Cheesy Garlic Scalloped Potatoes Recipe 

So you want something that screams comfort food but also makes you look like you actually know what you’re doing in the kitchen? Enter cheesy garlic scalloped potatoes—the dish that’s basically a warm hug in casserole form. Layers of tender potatoes swimming in garlicky cream sauce, topped with a blanket of melted cheese that gets all golden and bubbly. Yeah, we’re going there. And the best part? It’s way easier than it looks. No fancy chef skills required, just a little patience and a lot of cheese. Let’s do this.

Why This Recipe is Awesome

Look, I’m gonna be straight with you. This recipe is basically foolproof. If I can make it without setting off the smoke alarm or creating a kitchen disaster, so can you. The potatoes get ridiculously creamy, the garlic adds that perfect savory punch, and the cheese? Well, the cheese does what cheese does best—makes everything better.

This dish is also insanely versatile. Thanksgiving dinner? Check. Tuesday night because you deserve something fancy? Also check. Trying to impress your in-laws or that person you’re definitely not trying too hard for? Triple check. It looks impressive, tastes like you slaved away for hours, but honestly takes maybe 20 minutes of actual work. The oven does the rest while you Netflix and chill (or whatever kids call it these days).

Plus, it’s one of those recipes where people will ask you for the recipe, and you get to feel all smug about how “oh, it’s nothing really” when secretly you’re like “yeah, I’m amazing.” We all need that confidence boost sometimes.

Ingredients You’ll Need

Here’s what you’re gonna grab from your kitchen (or the store if you’re running on empty):

• 4 pounds of russet potatoes – The MVPs of this dish. Don’t skimp here.
• 3 cups heavy cream – Because we’re not here to count calories, we’re here for happiness.
• 1 cup whole milk – Thins out the cream just enough. You could use all cream, but let’s not go completely wild.
• 4 cloves of garlic, minced – Fresh is best. That jarred stuff? Meh, if that’s all you got, I won’t judge… much.
• 3 cups shredded cheese – I recommend a mix of sharp cheddar and Gruyere, but honestly, use what makes your heart sing.
• 4 tablespoons butter – Real butter, people. Not that weird spreadable stuff.
• 3 tablespoons all-purpose flour – For thickening. Science!
• 1 teaspoon salt – Adjust to taste, obviously.
• ½ teaspoon black pepper – Freshly ground if you’re feeling fancy.
• ½ teaspoon dried thyme – Optional, but it adds a nice touch.
• Fresh parsley for garnish – Also optional. Mostly for making it pretty for the ‘gram.

Step-by-Step Instructions

1. Preheat your oven to 375°F (190°C). I know, I know, preheating feels like a waste of time. But trust me on this one. Grease a 9×13 inch baking dish with butter or cooking spray. Set it aside and feel accomplished already.
2. Slice those potatoes. Peel them if you want (I usually do for this recipe), then slice them about ⅛ inch thick. A mandoline slicer is your best friend here, but a sharp knife works too. Just try to keep them uniform so they cook evenly. Nobody wants some slices turning to mush while others stay crunchy.
3. Make the garlic cream sauce. In a large saucepan over medium heat, melt the butter. Add the minced garlic and sauté for about a minute until it’s fragrant. Don’t let it burn—burnt garlic is the enemy. Sprinkle in the flour and whisk it together to make a paste (fancy people call this a roux). Cook for another minute while stirring.
4. Add the liquids. Slowly pour in the heavy cream and milk, whisking constantly to avoid lumps. This is where your arm might get a little tired, but push through. Bring the mixture to a gentle simmer and let it thicken for about 3-4 minutes. It should coat the back of a spoon. Add salt, pepper, and thyme. Taste it. Adjust seasonings if needed.
5. Layer time! Arrange about a third of the potato slices in the bottom of your prepared baking dish, overlapping them slightly. Pour about a third of the cream sauce over them. Sprinkle with about a cup of cheese. Repeat this two more times—potatoes, sauce, cheese, potatoes, sauce, cheese. You’re basically building a delicious potato tower. The top layer should be generously covered with cheese because, well, cheese.
6. Cover and bake. Cover the dish tightly with aluminum foil. Pop it in the oven and bake for 45 minutes. The foil keeps the moisture in and prevents the top from burning before the potatoes are tender.
7. Uncover and finish. Remove the foil and bake for another 20-30 minutes until the top is golden brown and bubbly, and a knife slides through the potatoes easily. If you want extra browning on top, turn on the broiler for the last 2-3 minutes. Just don’t walk away—broilers are aggressive and will burn your masterpiece in seconds.
8. Let it rest. I know this is the hardest part. Let the dish sit for about 10-15 minutes before serving. This lets the sauce thicken up and makes it easier to serve without everything sliding around like a potato avalanche.

