Four ingredients, a Slow Cooker, and barely any effort — that’s all this creamy Amish-style potato dish takes. Baby potatoes simmer low and slow in evaporated milk and butter until the sauce turns velvety and rich, clinging to every bite. It’s the kind of humble, comforting side dish that disappears fast.
Why You’ll Love It
Only 4 ingredients — baby potatoes, evaporated milk, butter, and salt. That’s it.
Completely hands-off — no boiling, no draining, no standing at the stove. Set it and walk away.
The sauce makes itself — the potato starch mingles with the milk as it cooks, creating a silky, glossy coating you didn’t have to do anything special to achieve.
Versatile enough for any night — works as a simple weeknight side or dressed up a little for company.
Great leftovers — reheats beautifully the next day, sauce and all.
A Note on the Ingredients
The baby potatoes matter. I’ve tried this with larger Yukon golds cut into chunks and it’s not the same — the ratio of skin to interior changes, the texture is a little off, and they tend to get mushy at the edges before the center is fully tender. Little baby potatoes, the ones that come in those mesh bags, hold together beautifully. Leave the smaller ones whole; cut anything bigger than a golf ball in half.
The evaporated milk — not sweetened condensed milk, I have to say this because at least once a year someone makes that mistake and it’s a disaster — is what gives you the creaminess without adding heavy cream or making it feel like you’re eating something that should come with a warning label. It thickens as it cooks. Trust it.
Butter. Real butter, not the spread in the tub. The kind you cut off a stick. I use unsalted because I’d rather control the salt myself and I don’t fully trust how much is already in things.
Kosher salt. I don’t use table salt for much of anything anymore, haven’t for probably fifteen years. The texture, the way it dissolves — I don’t know. I just don’t.
Ingredients
2½ pounds small baby potatoes, scrubbed — leave them whole unless any are really big, then halve those
1 can (12 ounces) evaporated milk — not the sweetened kind, I will say it again
4 tablespoons unsalted butter, cut into little pieces
1½ teaspoons kosher salt, maybe a bit more at the end depending on your taste
Let’s Make It
Rinse the potatoes and scrub off any dirt. I dry them with an old dish towel I keep specifically for vegetables — it has a strawberry print on it that has faded to almost nothing after probably a decade of washing. Pat them dry and set them aside.
Take a little bit of butter — just a scrape, really — and grease the inside of your Slow Cooker. Or use cooking spray. I know some people are anti-spray and if that’s you, just use the butter. The point is to keep things from sticking and to make cleanup less of a production.
Put the potatoes in. They’ll sit snugly, maybe a little mounded in the middle — that’s fine, you don’t need a perfect single layer, just don’t pile them up three or four deep or the ones in the center won’t cook through evenly.
Scatter the butter pieces over the top. Sprinkle the salt over everything. Then pour the evaporated milk slowly over the whole pile, letting it work its way down into the gaps between the potatoes. They won’t be submerged — that’s on purpose, that’s right — because they’ll release some of their own moisture as they cook and the liquid level will rise a bit.
Put the lid on. Set it to LOW and leave it alone for four and a half to five and a half hours. Or HIGH for two and a half to three hours if you need it faster, though I prefer low and slow when I have the time. Don’t peek. I know that sounds like advice from a fortune cookie but genuinely, every time you lift the lid you’re adding minutes to the cook time and messing with the steam situation.
When the potatoes are tender — poke one with a fork and it should go in without any resistance — give everything a gentle stir from the bottom up. The sauce will have thickened and it’ll cling to the potatoes in this glossy, creamy way that’s deeply satisfying to look at. Taste it and add more salt if it needs it.
Then do something I find very difficult to do: let it sit on the warm setting for ten or fifteen minutes before you serve it. The sauce tightens up a little. It’s worth the wait.
Variations
The dish is so simple that even small additions feel significant, so I’d encourage you to try the base version at least once before you start tinkering.
That said — a half teaspoon of black pepper stirred in with the salt is lovely. Just gives it a little bite.
If you want to add cheese, stir in a small handful of shredded cheddar or grated Parmesan in the last ten minutes. It melts in and makes the sauce richer. I don’t always do this but it’s good when I do — especially with cheddar.
A version I tried once with sliced onions layered under the potatoes was actually quite good. The onions sort of dissolved into the sauce and gave everything this faint sweetness. I’d do that again. What I wouldn’t do again is the garlic powder version I attempted at some point — it turned oddly medicinal and I couldn’t figure out why. Fresh smashed garlic cloves would probably be fine; the powder was not.
Leftovers
They keep fine in the fridge for three days, maybe four if you’re not squeamish. The sauce will solidify a little when cold — it goes almost pudding-thick — but it loosens right back up when you reheat it gently. I do it on the stove over low heat with a tiny splash of milk or just microwave it covered for a couple of minutes. Either way.
I will say that I once forgot a container of these in the back of my fridge for longer than I’d like to admit and that was not the sauce tightening up, that was a different situation entirely, and I don’t need to say more about it.
A Few Last Things
Serve it alongside whatever protein you have. Roast Chicken, pork chops, a piece of baked ham — anything simple. It doesn’t need much competition. A green salad on the side, maybe some bread for the sauce.
If you want to make it a whole meal, lay some sliced hard-boiled eggs over the top of each serving. I have no idea why that combination works as well as it does but it does.
