These Slow Cooker Scalloped Potatoes feature tender, warm potatoes in a creamy, rich, perfectly seasoned sauce. They are simple to make, and free up space in the oven for holiday dinners!
Slow Cooker Scalloped Potatoes
Slow Cooker Scalloped Potatoes are an easy side dish to make in the CrockPot (which frees up the oven for the main entree!). Warm, soft potato slices are swimming in a creamy, cheesy, rich sauce seasoned with onion, garlic, and fresh thyme.
True scalloped potatoes don't have cheese, but I simply couldn't resist. You could skip the cheese if you want to. I'll only judge you a little bit.
They make a beautiful addition to holiday tables, and they're always a crowd-pleasing favorite.
Which Potatoes Should I Use?
The most common types are Yukon gold or Russet. Yukon gold have soft skins are don't need to be peeled. They are waxy and hold their shape very well.
Russet potatoes have a thicker skin that will need to be peeled, and they are a little bit starchier and softer.
You can use either type, depending on preference or availabilty.
The Most Important Rule for this Recipe
The most important thing you can do to make sure this recipe turns out amazing is using a block of cheese and freshly grating it.
I was in a hurry and used pre-shredded cheese once. ONCE. It turned out pretty bad. It didn't melt all the way, and didn't look very appetizing.
Here's the deal. Pre-shredded cheese may be great for convenience, but won't work for recipes that the cheese has to melt into something (particularly if there's no roux involved). Pre-shredded cheese is coated in starch, usually potato starch to prevent sticking in the package. This starch prevents it from melting as smoothly (or at all, in my case) as freshly grated cheese. (Need proof? Check out my video. I tried to take a shortcut and use store shredded cheese, and it didn't melt at all. Compare to my gorgeous, melty delicious photos, and you can see the problem right away!)
So TL;DR, use freshly grated cheese! Trust me. It's necessary!
Can You Put Raw Potatoes in the Slow Cooker?
Yes, absolutely! A slow cooker will safely cook raw potatoes in these scalloped potatoes and in my slow cooker soup recipes also!
How Will I Know When the Potatoes are Done Cooking?
Nothing is worse than serving scalloped potatoes when they are too hard or too mushy. Start checking your potatoes at the 3 hour mark by poking them with a fork to check for fork-tenderness. If they are tender, they're done!
If they're still a little hard in the center, cover and check again in about 30 minutes.
Cook time will also depend on the thickness of your potatoes. Thicker potatoes will need longer to cook. Try using a mandoline for thinly and evenly sliced potatoes that will be perfectly cooked every time!
What to Serve with Slow Cooker Scalloped Potatoes
Slow Cooker Scalloped Potatoes will go nicely next to virtually any protein, including your holiday turkey or ham.
Slow Cooker Scalloped Potatoes Variations
Scalloped potatoes are a basic, delicately flavored dish that has so much potential for variation and creativity. Here are some ideas to try!
- Bacon: Sprinkle some crispy crumbled bacon on top in the last 30 minutes or so. I don't recommend mixing it into the sauce or it will be greasy.
- Ham: Ham can be mixed into the sauce or sprinkled on top.
- Sweet potatoes: Instead of white potatoes, you can also use sweet potatoes.
- Cheese: Use your favorites! Try gouda, gruyere, Swiss, smoked cheddar. Just make sure it's freshly shredded!
- Herbs: Try some different fresh herbs such as parsley, chives, or rosemary.
- Spicy: Add some fresh or jarred chopped jalapenos, green chiles, red pepper flakes, or even a few dashes of Tabasco to the cream sauce for an extra spicy kick.
