Cheesy Scalloped Potatoes

Cheesy Scalloped Potatoes are thinly sliced russet potatoes cooked in a creamy garlic-onion sauce with fresh thyme, then layered with shredded cheddar and Parmesan cheeses. The casserole bakes to a bubbly, golden crust with tender and flavorful potato layers, making it a comforting side dish with rich cheese and herb notes.

Description

This recipe begins by sautéeing pressed garlic and minced onions with fresh thyme in butter until fragrant and softened. Heavy cream and chicken broth are added to create a rich cooking liquid. Thinly sliced russet potatoes and bay leaves are simmered in the cream until nearly tender, absorbing the aromatic flavors. Half of this creamy potato mixture is spooned into a baking dish and topped with shredded cheddar and Parmesan cheeses. The remainder is added atop the cheese layer, followed by more Parmesan and cheddar on top.

After chilling to allow flavors to meld and firm up, the scalloped potatoes bake uncovered at 350°F until the cheese melts and browns, and the cream bubbles around the edges. The final dish presents as a layered casserole with a golden crust and tender, flavorful potato layers seasoned with garlic, thyme, and cheese.

This side dish pairs well with roasted or grilled meats and can be prepared ahead for convenience. Letting the dish rest after baking helps the sauce thicken for easier serving.

Inspired by Cooks Illustrated's New Best Recipe, this approach balances creamy sauce with herbaceous notes and rich melting cheeses for a classic potato gratin experience.

  • 2 tablespoons thyme fresh leaves
  • salt Kosher salt and freshly ground
  • black pepper Kosher salt and freshly ground
  • 2 cups heavy cream

  3. Transfer half of the mixture to a 1 ½ quart dish, an 8x8 or 9x6-inch baking dish. Sprinkle with half of the cheese. Top with the remaining potato mixture, sprinkle with the remaining parmesan cheese then top with the remaining cheddar cheese.
  4. Refrigerate for 1 hour or up to overnight.

Notes

  • This recipe is adapted from Cooks Illustrated The New Best Recipe.
  • Press garlic cloves for even flavor release and a smooth sauce.
  • Simmering potato slices in cream and broth softens them before baking, reducing cook time and ensuring tender layers.
  • Refrigerate assembled dish for at least an hour before baking to develop flavor and firm up layers.
  • Let the baked scalloped potatoes rest for 5-10 minutes before serving to thicken the sauce.
