An Easy Classic

Of all the potato side dishes, from oven-roasted potatoes to creamy buttery mashed potatoes, nothing says comfort food like this scalloped potatoes recipe.

So exactly what are Scalloped Potatoes? Said to have originated in England, the word ‘scallop’ refers to how the potato is sliced. Thin and uniformly cut potatoes are layered in a casserole dish, covered with a seasoned onion cream sauce, and baked. The result is this savory scalloped potato recipe!

Ingredients

• Potatoes – Yukon gold potatoes (or red potatoes) have tender skin and don’t require peeling (they hold their shape well). Russet potatoes or Idaho potatoes will work; however, they tend to break apart (but still taste good).
• Onions – Diced onion is a classic ingredient and adds a lot of flavor to this recipe.
• Cream Sauce – The cream sauce for these potatoes is quick to make with flour, butter, milk, and broth.
• Seasonings – Simple seasonings in this recipe include salt, pepper, onion, and garlic.

Variations

• Cheese – If you’d like to add cheese, remove the sauce from the heat and stir in a handful or two of shredded cheese. It will melt from the heat of the sauce.
• Herbs – Add ½ teaspoon of dried thyme or crushed rosemary, or 1 tablespoon fresh parsley.

How to Make Scalloped Potatoes

Making scalloped potatoes from scratch takes time but is easy. While traditional scalloped potatoes do not have cheese, we sometimes add a little bit!

1. Thinly slice potatoes & onions.
2. Make homemade sauce (recipe below)
3. Layer potatoes, onions, and sauce. Cover and bake.
4. Remove the foil and bake a bit more; this step creates a delicious golden brown topping on the scalloped potatoes.

IMPORTANT Cool 20 minutes before serving to allow the sauce to thicken.

Tips for Perfect Scalloped Potatoes

• Slice the potatoes evenly to ensure the scalloped potatoes cook evenly
• Use a mandoline to make this job extra quick (a $25 mandoline like this one does a great job and will save you lots of time)
• A roux is the foundation for a creamy sauce. A roux means to cook fat (in this case butter) and flour and add liquid to make a sauce!
• If you decide to add cheese to the sauce (which will actually make these intoPotatoes Au Gratin) remove the sauce from the stove and stir in 1 1/2 to 2 cups of cheese (cheddar/gruyere are great choices).
• Season the potatoes with salt and pepper between layers.
• Cover with foil while it bakes; this allows it to steam, and the potatoes will cook a bit faster.

To Make Scalloped Potatoes Ahead of Time

To prepare this scalloped potato recipe ahead of time, partially bake them as directed below.

1. Prepare as directed in the recipe below.
2. Bake the dish covered for 50-60 minutes.
3. Remove from the oven and cool completely on the counter (leave them covered, the steam will help to finish cooking).
4. Cover well and refrigerate.
5. On the day of serving, remove from the fridge at least 30 minutes before baking. Bake uncovered for about 35 to 40 minutes or until heated through.

What is the Difference Between Scalloped and Au Gratin Potatoes?

Potatoes au Gratin are also called cheesy potatoes because the white sauce is actually a cheese sauce (and they often have cheese sprinkled between the layers and/or breadcrumb topping).

This scalloped potato recipe can (of course) be topped with cheese or have cheese added in but sometimes I love the simplicity in this recipe without cheese. The sweetness of the onions and milk is the perfect addition to these sliced potatoes!

Can You Freeze Scalloped Potatoes?

These potatoes will keep in the fridge for about 4 days and reheat well in the microwave, oven or in a frying pan! If you want to freeze them longer, yes, scalloped potatoes can be frozen!

Almost any casserole dish can be frozen perfectly with a little know-how. If making a freezer meal, the best way to freeze scalloped potatoes is to not fully cook them all way, but leave them a little undercooked. Then, once they are cooled in the fridge, portion them out the way you want to and wrap carefully before putting in the freezer. To reheat, simply thaw and finish the cooking until the potatoes are tender again!

While that’s a great option, most often we want to freeze leftovers. In this case, these scalloped potatoes freeze well, although I do find they sometimes break apart a bit when reheated but they still taste great!
