Equipment You’ll Need

You don’t need any fancy gadgets to make these cheesy scalloped potatoes — just a few reliable kitchen basics that will help you get the job done easily. These are tools I personally use and recommend in my own kitchen.

• 9×13-inch baking dish
  A classic size for this dish, ensuring the potatoes bake evenly and the sauce spreads beautifully.
• Medium saucepan
  Perfect for making the creamy cheese sauce, so you can melt and mix everything together smoothly.
• Mandolin slicer or sharp chef’s knife
  A mandolin makes it quick and easy to get those perfectly even potato slices. If you don’t have one, a sharp knife works just fine.
• Whisk
  For stirring the milk and cream into the flour and ensuring your sauce is nice and smooth.
• Measuring cups and spoons
  For getting your ingredients just right — especially for the flour, milk, and seasonings.
• Aluminum foil
  You’ll cover the dish while baking for the first 30 minutes, ensuring everything cooks evenly and stays tender.
• Oven mitts
  For safe handling when taking the hot baking dish in and out of the oven.
• Grater
  To shred the sharp cheddar and Parmesan cheese to get the best melt and flavor.

Optional but very useful:

• Large spoon or ladle
  To evenly distribute the cheese sauce between the potato layers for a smooth finish.

Tip: If you don’t already have some of these tools, they’re easy to find at your local kitchen store or online. They’re basic kitchen essentials you’ll use again and again.

Ingredients You’ll Need

For the Cheese Sauce

• 2 tablespoons unsalted butter
• 1 small yellow onion, finely chopped
• 2 cloves garlic, minced
• 2 tablespoons all-purpose flour
• 1 1/2 cups whole milk
• 1 cup heavy cream
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon dried thyme
• 1 1/2 cups shredded sharp cheddar cheese
• 1/2 cup grated Parmesan cheese

For the Potatoes

• 2 pounds Yukon Gold potatoes, thinly sliced (about 1/8 inch)

Optional Garnish

• Chopped fresh parsley for a pop of color

Prepping the Perfect Cheesy Scalloped Potatoes

This is one of those recipes where a few small steps really make the biggest difference. From slicing the potatoes to layering the cheese sauce just right—I’ll walk you through it like we’re cooking together.

Step 1: Preheat and Prep

Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish. I like to use a bit of butter or nonstick spray for easy cleanup.

Step 2: Sauté the Aromatics

In a medium saucepan, melt the butter over medium heat. Add your chopped onion and cook until soft, about 3-4 minutes. Then toss in the garlic and stir for 30 seconds.

Step 3: Make the Creamy Cheese Sauce

Whisk in the flour and cook it for a minute or two to get rid of that raw taste. Then gradually pour in the milk and cream, whisking constantly.

Add your seasonings: salt, pepper, and thyme. Let it bubble gently until it thickens—about 3-5 minutes.

Remove from heat and stir in 1 1/2 cups of the cheddar cheese until it’s totally melted and smooth.

Step 4: Slice and Layer

Peel and slice the Yukon Gold potatoes to about 1/8-inch thick. I use a mandolin for even slices, but a sharp knife works just fine.

Layer half the potatoes in your prepared dish. Pour on half of the cheese sauce. Spread it out evenly. Repeat with the remaining potatoes and sauce.

Step 5: Add More Cheese on Top

Sprinkle the remaining 1/2 cup cheddar cheese and all of the Parmesan evenly across the top. This creates that beautiful golden, bubbly finish.

Step 6: Bake Until Golden

Cover your dish with foil and bake for 30 minutes. Then remove the foil and bake for another 25-30 minutes until the top is golden and the potatoes are tender when pierced.

Step 7: Let It Rest

Don’t skip this step! Let the scalloped potatoes sit for 10 minutes before serving. It helps everything set and makes serving cleaner.

My Personal Tips for Cheesy Scalloped Potato Success

• Shred your own cheese for the best melt. Pre-shredded often contains anti-caking agents that mess with texture.
• Slice the potatoes evenly so they cook at the same rate.
• No need to boil the potatoes first! This saves time and keeps them from getting mushy.

Variations and Add-Ins

This recipe is a fantastic base. Here are a few delicious twists:

• Add ham for a hearty main dish
• Mix in some Gruyère or Fontina for gourmet flavor
• Sprinkle breadcrumbs on top for a crunchy finish
• Stir in chopped green onions or bacon bits for extra flavor

What to Serve With Cheesy Scalloped Potatoes

These potatoes are rich, so they pair beautifully with:

• Roasted or grilled meats (chicken, beef, pork)
• A crisp green salad
• Steamed green beans or asparagus

Or honestly, just eat them on their own with a fork. No judgment.

Storing and Reheating Leftovers

Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the oven at 350°F covered with foil, or pop them in the microwave for a quick warm-up.

They’re just as delicious (maybe even more so) the next day.

FAQs About Cheesy Scalloped Potatoes Recipe

Can I make this ahead of time?
Absolutely! Assemble it fully, cover with foil, and refrigerate for up to 24 hours. Bake when you’re ready.

Why are my scalloped potatoes watery?
They may not have baked long enough. Be sure to remove the foil so the top can reduce and thicken.

Can I freeze leftovers?
You can, but the texture may change slightly. For best results, reheat from thawed in the oven.

Can I use other types of potatoes?
Yes! Russets work well too, but I prefer Yukon Gold for their buttery texture.
