Story

Scalloped Potatoes have always played a special role at family tables, especially during holidays and Sunday dinners. I first learned to make them while helping prepare large meals where the side dishes mattered just as much as the main course. This recipe keeps the heart of classic scalloped potatoes intact while offering consistency that home cooks appreciate. The thin slices cook evenly, the sauce stays smooth, and the final bake delivers that familiar comfort. Over time, this version became my go-to golden potato side because it pairs easily with roasted meats, baked chicken, or even a simple salad.

Ingredients

4 large russet potatoes, peeled and thinly sliced
1 medium onion, thinly sliced
3 tablespoons unsalted butter
3 tablespoons all-purpose flour
2 cups whole milk
1½ cups shredded cheddar cheese (optional)
1 teaspoon salt
½ teaspoon black pepper
Fresh thyme or parsley for garnish (optional)

Step-by-Step Instructions

Preparing the Ingredients

Wash and peel the potatoes, then slice them into evenly thin rounds to help them cook at the same rate. Slice the onion into thin strips so it softens fully during baking. Measure all ingredients before starting, which keeps the process smooth and prevents mistakes while cooking.

Cooking Instructions

Preheat the oven to 350°F and grease a baking dish generously. Melt the butter in a saucepan over medium heat, then whisk in the flour until smooth. Slowly add the milk while whisking constantly, allowing the sauce to thicken gently. Season with salt and pepper, then remove from heat. Arrange a layer of potatoes and onions in the dish, spoon sauce over the top, and add cheese if using. Repeat the layers until everything is used, finishing with sauce and cheese. Cover with foil and bake for 45 minutes, then uncover and bake for another 15 minutes until bubbly and lightly browned.

Tips for Perfect Results

Common Mistakes to Avoid

Avoid slicing potatoes too thick, as uneven slices cause undercooked centers. Do not rush the sauce thickening step, since a thin sauce leads to watery results. Always cover the dish for the first bake so the potatoes soften properly before browning.

Pro Tips for Better Flavor

Use whole milk for a richer sauce and season each layer lightly to build flavor throughout. Let the dish rest after baking so the sauce settles and thickens naturally. For deeper flavor, try mixing sharp cheddar with mild cheese for balance in this layered potato casserole.

Serving and Storage

How to Serve

Serve Scalloped Potatoes hot as a side with roasted chicken, beef, or ham. They also work beautifully alongside vegetables for a balanced plate. A sprinkle of fresh herbs adds color and brightness right before serving.

How to Store Leftovers

Store leftovers in an airtight container in the refrigerator for up to three days. Reheat gently in the oven or microwave until warmed through. Add a splash of milk before reheating to keep the sauce creamy.

Conclusion

Frequently Asked Questions

Can I make scalloped potatoes ahead of time?

Yes, you can assemble the dish a day in advance, cover it tightly, and refrigerate. Bake it fresh when needed, adding a few extra minutes to account for the chilled temperature.

Do scalloped potatoes need cheese?

Traditional versions rely on a creamy sauce without cheese, but adding it creates a richer flavor. This recipe allows both options so you can adjust based on preference.

What potatoes work best for scalloped potatoes?

Russet potatoes work best because they soften evenly and absorb the sauce well. Yukon Gold potatoes also work if you prefer a slightly firmer texture.
