Cheesy Scalloped Potatoes
In this recipe, thick-cut potato rounds are smothered in a luscious cream sauce. I prefer using a mandoline slicer to ensure the potato slices are uniform every time. This is hands down the most amazing cheesy scalloped potato recipe I’ve ever tasted.
Scalloped Potatoes vs. Au Gratin Potatoes
There’s often confusion between scalloped potatoes and au gratin potatoes because they are quite similar. We’re calling this dish cheesy scalloped potatoes, and here’s why: we’re combining the best elements of both dishes.
- Scalloped Potatoes: Traditionally consist of sliced potatoes layered in a casserole dish, baked with heavy cream and herbs.
- Au Gratin Potatoes: Include grated cheese sprinkled between the layers, resulting in a cheesier, more decadent dish.
In both recipes, potatoes are sliced into rounds, but scalloped potatoes are typically cut thicker than those in au gratin dishes.
Best Potatoes for Scalloped Potatoes
When selecting potatoes for scalloped potatoes, I recommend using Russet potatoes (as used in this recipe) or Yukon Gold potatoes. These varieties are starchy enough to help thicken the sauce and result in soft, tender potatoes. Avoid waxy potatoes, as they may not soften properly. Slice the potatoes uniformly—using a mandoline helps—to a thickness of 1/8 inch to 1/4 inch (0.3 cm to 0.6 cm) to ensure even cooking.
Adding Ham to Cheesy Scalloped Potatoes
Many people ask if ham can be added to this dish. Absolutely! Adding cubed ham between the potato layers transforms this side dish into a hearty main course. Simply include ham in the ingredients list and incorporate it as you assemble the dish. It’s an easy way to elevate this already delicious recipe.
