What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry or fridge staples, making it easy to whip up whenever the craving hits.

• Potatoes: 3 pounds Yukon Gold or Russet potatoes, peeled and thinly sliced (about 1/8 inch thick). Yukon Golds give a creamy texture, Russets hold shape nicely.
• Butter: 4 tablespoons unsalted butter, divided (adds richness and helps create that crispy top).
• Garlic: 2 cloves fresh garlic, minced (for that subtle savory punch).
• All-purpose flour: 3 tablespoons (helps thicken the creamy sauce).
• Milk: 2 cups whole milk, warmed (for a silky sauce; use dairy-free milk if needed).
• Heavy cream: 1 cup (boosts creaminess and richness).
• Cheese blend: 2 cups shredded sharp cheddar and 1 cup shredded Gruyère (adds depth and meltiness).
• Parmesan cheese: ½ cup grated (sprinkled on top for a golden crispy crust).
• Nutmeg: ¼ teaspoon freshly grated (optional but adds a warm subtle note).
• Salt and freshly ground black pepper: to taste (season generously!).
• Fresh thyme or chives: 1 tablespoon chopped, for garnish (optional, but fresh herbs brighten the dish).

If you want to switch things up, use Gruyère alone for a nuttier flavor or swap cheddar for a mild mozzarella if you like it less sharp. For gluten-free, substitute the all-purpose flour with cornstarch or a gluten-free blend. And yes, the potatoes must be sliced thinly—this is key for that tender, melt-in-your-mouth texture!

Equipment Needed

• Mandoline slicer or sharp chef’s knife: for uniformly thin potato slices. I prefer a mandoline for speed and consistency, but a steady hand with a knife works too.
• Large mixing bowl: to toss potatoes and prepare the sauce.
• Medium saucepan: to make the creamy cheese sauce.
• 9×13-inch baking dish: a classic casserole dish works perfectly for layering the potatoes.
• Wooden spoon or whisk: to stir the sauce smoothly without lumps.
• Aluminum foil: for covering the dish during baking to prevent burning.

If you don’t have a mandoline, slice potatoes as thin and even as possible to avoid uneven cooking. For budget-friendly options, a simple glass baking dish works just fine. Regular maintenance on your mandoline’s blade (keep it sharp!) means fewer accidents and perfectly sliced potatoes every time.

Preparation Method

1. Preheat your oven to 350°F (175°C). Butter the 9×13-inch baking dish well to keep those potatoes from sticking.
2. Prepare the potatoes: Using a mandoline or sharp knife, slice your peeled potatoes into thin rounds—about 1/8 inch thick. Place them in cold water briefly to rinse off excess starch, then drain and pat dry with a clean towel. This step helps avoid gummy potatoes later.
3. Make the roux-based cream sauce: In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add minced garlic and sauté for about 1 minute until fragrant but not browned. Sprinkle in the flour and whisk constantly for 2 minutes to cook the raw taste out.
4. Slowly add warm milk and cream: whisk continuously to avoid lumps. Bring to a gentle simmer, stirring frequently until the sauce thickens, about 5-7 minutes. You want a thick but pourable consistency that will cling to the potatoes.
5. Remove from heat and stir in the cheese: Add the shredded cheddar and Gruyère gradually, stirring until melted and smooth. Season with salt, pepper, and nutmeg. Taste and adjust seasoning—it should be rich and flavorful.
6. Layer the potatoes: Arrange a single layer of potato slices in the prepared baking dish, slightly overlapping. Pour a ladle of the cheese sauce over them, then repeat layering potatoes and sauce until all are used, finishing with sauce on top.
7. Top with Parmesan and remaining butter: Sprinkle grated Parmesan evenly over the surface and dot with the remaining 2 tablespoons of butter for that ultra-crispy, golden crust.
8. Cover and bake: Cover the dish tightly with aluminum foil and bake for 45 minutes. Then remove the foil and bake uncovered for another 25-30 minutes until the top is bubbly and deeply golden brown.
9. Rest before serving: Let the scalloped potatoes rest for 10-15 minutes. This helps the sauce thicken and makes serving cleaner.
10. Garnish and enjoy: Sprinkle with chopped fresh thyme or chives for a pop of color and fresh flavor before serving.

If you notice the top browning too quickly, tent it loosely with foil during the last bake. And if the sauce looks too thick before baking, whisk in a splash of milk to loosen it up.

Cooking Tips & Techniques

Here’s the real deal on making creamy crispy scalloped potatoes au gratin that impress every time. First off, slice your potatoes uniformly thin. Uneven slices lead to some parts undercooked while others turn mushy. Trust me, I learned that the hard way (and wasted a batch).

Whisking your flour into melted butter before adding milk is crucial to avoid lumps. Patience during sauce thickening pays off—don’t rush it, or you’ll end up with a watery mess. I like to keep the sauce on medium to low heat for a nice, smooth finish.

Covering the dish while baking traps steam, cooking potatoes through without drying out the top. Then, removing the foil lets the cheese crisp up beautifully. Timing here is key—too long covered, and the top won’t brown; too short, and the potatoes might be underdone.

And hey, if you’re multitasking in the kitchen, prep your potatoes and sauce ahead and refrigerate. Just bring the dish to room temp before baking to ensure even cooking. Also, try to resist digging in right out of the oven—letting it rest makes all the difference in texture.

Variations & Adaptations

Want to mix things up with your creamy crispy scalloped potatoes au gratin? Here are a few ideas:

• Vegetarian twist: Add sautéed mushrooms and caramelized onions between layers for a deep, savory flavor boost.
• Gluten-free: Use cornstarch or a gluten-free flour blend instead of all-purpose flour to thicken the sauce.
• Herb-infused: Swap nutmeg for a pinch of smoked paprika and add fresh rosemary or thyme to the sauce for a fragrant punch.
• Dairy-free: Try coconut cream or cashew cream with a dairy-free cheese alternative. It’s surprisingly tasty and creamy!
• Cheese swap: Experiment with fontina or mozzarella instead of cheddar for a milder, gooey melt.

Personally, I once added a layer of thinly sliced sweet potatoes for a subtle sweetness that balanced the richness. It was a happy accident but totally worth trying if you like a twist.

Serving & Storage Suggestions

Serve these scalloped potatoes hot, right out of the oven, ideally with a sprinkle of fresh herbs to brighten the presentation. They pair beautifully with roasted meats, green beans, or a crisp salad to cut through the richness.

Leftovers? No problem. Store them covered in the refrigerator for up to 4 days. When reheating, cover with foil and warm at 350°F (175°C) until heated through—this keeps the top from burning while warming evenly.

You can also freeze portions in an airtight container for up to 3 months. Thaw overnight in the fridge before reheating. The flavors actually deepen after a day or two, so sometimes I make this ahead of time to serve at gatherings.