Common Mistakes to Avoid

Slicing potatoes too thick or too thin. Too thick and they won’t cook through. Too thin and they’ll turn to mush. Aim for that Goldilocks zone of about ⅛ inch. Consistency is key here, people.

Skipping the roux. Some recipes just dump cream on potatoes and call it a day. That’s how you end up with a watery mess. The flour-butter mixture is what thickens everything up and makes it actually creamy instead of soupy.

Not seasoning enough. Potatoes are basically flavor sponges, and if you don’t season your cream sauce properly, you’ll end up with bland potatoes. Taste as you go! This isn’t the time to be shy with the salt and pepper.

Using the wrong potatoes. Russets are ideal because they’re starchy and absorb the cream beautifully. Waxy potatoes like red potatoes won’t give you that same creamy texture. Save those for potato salad.

Burning the garlic. Seriously, watch that garlic like a hawk. It goes from perfect to burnt in like 10 seconds flat. Burnt garlic tastes bitter and will ruin your whole vibe.

Not letting it rest. I get it, you’re hungry and it smells amazing. But if you dig in immediately, it’s gonna be a liquidy disaster. Give it those 10-15 minutes to set up properly.

Alternatives & Substitutions

Can’t find Gruyere? Use all cheddar, or try fontina, Swiss, or even mozzarella. Basically any good melting cheese works. IMO, the cheddar-Gruyere combo is chef’s kiss, but use what you’ve got.

Want to make it lighter? You can swap half the heavy cream for more milk or even half-and-half. It won’t be quite as rich, but it’ll still be tasty. Let’s not pretend it’s healthy though—it’s still scalloped potatoes.

Dairy-free? Use coconut cream or cashew cream with plant-based butter and vegan cheese. I haven’t personally tried this version, but I’ve heard it can work. Your mileage may vary.

Add some protein. Throw in some crispy bacon bits or diced ham between the layers. Turns it into more of a complete meal situation.

Mix up the herbs. Try fresh rosemary instead of thyme, or add some fresh sage. Chives are also fantastic here.

Sweet potato version? Swap half the russets for sweet potatoes. It adds a nice color contrast and a subtle sweetness that’s pretty fantastic.

FAQs

Can I Make This Ahead of Time?

Absolutely! Assemble the whole thing, cover it tightly, and stick it in the fridge for up to 24 hours before baking. Add an extra 10-15 minutes to the covered baking time since it’s starting cold. This is a lifesaver for holiday cooking when your oven space is basically a war zone.

Can I Freeze Scalloped Potatoes?

You can, but I’m gonna level with you—the texture gets a bit weird after freezing. The cream can separate and the potatoes might be a little mushy. If you do freeze it, thaw it completely in the fridge overnight before reheating. Lower your expectations just a smidge.

What’s the Best Way to Reheat Leftovers?

Cover with foil and reheat in a 350°F oven for about 20 minutes until warmed through. Microwave works in a pinch, but the oven keeps everything from getting weird and rubbery. Add a splash of cream or milk if it seems dry.

Can I Use Pre-Shredded Cheese?

Technically yes, but freshly shredded cheese melts so much better. Pre-shredded stuff has anti-caking agents that make it less creamy. If convenience is king for you though, go ahead. No judgment… okay, maybe a little.

How Do I Know When the Potatoes Are Done?

Stick a knife through the center of the dish. If it slides through easily with no resistance, you’re golden. If it feels hard or crunchy, give it more time. Better slightly overcooked than crunchy potatoes.

Can I Use a Different Type of Potato?

Stick with russets or Yukon golds. Red potatoes or fingerlings are too waxy and won’t give you that creamy texture you’re after. This is one time where the type of potato really matters.

Why Is My Sauce Watery?

Probably didn’t cook the roux long enough, or didn’t let the sauce thicken properly before adding it to the potatoes. Make sure that cream mixture is noticeably thicker before you start layering. Also, letting the dish rest after baking helps the sauce set up.
