How to Make Cheesy Garlic Scalloped Potatoes
Step 1: Prep the Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). A hot oven is essential for perfectly cooked potatoes and an irresistibly golden top. Lightly grease a 9×13-inch baking dish—this not only prevents sticking, but also makes cleanup a breeze.
Step 2: Sauté the Garlic
Grab a medium saucepan and melt your butter over medium heat. As soon as it’s melted, toss in the minced garlic. Let it sizzle for about a minute until it’s wonderfully fragrant, being careful not to let it brown. This is the foundation of all that garlicky goodness in your Cheesy Garlic Scalloped Potatoes.
Step 3: Make the Cheese Sauce
Whisk in the flour until it absorbs the butter, forming a smooth paste (this is your roux). Let it cook for a minute to lose any raw flour taste. Then, slowly whisk in your whole milk and heavy cream, stirring constantly to avoid lumps. Keep at it for 3–4 minutes, until the mixture starts to thicken. Take the pan off the heat and stir in the salt, pepper, and thyme if you’re using it. Next, fold in the cheddar and Parmesan cheeses, whisking until silky and smooth.
Step 4: Layer the Potatoes and Sauce
This is where the magic builds! Arrange half of your potato slices evenly in the prepared baking dish. Pour half the cheese sauce over the top, making sure each slice is coated. Repeat this process with the rest of the potatoes and the remaining sauce, finishing with a sprinkle of cheddar cheese over everything.
Step 5: Bake
Cover your casserole tightly with foil and bake for 30 minutes—this helps everything steam and cook through. Then, remove the foil and bake another 25–30 minutes. You’re looking for potatoes that are fork-tender and a top that’s bubbling, golden, and utterly inviting.
Step 6: Rest and Garnish
Let your Cheesy Garlic Scalloped Potatoes rest for about 10 minutes out of the oven. This helps the sauce set up and makes for easier serving. Finish with a generous shower of fresh chopped parsley before digging in.

Make Ahead and Storage
Storing Leftovers
Simply transfer any leftovers to an airtight container, or cover your baking dish tightly with foil. Kept in the fridge, Cheesy Garlic Scalloped Potatoes will stay fresh and delicious for up to 4 days—if they last that long!
Freezing
Yes, you can freeze this dish! Let the potatoes cool completely, wrap tightly with plastic wrap and foil, and freeze for up to two months. Just know that the sauce may separate ever-so-slightly upon thawing—but a gentle reheat sorts everything out.
Reheating
For best results, reheat leftovers in the oven. Place the potatoes in a covered baking dish and warm at 300°F until bubbling and hot throughout. You can use the microwave for smaller portions—just go slow and stir between bursts.
FAQs
Can I use a different kind of cheese for Cheesy Garlic Scalloped Potatoes?
Definitely! While sharp cheddar is classic for that bold, melty flavor, you can try Gruyère, Fontina, or Monterey Jack for delicious results. Just be sure to use a cheese that melts well for the creamiest finish.
What’s the best way to slice potatoes for this dish?
Thin, even slices are key for perfectly tender Cheesy Garlic Scalloped Potatoes. Using a sharp knife works, but a mandoline makes the job faster and gives you uniform pieces for the prettiest layers.
Can I make this recipe ahead of time?
Absolutely! Assemble the casserole up to a day ahead, cover, and refrigerate until you’re ready to bake. Add a few extra minutes to the baking time if starting from cold.
How do I keep the sauce from curdling?

Is there a way to make this gluten-free?
Yes! Simply swap the all-purpose flour for a gluten-free blend or use cornstarch. The rest of the ingredients are naturally gluten-free, so everyone can enjoy.
