These Slow Cooker scalloped potatoes are creamy, cheesy, and made with just four main ingredients. Thin-sliced Satina potatoes, heavy cream, sharp cheddar, and onion soup mix cook into an easy side dish with no oven needed. You’re going to love how simple they are for cookouts, holidays, or busy days.
Why You’ll Love It
- Just four main ingredients — potatoes, cream, cheddar, and onion soup mix keep prep simple.
- No oven needed — the Slow Cooker frees up valuable oven space.
- Creamy, cheesy layers — tender potatoes cook in a rich cream sauce with sharp cheddar.
- Feeds a crowd — makes enough for eight to ten servings as a side dish.
- Easy to prep ahead — slice the potatoes in advance and layer when ready.
Ingredient Notes
Thin-sliced Satina potatoes are the whole point here, so keep those slices thin and reasonably even. If some are paper-thin and some are chunky enough to build a retaining wall with, they won’t cook at the same pace. Uneven slices can be irritating.
Heavy cream gives these potatoes their rich, silky sauce. This is not the moment for skim milk or whatever sad carton is hanging around in the back of the fridge. Use heavy cream. We’re making scalloped potatoes, not trying to prove a point.
Sharp cheddar is my preference because it stands Up To all that cream and potato. Mild cheddar works fine for a gentler flavor or for anyone who thinks black pepper is “too spicy.” Mild cheddar will work, though sharp cheddar has more flavor.
As for the onion soup mix, use the standard packet from the grocery store. It brings seasoning without having to stand there measuring six different things while sunscreen is missing.
Ingredients
- Cooking spray or a thin layer of butter, for the Slow Cooker
- 3 pounds thin-sliced Satina potatoes
- 2 cups heavy cream
- 1 packet onion soup mix
- 2 cups shredded sharp cheddar cheese
Instructions
Lightly coat the inside of a 6-quart oval Slow Cooker with cooking spray or a thin layer of butter. Do not skip this, even if you’re feeling rebellious. Creamy potatoes have a way of welding themselves to the crock if you give them even half a chance.
In a large bowl, stir the 2 cups heavy cream and the packet of onion soup mix together until it’s well combined. It will smell stronger than the finished potatoes taste, so don’t let that worry you. The mixture may seem strong, but the finished potatoes will not.
Arrange a layer of the thin-sliced Satina potatoes across the bottom of the slow cooker, overlapping them slightly. Spoon a little of the cream mixture over the potatoes, then scatter on a handful of the shredded sharp cheddar. You do not need to make every layer museum-perfect. Nobody is handing out awards for potato geometry.
Continue layering potatoes, cream mixture, and cheddar until everything is used, finishing with cheddar on top. Gently press the layers down with the back of a spoon or your clean hand so the cream can work its way into the little spaces between the slices. Not aggressively—these are potatoes, not a grudge.
Cover the slow cooker and cook on low for 5 to 6 hours, until the potatoes are very tender and the sauce is bubbling around the edges. Try not to keep lifting the lid to check them. Every peek lets out heat and adds time, and then suddenly dinner is late and crackers start looking tempting.
If you’d like the top to set up a bit more, uncover the slow cooker during the last 20 to 30 minutes of cooking. It won’t turn crisp like an oven-baked casserole top, but it helps the surface look a little less, shall we say, relaxed.
Let the potatoes rest for 10 to 15 minutes before serving so the layers can settle and scoop more neatly. Skipping this step is fine, and they will still taste wonderful—just a little more like creamy potato landslide than tidy scalloped potatoes.
Variations
If your crowd is the kind that believes there is no such thing as too much cheese, you can add an extra cup of shredded cheddar over the top during the last 30 minutes of cooking. It’s a lovely version, admittedly, though it is not exactly subtle.
For a gentler flavor, mild cheddar works in place of sharp cheddar. That’s especially handy for younger eaters or those folks who prefer everything beige and emotionally nonthreatening. I said what I said.
Extra ingredients like garlic, herbs, or more seasonings are fine, but not necessarily better. Just busier. Sometimes a recipe earns its place because it doesn’t demand a lot from you. There’s enough noise in the world without interrogating a pan of potatoes.
If you want the portions to hold together more like a casserole, let the slow cooker sit a little longer before serving. And if you’re prepping ahead, slice the potatoes and keep them covered in cold water in the refrigerator for a few hours. Drain and pat them dry before layering, though. Extra water will thin the cream sauce, and then you’ll be annoyed.
Storage & Reheating
Leftovers keep in a covered container in the refrigerator for a few days. Three days is best, maybe four if they’ve been chilled promptly and kept covered.
To reheat, warm a portion gently in the microwave until hot, stirring or breaking it up a little if needed. The potatoes thicken as they sit, so they won’t look exactly like they did fresh from the slow cooker—but they still taste darn good. You can also reheat them covered in the oven if you have a larger amount, though then you’re back to using the oven, which sort of defeats the philosophy of avoiding unnecessary sweating.
A little scoop alongside leftover ham or a fried egg the next morning is especially good. It feels indulgent, but it still makes an easy meal.
Final Notes
There are recipes you make because they’re exciting, and then there are recipes you make because they make the day easier. These slow cooker scalloped potatoes are firmly in that second category, and I mean that as high praise.
They’re perfect for casual tables, paper napkins, and easy meals where the slow cooker does its steady little job while everything else carries on around it. That is comforting.
And when you finally lift the lid and see all that cream bubbling around the potatoes, the cheese melted over the top… well. Dinner is handled. At least one part of the day behaved itself.
