Scalloped Potatoes Recipe
Introduction
Scalloped potatoes are a comforting classic, featuring tender slices of potato baked in a creamy, savory sauce. This recipe creates a rich and flavorful side dish perfect for family dinners or holiday gatherings.

Ingredients
- 1/2 cup butter
- 1 large onion, diced
- 2 cloves garlic, minced
- 1/2 cup flour
- 2 cups milk
- 1 cup chicken broth
- 1/2 teaspoon salt
- 1/2 teaspoon pepper
- 3 pounds white potatoes, sliced about 1/4 inch thick
- Salt and pepper to taste
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish and set aside.
- Step 2: In a medium skillet, melt the butter over medium-low heat. Add the diced onion and minced garlic, cooking until the onion is softened, about 3 minutes.
- Step 3: Stir in the flour and cook for 1 to 2 minutes, stirring constantly to form a roux without browning it.
- Step 4: Gradually whisk in the milk and chicken broth, adding a little liquid at a time to prevent lumps. Continue whisking until the sauce thickens and becomes smooth.
- Step 5: Increase the heat to medium and bring the sauce to a gentle boil, stirring constantly. Add 1/2 teaspoon salt and 1/2 teaspoon pepper, then boil for 1 minute before removing from heat.
- Step 6: Arrange half of the sliced potatoes in an even layer in the prepared baking dish. Season lightly with salt and pepper.
- Step 7: Pour half of the creamy sauce evenly over the potatoes. Repeat with the remaining potatoes, seasoning again, then top with the rest of the sauce.
- Step 8: Cover the dish with foil and bake for 45 minutes.
- Step 9: Remove the foil and bake uncovered for an additional 35 to 45 minutes, or until the potatoes are tender and the top is golden brown.
- Step 10: For a crisp golden top, broil the scalloped potatoes for 3 to 4 minutes, watching carefully to prevent burning.
- Step 11: Let the potatoes rest for 15 minutes before serving to allow the sauce to set.
Tips & Variations
- Use Yukon Gold potatoes for a buttery texture and better consistency.
- Add 1 cup shredded cheddar cheese in the sauce for a cheesy variation.
- Substitute chicken broth with vegetable broth to make the dish vegetarian-friendly.
- For extra flavor, sprinkle some fresh thyme or rosemary between potato layers.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and warm in a 350°F oven until heated through, about 20 minutes. Avoid microwaving to maintain texture.

- 2 cups milk
- 1 cup chicken broth
- 1/2 teaspoon salt

Potatoes
- 3 pounds white potatoes, sliced about 1/4 inch thick
- Salt and pepper to taste
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) to get it ready for baking the scalloped potatoes.
- Make the Sauce: In a medium saucepan, melt the butter over medium-low heat, then add the diced onion and minced garlic. Cook until the onion softens, about 3 minutes. Stir in the flour and cook for 1-2 minutes to form a roux.

- Boil Sauce: Increase heat to medium and bring the sauce to a boil while whisking. Stir in salt and pepper, and let it boil for 1 minute to fully develop the flavors and thicken the sauce.
- Prepare Baking Dish and Layer Potatoes: Grease a 9×13 inch baking dish. Arrange half of the sliced potatoes in an even layer at the bottom of the dish, seasoning with salt and pepper.
- Add Sauce Layer: Pour half of the prepared cream sauce evenly over the potatoes.
- Repeat Layers: Add the remaining sliced potatoes on top of the first layer, season with salt and pepper, then pour the rest of the cream sauce over the top.
- Bake Covered: Cover the baking dish with foil and bake in the preheated oven for 45 minutes to allow the potatoes to cook through.
- Uncover and Continue Baking: Remove the foil and bake uncovered for an additional 35 to 45 minutes, or until the potatoes are tender and the top is golden brown.
- Broil for Golden Top: To achieve a beautifully golden and slightly crispy top, broil the scalloped potatoes for 3 to 4 minutes. Watch carefully to avoid burning.
- Rest Before Serving: Let the dish rest for 15 minutes after baking to allow the sauce to set and cool slightly before serving.
- Enjoy: Serve warm as a hearty, delicious side dish perfect for comforting meals.
Notes
- Use a sharp knife or a mandoline slicer to ensure uniform potato slices for even cooking.
- For a vegetarian version, substitute the chicken broth with vegetable broth.
- To make it gluten-free, use a gluten-free flour blend instead of all-purpose flour.
- Broiling time may vary depending on the oven, so watch closely to avoid burning the top.
- If you prefer a thicker sauce, use slightly less broth or cook the sauce longer before combining with potatoes.
