There’s nothing more comforting than digging into a dish of tender, cheesy scalloped potatoes. When you let them slow-cook all day, they become even more irresistible.
This recipe gently infuses garlic and fresh thyme, resulting in a crowd-pleasing side that’s so easy, it practically cooks itself.

Ingredients
- 3 pounds russet or Yukon Gold potatoes, peeled and thinly sliced
- 1 small onion, thinly sliced
- 3 garlic cloves, minced
- 1 cup shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 1 cup half-and-half or heavy cream
- 2 tablespoons unsalted butter, softened
- 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
- 1 teaspoon salt
- ½ teaspoon black pepper

Instructions
Begin by preparing your slow cooker. Lightly coat the inside with the softened butter, ensuring every surface is covered. Arrange a third of the sliced potatoes in the bottom of the slow cooker, then sprinkle with a few onion slices, some garlic, a pinch of thyme, salt, and pepper. Follow with a generous handful of cheddar and mozzarella.

Build two more layers the same way: potatoes, onion, garlic, seasonings, and cheese. Finish by slowly pouring the half-and-half or heavy cream over the top, allowing it to seep between the layers. Cover the slow cooker and set it on low for about 6 to 7 hours, or until the potatoes are fork-tender and the cheese is bubbling.
For a beautiful golden crust, uncover and switch your slow cooker to its “high” setting for an additional 15 minutes. Let the scalloped potatoes rest for about 5 minutes to help the sauce thicken before serving piping hot.
Slipping a spatula under the potatoes, plate up generous servings as a holiday side or a comforting companion to simple roasted meats or hearty salads.
Once ready, garnish with a few extra thyme leaves for a fresh and vibrant touch.

Whether you’re treating a houseful of hungry guests or looking for a cozy weeknight dinner addition, these creamy garlic and thyme scalloped potatoes are the ticket to fuss-free comfort. They’re vegetarian and can be made gluten-free if you choose a suitable cream and cheese. If you want a flavor twist, try smoked Gouda instead of cheddar or add a pinch of nutmeg for extra warmth. However you serve it, this dish is sure to make everyone feel at home.
