Key Ingredients & Substitutions
Potatoes: Russet potatoes are great for this dish due to their starchiness, which makes them creamy. If you want a waxy texture, Yukon Golds can be a good substitute.
Cheese: Sharp cheddar gives a punchy flavor. I also like adding mozzarella for extra stretchiness. If you don’t have these cheeses, try gouda or pepper jack for a different twist.
Milk & Cream: Whole milk and heavy cream create a rich sauce. You can use half-and-half or even almond milk as lighter alternatives, but the texture may slightly differ.
Butter & Flour: These are used to make a roux for thickening. If you need a dairy-free option, consider using olive oil and a gluten-free flour blend instead.
Seasonings: Garlic and onion add depth. If you’re short on time, garlic powder and onion powder work fine. Fresh herbs can also elevate the flavor.
How Do I Make the Perfect Cheese Sauce?
The cheese sauce is what makes scalloped potatoes truly special. Here’s how to master it:
- Start by melting butter in a saucepan over medium heat, then add minced garlic and onions (if using) until they smell great.
- Mix in flour to create a roux; whisk constantly for 1-2 minutes—don’t let it brown, or it can lose its tenderness.
- Gradually whisk in milk and cream, stirring continuously to avoid lumps. This step ensures the sauce is smooth.
- Cook until it thickens, about 5-7 minutes, then stir in your seasonings and cheese until melted.
Remember to keep the heat moderate; this helps the sauce develop its luxurious texture. Enjoy making this creamy sauce; it’s the heart of the dish!

How Much Time Will You Need?
This delicious cheesy scalloped potatoes bake will take about 20 minutes to prepare, and you’ll need an additional 1 hour for baking. Plan for a total of about 1 hour and 20 minutes until you can enjoy this creamy, cheesy dish!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 375°F (190°C). Grease a 9×13 inch baking dish (or a similar-sized casserole dish) with a bit of butter or oil to prevent sticking.
2. Prepare the Potatoes:
Next, peel the potatoes and slice them thinly, about 1/8 inch thick. A mandoline slicer is very handy for making uniform slices, but a sharp knife works fine too!
3. Make the Cheese Sauce:
In a medium saucepan, melt the butter over medium heat. Once it’s melted, add the minced garlic and chopped onion (if you’re using it). Sauté for about 2-3 minutes until it’s fragrant and the onion is translucent.
4. Create the Roux:
Sprinkle the flour into the saucepan and whisk it continuously for about 1-2 minutes. This will help form a roux – make sure it does not brown!
5. Add Milk and Cream:
Gradually pour in the whole milk and heavy cream while whisking continuously to prevent any lumps. Keep whisking for about 5-7 minutes until the sauce thickens up nicely.
6. Stir in Seasonings and Cheese:
Add the salt, pepper, dried thyme, and paprika (if you’re using it). Remove the saucepan from the heat and stir in 1 1/2 cups of shredded cheddar cheese until it’s melted and smooth. This is the magic sauce!
7. Layer the Potatoes:
Now, arrange half of the sliced potatoes in an even layer in your greased baking dish, then pour half of the creamy cheese sauce over the potatoes and spread it evenly.
8. Repeat the Layers:
Repeat this process with the remaining potatoes and pour the rest of the cheese sauce on top. Make it look nice and even!
9. Top with More Cheese:
Sprinkle the last 1/2 cup of cheddar cheese and the mozzarella cheese evenly over the top of your dish. Now it’s ready for the oven!
10. Bake:
Cover the baking dish with aluminum foil and bake in your preheated oven for 40 minutes. After that, remove the foil and continue baking for another 25-30 minutes until the top is golden brown and bubbly, and the potatoes are tender when pierced with a fork.
11. Let it Rest:
Once it’s out of the oven, let the scalloped potatoes sit for about 10 minutes to thicken up before you dig in.
12. Garnish and Serve:
Finish by garnishing your dish with fresh thyme sprigs for a pop of color and extra flavor. Serve warm and enjoy your creamy, cheesy scalloped potatoes with a beautifully golden crust!
Can I Use Different Types of Potatoes?
Yes, you can! While russet potatoes are ideal for their starch content, Yukon Golds work well too. They provide a creamy texture and hold their shape nicely.
Can I Prepare This Dish in Advance?
Absolutely! You can assemble the scalloped potatoes up to a day ahead. Just cover it tightly and store it in the refrigerator. Bake it straight from the fridge, but you may need to add a few extra minutes to the cooking time.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm them up in the oven or microwave, adding a splash of cream or milk to keep it creamy!
