Scalloped potatoes are a creamy, cheesy delight that will warm your heart! Layers of tender potatoes are baked with a rich sauce until they’re golden and bubbling.
They’re perfect for family dinners or cozy get-togethers. Whenever I make them, I can’t resist sneaking a taste right from the dish. Who can blame me, right? 😄
I love that scalloped potatoes are easy to make. Just slice, layer, pour the sauce, and bake! It’s a comforting side dish that everyone enjoys. Yum!
Key Ingredients & Substitutions
Potatoes: Yukon Gold or Russet potatoes are great for this dish. Yukon Gold is buttery and smooth, while Russets are fluffy. If you want to try something different, sweet potatoes work beautifully too!
Milk & Cream: Whole milk and heavy cream create a rich sauce. If you’re looking for lighter options, you can use half-and-half or evaporated milk. For a dairy-free version, try almond or oat milk with coconut cream.
Butter: Unsalted butter is ideal for controlling the saltiness of your dish. You can substitute olive oil or even vegan butter for a dairy-free option.
Cheese: Sharp cheddar adds a nice flavor kick, but feel free to mix it up with gruyère or mozzarella for a different taste. If you’re avoiding dairy, try nutritional yeast for a cheesy flavor without the creaminess.
Garlic and Onion: Fresh garlic and onion bring depth to the dish. In a pinch, onion powder and garlic powder can work as substitutes, but fresh is always best for flavor.
What’s the Best Way to Make a Smooth Sauce?
Creating a smooth sauce is crucial for scalloped potatoes. Start by melting the butter and adding onion and garlic until soft. Then, sprinkle in flour to form a roux. Keep whisking for about 1-2 minutes to cook the flour without browning it.
- Gradually whisk in the milk and cream while stirring constantly. This prevents lumps from forming.
- Continue to whisk until the sauce thickens, which should take about 5-7 minutes. If lumps appear, you can blend the mixture with a hand mixer or remove any stubborn lumps before proceeding.

- 2 cups whole milk
- 1 cup heavy cream
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 teaspoon salt

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and 1 hour of baking time for a total of 1 hour and 15 minutes. You’ll have creamy, warm scalloped potatoes ready to enjoy!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 375°F (190°C). While it’s heating up, take a moment to grease a baking dish with a bit of butter to prevent the potatoes from sticking.
2. Cook the Onion and Garlic:
In a medium saucepan, melt the unsalted butter over medium heat. Once melted, add in the chopped onion and minced garlic. Sauté them together for about 3-4 minutes until they become translucent and fragrant. This will create a lovely base flavor for your sauce.
3. Make the Roux:
Sprinkle the all-purpose flour into the saucepan with the onion and garlic. Using a whisk, mix it continuously for about 1-2 minutes to create a roux. Be careful not to let it brown; it should just bubble lightly.
4. Prepare the Sauce:
Next, gradually whisk in the whole milk and heavy cream, stirring constantly. Keep whisking until the sauce becomes thick and smooth, which should take about 5-7 minutes. It’s okay if it’s bubbling a little as it thickens.
5. Season the Sauce:
Now stir in the salt, black pepper, and dried thyme into your sauce. If you’re using cheddar cheese, add in half now and stir until it melts into the sauce. Remove the saucepan from the heat.
6. Layer the Potatoes:
In your greased baking dish, arrange half of the thinly sliced potatoes in an even layer. Pour half of your creamy sauce over this layer. Make sure it’s spread evenly!
7. Repeat the Layers:
Now, repeat the process with the remaining potatoes and sauce. Top the whole dish with the rest of the cheddar cheese and sprinkle the grated Parmesan evenly over the top for an extra cheesy finish!
8. Bake Covered:
Cover your baking dish with foil, making sure it’s tightly sealed, and place it in the preheated oven. Bake for 45 minutes. This helps the potatoes cook through nicely.
9. Final Bake:
After the first baking period, remove the foil. Continue baking for an additional 20-25 minutes, or until the potatoes are tender and the top is beautifully golden brown and bubbling.
10. Serve and Enjoy:
Once it’s finished baking, let your scalloped potatoes cool for about 5-10 minutes before serving. If you like, garnish with fresh thyme sprigs for a lovely touch. Enjoy your delicious, creamy dish!
Can I Make This Recipe Without Heavy Cream?
Yes, you can omit heavy cream and use additional whole milk for a lighter version. If you want to maintain some creaminess, try using half-and-half or a non-dairy alternative like coconut cream.
How Should I Store Leftovers?
Leftover scalloped potatoes can be stored in an airtight container in the fridge for up to 3 days. To reheat, place them in the oven at 350°F (175°C) until warmed through, about 15-20 minutes.
Can I Add Other Vegetables?
Absolutely! Feel free to layer in some cooked broccoli, spinach, or mushrooms for added flavor and nutrition. Just make sure any added veggies are pre-cooked to ensure they heat through properly.
Can I Use Different Types of Cheese?
Yes! While sharp cheddar is delicious, you can substitute it with other cheeses like Gruyère, mozzarella, or a cheese blend. Just keep in mind that the flavor and texture will vary with each type.
