Scalloped Potatoes – Creamy & Cheesy
Scalloped Potatoes feature thinly sliced potatoes in creamy garlic sauce.Layer with onions and cheddar cheese, then cover and bake for 30 minutes.Uncover and bake until tender, bubbly, and golden brown.
Ingredients
- - 3 tablespoons unsalted butter plus more for greasing
- - ¼ cup all-purpose flour
- - 2 cups whole milk
- - 1 cup vegetable broth
- - 4 garlic cloves grated
- - 1 tablespoon fresh thyme leaves chopped
- - 2 teaspoons sea salt
- - ½ teaspoon freshly ground black pepper
- - 3 pounds Yukon Gold potatoes sliced ⅛-inch thick
- - ½ medium yellow onion thinly sliced
- - 1½ cups grated cheddar cheese
Instructions
- Preheat the oven to 400°F (200°C). Lightly butter a 9x13-inch baking dish.
- Melt the butter in a medium skillet or saucepan over medium heat.
- Add the flour and whisk continuously for about 1 minute to create a smooth roux.
- Slowly pour in the whole milk while whisking continuously. Add the vegetable broth and continue whisking until smooth.
- Stir in the grated garlic, fresh thyme, salt, and black pepper.
- Cook for 2–3 minutes, whisking frequently, until the sauce thickens slightly and lightly coats the back of a spoon. Remove from the heat.
- Arrange half of the sliced potatoes in overlapping layers across the bottom of the prepared baking dish.
- Scatter half of the sliced onion over the potatoes. Pour half of the creamy sauce evenly over the top, then sprinkle with 1 cup of grated cheddar.
- Arrange the remaining potatoes over the cheese, followed by the remaining onion and sauce.
- Finish the Scalloped Potatoes with the remaining ½ cup of cheddar cheese.
- Cover the baking dish and bake for 30 minutes.
- Carefully uncover and continue baking for another 35–40 minutes, or until the potatoes are completely tender and the cheese is bubbling and golden brown.
- Remove from the oven and allow the casserole to rest for about 20 minutes before serving. This helps the creamy sauce thicken and makes the portions easier to serve.
Notes
Yukon Gold potatoes are particularly good for homemade scalloped potatoes because their naturally creamy texture holds up well during baking.
Russet potatoes can also be used. They contain more starch and may create a softer, thicker finished casserole.
Sharp cheddar provides plenty of cheesy flavor, but you can combine it with mozzarella for additional stretch or Gruyère-style halal-suitable cheese for a different flavor profile.
For a little extra color, garnish the finished casserole with fresh thyme, parsley, or finely sliced chives.
