Step‑by‑Step Instructions for Cheesy Scalloped Potatoes
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While the oven heats, take an 8-inch square baking dish and generously grease it with butter to ensure your delicious cheesy scalloped potatoes don’t stick. This step sets the foundation for a glorious, bubbly dish that will soon fill your home with comforting aromas.
Step 2: Slice the Potatoes
Next, peel and slice your russet potatoes into even ¼-inch thick rounds. This thickness ensures that they cook evenly, becoming tender and flavorful. As you slice, place the potatoes in a bowl of cold water to prevent browning. A good visual cue is their creamy texture and pale hue, which will transform beautifully in the oven.
Step 3: Prepare the Onion
Peel the yellow onion and slice it thinly. The sweet aroma of the onion will mingle beautifully with the creamy sauce, enhancing the overall flavor of your cheesy scalloped potatoes. Keep the slices uniform to ensure they cook evenly, creating a delightful softness that contrasts perfectly with the tender potatoes.
Step 4: Layer the Ingredients
Now it’s time to layer your ingredients. Place half of the potato slices neatly in the prepared dish, followed by half of the onion slices. Repeat this layering process, ensuring to artfully arrange the ingredients to create a visual feast. The layers should be slightly overlapping, creating a gorgeous tapestry of color and texture.
Step 5: Make the Cheese Sauce
In a medium saucepan over medium-low heat, melt 4 tablespoons of butter until bubbling gently. Whisk in ¼ cup of all-purpose flour along with a pinch of salt for about one minute until it turns a light golden color. This process will form the roux, which will give your cheese sauce that dense, luscious consistency.
Step 6: Add Milk and Cheese
Slowly pour in 2 cups of warmed whole milk while continuously stirring the mixture. Cook for 4-5 minutes, until the sauce thickens and coats the back of a spatula. Once thick, remove it from heat and add in 2 cups of grated cheddar cheese. Stir until fully melted and creamy, creating the rich sauce that will envelop your potatoes.
Step 7: Pour the Sauce
Carefully pour the cheesy sauce over the layered potatoes and onions, ensuring an even distribution. Use a spatula to gently press down so the sauce seeps into every crevice. The tantalizing aroma of the cheese will immediately start to lift as you prepare your cheesy scalloped potatoes for baking.
Step 8: Bake the Dish
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 90 minutes, until the potatoes are tender and the top is golden brown. You can test doneness by inserting a knife through the layers; it should slide in easily. This slow cooking allows all the flavors to meld beautifully.
Step 9: Broil for Crispiness
For that irresistible golden-brown topping, switch the oven to broil for an additional 5-10 minutes after the baking time. Watch closely to prevent burning as the top becomes deliciously crispy. This final touch will elevate your cheesy scalloped potatoes to pure comfort food perfection, inviting everyone to the dinner table.

- Potato Prep: Keep sliced potatoes in cold water until ready to use; this prevents browning and guarantees they remain fresh.

Cheesy Scalloped Potatoes Recipe FAQs
What type of potatoes should I use for Cheesy Scalloped Potatoes?

Very! If your cheese sauce is too thin, you can try simmering it a little longer to evaporate excess liquid, or creating a quick roux by melting a tablespoon of butter and whisking in a tablespoon of flour until golden, then gradually adding to the original sauce while stirring.
