Mashed potatoes may be a traditional Thanksgiving side, but they aren't the most practical for serving a large crowd. They're best freshly made, and although you can keep them warm over a pot of simmering water, who has time or stovetop space for that?
If you're attending a potluck and in charge of bringing a potato side, make this wildly delicious layered potato gratin. The half-and-half is infused with roasted garlic, rosemary, and thyme before being poured over the thinly sliced potato rounds. Instead of regular old cheddar or parmesan, the ingredient list calls for manchego and smoked gouda.
The resulting dish is insane! The top is crispy and cheesy, and the potatoes melt in your mouth. It really is a spectacular side that would be excellent paired with any roast like turkey, ham, or whole beef tenderloin. To check out the recipe, read more.
Make Ahead: The gratin can be prepared through Step 3; refrigerate overnight. Return to room temperature before baking.
