Scalloped potatoes are a creamy and cheesy dish that feels like a warm hug for your tummy! Thin slices of potatoes are baked with milk, cheese, and a hint of garlic until golden and bubbly.
These potatoes are the perfect side dish for any meal. I love serving them with roasted chicken or steak, and they always steal the spotlight on my dinner table! 🥔❤️
Key Ingredients & Substitutions
Potatoes: Russet potatoes are ideal for scalloped potatoes because they’re starchy and creamy. Yukon Golds are also great, adding a buttery flavor. If you need gluten-free options, sweet potatoes can be a fun swap!
Milk/Cream: Whole milk gives a rich flavor, while heavy cream adds extra creaminess. You can substitute with milk alternatives like almond or oat milk, but ensure they’re unsweetened to avoid changing the flavor.
Cheese: Sharp cheddar cheese adds a delicious tang. If you’re looking for a different flavor, consider Gruyère or mozzarella. For a non-dairy option, try nutritional yeast for a cheesy taste without dairy.
Butter: Unsalted butter is used to create the roux. If you want to make it dairy-free, use olive oil or a plant-based butter alternative. Just keep in mind that the flavor will slightly differ.
Herbs: Fresh thyme or parsley gives a nice finish. If you don’t have fresh herbs, dried ones work too. Just use about a third of the amount, as dried herbs are more concentrated.
How Do You Make the Perfect Roux for Creamy Scalloped Potatoes?
Creating the roux is a key step for a smooth sauce. A roux is made by cooking equal parts of butter and flour, which helps thicken your sauce. Here’s how to do it right:
- Melt the butter in a saucepan over medium heat. Don’t let it brown!
- Whisk in the flour, stirring constantly for about 1-2 minutes. You want it to bubble a bit without turning color.
- Gradually add the milk or cream while continuously whisking to prevent lumps. This makes sure the sauce is creamy and smooth when ready.
This technique ensures that your scalloped potatoes come out perfectly creamy without any clumps!
How to Make Scalloped Potatoes
Ingredients You’ll Need:
For the Dish:
- 4 large potatoes (Russet or Yukon Gold), peeled and thinly sliced
- 2 cups whole milk or heavy cream
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups shredded sharp cheddar cheese (optional for cheesy version)
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Salt and freshly ground black pepper, to taste
- Fresh thyme or parsley for garnish (optional)
How Much Time Will You Need?
This recipe will take about 15-20 minutes to prepare, plus 1 hour of baking time. You will spend a few minutes slicing the potatoes and making the creamy sauce before layering everything together in the baking dish. A total of about 1 hour and 15-20 minutes is what you’ll need for perfectly scalloped potatoes, including resting time!
Step-by-Step Instructions:
1. Prepare Your Oven and Dish:
First, preheat your oven to 375°F (190°C). While that’s warming up, take a medium-sized baking dish and lightly grease it with butter or cooking spray. This will help prevent the potatoes from sticking.
2. Slice the Potatoes:
Peel your potatoes and slice them thinly, about 1/8 inch thick. Thin slices cook evenly, making your scalloped potatoes tender and delicious!
3. Make the Sauce:
In a medium saucepan, melt the butter over medium heat. Once the butter is melted, whisk in the flour and cook for about 1-2 minutes. This forms a roux, which thickens your sauce. Keep stirring to avoid lumps! Then, gradually whisk in the milk (or cream). Keep whisking for about 5-7 minutes, until the sauce thickens and starts to bubble gently. When it’s done, remove it from heat.
4. Season Your Sauce:
Next, stir in the garlic powder, onion powder, and season with salt and pepper. If you’re using cheese, stir in 1 1/2 cups of shredded cheese at this point until it’s melted and smooth.
5. Layer the Potatoes and Sauce:
Now it’s time to assemble! Start by arranging half of the sliced potatoes in an even layer at the bottom of the prepared baking dish. Pour half of the creamy sauce over the potatoes, spreading it evenly. Repeat this process with the remaining potatoes and sauce. If you like, sprinkle the remaining 1/2 cup of cheese on top for a delicious golden crust!
6. Bake the Potatoes:
Cover the dish tightly with aluminum foil and bake in the preheated oven for 40 minutes. After that, carefully remove the foil and bake for an additional 25-35 minutes. The potatoes should be tender, and the top should be golden brown and bubbly.
7. Let It Rest:
Once done, remove the dish from the oven and let it rest for 10 minutes. This helps the sauce thicken slightly, making it easier to serve.
8. Garnish and Serve:
Before serving, if you’d like, sprinkle some fresh thyme or parsley on top for a pop of color. Then, enjoy your creamy, golden scalloped potatoes while they’re warm!
Can I use different types of potatoes?
Absolutely! While Russet and Yukon Gold potatoes work best for their creamy texture, you can also use other types like red potatoes or even sweet potatoes for a unique flavor. Just be mindful that cooking times might vary slightly based on the type used.
Can I make gratin ahead of time?
Yes! You can prepare the scalloped potatoes a day ahead of time up to the baking step. Just cover the assembled dish tightly with plastic wrap and store it in the fridge. When ready to bake, add an extra 10 minutes to the cooking time as it will be colder from the fridge.
How should I store leftovers?
Leftover scalloped potatoes can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, just place them in the oven at 350°F (175°C) until heated through, or use the microwave for a quicker option.
Can I substitute the cheese for a dairy-free version?
Yes! You can use a dairy-free cheese substitute or nutritional yeast for flavor without the dairy. Just be sure to choose a product that melts well for the best result, or simply skip the cheese for a lighter version!
