Scalloped potatoes, in their various forms, have graced tables for centuries. While the exact origins are debated, similar potato gratins were popular in Europe as early as the 18th century. The beauty of this dish lies in its simplicity and adaptability. It’s a testament to how humble ingredients can be transformed into something truly extraordinary.
What makes a Cheesy Scalloped Potatoes Bake so irresistible? It’s the perfect marriage of textures the tender, yielding potatoes against the rich, velvety sauce. The cheesy element adds a savory depth that keeps you coming back for more. People adore this dish because it’s both comforting and satisfying, perfect for family gatherings, holiday feasts, or even a cozy weeknight dinner. Plus, it’s relatively easy to prepare, making it a winner in my book! So, let’s get started and create this classic dish together!
Ingredients:
- 5 pounds Yukon Gold potatoes, peeled and thinly sliced (about 1/8 inch thick)
- 1 large yellow onion, thinly sliced
- 6 tablespoons unsalted butter
- 6 tablespoons all-purpose flour
- 4 cups whole milk
- 1 teaspoon salt, plus more to taste
- 1/2 teaspoon black pepper, plus more to taste
- 1/4 teaspoon ground nutmeg
- 2 cups (8 ounces) shredded sharp cheddar cheese, divided
- 1 cup (4 ounces) shredded Gruyere cheese, divided
- 1/2 cup grated Parmesan cheese
- 1/4 cup chopped fresh parsley, for garnish (optional)
Preparing the Potatoes and Onions:
Okay, let’s get started! The key to a truly amazing scalloped potato bake is even slicing. I prefer Yukon Gold potatoes because they have a naturally creamy texture, but Russets will also work in a pinch. Just be sure to peel them well!
- Slice the potatoes: Using a mandoline or a very sharp knife, thinly slice the potatoes to about 1/8 inch thickness. Aim for uniformity so they cook evenly. If you’re using a knife, take your time! Uneven slices can lead to some potatoes being undercooked while others are mushy.
- Slice the onion: Thinly slice the large yellow onion. The onion adds a subtle sweetness and depth of flavor to the dish, so don’t skip it!
- Preheat the oven: Preheat your oven to 350°F (175°C). This lower temperature allows the potatoes to cook through completely without burning the cheese on top.
Making the Cheese Sauce:
Now for the star of the show the creamy, cheesy sauce! This is where the magic happens. Don’t be tempted to use pre-shredded cheese for this; freshly grated cheese melts much better and gives you a smoother, more flavorful sauce. Trust me, it’s worth the extra effort!
- Melt the butter: In a large saucepan over medium heat, melt the butter. Make sure the butter is completely melted before moving on to the next step.
- Whisk in the flour: Whisk in the flour and cook for 1-2 minutes, stirring constantly. This creates a roux, which will thicken the sauce. Be sure to cook the roux long enough to cook out the raw flour taste, but don’t let it brown.
- Gradually add the milk: Gradually whisk in the milk, a little at a time, until smooth. Whisk constantly to prevent lumps from forming. If you do get a few lumps, don’t panic! Just keep whisking vigorously, and they should eventually disappear.
- Simmer the sauce: Bring the sauce to a simmer, stirring constantly, and cook for 5-7 minutes, or until thickened. The sauce should be thick enough to coat the back of a spoon.
- Season the sauce: Stir in the salt, pepper, and nutmeg. Taste and adjust seasonings as needed. Remember, you can always add more salt and pepper, but you can’t take it away!
- Add the cheese: Remove the saucepan from the heat and stir in 1 1/2 cups of the cheddar cheese, 1/2 cup of the Gruyere cheese, and the Parmesan cheese until melted and smooth. Reserve the remaining cheddar and Gruyere for topping.
Assembling the Scalloped Potatoes:
This is where we bring it all together! Layering is key to ensuring that every bite is packed with flavor and cheesy goodness. I like to use a 9×13 inch baking dish, but any similar-sized dish will work.
- Grease the baking dish: Lightly grease a 9×13 inch baking dish with butter or cooking spray. This will prevent the potatoes from sticking to the bottom of the dish.
- Layer the potatoes and onions: Arrange a layer of potato slices on the bottom of the dish, overlapping slightly. Top with a layer of sliced onions.
- Pour sauce over the layers: Pour about one-third of the cheese sauce over the potatoes and onions, making sure to distribute it evenly.
- Repeat the layers: Repeat the layers of potatoes, onions, and cheese sauce two more times, ending with a layer of cheese sauce.
- Top with cheese: Sprinkle the remaining cheddar and Gruyere cheese evenly over the top of the potatoes. This will create a beautiful, golden-brown crust.
Baking the Scalloped Potatoes:
Now it’s time to let the oven work its magic! Baking time can vary depending on your oven, so keep an eye on the potatoes and check for doneness with a fork.
- Cover and bake: Cover the baking dish with aluminum foil and bake for 1 hour. Covering the dish prevents the top from browning too quickly and allows the potatoes to cook through evenly.
- Uncover and bake: Remove the foil and bake for another 30-45 minutes, or until the potatoes are tender and the cheese is melted and bubbly and golden brown. A fork should easily pierce the potatoes when they are done. If the top is browning too quickly, you can loosely tent it with foil.
- Let it rest: Let the scalloped potatoes rest for 10-15 minutes before serving. This allows the sauce to thicken slightly and makes it easier to slice.
Serving and Storing:
Finally, the moment we’ve all been waiting for! Garnish with fresh parsley for a pop of color and flavor, and serve hot. These scalloped potatoes are delicious on their own or as a side dish to your favorite main course.
- Garnish (optional): Garnish with chopped fresh parsley, if desired.
- Serve: Serve hot and enjoy!
- Store leftovers: Store any leftover scalloped potatoes in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.
Tips for Success:
- Use a mandoline: A mandoline makes slicing the potatoes much easier and ensures even thickness.
- Freshly grated cheese: Always use freshly grated cheese for the best melting and flavor.
- Don’t overcook: Overcooked potatoes can become mushy, so keep an eye on them while they’re baking.
- Let it rest: Letting the potatoes rest before serving allows the sauce to thicken and makes them easier to slice.
Variations:
- Add ham or bacon: For a heartier dish, add diced ham or bacon to the layers of potatoes and onions.
- Use different cheeses: Experiment with different cheeses, such as Gouda, Monterey Jack, or Havarti.
- Add garlic: Add minced garlic to the sauce for extra flavor.
- Spice it up: Add a pinch of cayenne pepper to the sauce for a little heat.
