Ingredients for Classic Scalloped Potatoes
Crafting delicious scalloped potatoes starts with high-quality, straightforward ingredients. These pantry staples combine to create an unforgettable dish.
- ¼ cup salted butter: Provides a rich base for your creamy sauce.
- 1 large yellow onion: Diced for subtle sweetness and aromatic depth.
- 2 cloves garlic: Minced, adding a fragrant, savory kick.
- ¼ cup all-purpose flour: Essential for creating a smooth, thick roux. Understanding the technique of the culinary technique of a roux is fundamental in many creamy sauces.
- 2 cups milk: Whole milk is recommended for the creamiest texture.
- 1 cup chicken broth: Adds a savory dimension to the sauce; vegetable broth works too.
- 1 ¼ teaspoon salt (divided): Crucial for seasoning both the sauce and potato layers.
- ½ teaspoon black pepper (divided): Freshly ground pepper enhances the flavor.
- 3 pounds Yukon gold potatoes (or red potatoes, see notes, sliced about ⅛-inch thick): The star of the dish, providing a tender, hearty texture.
Notes & Substitutions
Selecting the right ingredients truly elevates your scalloped potatoes.
- Potatoes: Use waxy varieties like Yukon gold potatoes or red potatoes. They hold their shape well during baking and offer a creamy texture. If you opt for starchy russets, make sure to peel them thoroughly, as their skins are thicker.
- Aromatics: Take your time to soften the diced onion and minced garlic properly. This step is key to building a deep, flavorful base for your sauce. Do not rush this process.
- Sauce liquid: Whole milk creates the most luxurious and creamy sauce. Combine it with chicken broth for a rich, savory depth that perfectly complements the potatoes. For a vegetarian version, simply swap chicken broth for vegetable broth.
- Seasonings: Remember to salt and pepper each individual potato layer, not just the sauce. Layered seasoning ensures every bite of your scalloped potatoes is perfectly flavored from edge to center.
- Optional additions: Feel free to incorporate other herbs. A pinch of dried thyme or some fresh parsley, stirred into the sauce, can add another layer of aromatic complexity.
- Cheese option: If you prefer a cheesy version (often called au gratin), stir in about 1-1.5 cups of shredded sharp cheddar or Gruyère cheese into the warm sauce, or layer it between potato slices. See our Pro Tips for the best way to add cheese.
Equipment Needed
Having the right tools simplifies making these delicious scalloped potatoes.
- Mandoline slicer: Highly recommended for achieving perfectly thin and uniform potato slices, which ensures even cooking.
- Large saucepan: Essential for preparing the creamy, flavorful sauce.
- 9×13 inch casserole dish: The ideal size for baking a generous portion of this classic side dish.
- Whisk: Ensures a smooth, lump-free sauce every time.
How to Make Scalloped Potatoes
Crafting perfect scalloped potatoes is straightforward with these step-by-step instructions. This recipe guides you through creating a rich, creamy sauce and baking tender, flavorful layers.
Preheat the oven to 350°F (175°C). Lightly grease a 9×13 inch casserole dish with butter or cooking spray and set it aside. This prevents sticking and makes cleanup easier.
Prepare the Creamy Sauce
- Melt ¼ cup of salted butter in your large saucepan over medium heat. Allow it to melt completely until it just begins to shimmer.
- Add the diced yellow onion to the melted butter. Cook, stirring occasionally, for 5-7 minutes, until the onion softens and becomes translucent. Do not brown it.
- Stir in the 2 minced garlic cloves. Cook for just 1 minute more, until fragrant. Be careful not to burn the garlic, as it can turn bitter.
- Sprinkle ¼ cup of all-purpose flour over the softened onions and garlic. Stir continuously for 2 minutes to create a roux. This step cooks out the raw flour taste and helps thicken the sauce later.
- Gradually whisk in 2 cups of milk, a little at a time, ensuring each addition is fully incorporated before adding more. This prevents lumps. Continue whisking until the mixture is smooth.
- Pour in 1 cup of chicken broth, continuing to whisk until fully combined.
- Bring the sauce to a gentle boil, whisking constantly. Once boiling, reduce the heat to low and simmer for 1 minute, until the sauce visibly thickens. It should coat the back of a spoon.
