Ingredients
| Ingredient | Quantity |
| Russet or Yukon Gold potatoes, peeled and thinly sliced | 3 pounds (1.36 kg) |
| Shredded sharp cheddar cheese | 3 cups |
| Heavy cream | 2 cups |
| Dry onion soup mix | 1 packet (1 oz / 28 g) |
| Salt | To taste |
| Black pepper | To taste |
| Butter or nonstick cooking spray | For greasing |
Cheese option: You can replace some or all of the cheddar with Gruyère and Parmesan for a more sophisticated flavor.
Step-by-Step Instructions
Step 1 – Prepare the Slow Cooker
Lightly grease the inside of a 5- to 6-quart slow cooker with butter or nonstick cooking spray. This helps prevent the potatoes and cheese from sticking.
Step 2 – Prepare the Potatoes
Peel the potatoes and slice them into thin, even rounds approximately ⅛ inch thick.
Try to keep the slices consistent in thickness so they cook evenly.
Step 3 – Create the First Layer
Arrange half of the sliced potatoes in an even layer at the bottom of the slow cooker.
Sprinkle half of the shredded cheddar cheese over the potatoes.
Step 4 – Add the Remaining Layers
Arrange the remaining potato slices over the first layer.
Sprinkle the rest of the shredded cheese evenly over the top.
Step 5 – Prepare the Cream Sauce
In a medium mixing bowl, whisk together the heavy cream and dry onion soup mix until well combined.
Season with black pepper and a little salt if needed. Remember that the soup mix and cheese already contain sodium.
Step 6 – Add the Cream Mixture
Pour the seasoned cream mixture evenly over the layered potatoes and cheese.
Gently move the potatoes if necessary to help the cream reach the lower layers.
Step 7 – Slow Cook
Cover the slow cooker and cook until the potatoes are completely tender and the sauce has thickened.
- LOW: 5–6 hours.
- HIGH: 3–4 hours.
Cooking times may vary depending on the thickness of the potato slices and your slow cooker.
Step 8 – Rest and Serve
Once the potatoes are tender, turn off the slow cooker and let the dish rest for approximately 10 minutes.
This allows the creamy cheese sauce to settle and thicken slightly.
Serve warm and enjoy!
Best Tips for Perfect Cheesy Scalloped Potatoes
Slice the potatoes evenly to ensure they cook at the same rate. Yukon Gold potatoes provide a naturally buttery texture, while Russet potatoes create a softer, starchier result. For the best flavor, shred your own cheddar cheese instead of using pre-shredded cheese, which may contain anti-caking ingredients that affect melting.
Best Ingredient Options
Yukon Gold potatoes are ideal for a creamy texture, while Russet potatoes are excellent if you prefer softer, more tender layers. Sharp cheddar provides a bold cheese flavor, but Gruyère adds a delicious nutty taste. You can also use half-and-half instead of heavy cream for a lighter sauce, although the result will be less rich.
Recipe Variations
For a garlic version, add two minced garlic cloves to the cream mixture. If you enjoy extra cheesy potatoes, sprinkle another ½ cup of cheddar over the top during the final 20–30 minutes of cooking. You can also add sliced mushrooms, caramelized onions, or a little smoked paprika for extra flavor.
What to Serve With Cheesy Scalloped Potatoes
These creamy potatoes pair beautifully with roasted chicken, grilled beef steaks, baked salmon, meatballs, or roasted vegetables. They also make an excellent side dish for holiday dinners, Sunday family meals, and special celebrations.
Make-Ahead Instructions
You can peel and slice the potatoes ahead of time and keep them submerged in cold water in the refrigerator for up to 24 hours. Drain and dry them thoroughly before layering. You can also measure the cheese and prepare the cream mixture in advance to save time.
Storage Instructions
Allow leftover scalloped potatoes to cool slightly before transferring them into airtight food-storage containers.
Refrigerate within two hours of cooking and store for up to 3–4 days.
Reheating Instructions
For individual portions, microwave the potatoes in a microwave-safe dish until thoroughly heated.
For larger portions, transfer them to an oven-safe baking dish, cover with foil, and warm at 325°F (165°C) until hot throughout. Add a splash of cream or milk if the sauce has thickened too much.
Freezing Instructions
These potatoes can be frozen, although the cream sauce may change texture slightly after thawing.
Allow the dish to cool completely, divide it into freezer-safe portions, and freeze for up to 2 months for the best quality.
Thaw overnight in the refrigerator before reheating thoroughly.
Common Mistakes to Avoid
Cutting the potatoes into uneven slices can cause some pieces to remain firm while others become too soft. Avoid adding too much salt because the onion soup mix and cheddar are already salty. Don’t use too little cream, as the potatoes need enough moisture to cook properly. Finally, avoid lifting the slow cooker lid repeatedly because this releases heat and increases cooking time.

Frequently Asked Questions
Which potatoes are best for scalloped potatoes?
Yukon Gold potatoes are excellent because they hold their shape while becoming creamy and tender. Russet potatoes are another good choice if you prefer a softer texture.
Can I use milk instead of heavy cream?
Yes, but the sauce will be thinner and less rich. For a creamier result, use half-and-half or combine milk with a little cream.
Can I use a different cheese?
Absolutely! Gruyère, Monterey Jack, mozzarella, and Parmesan all work well. A combination of cheddar and Gruyère creates especially delicious flavor.
Why are my scalloped potatoes still hard?
The slices may be too thick, or your slow cooker may need additional cooking time. Continue cooking until a fork slides easily through the potatoes.
Can I prepare this recipe the night before?
You can prepare the ingredients ahead of time, but it is best to assemble and cook the potatoes shortly before serving to prevent discoloration and excess moisture.
How do I make the sauce thicker?
Allow the cooked potatoes to rest for about 10–15 minutes before serving. The starch released by the potatoes helps the cream sauce thicken naturally.
