Why These Sheet Pan Scalloped Potatoes Are a Game Changer

• Even Cooking: The thin layers of potatoes cook evenly on a sheet pan, avoiding undercooked spots found in deep dishes.
• Crispy Edges: Every bite has the perfect balance of creamy insides and crispy-cheese-topped edges.
• Quick Assembly: Using a mandoline saves tons of prep time, slicing your potatoes perfectly thin in minutes.

• Versatile Flavor: This recipe blends fresh thyme, garlic, and three cheeses for an elevated yet approachable taste.

Essential Ingredients for Perfect Sheet Pan Scalloped Potatoes

Let’s talk about the ingredients that make these easy scalloped potatoes absolutely shine:

• Yukon Gold Potatoes: These are my go-to because they’re buttery and hold their shape well during baking. If you’re in a pinch, Russets work too but may break down a bit more.
• Gruyere Cheese: This cheese adds a nutty depth that takes the flavor to the next level. If you don’t have Gruyere, Swiss cheese is a good backup.
• Heavy Cream: Provides that luxurious, velvety sauce. Half-and-half could work in a pinch, but the richness won’t be quite the same.
• Fresh Thyme: The vibrant herbal note from fresh thyme truly elevates this dish. Dried thyme can work, but reduce the amount by half.

Ingredients for Sheet Pan Scalloped Potatoes

• 1 cup shredded Gruyere cheese
• 1 cup shredded extra sharp white cheddar cheese
• ⅓ cup freshly grated Pecorino cheese
• 2 cups heavy cream
• 3 cloves garlic, minced
• 1 tablespoon chopped fresh thyme leaves
• 2 teaspoons Dijon mustard
• Kosher salt and freshly ground black pepper, to taste
• 3 pounds Yukon gold potatoes, scrubbed and cut into 1/8-inch thick slices
• 2 tablespoons chopped fresh chives

Step-by-Step Sheet Pan Scalloped Potatoes Instructions

1. Preheat your oven to 450°F. Lightly oil a baking sheet or coat it with nonstick spray to prevent sticking.
2. In a medium bowl, toss together the Gruyere, white cheddar, and Pecorino cheeses. Set aside.
3. In a small saucepan over medium heat, combine heavy cream, garlic, thyme, Dijon mustard, 1 teaspoon salt, and 1/2 teaspoon pepper. Warm until it just begins to boil, then reduce the heat to simmer for 2 minutes. Turn off the heat.
4. Arrange half of the potato slices in a single, overlapping layer on the prepared baking sheet. Sprinkle half of the cheese mixture evenly over the potatoes.
5. Top with the remaining potato slices, layering them in the same manner. Pour the warmed cream mixture evenly over the top.
6. Cover the pan tightly with foil and bake for about 20 minutes, until the potatoes are just tender.
7. Carefully remove the foil and sprinkle the remaining cheese mixture over the potatoes. Return to the oven, uncovered, and bake for another 20 to 25 minutes until the cheese is golden and bubbling.
8. Remove from the oven and let the dish rest for 10 minutes. This helps the sauce thicken and makes serving much easier.
9. Garnish with fresh chopped chives if desired, and serve while hot.

Expert Tips for the Best Sheet Pan Scalloped Potatoes

• Use a Mandoline: Cutting the potatoes into uniform slices ensures they cook evenly, and a mandoline makes this quick and simple.
• Don’t Skip the Covering: Covering the pan for the first half of baking helps the potatoes soften properly before browning.
• Layer Thoughtfully: Overlap your potato slices slightly for even cooking and a beautiful presentation.
• Rest Before Serving: Letting the dish sit for 10 minutes helps the sauce thicken, ensuring clean slices and less mess.
• Fresh Herbs Make a Difference: Swap in oregano or rosemary for subtle flavor variations, or stick with thyme for a classic touch.

Delicious Sheet Pan Scalloped Potatoes Variations

• Bacon Lovers: Add crispy bacon crumbles between the potato layers for extra savory goodness.
• Veggie Boost: Toss in thinly sliced zucchini or sautéed leeks for added flavor and texture.
• Dairy-Free Option: Use coconut milk and a vegan cheese blend to make this dish dairy-free.
• Spicy Twist: Add a pinch of cayenne or red pepper flakes to the cream mixture for a subtle kick.
