Ingredients

Scale

Potatoes & Vegetables

  • 4 russet potatoes, peeled and sliced into ¼-inch slices (about 2 pounds)
  • 1 yellow onion, sliced into rings

Cheese Sauce

  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • ½ teaspoon kosher salt
  • 2 cups whole milk, room temperature
  • 1 ½ cups mild cheddar cheese, shredded

Seasoning

  • Salt and pepper to taste

Instructions

  1. Preheat Oven and Prepare Dish: Preheat the oven to 400°F (200°C). Lightly spray an 8×8-inch casserole dish with nonstick cooking spray to prevent sticking.
  2. Arrange Potatoes and Onions: Layer the potato slices and onion rings alternately in the prepared baking dish, staggering them evenly for balanced cooking and flavor distribution.
  3. Make the Cheese Sauce: In a medium saucepan, melt the unsalted butter over medium heat. Whisk in the all-purpose flour and kosher salt, stirring constantly for about one minute to create a roux. Gradually add the room temperature whole milk, whisking continuously until the mixture thickens to a creamy consistency.
  4. Add the Cheese: Remove the saucepan from heat, then stir in the shredded mild cheddar cheese all at once. Continue stirring until the cheese is fully melted and the sauce is smooth, which should take about 30 to 60 seconds.
  5. Combine and Cover: Pour the prepared cheese sauce evenly over the arranged potatoes and onions in the casserole dish. Cover the dish tightly with aluminum foil to retain moisture during baking.
  6. Bake the Potatoes: Place the covered dish in the preheated oven and bake for 85 to 90 minutes, or until the potatoes are tender when pierced with a fork.
  7. Broil for a Crisp Topping: After baking, remove the foil and switch your oven setting to broil. Broil the casserole until the top is golden brown and slightly crisp, watching carefully to prevent burning.
  8. Season and Serve: Remove the dish from the oven, season with salt and pepper to taste, and serve warm as a delicious side dish.

Notes

  • Use room temperature milk to prevent lumps in the cheese sauce.
  • Thin slices of potatoes ensure even cooking and a tender texture.
  • Broiling at the end adds a lovely golden crust to the dish.
  • Covering with foil during baking helps retain moisture and prevents the potatoes from drying out.
  • This dish can be prepared ahead and baked just before serving.
