Let's Make Cheesy Scalloped Potatoes (Step-by-Step)
Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter.
Step 2: Make the Sauce
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes. Gradually whisk in the milk. Cook, stirring constantly, until the sauce thickens. Season with salt, pepper, garlic powder, and paprika.
Step 3: Layer the Potatoes
Arrange a layer of sliced potatoes in the prepared dish. Top with a layer of sliced onions (if using). Sprinkle with cheese. Repeat the layers.
Step 4: Pour the Sauce
Pour the sauce over the potatoes.
Step 5: Dot with Butter
Dot the top with butter.
Step 6: Cover and Bake
Cover the dish with foil and bake for 45 minutes.
Step 7: Uncover and Bake
Remove the foil and bake for an additional 15-20 minutes, until the potatoes are tender and the top is golden and bubbly.
Step 8: Rest and Serve
Let the dish rest for 5-10 minutes before serving.
Tips for the Best Cheesy Scalloped Potatoes
Slice the potatoes thinly. Thin slices cook more evenly.
Use a good quality cheese. It makes a difference.
Don't overcook the sauce. The sauce should be thick but not lumpy.
Layer evenly. Even layers ensure even cooking.
Cover with foil. Covering prevents the top from burning.
Let it rest. Resting allows the dish to set.
