Description
A creamy and cheesy potato dish that’s perfect as a side for any meal.
Ingredients
Scale
- 2 pounds gold potatoes, peeled and sliced 1/8-inch thick
- 4 tablespoons unsalted butter
- 4 tablespoons all-purpose flour
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1 teaspoon salt
- 1 teaspoon pepper
- 2 cups whole milk (or half-and-half for extra creaminess)
- 2 cups freshly shredded sharp Cheddar cheese, divided
- 1/2 cup freshly grated Parmesan cheese, divided
Instructions
- Preheat oven to 350°F. Grease a 9×9-inch (or 2-quart) baking dish with cooking spray and set aside.
- Peel, wash, and slice the potatoes into thin 1/8-inch rounds using a mandoline or sharp knife.
- Melt butter in a large pot over medium heat. Whisk in flour, garlic powder, onion powder, salt, and pepper. Cook, whisking constantly, for 1 minute.
- Gradually whisk in milk, a little at a time, until smooth with no lumps. Increase heat to medium-high and cook until the sauce thickens enough to coat the back of a spoon, about 4–6 minutes.
- Remove from heat. Gradually stir in 1-1/2 cups Cheddar and 1/4 cup Parmesan, adding a small handful at a time. Stir gently after each addition until the cheese is melted and the sauce is smooth before adding more.
- Add sliced potatoes and gently toss with a rubber spatula to coat evenly without breaking the slices.
- Pour the mixture into the prepared baking dish and smooth into an even layer.
- Cover tightly with foil and bake for 1 hour and 15 minutes, or until the potatoes are fork-tender.
- Remove foil and sprinkle the remaining 1/2 cup Cheddar and 1/4 cup Parmesan evenly over the top.
- Return to the oven, uncovered, for 15–20 minutes, until the top is golden and bubbling.
- Optional: Move the oven rack to the upper-middle position and broil for 1 minute, watching very closely to prevent burning.
Notes
- To ensure even cooking, slice the potatoes as uniformly as possible.
- Half-and-half can be used for a richer sauce.
