sauce. It’s a practical, budget-friendly recipe that feels comforting and nostalgic, yet it fits neatly into a modern weeknight rotation.

Serve this potato bake as a cozy side dish alongside simple roasted chicken, pork chops, or seared sausages. It pairs especially well with anything that has a bit of acidity, like a green salad dressed with a sharp vinaigrette or steamed green beans with lemon, to balance the richness of the creamy potatoes. For a meatless plate, I like to add a crisp mixed salad and some roasted vegetables so the potatoes can be the indulgent centerpiece without feeling too heavy.

Servings: 6

2 1/2 pounds russet or Yukon Gold potatoes, peeled and very thinly sliced

Preheat your oven to 375°F (190°C). Lightly grease a 2- to 2 1/2-quart baking dish (about 8x8-inch or similar size) with a bit of neutral oil or butter if you like, though it’s not required for the recipe to work.

Peel the potatoes, then slice them as thinly and evenly as you can, about 1/8 inch thick. A mandoline makes this fast and consistent, but a sharp knife and a steady hand work just fine. The thin slices are key to getting that tender, creamy texture without any extra ingredients.

Spread a thin, even layer of sliced potatoes over the bottom of the baking dish, overlapping them slightly like shingles. Sprinkle a small pinch of the salt evenly over this layer.

Continue layering: add more potatoes in an even layer, then sprinkle lightly with salt. Repeat until you’ve used all the potatoes and salt, finishing with a neat top layer of potatoes. Don’t worry if the layers aren’t perfect; just aim for relative evenness so everything cooks at the same rate.

Shake the can of evaporated milk well, then slowly pour it over the potatoes. Pour around the edges and across the surface so the milk seeps down into the layers. The liquid should come almost to the top layer of potatoes but not completely submerge them; the exposed top will brown and form that golden crust.

Cover the dish tightly with foil and place it on the middle rack of the preheated oven. Bake for 40 minutes, until the potatoes are starting to soften and the evaporated milk is hot and beginning to thicken.

Carefully remove the foil and return the dish to the oven, uncovered. Continue baking for 25 to 35 minutes, or until the top is deeply golden, the edges are bubbling, and a knife slides easily through the center with no resistance. The evaporated milk will have transformed into a thick, creamy sauce around the potatoes.

Remove the dish from the oven and let the potato bake rest for at least 10 to 15 minutes before serving. This short rest allows the sauce to settle and cling to the potatoes instead of running when you scoop it out. Taste a little of the top and add a tiny pinch more salt at the table if needed. Serve warm, spooning through the golden crust to reveal the creamy layers underneath.

Because this recipe is intentionally stripped down to three ingredients, the technique does a lot of the heavy lifting: thin slicing, tight layering, and a proper bake-and-rest are what give you that unbelievably creamy texture. Once you’ve made the base version a few times, you can gently bend the rules for your own kitchen. For slightly richer results, you can use a mix of russet and Yukon Gold potatoes; russets break down a bit more and thicken the sauce, while Yukon Golds stay velvety. If you’d like a hint of peppery bite without adding more ingredients to the bake itself, grind black pepper over each serving at the table. You can also adjust the salt level to your taste—keep in mind that evaporated milk is unsweetened but concentrated, so the flavor of the salt will come through clearly. For a make-ahead option, assemble the dish earlier in the day, cover, and refrigerate; bring it back toward room temperature while the oven heats, then bake as directed, adding a few extra minutes if it’s still quite cold. Leftovers reheat well, covered, in a low oven or in short bursts in the microwave; a splash of extra evaporated milk over the top before reheating will help restore the original creaminess if the potatoes have absorbed most of the sauce.
