Description

These Sheet Pan Scalloped Potatoes are a rich and cheesy twist on the classic side dish, baked to golden perfection in a thin, even layer. Infused with garlic, thyme, and a blend of cheddar and Parmesan cheeses, each bite delivers crispy edges, creamy centers, and irresistible flavor. Perfect for feeding a crowd or pairing with roasted meats and veggies.

Ingredients

Scale

  • 2 lbs Yukon Gold potatoes, thinly sliced (about 1/8 inch thick)

  • 1 cup heavy cream

  • 1 cup whole milk

  • 3 cloves garlic, minced

  • 1 small onion, thinly sliced

  • 2 cups shredded sharp cheddar cheese

  • 1/4 cup grated Parmesan cheese

  • 1 tsp fresh thyme leaves (plus more for garnish)

  • Salt and freshly ground black pepper, to taste

  • 2 tbsp unsalted butter, cut into small cubes

Instructions

1. Preheat and Prep

  • Preheat your oven to 400°F (200°C).

  • Lightly grease a large sheet pan (approx. 12×17 inches) with nonstick spray or butter.

2. Make the Cream Sauce

  • In a medium saucepan, combine heavy cream, milk, garlic, and a pinch of salt and pepper.

  • Heat over medium until the mixture starts to bubble—do not boil. Set aside.

3. Layer the Potatoes

  • On the prepared sheet pan, layer potato slices and onions in slightly overlapping rows.

  • Sprinkle each layer with salt, pepper, thyme, and a handful of cheddar cheese.

  • Repeat until all the potatoes and onions are used. Reserve some cheddar and Parmesan for topping.

4. Add the Cream

  • Gently pour the warm garlic cream mixture over the layered potatoes to coat evenly.

5. Top and Bake

  • Dot the top with pieces of butter.

  • Sprinkle remaining cheddar and Parmesan cheese on top.

  • Bake uncovered for 40–45 minutes or until the top is golden and bubbly, and potatoes are fork-tender.

  • If browning too quickly, cover loosely with foil during the last 10–15 minutes.

6. Rest and Serve

  • Let rest for 10 minutes before serving to allow the layers to firm up.

  • Garnish with fresh thyme for a pop of color and flavor

Notes

  • This sheet pan version of scalloped potatoes speeds up cooking while maximizing flavor and crispiness.

  • Ideal for weeknight dinners, holiday meals, or potluck gatherings.
