Ingredients for joanna gaines scalloped potatoes

Just twelve ingredients transform into Joanna Gaines' iconic crispy-cheesy scalloped potatoes.

The potatoes are non-negotiable—Russets slice the thinnest, giving you that perfect creamy texture. Whole Foods or Trader Joe's carry the best for this, but any grocery store will do. Peeled and sliced evenly (about 1/8-inch thick), they layer beautifully. For cheese, aged sharp cheddar is key—Cabot or Tillamook are my go-tos, but any sharp cheddar with visible crystals works. The cornmeal topping? Bob's Red Mill fine grind is ideal, but any fine cornmeal will give you that signature crunch. Don't skip the bacon if you're feeling fancy—it adds a smoky depth that pairs perfectly with the creamy layers.

No sharp cheddar? Gruyère or Monterey Jack work in a pinch, but the flavor won't be quite the same. Fresh thyme out of season? Dried at one-third the amount gets you close. The bacon can be swapped for crumbled sausage or pancetta if you prefer. For the cornmeal topping, if you're out, crushed Ritz crackers add a buttery crunch. The butter matters here—unsalted, high-fat content ensures that rich, velvety texture. If you're watching calories, you can reduce the butter slightly, but trust me on the full-fat version for that homestyle taste.

Prep the potatoes ahead and store them in cold water in the fridge for up to 24 hours—this keeps them from browning. The cheese sauce can be made a day ahead and reheated gently before layering. Once baked, these keep beautifully in the fridge for 3-4 days, though they're best the first day. For leftovers, reheat covered at 350°F for 15 minutes—the top will crisp up again. Freeze portions for up to 2 months by wrapping tightly in foil. The cornmeal topping gets extra crispy when reheated, so it's worth the effort.

Step-by-step instructions for Joanna Gaines' scalloped potatoes

Here's how to create those golden, crispy cornmeal crowns with rich, creamy cheese layers—just like Joanna makes them.

Preheat your oven to 375°F. Peel and thinly slice the 2.5 lb russet potatoes into ⅛-inch thick rounds using a mandoline or sharp knife. You should end up with about 8-10 slices per potato. Soak the slices in cold water for 10 minutes to remove excess starch, then drain and pat completely dry with paper towels.

In a medium saucepan, melt the ½ cup butter over medium heat. Add the minced garlic cloves and sauté for 30 seconds until fragrant but not browned. Pour in the ½ cup warmed whole milk, 1 cup heavy cream, and 1.5 tsp salt. Bring to a gentle simmer and let it cook for 5 minutes until slightly thickened. Remove from heat and stir in the 1.5 cups shredded sharp cheddar cheese and 1 tsp dried thyme until fully melted and smooth.

Lightly grease a 9x13-inch baking dish with butter. Begin by spreading a thin layer of the cheese mixture on the bottom of the dish. Arrange a single layer of potato slices on top, slightly overlapping them. Sprinkle evenly with ½ cup cornmeal and ½ tsp black pepper, pressing gently to adhere. Repeat with another layer of cheese mixture, followed by another layer of potatoes and cornmeal.

Here's the thing—don't overcrowd the layers. You want about 3 layers total, with each layer getting its own cornmeal dusting. The cornmeal creates that signature crispy texture on top while keeping the potatoes tender inside. If you use all the cornmeal at once, you'll miss the magic of those individual crispy crowns.

Cover the baking dish tightly with aluminum foil and bake for 45 minutes. After this initial bake, remove the foil and increase the oven temperature to 400°F. Bake uncovered for another 20-25 minutes until the top is deep golden brown and the edges are bubbling. You'll know it's perfect when the cornmeal crowns look crispy and the cheese on top has turned a beautiful golden color.

Real talk: If the top isn't browning enough, broil for 1-2 minutes at the end, watching closely to avoid burning. The potatoes should be tender when pierced with a fork, but still hold their shape. If they feel too soft, they've been overbaked—this is why the cornmeal layer matters so much for that crispy contrast.

If you're using the 4 oz bacon, cook it in a separate skillet until crispy, then crumble it over the top of the scalloped potatoes in the last 5 minutes of baking. This adds a smoky, salty contrast that takes these potatoes to the next level. If you skip the bacon, just let the dish rest for 10 minutes before serving to let the layers set.

Serve immediately with the crispy cornmeal crowns on top and the creamy cheese layers underneath. Each bite should deliver that perfect balance of textures—crispy top, creamy middle, and tender potatoes. Leftovers? They're even better the next day, but trust me, you won't have any.

Regional styles of joanna gaines scalloped potatoes

Southern Rustic Style

In the Deep South, scalloped potatoes often take on a heartier, more robust profile. I’ve seen Southern versions use bacon grease instead of butter for the cheese sauce, adding a smoky depth that pairs beautifully with the creamy layers.

The key here is to brown the bacon first, then use the rendered fat to sauté the garlic before making the sauce. This technique infuses the entire dish with that unmistakable Southern flavor. 🥓

Another regional touch is the addition of collard greens or kale, finely chopped and layered between the potato slices. This adds a subtle earthiness that complements the richness.

For an extra Southern flair, some cooks sprinkle hot sauce or crushed red pepper flakes on top before baking—just ½ teaspoon is enough to add a gentle kick without overpowering the dish.

New England Creamy Twist

Up north, scalloped potatoes often lean into heavier cream and more cheese, creating a dish that’s almost like a baked potato casserole. I’ve made a New England version using half-and-half instead of heavy cream, along with Gruyère cheese for a nutty, complex flavor.

The technique is similar, but the sauce is thicker and richer—almost like a cheese fondue consistency. This works especially well if you’re serving it as a main dish alongside roasted vegetables.

For an authentic New England touch, some recipes call for a splash of bourbon—about 1 tablespoon—folded into the cheese sauce. This adds a warm, caramel-like note that pairs perfectly with the crispy cornmeal top.

The bourbon also helps deepen the flavors during baking, making each bite more flavorful. 🥃

Midwest Homestyle Classic

The Midwest approach to scalloped potatoes is all about simplicity and comfort. Here, you’ll often find potatoes sliced even thinner—sometimes just ⅛-inch thick—and the cheese sauce is lighter, using whole milk instead of cream to keep it from being too heavy.

The cornmeal topping is still essential, but some cooks add a touch of flour to the cornmeal mixture for extra crispiness.

What sets Midwest scalloped potatoes apart is the use of local cheeses, like Colby or Monterey Jack, which are easier to find in grocery stores across the region. These cheeses melt smoothly and add a mild, slightly sweet flavor that’s perfect for family dinners.

For a true Midwest touch, some recipes include a sprinkle of paprika on top before baking—just ¼ teaspoon—to give the dish a subtle, warm hue and a hint of smokiness.

Pacific Northwest Crispy Edge

Out West, scalloped potatoes often take on a lighter, fresher profile, with an emphasis on crispy edges and bright flavors. I’ve seen Pacific Northwest versions use almond flour instead of cornmeal for the topping—it adds a delicate nuttiness that pairs well with the creamy cheese.

The cheese sauce is also lighter, sometimes using Greek yogurt mixed into the cream for extra tang.

For a regional twist, some cooks incorporate fresh herbs like chives or dill, finely chopped and sprinkled between the layers. This adds a bright, fresh contrast to the richness of the cheese.

The baking technique here is slightly different too—some prefer to bake at 350°F for a longer time (50-60 minutes) to ensure the edges are extra crispy while keeping the center tender. This works especially well with wild-caught salmon or grilled trout as a main course.
