Scalloped potatoes are creamy and cheesy layers of goodness baked to perfection! They are made with sliced potatoes, milk, cheese, and a sprinkle of spices for that extra oomph.
I’ll be honest, I could eat these every day! They pair perfectly with grilled meats or just as a cozy dish on their own. Plus, who doesn’t love a cheesy potato treat? 🥔🧀
Key Ingredients & Substitutions
Russet Potatoes: These are great for scalloped potatoes due to their starchy nature, which helps achieve a creamy texture. If you’re looking for a healthier option, you can use Yukon Gold potatoes; just know they’ll have a slightly different flavor and texture.
Butter: Unsalted butter is best, so you can control the salt. If you’re watching cholesterol, olive oil can be a good substitute, just note that it will change the flavor a bit.
Milk: Whole milk is my go-to for creaminess. However, half-and-half or cream will make it even richer, while low-fat milk can work if you prefer to cut calories. Just keep the taste in mind!
Cheese: Sharp cheddar adds wonderful flavor, but mixing in Gruyere or mozzarella can elevate the dish further. If you’re lactose intolerant, try using a lactose-free cheese!
Seasonings: Garlic powder adds great depth, but for a fresh flavor, consider using minced garlic instead. Nutmeg is optional but adds a lovely warmth; use it for a special touch!
How Do I Ensure My Potatoes Are Cooked Perfectly?
The key to perfectly cooked scalloped potatoes is all in the slicing and layering. Aim for uniform slices about 1/8 inch thick. A mandoline slicer is very helpful here. Also, don’t skip resting the dish after baking. This helps the sauce thicken and flavors settle!
- Start by layering the potatoes in the buttered dish, overlapping slightly for even cooking.
- Pour sauce over each layer, ensuring it’s evenly distributed.
- Cover with foil to trap steam, then remove it for a crispy top.
- Allow resting time after baking; it makes slicing much easier!
How to Make Delicious Scalloped Potatoes
Ingredients You’ll Need:
For the Dish:
- 3 pounds russet potatoes, peeled and thinly sliced
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 3 cups whole milk (or half-and-half for a creamier texture)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/4 teaspoon ground nutmeg (optional)
- 2 cups shredded sharp cheddar cheese (you can mix this with Gruyere for extra richness)
- Fresh thyme for garnish (optional)
How Much Time Will You Need?
This recipe will take about 15 minutes to prep and 1 hour and 10 minutes to bake. After baking, let the dish rest for about 10 minutes before serving, making the total time around 1 hour and 35 minutes. It’s a perfect dish to make ahead for a cozy dinner!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). Prepare a 9×13-inch baking dish by buttering it to prevent sticking.
2. Prepare the Potatoes:
Peel the russet potatoes and slice them very thin, about 1/8 inch thick. A mandoline slicer is great for uniform slices, but a sharp knife works too. Try to keep the slices even for even cooking.
3. Make the Cheese Sauce:
In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes, stirring constantly to create a roux. Gradually whisk in the milk, ensuring the mixture stays smooth and lump-free. Keep stirring until the sauce thickens and can coat the back of a spoon, about 5 minutes.
4. Season the Sauce:
Add the salt, pepper, garlic powder, and nutmeg (if using) to the sauce. Remove the saucepan from heat, then stir in 1 1/2 cups of cheese until it melts and becomes smooth.
5. Layer the Potatoes:
Arrange a layer of potato slices at the bottom of the buttered dish. Pour a portion of the cheese sauce over the layered potatoes to cover them. Repeat this layering until all potatoes and sauce are used, finishing with a layer of sauce on top.
6. Add the Final Touch:
Sprinkle the remaining 1/2 cup of cheese evenly over the top layer of sauce.
7. Bake the Dish:
Cover the dish tightly with aluminum foil and bake it in the preheated oven for 45 minutes. After that, remove the foil and bake for an additional 25-30 minutes, or until the potatoes are tender and the top is golden brown and bubbly.
8. Rest and Serve:
Once baked, let the scalloped potatoes rest for about 10 minutes before serving. This helps the layers settle. Garnish with fresh thyme if you like, and enjoy your creamy, cheesy, and comforting dish!
Can I Use a Different Type of Cheese?
Absolutely! While sharp cheddar is a classic choice, you can mix it up with cheeses like Gruyere for extra richness or mozzarella for a milder flavor. Just keep the total cheese amount similar to maintain creaminess.
Can I Prepare This Dish in Advance?
Yes, you can prepare scalloped potatoes a day ahead! Assemble everything up to the baking step, cover it tightly with foil, and refrigerate. When you’re ready to bake, add a few extra minutes to the cooking time to ensure it’s heated through.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, pop them in the oven at 350°F (175°C) until warmed through, or microwave them in individual portions for convenience.
Can I Use Dairy-Free Alternatives?
Certainly! You can use almond milk, coconut milk, or any other dairy-free milk, along with plant-based butter and cheese to create a lactose-free version. Just be mindful that flavor and creaminess may vary slightly!
