There are potato side dishes that are good, and then there are scalloped potatoes that are unforgettable. Easy cheesy scalloped potatoes are the latter—a creamy, cheesy, golden-baked casserole that transforms simple potatoes, milk, and cheese into pure comfort food. This version streamlines the traditional method, skipping the separate sauce-making step and letting the oven do the work. It is rich, satisfying, and surprisingly simple.
Traditional scalloped potatoes can be fussy, requiring a béchamel sauce made from scratch. This easy recipe uses a clever shortcut: layering raw potatoes and onions with shredded cheese and pouring a seasoned milk mixture over the top. As it bakes, the milk thickens into a creamy sauce, the cheese melts into a golden crust, and the potatoes become tender and buttery. The result is a dish that tastes like you spent hours in the kitchen but comes together in minutes.
These easy cheesy scalloped potatoes are perfect for holiday dinners, potlucks, Sunday suppers, or any time you need a showstopping side dish. They pair beautifully with ham, roast beef, pork chops, or roasted chicken. They are also vegetarian and endlessly customizable—add garlic, herbs, or different cheeses to make them your own.

Ingredients
Here is everything you need for easy cheesy scalloped potatoes:
For the Potatoes and Layers:
· 3 pounds Yukon Gold or russet potatoes (about 5 to 6 medium), peeled and thinly sliced (⅛ inch thick)
· 1 medium yellow onion, thinly sliced
· 3 cloves garlic, minced (optional)
· 3 tablespoons all-purpose flour
· 2 cups shredded sharp cheddar cheese (divided)
· ½ cup grated Parmesan cheese (optional)
For the Milk Mixture:
· 2 cups whole milk (or half-and-half for extra richness)
· 1 cup heavy cream (or additional milk)
· 1 teaspoon salt
· ½ teaspoon black pepper
· 1 teaspoon garlic powder
· 1 teaspoon onion powder
· ½ teaspoon paprika (optional)
· ¼ teaspoon nutmeg (optional)
For the Topping (Optional):
· ½ cup panko breadcrumbs or crushed buttery crackers
· 2 tablespoons melted butter
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Grease a 9×13-inch baking dish or a 3-quart casserole dish with butter or non-stick spray.
Step 2: Slice the Potatoes
Peel the potatoes and slice them into thin, even rounds, about ⅛ inch thick. A mandoline makes this quick and consistent, but a sharp knife works well too. Place the sliced potatoes in a large bowl of cold water to prevent browning. Drain and pat dry thoroughly before using.
Step 3: Layer the Potatoes and Onions
Arrange one-third of the potato slices in an even layer in the prepared baking dish. Sprinkle with one-third of the onion slices and one-third of the minced garlic (if using). Sprinkle with 1 tablespoon of flour and ½ cup of shredded cheddar cheese. Repeat the layers (potatoes, onion, garlic, flour, cheese) two more times, ending with cheese on top.
Step 4: Make the Milk Mixture
In a medium bowl or large measuring cup, whisk together the milk, heavy cream, salt, black pepper, garlic powder, onion powder, paprika (if using), and nutmeg (if using) until well combined.
Step 5: Pour Over Potatoes
Pour the milk mixture evenly over the layered potatoes. Gently shake the dish or tap it on the counter to help the liquid settle between the layers. Sprinkle the remaining cheese and Parmesan (if using) over the top.
Step 6: Add the Topping (Optional)
If using a crunchy topping, combine the panko breadcrumbs or crushed crackers with the melted butter and sprinkle over the cheese.
Step 7: Bake
Cover the baking dish with aluminum foil. Bake for 45 minutes. Remove the foil and bake uncovered for another 20 to 30 minutes, until the potatoes are fork-tender, the sauce is bubbly, and the top is golden brown and crispy.
Step 8: Rest and Serve
Let the scalloped potatoes rest for 10 to 15 minutes before serving. This allows the sauce to thicken and the layers to set for cleaner slices. Garnish with fresh parsley if desired.
