Scatter crushed plain potato chips over raw sliced russet potatoes, alongside 2 simple ingredients, into a glass casserole dish for a cozy family meal that’s always a yes in my house

This cozy Amish-style potato chip casserole is what I reach for on those nights when I’m tired from work but still want something warm and comforting on the table. It’s a simple, four-ingredient, oven-baked dish that layers raw sliced russet potatoes with a creamy sauce and a generous blanket of crushed plain potato chips. Everything gets scattered right into a glass casserole dish, then baked until the potatoes are tender and the chips on top are golden and crisp. It feels like something your grandma might have made, but with the kind of ease that fits into a busy weeknight.

I like to serve this casserole with something fresh and simple on the side, like a green salad with a tangy vinaigrette or steamed green beans to balance the richness. It also pairs really well with roasted or grilled chicken, pork chops, or even just a pile of scrambled eggs if we’re doing breakfast-for-dinner. Add a side of applesauce or sliced fresh fruit to keep it feeling homey and family-style.

Servings: 6

2 tablespoons unsalted butter, softened (for greasing the glass casserole dish)

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch glass casserole dish with the softened butter, making sure to get into the corners so the potatoes don’t stick.

Peel the russet potatoes and slice them into thin rounds, about 1/8 inch thick. You can use a sharp knife or a mandoline if you have one. Try to keep the slices roughly the same thickness so they cook evenly.

In a medium bowl, stir the sour cream until smooth. You don’t need to season it; the potato chips will add plenty of salt and flavor.

Spread half of the raw sliced potatoes in an even layer in the bottom of the buttered glass casserole dish, slightly overlapping the slices like shingles.

Dollop half of the sour cream over the potatoes, then gently spread it with the back of a spoon or a spatula so it covers most of the surface. It doesn’t have to be perfect; it will melt and spread more as it bakes.

Take half of the plain potato chips and crush them lightly with your hands right over the dish, scattering the pieces evenly over the sour cream and potato layer. Aim for bite-sized pieces, not crumbs, so you still get some crunch.

Repeat the layers: add the remaining sliced potatoes in an even layer, spread the rest of the sour cream over the top, and then scatter the remaining crushed plain potato chips over everything, crushing them with your hands directly over the casserole so they form a loose, crunchy topping.

Cover the glass casserole dish tightly with aluminum foil. Bake on the center rack for 45 minutes, until the potatoes are starting to turn tender when pierced with a fork.

Remove the foil and continue baking for another 20–25 minutes, or until the potatoes are fully tender and the potato chip topping is golden brown and crisp. If the chips start to get too dark near the end, you can loosely tent the dish with foil again.

Let the casserole rest for 10–15 minutes before serving. This helps the layers set up a bit and makes it easier to scoop out neat portions.

You can tweak this simple casserole a few different ways while still keeping the spirit of the recipe. For a little extra flavor without adding more ingredients, use a thicker, kettle-style plain chip for more crunch, or switch to a lightly salted chip if you’re watching sodium. If you want a bit more richness, dot the top of the sour cream layer with a few extra small pieces of butter before scattering the chips. To stretch the meal, serve it alongside leftover rotisserie chicken or fold in a cup of finely diced cooked ham or bacon between the potato layers (just be aware this makes it more than four ingredients, if you’re counting). For a slightly lighter version, you can swap half of the sour cream for plain Greek yogurt, though the sauce will be a bit tangier and less rich. Food safety tips: Always wash and dry the potatoes before peeling and slicing to remove any dirt. Use a sharp knife or mandoline carefully and keep your fingers tucked back to avoid cuts. Because this casserole contains dairy, refrigerate leftovers within 2 hours of baking, store in a covered container, and reheat thoroughly in the oven or microwave until steaming hot before eating. Discard any leftovers that have been left at room temperature too long or show any off smells or signs of spoilage.
