Ingredients
Scale
Main Ingredients
- 2 lbs Russet Potatoes (approx. 5 medium potatoes)
- 1 small Onion
- 1/4 cup Butter
- 3/4 teaspoon Salt
- 1/4 teaspoon Pepper
- 3 tablespoons Flour
- 2.5 cups Milk
- 1.5 cups Cheddar Cheese, shredded
- Parmesan Cheese (optional, for serving)
Instructions
- Preheat and Prepare Dish: Preheat your oven to 350°F (175°C) and grease an 8×8-inch baking dish well with cooking spray to prevent sticking.
- Slice Potatoes and Onion: Peel the russet potatoes and thinly slice them. Thinly slice the onion as well. Set these aside for layering.
- Make the Cream Sauce: In a small pot over low heat, melt the butter. Stir in salt, pepper, and flour until smooth. Gradually increase heat to high, adding milk in 1/2 cup increments while stirring constantly. Bring the mixture to a boil and continue boiling for 1-2 minutes until thickened. Remove from heat and stir in the sliced onions.
- Layer Potatoes and Sauce: Arrange a layer of sliced potatoes in the baking dish with slight overlap. Pour one-third of the cream sauce over the potatoes. Repeat this layering two more times, ending with the sauce.
- Add Cheese and Bake: Sprinkle shredded cheddar cheese evenly over the top of the assembled casserole. Cover with foil and bake for 45 minutes. Then, remove the foil and bake uncovered for an additional 15 minutes or until the cheese is golden and bubbly.
Notes
- This recipe is simple to make and delivers a super creamy, cheesy texture.
- Using russet potatoes ensures the best texture for the scalloped potatoes.
- Optional: Sprinkle Parmesan cheese on top before baking for extra flavor.
- Let the dish rest for a few minutes after baking to set before serving.
