Scalloped Potatoes are a timeless, comforting dish that brings warmth and satisfaction to any meal. Perfectly sliced potatoes baked in a creamy, cheesy sauce make this side dish an irresistible favorite for family dinners, holidays, or even casual gatherings. The simplicity of the ingredients—potatoes, milk, butter, and cheese—belies the depth of flavor they deliver when combined. The golden, crispy edges contrast with the soft, velvety layers of potatoes, creating a texture that’s both hearty and luxurious. Whether served alongside roasted meats or as the star of a vegetarian meal, scalloped potatoes are a classic you’ll want to return to time and again.
Preheat the oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish to prevent sticking.
In a medium saucepan, melt the butter over medium heat. Add the chopped onion and sauté until softened and golden brown, about 5 minutes.
Stir in the flour to create a roux, cooking for about 2 minutes until it turns a light golden color.
Gradually whisk in the milk and cream, continuing to stir until the mixture thickens and becomes smooth. This should take about 5 minutes.
Once the sauce has thickened, remove it from the heat and stir in 1 ½ cups of shredded cheese, allowing it to melt completely. Season the sauce with salt and pepper to taste.
Layer half of the sliced potatoes evenly in the prepared baking dish. Pour half of the cheese sauce over the potatoes, spreading it evenly. Repeat the layering with the remaining potatoes and cheese sauce.
Cover the dish with aluminum foil and bake for 45 minutes. After 45 minutes, remove the foil and sprinkle the remaining ½ cup of cheese over the top. Bake uncovered for an additional 15 minutes or until the cheese is bubbly and the potatoes are tender.
Let the scalloped potatoes cool for about 10 minutes before serving. Garnish with fresh parsley for a pop of color and extra flavor.
For an extra layer of depth, consider adding a touch of garlic to the sauce. Minced garlic sautéed with the onions will infuse the dish with a subtle yet aromatic flavor that pairs beautifully with the creamy sauce. Additionally, you can substitute some of the cheddar with gruyère or parmesan for a more complex cheese flavor. These cheeses add a nuttier and richer profile, elevating the dish to new heights. Another idea is to include a layer of ham or cooked bacon between the potato slices for a hearty, protein-packed variation that’s perfect for brunch or a special occasion.
Scalloped potatoes are more than just a side dish—they’re a celebration of comfort food at its finest. The creamy, cheesy sauce, coupled with tender layers of potatoes, makes every bite a decadent experience. Whether you’re hosting a holiday feast or preparing a simple weeknight dinner, scalloped potatoes bring an air of elegance to the table. Best of all, they’re easy to customize to your taste, allowing for endless variations that will keep this classic dish feeling fresh and exciting. Try them with different cheeses, add some herbs, or toss in a bit of protein for a complete meal. With scalloped potatoes, you can never go wrong.
