Mccormick Scalloped Potatoes Recipe: Layered Cheese Crunch Over Creamy Vinegar-Kissed Wedges

This McCormick scalloped potatoes recipe delivers the ultimate comfort food experience—creamy, vinegar-kissed layers topped with a golden cheese crunch. 🌟 Growing up in a Boston triple-decker, I learned that the secret to perfect scalloped potatoes lies in the balance of tangy cream sauce and crispy cheese topping, a technique my Nonna perfected while I stood on a stool watching.

The right spices make all the difference, and McCormick’s garlic powder and onion salt elevate every bite to restaurant-quality.

The process is simpler than it looks: thinly sliced potatoes baked in layers with a rich cream sauce, finished with a blanket of melted cheese.

What sets this recipe apart is the vinegar twist—just a splash of white vinegar brightens the sauce, cutting through the richness while keeping the potatoes tender. The cheese topping isn’t just melted; it’s crisped to a perfect golden-brown, creating that satisfying crunch with every forkful.

This dish is foolproof, whether you’re feeding a family or serving as a side for a holiday meal.

By the time it emerges from the oven, you’ll have a dish that’s creamy, tangy, and irresistibly cheesy—each layer delivering on the promise of New England comfort food.

The aroma alone will have everyone gathering around the table, and the first bite proves why this recipe has been a staple in kitchens for generations. Ready to master this classic? Let’s get started with the ingredients you’ll need.

For those who love variations, try adding crispy bacon between layers or swapping cheddar for Gruyère for a deeper, nuttier flavor. The possibilities are endless, but the foundation—creamy, vinegar-kissed potatoes with that perfect cheese crunch—is what makes this recipe unforgettable.

Ingredients for mccormick scalloped potatoes

Just 12 ingredients—creamy, tangy, and cheesy—transform into New England’s ultimate comfort dish.

The potatoes are the star, so Russets are non-negotiable—they’re starchy enough to hold up to baking without falling apart. Grab the biggest bag you can find at Walmart or Kroger—they’re usually on sale. Slice them thinly (I use a mandoline for even slices), and soak them in cold water for 10 minutes to remove excess starch. That’s what keeps them tender and prevents a gummy texture. The cheese? Sharp white cheddar is the classic choice—it melts beautifully and has that perfect tang. But if you’re feeling fancy, Gruyère from Whole Foods adds a nutty depth that’s worth the splurge.

No heavy cream? Half-and-half plus a splash of milk works in a pinch, but you’ll lose that ultra-rich texture. Pre-shredded cheese? Skip it—it’s coated with anti-caking agents that make the topping dry and crumbly. Fresh thyme is ideal, but if you’re out, dried thyme at half the amount gets you close. The vinegar is key—it’s what gives the sauce that bright, tangy kick. No white vinegar? Apple cider vinegar works just as well. And if you’re baking for a crowd, double the cheese—trust me, it’s worth it.

This dish reheats beautifully—just cover with foil and warm in the oven for 10 minutes. Leftovers keep for 3-4 days in the fridge, though I rarely let it last that long. For make-ahead prep, assemble the dish in a baking dish, cover tightly, and refrigerate for up to 24 hours before baking. The cheese topping gets even crispier if you bake it straight from the fridge. Freeze portions for up to 3 months—just thaw overnight in the fridge before reheating.

Step-by-step instructions for Mccormick scalloped potatoes

Here's how to create the perfect creamy, vinegar-kissed layers that'll have everyone begging for seconds!

First, peel the 3 lbs Russet Potatoes and cut them into ⅛-inch thick slices. I use a sharp mandoline for even slices—this ensures they cook uniformly and create those gorgeous, crispy layers. As you slice, soak the potatoes in cold water for 10 minutes to remove excess starch, then drain and pat completely dry with paper towels. Starchy potatoes make the sauce gummy, and we want that creamy perfection!

In a large bowl, toss the dried potato slices with 1 tbsp White Vinegar, 1 tsp McCormick Garlic Powder, 1 tsp McCormick Onion Salt, and 0.5 tsp Ground Black Pepper. The vinegar brightens the flavor and helps tenderize the potatoes, while the seasonings create that signature tangy-savory depth. Mix gently—you don't want to bruise the delicate slices. Let them sit while you prep the cheese sauce.

In a medium saucepan, melt 4 tbsp Butter over medium heat. Once melted, whisk in 2 tbsp All-Purpose Flour and cook for 1-2 minutes until it forms a smooth paste—that's your roux. This will thicken the sauce beautifully and give it that silky texture.