- Remove the saucepan from the heat. Season the sauce with ½ teaspoon of the divided salt and ¼ teaspoon of the divided black pepper. Stir well to combine the seasonings.
Layer and Bake
- While the sauce is cooling slightly, thinly slice the 3 pounds of Yukon gold potatoes about ⅛-inch thick. A mandoline slicer is ideal for achieving consistent, even slices, which are crucial for uniform cooking of the scalloped potatoes.
- Arrange one-third of the thinly sliced potatoes in a single, slightly overlapping layer across the bottom of your greased casserole dish.
- Lightly season this potato layer with ¼ teaspoon of the remaining salt and ⅛ teaspoon of the remaining black pepper. Distribute the seasonings evenly.
- Pour one-third of the creamy sauce evenly over the first layer of seasoned potatoes, ensuring they are well-covered.
- Repeat this layering process twice more: add another layer of potatoes, season it with salt and pepper, then cover with another third of the sauce.
- Finally, add the last layer of potatoes, season with the remaining salt and pepper, and pour the last third of the sauce evenly over the top, making sure all potatoes are moistened.
- Cover the casserole dish tightly with aluminum foil. This helps the potatoes steam and become tender during the initial baking phase.
- Bake covered in the preheated oven for 45 minutes.
- After 45 minutes, carefully remove the aluminum foil. Return the uncovered dish to the oven and continue baking for an additional 35-45 minutes. Bake until the top is golden brown, bubbly, and the potatoes are fork-tender. You can test tenderness by gently piercing a potato slice with a fork.
- If you desire an extra crispier, golden topping for your scalloped potatoes, you can briefly broil the dish for 2-3 minutes at the very end. Watch it carefully to prevent burning.
- Remove the dish from the oven. Allow the scalloped potatoes to rest for at least 20 minutes before serving. This crucial resting period allows the sauce to set and thicken beautifully, preventing a watery dish.
Pro Tips for Perfect Scalloped Potatoes
Achieving perfectly tender and flavorful scalloped potatoes is simple with these expert tips.
- Slice potatoes uniformly: Use a mandoline or a very sharp knife to cut potatoes into consistent ⅛-inch thick slices. Uniformity ensures every potato cooks evenly and avoids crunchy or undercooked pieces.
- Season every layer: Do not skip seasoning each layer of potatoes with salt and pepper. This builds flavor throughout the dish, ensuring rich taste in every bite, rather than just the top or bottom.
- Avoid curdling cheese: If you’re adding cheese for a cheesy variation, stir it into the warm sauce off the heat. This prevents the cheese from separating or becoming grainy, keeping your sauce smooth.
- Prevent dry potatoes: Make sure the creamy sauce fully covers the top layer of potatoes before baking. This helps keep the potatoes moist and prevents them from drying out or browning too quickly.
- Resting is crucial: Allow your scalloped potatoes to rest for at least 20 minutes after baking. This time lets the sauce properly set and thicken, resulting in a cohesive, perfectly structured dish that holds together when served.
Serving Suggestions, Storage, and Variations
These classic scalloped potatoes are incredibly versatile.
Serving Suggestions
- Perfect alongside roasted chicken, a holiday ham, or a juicy turkey dinner.
- Great with steak or pan-seared pork tenderloin for an elevated weeknight meal.

Make Ahead & Freezing
- Make Ahead (up to 2 days): Prepare the dish completely and par-bake it covered for about 30 minutes. Let it cool completely, then refrigerate. When ready to serve, reheat uncovered at 350°F (175°C) until bubbly and golden, about 45-60 minutes.
- Freezing: Bake the scalloped potatoes partially (covered for 45 minutes, uncovered for 20 minutes). Cool completely, then cover tightly with plastic wrap and foil. Freeze for up to 3 months. Thaw overnight in the refrigerator, then bake from chilled, adding extra covered time if needed.
Recipe Variations
- Cheesy Scalloped Potatoes (Au Gratin style): Stir 1 to 1.5 cups of shredded sharp cheddar, Gruyère, or Parmesan cheese into the warm sauce before layering, or sprinkle cheese between potato layers for extra indulgence.
- Herbaceous: Enhance the flavor by adding fresh rosemary, thyme, or chives directly into the sauce or sprinkled over the layers.
- Hearty addition: For a more substantial meal, layer cooked, crumbled bacon pieces or diced ham between the potato and sauce layers.
