There are times you drink green smoothies, eat kale salads, and have vegan soup–and then there are times you eat baked scalloped potatoes made with cream and leeks, topped with Italian taleggio cheese.

As a dietitian I will always tout the benefits of leafy green vegetables over greasy fried food, however I will also defend that a hearty, home-cooked potato dish deserves a spot at your table.

We are big fans of spuds and baked, roasted, mashed, and smashed potatoes make regular appearances on our plates. Potatoes received a bad wrap in the carbohydrate-phobic, Atkins crazed 1990’s and 2000’s but–in case you haven’t heard–carbs are back in, big time. And that’s great news because potatoes are an excellent source of vitamin C, a good source of potassium and provide fiber to keep your digestion moving. Which you’ll need if you want to fit in a little pie after that holiday meal.

How to make Simple Creamy Scalloped Potatoes with Leeks

Scalloped potatoes can be an intimidating recipe, but it’s truly as simple as layering boiled potatoes with creamy vegetables and then baking until golden brown.

This easy scalloped potatoes recipes starts by thinly slicing the potatoes and boiling them until slightly soft, then removing from water and setting aside. In the mean time, the leeks and mushrooms are softened in a pot and then the half and half and milk are cooked down until you have a creamy vegetable and dairy mixture.

The last part is the fun part: layering your scalloped potatoes! In a square or round glass baking dish, layer potatoes with the creamy vegetables and then top with cheese and rosemary. Continue this until you’ve used up all of the ingredients and then bake until soft and golden brown, about 60 minutes.

That’s it! This is a perfect recipe for Thanksgiving or the holidays because it can be prepped up to three days ahead of time and then popped in the oven an hour before serving. In fact, I find that this 1-3 day prep period actually makes for a much more flavorful scalloped potato recipe because the rosemary and other flavors have time to marinate.