Slowly pour in the 2 cups Heavy Cream and 1 cup Whole Milk while whisking constantly to prevent lumps. Bring the mixture to a gentle simmer and cook for 3-4 minutes until it thickens slightly. Remove from heat and stir in the 2 cups Sharp White Cheddar Cheese and 0.5 cup Gruyère Cheese until completely melted and smooth. The sauce should be thick enough to coat the back of a spoon but still flow freely.

Preheat your oven to 375°F. Grease a 9x13-inch baking dish generously with butter—this prevents sticking and makes cleanup a breeze. Start by spreading half of the potato slices in a single layer on the bottom of the dish, slightly overlapping them. Pour about half of the cheese sauce over the potatoes, then sprinkle with half of the 1 tbsp Fresh Thyme Leaves.

Repeat with the remaining potato slices and cheese sauce, finishing with the last layer of potatoes. The top layer should be potatoes only—this ensures they get that perfect golden-brown crust. Here's the thing—press down gently on each layer as you go. This prevents the potatoes from floating and creates those beautiful, crispy layers we all love.

Cover the baking dish tightly with aluminum foil and bake for 45 minutes. This initial covered bake allows the potatoes to cook through and absorb the creamy sauce without over-browning. After 45 minutes, remove the foil and bake for another 15-20 minutes until the top is golden brown and bubbly.

You'll know it's done when the edges are crispy and the cheese on top has turned a beautiful golden hue. If the top starts to brown too quickly, tent it loosely with foil to prevent burning. Let the scalloped potatoes rest for 10 minutes before serving—this allows the layers to set and makes slicing much easier. The result? Creamy, tangy, cheesy layers with that perfect crispy top that'll have everyone reaching for seconds!

Essential equipment for mccormick scalloped potatoes

Must-Have Baking Dish

You’ll need a 9x13-inch baking dish—this is non-negotiable for even cooking and that signature layered look. I’ve tried glass, ceramic, and stainless steel, but glass (like Pyrex) is my top pick because it distributes heat evenly and prevents hot spots.

A well-seasoned Lodge cast iron skillet also works if you’re feeling adventurous, but it requires extra greasing to prevent sticking. Avoid thin metal pans—they’ll cause uneven browning and a soggy top. 🔥

Layering Tools

A sharp mandoline slicer is your best friend for achieving those perfect ⅛-inch potato slices. I use the OXO Good Grips model—it’s affordable, safe, and does the job without bruising the potatoes.

If you don’t own one, a serrated knife and a steady hand work too, but expect uneven slices. For pressing down layers, I keep a small, flat-bottomed glass or spatula handy to create that tight, crispy texture. No fancy tools?

A clean mason jar or rolling pin works in a pinch.

Thermometer for Precision

An instant-read thermometer (like the Thermoworks ThermoPop) is worth its weight in gold for checking the internal temperature of your potatoes. Aim for 205–210°F—this ensures they’re tender but not mushy. I also use a digital oven thermometer (like the Kizen) to verify my oven’s actual temperature.

Ovens run hot or cold, and this small investment prevents under- or overcooked potatoes. No thermometer? The toothpick test works: insert a toothpick into the center—it should slide in easily with slight resistance.

Cheese Prep Essentials

Skip the pre-shredded cheese—it’s coated with anti-caking agents that make the topping dry and crumbly. Instead, buy a block of sharp white cheddar and shred it yourself using the large holes on a box grater.

For extra convenience, I keep a food processor with a grating attachment on hand—it’s faster and more consistent. If you’re adding Gruyère, shred it separately and toss it into the sauce last to avoid clumping.

A fine-mesh sieve also helps remove any stray potato starch from the shredded cheese before layering. 🧀

Vinegar & Spice Measuring

Precision matters with the white vinegar and McCormick spices—these are the flavor anchors of the dish. I measure the 1 tbsp vinegar using a small liquid measuring cup for accuracy, and the spices with a spice scoop (not a teaspoon from your spice jar).

A mortar and pestle comes in handy if you’re grinding fresh black pepper for that extra bite. For thyme, I snip the leaves directly into the dish with sharp kitchen shears—it’s faster than chopping and avoids wasting stems.

Keep a small bowl nearby to collect any stray thyme leaves for garnishing.

Make-Ahead Gear

If you’re prepping ahead, airtight containers are a must for storing the assembled dish in the fridge. I use glass Pyrex containers with snap-on lids—they’re sturdy and microwave-safe. For freezing, quart-sized freezer bags (like Ziploc) work best—they’re flat, stackable, and prevent freezer burn.

Label everything with the date and recipe name (trust me, you’ll thank yourself later). A parchment paper-lined tray also helps when baking straight from the freezer—it catches any drips and makes cleanup easier. ❄️
