Ingredients
6 large potatoes
Potatoes are the heart of this recipe. Choose potatoes that hold their shape reasonably well during slow cooking. Slice them thinly and evenly so they cook at approximately the same rate.
1 packet Lipton Onion Soup Mix
This is the secret to the recipe’s distinctive flavor. The dehydrated onions and seasonings provide a concentrated savory onion taste without requiring you to chop and sauté onions separately.
1/3 cup butter, melted
Butter coats the potatoes and contributes rich, comforting flavor. Melting it first makes it much easier to distribute evenly over the potato slices.
1 cup shredded cheddar cheese, optional
Cheddar isn’t essential, but it turns the potatoes into an especially indulgent side dish. For the best texture, shred the cheese yourself if possible.
1/2 cup chicken broth or water
A small amount of liquid helps create moisture inside the slow cooker, allowing the potatoes to cook gently and become tender without drying out.
Salt and black pepper, to taste
The soup mix already contains seasoning, so use additional salt sparingly. Freshly ground black pepper adds a simple finishing touch.
Cooking spray or butter
Use this to grease the slow cooker before adding the potatoes. It helps minimize sticking and makes cleanup easier.
How to Make Slow Cooker Lipton Onion Potatoes
Step 1: Prepare the slow cooker
Generously coat the inside of your slow cooker with cooking spray or butter. This helps prevent the potatoes from sticking to the sides and bottom during cooking.
Step 2: Slice the potatoes
Wash the potatoes thoroughly. Peel them if you prefer peeled potatoes, or leave the skins on for a more rustic result.
Slice the potatoes into thin, even slices. Consistency is important because very thick slices may take longer to become tender while extremely thin slices can become overly soft.
Step 3: Add the butter and onion seasoning
Place the sliced potatoes in a large mixing bowl.
Pour the melted butter over the potatoes and gently toss until the slices are well coated.
Sprinkle the Lipton Onion Soup Mix over the potatoes and toss again, making sure the seasoning is distributed throughout.
Step 4: Add the optional cheese
If you’re making the cheesy version, add the shredded cheddar cheese and gently mix it through the potatoes.
For a stronger cheesy finish, you can also reserve some cheese to sprinkle over the potatoes near the end of cooking.
Step 5: Layer the potatoes
Transfer the seasoned potatoes to the prepared slow cooker.
Spread them out as evenly as possible, then pour 1/2 cup chicken broth or water over the top.
Don’t add excessive liquid—the potatoes will release moisture as they cook.
Step 6: Slow cook until tender
Cover the slow cooker and cook:
LOW: 5–6 hours
HIGH: 2–3 hours
Cooking time can vary depending on your slow cooker and the thickness of your potato slices. The potatoes are ready when they can be easily pierced with a fork.
Step 7: Taste and finish
Once tender, carefully taste the potatoes.
Add black pepper and additional salt only if needed, since the onion soup mix is already seasoned.
If you’ve reserved cheese for the top, sprinkle it over the potatoes during the final few minutes and allow it to melt.
Step 8: Serve hot
Spoon the potatoes onto a serving platter or serve them directly from the slow cooker.
For the best texture and flavor, enjoy them hot and fresh.
Pro Tips for Perfect Slow Cooker Onion Potatoes
Slice evenly. This is one of the most important details. Uniform slices help the potatoes finish cooking at the same time.
Don’t drown the potatoes. You only need a small amount of broth or water. Too much liquid can make the finished potatoes watery.
Go easy on the salt. Onion soup mix is already quite flavorful, so taste before adding additional salt.
Don’t overcook. Start checking the potatoes toward the lower end of the suggested cooking time. Once fork-tender, they’re ready.
Try freshly shredded cheddar. It generally melts more smoothly than some pre-shredded varieties.
Want extra onion flavor? Add a small amount of thinly sliced fresh onion along with the potatoes.
For a richer finish, add a little extra butter just before serving.
Let the slow cooker do the work. Avoid repeatedly removing the lid because each opening releases accumulated heat and can extend the cooking time.

Easy Variations

Finish with chopped fresh parsley, chives, or thyme just before serving.
Loaded Slow Cooker Potatoes

Frequently Asked Questions
Can I leave the potato skins on?
Absolutely. Leaving the skins on gives the dish a rustic appearance and saves preparation time. Just wash and scrub the potatoes well before slicing.
Can I make these potatoes without cheese?
Yes. The cheddar is completely optional. The combination of potatoes, butter, and onion soup mix provides plenty of flavor on its own.
Can I use water instead of chicken broth?
Yes. Chicken broth adds extra savory flavor, but water works perfectly well when that’s what you have available.
How do I know when they’re done?
Insert a fork into a few potato slices. They should be tender and easy to pierce without completely falling apart.
Can I prepare these ahead of time?
You can wash and slice the potatoes ahead of time, but for the best results, prepare and cook them relatively soon afterward. If you need to hold sliced potatoes briefly, keep them covered in cold water to reduce browning, then drain and dry them well before continuing.
