- 1 can condensed cream of mushroom soup, 10.5 ounces

How to Make Slow Cooker Creamy Mushroom Potatoes
Step 1: Prepare the Potatoes
Wash and peel the potatoes if desired.
Slice them thinly and as evenly as possible.
Even slices help the potatoes cook at the same rate.
Step 2: Prepare the Creamy Sauce
In a medium bowl, whisk together the cream of mushroom soup and milk.
Add garlic powder, black pepper, and salt.
Mix until smooth.
Step 3: Layer the Potatoes
Lightly grease the slow cooker with butter.
Arrange a layer of sliced potatoes across the bottom.
Add some sliced onion and a little shredded cheddar cheese.
Repeat the layers until the potatoes, onions, and cheese are used.
Step 4: Add the Mushroom Soup
Pour the cream of mushroom mixture evenly over the layered potatoes.
Try to distribute the sauce throughout the slow cooker rather than pouring it all in one spot.
Step 5: Add Butter
Dot the remaining butter over the top.
This adds extra richness as the potatoes cook.
Step 6: Slow Cook
Cover and cook on LOW for 5–6 hours, or until the potatoes are fork-tender.
Cooking time can vary depending on the thickness of the potato slices and your slow cooker.
Avoid lifting the lid too often because each opening releases heat.
Step 7: Finish With Cheese
During the final 15–20 minutes, sprinkle the remaining cheddar cheese over the top.
Cover and allow the cheese to melt.
Step 8: Serve
Once the potatoes are tender and the cheese is melted, carefully spoon them onto a serving dish.
Serve hot alongside your favorite main course.
What Do Creamy Mushroom Potatoes Taste Like?
These potatoes are creamy, savory, rich, and comforting.
The cream of mushroom soup creates a smooth sauce that coats the tender potato slices, while onions add extra savory flavor.
Melted cheddar gives the dish a delicious cheesy finish.
The result is similar to classic scalloped potatoes but with the convenience of a slow cooker.
Tips for the Best Slow Cooker Potatoes
Slice the Potatoes Evenly
Thin, uniform slices cook more evenly and help prevent some pieces from becoming overcooked while others remain firm.
Don’t Slice Them Too Thick
Very thick potato slices can require significantly more time to become tender.
Choose the Right Potatoes
Yukon Gold potatoes provide a naturally creamy texture.
Russet potatoes also work well and create a softer, starchier result.
Don’t Add Too Much Liquid
The potatoes release moisture while cooking.
Stick to the recommended amount of milk and soup to avoid an overly watery sauce.
Keep the Lid Closed
Slow cookers rely on trapped heat and moisture.
Opening the lid repeatedly can extend the cooking time.
Can I Use Russet Potatoes?
Yes.
Russet potatoes are an excellent choice and become soft and tender during slow cooking.
Yukon Gold potatoes are another great option if you prefer a creamier texture.
Can I Leave the Potato Skins On?
Yes.
If you prefer a more rustic side dish, wash the potatoes thoroughly and leave the skins on.
Can I Use Cream of Chicken Soup?
Yes.
Cream of chicken soup can replace cream of mushroom soup if that’s what you have available.
The flavor will be slightly different.
Can I Add More Cheese?
Absolutely.
Cheddar, Monterey Jack, or a cheddar blend can all work well.
Add extra cheese during the final part of cooking so it melts smoothly.
Can I Add Bacon?
Yes.
Cooked, crumbled bacon makes a delicious addition.
Sprinkle it over the potatoes just before serving.
Can I Add Mushrooms?
Definitely.
Fresh sliced mushrooms pair naturally with cream of mushroom soup and potatoes.
Add them between the potato layers.
Can I Add Garlic?
Yes.
Fresh minced garlic can be used instead of or in addition to garlic powder for a stronger garlic flavor.
Easy Variations
Cheesy Mushroom Potatoes
Add extra cheddar or Monterey Jack for a richer cheesy side dish.
Garlic Herb Potatoes
Add fresh garlic, thyme, and parsley.
Bacon Cheddar Potatoes
Add cooked crumbled bacon and extra cheddar cheese.
Loaded Slow Cooker Potatoes
Top the finished potatoes with green onions, sour cream, and cooked bacon.
Holiday Creamy Potatoes
Add a little fresh parsley before serving for a simple holiday presentation.

Try serving them with:
- 🍗 Roast chicken
- 🥩 Beef roast
- 🍖 Pork chops
- 🦃 Turkey
- 🥩 Steak
- 🍖 Meatloaf
- 🥦 Roasted vegetables
- 🥗 Green salad
They’re especially delicious alongside roast beef or a holiday turkey dinner.
Can I Make These Ahead of Time?
Yes.
You can prepare the potatoes and sauce ahead of time and refrigerate them until you’re ready to cook.
For the best texture, avoid leaving sliced raw potatoes submerged in water for extended periods.
How to Store Leftovers
Allow leftovers to cool promptly.
Transfer the potatoes to an airtight container and refrigerate within 2 hours.
Enjoy within 3–4 days.
How to Reheat
Reheat individual portions in the microwave or warm the potatoes gently in a covered oven-safe dish.
If the sauce has thickened, add a small splash of milk before reheating.
Can You Freeze Creamy Potatoes?
You can freeze them, but potatoes and creamy sauces may change texture after freezing and thawing.
For the best quality, these potatoes are better enjoyed fresh or refrigerated.
