Ingredients
Scale
Vegetables
- 2 lbs Russet Potatoes (approx. 5 medium potatoes), peeled and thinly sliced
- 1 small onion, thinly sliced
Dairy & Fats
- 1/4 cup butter
- 2.5 cups milk
- 1.5 cups shredded cheddar cheese
- Parmesan cheese (optional, for serving)
Seasonings & Baking Essentials
- 3/4 teaspoon salt
- 1/4 teaspoon pepper
- 3 tablespoons all-purpose flour
- Cooking spray (to grease the baking dish)
Instructions
- Preheat and Prepare Dish: Preheat your oven to 350°F (175°C) and grease an 8×8 inch baking dish thoroughly with cooking spray to prevent sticking.
- Prepare Potatoes and Onions: Peel and thinly slice the russet potatoes and the small onion. Set them aside for layering.
- Make the Cream Sauce: In a small pot over low heat, melt the butter. Add salt, pepper, and flour, stirring constantly until the mixture is smooth and combined. Gradually increase the heat to high and add the milk in increments of 1/2 cup, stirring continuously to avoid lumps. Bring the sauce to a boil and allow it to boil for 1-2 minutes while stirring constantly. Remove from heat and stir in the sliced onions until evenly mixed.
- Assemble the Layers: In the greased baking dish, arrange a layer of potato slices, slightly overlapping each other. Pour about one-third of the cream sauce evenly over the potatoes. Repeat the layering two more times with potatoes and sauce until all are used.
- Add Cheese and Bake: Evenly sprinkle shredded cheddar cheese on top of the final layer. Cover the baking dish with foil and bake for 45 minutes. Remove the foil and bake for an additional 15 minutes uncovered, or until the cheese is golden and bubbly.
Notes
- This recipe is easy to make and yields a creamy, cheesy scalloped potato dish that feels just like a comforting homemade classic.
- For an extra cheesy finish, sprinkle some grated Parmesan cheese on top before serving.
- Use a sharp cheddar for a more intense cheese flavor.
- Be sure to slice the potatoes thinly and evenly so they cook uniformly.
- Let the dish rest for 5-10 minutes after baking to let the sauce thicken slightly and set.
