Cheesy Scalloped Potatoes

I still remember the first time I made cheesy scalloped potatoes for our Easter dinner and I was honestly just trying to impress my grandmother with something rich and comforting. I had no idea that one bite of those golden and creamy layers would earn me a standing ovation from the family including Grandma herself! From that day on and it’s been a beloved staple at nearly every holiday table in our home.

Since then and I’ve prepared these cheesy scalloped potatoes for Christmas and Thanksgiving and even casual winter potlucks. There’s something magical about the way the cheese melts between those thin slices of tender potato that makes this dish feel special and nostalgic all at once. Whether it’s part of a holiday feast or a comforting side for Sunday supper and it always delivers.

Ingredients

• Here’s what I use for this recipe. You can always make substitutions if you prefer!
• Russet potatoes – Sliced thin and they provide the starchy base that becomes tender and rich in the oven.
• Cheddar cheese – Sharp and melty and it adds bold flavor and gooey texture throughout.
• Heavy cream – Helps create a thick and luxurious sauce that coats every layer.
• Butter – Adds richness and helps create that golden crust on top.
• Garlic – Infuses the cream with flavor and depth.
• Onion – Brings a subtle sweetness that balances the richness.
• All-purpose flour – Helps thicken the cheesy cream sauce.
• Salt – Enhances the natural flavors of the potatoes and cheese.
• Black pepper – Adds a little warmth and contrast to the creamy layers.
• Nutmeg – Just a tiny pinch gives the dish a warm and cozy finish.

Tools You’ll Need

• Mandoline or sharp knife – To slice the potatoes thin and evenly for even cooking.
• Saucepan – Perfect for making the cream sauce before baking.
• Whisk – Helps stir the sauce until it’s smooth and creamy.
• Baking dish – The main vessel for layering the potatoes and sauce.
• Foil – Used to cover the dish while it bakes and helps keep it moist until the top is ready to brown.
• Oven – Essential for baking everything into bubbly and cheesy perfection.

Instructions

Step 1: Preheat and Prepare

I start by preheating my oven to 375°F. While that heats up and I peel and slice the potatoes very thin – I usually use a mandoline for the best results.

Step 2: Make the Sauce

In a saucepan and I melt the butter and then sauté the onion and garlic until soft. I sprinkle in the flour and whisk until a paste forms and then I slowly pour in the cream and stir until smooth. I season with salt and pepper and a tiny bit of nutmeg.

Step 3: Stir in the Cheese

Once the sauce thickens and I reduce the heat and stir in most of the shredded cheese until it’s melted and silky. I save a little cheese for topping later.

Step 4: Layer the Potatoes

I layer half the sliced potatoes into a greased baking dish and then pour half the cheese sauce over them. I repeat with the remaining potatoes and top with the rest of the sauce and that reserved cheese.

Step 5: Bake Covered

I cover the dish with foil and bake it for about 40 minutes. This lets the potatoes cook through without over-browning the top.

Step 6: Uncover and Finish

After 40 minutes and I remove the foil and bake for another 20 to 25 minutes until the top is golden and bubbling and the potatoes are fork-tender.

Step 7: Rest and Serve

I let the dish sit for about 10 minutes before serving and which helps the sauce thicken slightly and makes for perfect slices.

Tips

If you want an extra-cheesy kick and I recommend mixing in some Gruyère or Monterey Jack with the cheddar. You can also prep this dish a day in advance and just reheat it gently in the oven before serving. I’ve even added thin slices of ham or crispy bacon for a heartier version that turns it into a full meal.

Ways to Serve

I love serving cheesy scalloped potatoes as a holiday side dish next to glazed ham or roast turkey. It also pairs beautifully with a fresh green salad or some roasted vegetables for balance. And if you’re lucky enough to have leftovers and they’re incredible the next day with eggs for brunch!
