How to Make Scalloped Potatoes

Nothing beats a good scalloped potato recipe when you’re looking for that perfect comfort food side dish. Johnny Mac from The Sauce and Gravy Channel shares his foolproof method that creates the creamiest, cheesiest potatoes you’ve ever tasted – the kind that disappear fast at family gatherings.

His technique focuses on building an amazing cheese sauce from scratch that won’t curdle or turn oily like so many recipes do. With simple ingredients like butter, flour, milk, cream, and sharp cheddar cheese, he shows how to layer everything perfectly for golden, bubbly results that work just as well for Sunday dinner as they do for Thanksgiving.

Key Takeaways

• The secret is making a thick roux-based cheese sauce that stays creamy and never breaks in the oven
• Layer thinly sliced russet potatoes with the sauce in thirds for even coverage throughout
• Bake at 350°F for one hour until golden and crusty on top with tender potatoes inside

Easy Butter and Flour Base

Simple Roux Steps Without Stress

Johnny Mac knows that getting the butter and flour mixture right makes all the difference. He starts with 3 tablespoons of butter in a saucepan over medium heat.

Once that butter melts down nice and smooth, he adds 3 tablespoons of flour right into the pan. The key here is cooking this mixture for 2 to 3 minutes. This step gets rid of that raw flour taste that nobody wants in their cheese sauce.

Pro tip: Don’t rush this part! Those few minutes of cooking really matter for flavor.

Creating the Perfect Thick Consistency

Here’s where Johnny Mac adds the liquid ingredients that transform everything. He pours in:

• 1/2 cup milk (125 ML)
• 1 cup cream (250 ML)

He chooses more cream than milk because he wants that extra creamy texture. Smart move!

The whisking starts right away. Johnny Mac warns not to walk away because this sauce thickens up fast. He reminds everyone that this sauce is supposed to get really thick. Don’t panic when it happens!

This isn’t like a thin gravy – it needs to be thick enough to coat those potato layers perfectly.

Adding the Sharp Cheddar

Once the sauce reaches that perfect thick consistency, Johnny Mac turns the heat down low. Time for the star ingredient!

He adds 1 cup of grated sharp cheddar cheese (about 90 grams). The whisk comes out again to mix that cheese until it melts completely into the sauce.

The sauce should look:

• Rich and creamy
• Thick enough to coat a spoon
• Smooth without lumps

Johnny Mac takes a moment to taste and adjust. A little salt and pepper can make all the difference. This homemade sauce beats those store-bought packets every single time!

Getting Your Potatoes Ready the Right Way

Picking and Cutting Your Russet Potatoes

Johnny Mac swears by russet potatoes for this recipe, and honestly, there’s a good reason why. These sturdy spuds hold their shape beautifully and soak up all that creamy goodness without turning to mush.

He uses about five medium russet potatoes (that’s roughly 4 cups sliced or 700 grams). Start by peeling those potatoes nice and clean. Then comes the slicing part – and this matters more than you might think!

Cut each potato into 1/4-inch thick slices (about 6mm if you’re using a metric ruler). Try to keep them all the same thickness so they cook evenly. Nobody wants some pieces still crunchy while others are falling apart.

Mom tip: If your knife skills aren’t quite there yet, a mandoline slicer works wonders here. Just watch those fingers!

The Secret Water Soak for Perfect Results

Here’s where Johnny Mac shares a little trick that makes all the difference. After you slice those potatoes, don’t just throw them straight into the dish.

Instead, give them a 5-minute bath in plain water. This simple step helps remove extra starch and keeps your potatoes from getting too sticky or gummy in the oven.

Once their little spa treatment is done, pat them completely dry with a clean kitchen towel. This step is important – wet potatoes won’t layer nicely and can make your sauce watery.

The process is simple:

• Slice potatoes
• Soak for 5 minutes
• Pat dry thoroughly
• Ready to layer

Building Your Layers the Old-Fashioned Way

Now comes the fun part – putting it all together just like the grandmas used to do. Johnny Mac keeps it simple with his layering technique.

First, butter your 8×8 inch baking dish really well. This prevents sticking and adds a little extra richness.

Start with one layer of potatoes on the bottom. Arrange them so they overlap slightly but don’t worry about making it perfect. Then add about one-third of your creamy cheese sauce over this first layer.

As Johnny Mac says, this first layer doesn’t need to be picture-perfect. Just try to cover most of the potatoes with that lovely sauce.

Next, add the remaining sliced potatoes to fill up the dish. Now comes the final sauce layer – and this one gets the royal treatment.

Drop little dollops of sauce all over the top, then spread it around like you’re frosting a birthday cake. Use a spoon or spatula to get into every nook and cranny. Every potato deserves some of that creamy goodness.

For families who like a little heat, Johnny Mac suggests sprinkling some cayenne pepper on top. And if you want to go all out, add an extra 1/4 cup of sharp cheddar right on top for that gorgeous golden crust.

