You can’t go wrong with this classic side! Pair it with your favorite meat, and watch everyone go back for seconds (or thirds!). Trust me, you’ll be happy you made extra! 😄
Key Ingredients & Substitutions
Potatoes: Yukon Gold potatoes are my favorite for their buttery flavor. Russets are also great but may become a bit mushy. If you’re in a pinch, use red potatoes for a slightly different but still delicious texture.
Butter and Flour: Using unsalted butter allows you to control the saltiness. If you’re looking for a dairy-free option, try using olive oil for the roux and a flour blend that suits your needs. coconut flour works but may alter the texture slightly.
Milk: Whole milk makes a creamy sauce, but if you want it richer, go for heavy cream. You can also use almond or soy milk for a lighter version, though the flavor will differ. Just ensure it’s unsweetened, so it doesn’t clash with the savory notes!
Cheese: Sharp cheddar adds a great kick, but feel free to switch it up. Gruyère or mozzarella would work nicely too. If you’re keeping it dairy-free, there are plenty of plant-based cheeses available that melt well.
How Do I Make Sure My Sauce Doesn’t Get Lumpy?
A common challenge when making the sauce is avoiding lumps. Here’s my simple rule: whisk continuously! Once you melt the butter, add the flour and cook it quickly without letting it brown. This creates a smooth roux.
- Whisk in the milk slowly and continuously, aiming for a steady stream. This helps incorporate the liquid without forming lumps.
- Keep the heat on medium, not too high, to avoid scorching your sauce.
- If you do end up with lumps, don’t panic! Blend it briefly with an immersion blender, or strain the sauce through a fine mesh sieve.

How Much Time Will You Need?
This scalloped potatoes recipe takes about 15 minutes of preparation time and around 1 hour of cooking time. You’ll have these creamy, cheesy layers in your oven and then just wait until they’re bubbly and golden!
Step-by-Step Instructions:
1. Preheat and Prepare
Start by preheating your oven to 375°F (190°C). While the oven warms up, lightly grease a baking dish that’s about 9×13 inches. This will help your potatoes cook evenly and prevent sticking.
2. Slice the Potatoes
Peel the potatoes and thinly slice them to about 1/8-inch thickness. Using a mandoline slicer can make this job quick and easy! The thinner they are, the better they will cook through.
3. Make the Sauce
In a medium saucepan, melt the butter over medium heat. Once melted, stir in the flour and cook for about 1-2 minutes, stirring constantly to create a roux without browning it. This step is crucial to ensure your sauce has a nice base.
4. Add the Milk
Gradually whisk in the milk, being careful to prevent any lumps. Continue cooking and stirring until the mixture thickens and starts to bubble, which should take about 5-7 minutes. The sauce should be smooth and creamy!
5. Season the Sauce
Now it’s time to add flavor! Season your sauce with salt, pepper, garlic powder (if you’re using it), and dried thyme. If you’re opting for cheddar cheese, stir it in now until it’s melted and everything is combined.
6. Layer the Potatoes and Sauce
In your greased baking dish, arrange a layer of sliced potatoes evenly across the bottom. Pour a portion of the creamy sauce over the potatoes, spreading it out to cover them. Repeat this process, layering the potatoes and sauce until you reach the top, making sure the last layer is sauce.
7. Add the Topping
To finish, sprinkle the grated Parmesan cheese generously over the top layer. This will create a beautiful, golden crust as it bakes!
8. Bake the Dish
Cover the dish with aluminum foil to trap the steam and help the potatoes cook through. Bake in the preheated oven for 40 minutes. Then, carefully remove the foil and continue baking for an additional 25-30 minutes, or until the potatoes are tender and the top is nicely browned and bubbly.
9. Let it Rest
Once done, remove the scalloped potatoes from the oven and let them rest for about 10 minutes. This allows the sauce to set a little, making it easier to serve. If desired, garnish with fresh or dried thyme sprigs for a nice touch.
Enjoy your creamy, cheesy scalloped potatoes with your favorite main dish!
Can I Use Other Types of Potatoes?
Absolutely! Yukon Gold and Russet are great choices, but you can also use red potatoes for a slightly different texture. Just make sure they are thinly sliced for even cooking!
How Do I Store Leftover Scalloped Potatoes?
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through, or in the microwave for quick reheating.
Can I Make This Recipe Ahead of Time?
Yes! You can prepare the potatoes and sauce a day in advance, layering them in the dish and covering it. Just keep it refrigerated until you’re ready to bake it. You may need to add a few extra minutes to the baking time if it’s coming straight from the fridge.
What Can I Add for Extra Flavor?
In addition to cheddar cheese, you can mix in some cooked bacon or ham for a heartier dish. Fresh herbs like rosemary or chives can also enhance the flavor profile. Just sprinkle them between the layers!
