Key Ingredients & Substitutions
Russet Potatoes: These potatoes are starchy and great for holding their shape in this dish. If you prefer a waxy texture, Yukon golds can be a good substitute.
Cheese: Sharp cheddar adds a nice kick, while mozzarella keeps it creamy. You can swap cheddar for Gruyère or Colby for a different flavor. Vegan cheese can also work for a dairy-free option.
Milk & Heavy Cream: Whole milk creates a rich sauce, but you can use 2% milk if you’re looking to reduce calories. For a dairy-free alternative, consider almond milk combined with coconut cream.
Butter & Flour: Using unsalted butter allows you to control the salt level. If you’re avoiding gluten, try using a gluten-free blend or cornstarch to create your roux.
How Do I Make the Creamy Cheese Sauce Without Lumps?
The key to a smooth cheese sauce lies in making the roux properly. First, melt the butter over medium heat and whisk in the flour, cooking for about 1-2 minutes. This step cooks off the raw flour taste and adds thickness.
- Be sure to whisk constantly when slowly adding milk and cream. This helps to prevent lumps.
- Continue whisking until the sauce thickens and covers the back of a spoon.
- Once off heat, mix in cheese until melted for a smooth finish.

- 1 small onion, finely chopped (optional)
- 2 cups shredded sharp cheddar cheese
- 2 cups shredded mozzarella cheese or a cheese blend

How Much Time Will You Need?
This delicious dish takes approximately 15 minutes of prep time. You’ll then let it cook in the slow cooker—about 6 to 7 hours on low or 3 to 4 hours on high—until the potatoes are tender and the cheese sauce is bubbly. It’s a great make-ahead side for any meal!
Step-by-Step Instructions:
1. Prepare Your Slow Cooker:
Start by greasing the inside of your slow cooker with butter or non-stick spray. This will help prevent the potatoes from sticking as they cook. A well-prepped slow cooker ensures everything comes out smoothly!
2. Make the Creamy Cheese Sauce:
In a medium saucepan, melt the butter over medium heat. Once melted, add the flour and whisk it in. Cook for about 1-2 minutes until the mixture is lightly golden and becomes a roux. This helps thicken the sauce!
Now, slowly whisk in the milk and heavy cream, making sure to avoid lumps. Keep whisking for 5-7 minutes until the mixture thickens enough to coat the back of a spoon. Remove from heat and stir in garlic powder, onion powder, salt, pepper, and half of the shredded cheese until everything is melted and smooth. Set this yummy sauce aside!
3. Layer the Potatoes and Cheese Sauce:
Take half of your sliced potatoes and layer them in the bottom of the slow cooker. If you’re using onion, sprinkle half of it over the potatoes. Next, pour half of your creamy cheese sauce evenly over this layer. It’s gonna be good!
Repeat the layering process with the remaining potato slices, onions, and cheese sauce.
4. Cook the Scalloped Potatoes:
Now cover the slow cooker and let the magic happen! Cook on low for 6-7 hours or on high for 3-4 hours until the potatoes are tender and the sauce is bubbly. Your kitchen will smell amazing!
5. Add More Cheese and Garnish:
About 15 minutes before you’re ready to serve, sprinkle the remaining cheese on top of your scalloped potatoes. Cover again to let the cheese melt. Finally, garnish with chopped fresh parsley before serving for a lovely touch!
6. Serve and Enjoy!
Now, it’s time to dish it up! Serve warm as a comforting side dish alongside your favorite proteins or roasted veggies. Your guests (and family) will love this creamy, cheesy delight!
This slow cooker method makes scalloped potatoes irresistibly creamy with perfectly tender slices, bursting with cheesy goodness, perfect for any meal. Enjoy!
Can I Use Other Types of Potatoes?
Yes! While russet potatoes are ideal for their starchiness, you can use Yukon gold potatoes for a creamier texture. Just ensure they are thinly sliced for even cooking.
What If I Don’t Have Heavy Cream?
No problem! You can substitute heavy cream with more whole milk for a lighter sauce. For a richer flavor, you could blend whole milk with a bit of sour cream or cream cheese.
Can I Make This Recipe Vegan?
Absolutely! Use vegan butter, plant-based cheese, and almond or coconut milk in place of dairy ingredients. Just ensure your cheese is dairy-free for a fully vegan dish.
How Do I Store Leftovers?
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the microwave or on the stove, adding a splash of milk if it looks too thick.