Building Your Creamy Potato Casserole

Preparing Your Baking Dish

Johnny Mac knows that nothing ruins a perfect casserole like potatoes stuck to the bottom of the dish. He grabs an 8-inch by 8-inch baking dish and butters it up really well.

This little step makes all the difference when you’re trying to serve up neat portions later. Your family will thank you for this simple touch that keeps everything looking pretty on their plates.

Creating Those Perfect Creamy Layers

Now comes the fun part – building those gorgeous layers that make this dish so special. Johnny starts with his sliced russet potatoes that he’s already prepped and dried off.

He makes one even layer of potatoes across the bottom of that buttered dish. Then he adds about a third of his rich cheese sauce right on top.

First Layer Tips:

• Don’t worry about making the sauce coverage perfect
• Just try to hit most of the potatoes with that creamy goodness
• Think of it like you’re tucking the potatoes into bed

Next, he adds all the remaining sliced potatoes to the dish. Then comes the best part – adding the rest of that amazing cheese sauce on top.

Johnny treats this just like frosting a cake. He puts little dollops of sauce all over the potatoes, then uses a spoon or spatula to spread it around everywhere.

Top Layer Secrets:

• Try to hit every nook and cranny
• This sauce will protect your potatoes in the oven
• Take your time – this layer shows on the final dish

Adding That Special Touch

Here’s where Johnny gets a little playful with his comfort food classic. He sprinkles some cayenne pepper right over the top of that creamy sauce.

This step is totally up to you – some families love a tiny kick, while others prefer things mild. The cayenne just wakes up all those rich flavors without making things too spicy.

To really put this dish over the top, he adds a final 1/4 cup of grated sharp cheddar cheese across the surface. This creates that beautiful golden crust that makes everyone’s mouth water.

Your casserole is now ready for its hour-long bake at 350 degrees Fahrenheit. That’s when the real magic happens in your oven.

Getting That Perfect Golden Finish

Creating the Crispy Cheese Top

The magic happens when Johnny Mac adds that final touch of cheese on top. He sprinkles a quarter cup of sharp cheddar right over the sauce before baking.

This extra cheese layer does something wonderful in the oven. It melts and then gets golden brown, creating that perfect crispy crust we all love.

Pro tip for busy moms: You can prep this whole dish earlier in the day and just add that final cheese layer right before baking. It’s a real time-saver when you’re juggling multiple dishes for dinner.

The key is using sharp cheddar for both the sauce and the topping. Johnny Mac knows this cheese gives the best flavor and melts beautifully without getting oily.

Getting the Cook Time Just Right

Johnny Mac bakes his scalloped potatoes at 350 degrees for exactly one hour. This timing is perfect for getting tender potatoes without overcooking.

Here’s what to look for when they’re done:

• Golden brown crust on top
• Bubbling around the edges
• Potatoes feel tender when you poke them with a fork
• The sauce looks creamy, not watery

After that full hour, Johnny Mac’s dish comes out with a gorgeous golden top that’s not burnt. The potatoes underneath are soft and moist, and that cheese sauce stays perfectly creamy.

Little kitchen wisdom: If your top is browning too fast, just tent some foil over the dish for the last 15 minutes. Every oven runs a bit different, so trust your eyes more than the timer.

The real test comes when you dig in with that spoon. Johnny Mac shows how it should break through that crusty top layer easily, revealing those perfectly cooked potatoes swimming in rich, unbroken cheese sauce underneath.

Creating Your Family’s New Favorite Side

Making Sure Your Potatoes Are Perfect

Johnny Mac shows us how to tell when these golden beauties are ready to come out of the oven. After that full hour of baking, he looks for a lovely golden crust on top.

The real test comes when you gently press a spoon through that gorgeous crusty layer. The potatoes should give way easily, soft and tender all the way through.

Signs your scalloped potatoes are done:

• Golden brown top that’s not burnt
• Spoon slides through easily
• Potatoes feel soft when pressed
• Sauce bubbles around the edges

If your potatoes still feel firm when you test them, pop that dish back in the oven for another 10-15 minutes. Every oven is a little different, and some potatoes are just more stubborn than others!

Cutting and Presenting Your Masterpiece

Johnny Mac makes serving look effortless, but there’s definitely a technique to getting those perfect portions. Let the dish rest for about 5 minutes after it comes out of the oven. This gives everything time to set up nicely.

Use a large spoon or serving spatula to cut through that beautiful crusty top. The sauce should be creamy and rich, holding everything together without being runny.

Best serving tips:

• Let it cool for 5 minutes before serving
• Use a wide spoon or spatula
• Scoop deep to get all the layers
• Expect the first piece to be a little messy

The first serving always looks a bit rustic, but that’s part of the charm! Each spoonful should have tender potatoes covered in that dreamy cheese sauce. Johnny Mac describes it perfectly – it’s pure comfort food heaven that’ll have your family asking for seconds before they’ve finished their firsts.