Cooking Tips and Pro Tips for Best Results
· Slice potatoes thinly and evenly: Uniform ⅛-inch slices ensure even cooking. A mandoline is the best tool for this job.
· Do not skip soaking the potatoes: Soaking removes excess starch and prevents the potatoes from turning brown. Pat them completely dry before layering.
· Use Yukon Gold potatoes for creaminess: Yukon Golds are naturally buttery and hold their shape well. Russets are starchier and will break down more, creating a thicker, more casserole-like texture.
· Shred your own cheese: Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Grate cheese from a block for the best, creamiest results.
· Let the casserole rest: Resting allows the sauce to thicken, making it easier to slice and serve.
· Make it ahead: Assemble the casserole (without the crunchy topping) up to 24 hours in advance. Cover and refrigerate. Add 10 to 15 minutes to the covered baking time.
Variations and Substitutions
· Garlic scalloped potatoes: Add 6 cloves of thinly sliced garlic between the layers.
· Herbed scalloped potatoes: Add 1 teaspoon of dried thyme or rosemary to the milk mixture.
· Bacon scalloped potatoes: Sprinkle ½ cup of crumbled cooked bacon between the layers.
· Ham and scalloped potatoes: Add 1 cup of diced cooked ham between the layers.
· Three-cheese scalloped potatoes: Use a blend of cheddar, Gruyère, and Parmesan.
· Gluten-free: Use a gluten-free flour blend or omit the flour. The sauce will be thinner but still delicious. Use gluten-free breadcrumbs for the topping.
· Dairy-free: Use unsweetened almond or oat milk, dairy-free cream, and dairy-free cheese. The sauce will be thinner.
· Add vegetables: Layer in thinly sliced mushrooms or leeks.
Serving Suggestions
These easy cheesy scalloped potatoes are a versatile side dish that pairs beautifully with:
· Ham or pork roast: A classic pairing.
· Roast beef or prime rib: The creamy potatoes complement hearty meats.
· Roasted chicken or turkey: Perfect for Thanksgiving or Sunday dinner.
· Grilled sausages or meatloaf: A great potluck combination.
· Simple green salad: Adds freshness and crunch.
· Steamed green beans or asparagus: Extra vegetables on the side.

Frequently Asked Questions
What is the difference between scalloped potatoes and au gratin potatoes?
Scalloped potatoes are typically layered with a cream or milk sauce and sometimes cheese. Au gratin potatoes always include cheese and often a breadcrumb topping. This recipe is a hybrid—creamy and cheesy with an optional crunchy topping.
Do I need to peel the potatoes?
Peeling is recommended for a smooth, creamy texture, especially with russet potatoes. Yukon Gold skins are thin and can be left on if you prefer a more rustic dish.
Why are my scalloped potatoes runny?
Runny potatoes usually mean the dish did not rest long enough, or there was too much liquid. Let the casserole rest for 10 to 15 minutes after baking. Next time, use slightly less milk or add an extra tablespoon of flour.
Can I use pre-shredded cheese?
You can, but freshly shredded cheese melts more smoothly. Pre-shredded cheese contains anti-caking agents that can make the sauce grainy.
Can I make these in a slow cooker?
Yes. Layer the potatoes, onions, flour, and cheese in a greased slow cooker. Pour the milk mixture over the top. Cook on LOW for 4 to 5 hours or on HIGH for 2 to 3 hours. Sprinkle with cheese and breadcrumbs during the last 30 minutes.
Can I add ham or bacon?
Absolutely. Layer diced cooked ham or crumbled cooked bacon between the potato layers.
Is this recipe gluten-free?
Not as written. Omit the flour (the sauce will be thinner) or use a gluten-free flour blend. Use gluten-free breadcrumbs for the topping.
How do I get a crispy topping?
Use panko breadcrumbs or crushed buttery crackers mixed with melted butter. Sprinkle over the cheese during the last 15 to 20 minutes of baking, uncovered.
