So, let’s have a look at the FODMAP notes of the ingredients for this low FODMAP scalloped potato dish.

Potatoes: What Are The Best Potatoes For This Dish?

All potatoes are good potatoes but if we’re going to get into details, then go for starchy potatoes like russet potatoes or Yukon Gold. I don’t recommend waxy potatoes like red skinned potatoes because it won’t give this dish the richness in texture it needs.

Lactose-Free Cream & Whole Milk

I used a mixture of lactose-free cream and lactose-free whole milk for these low FODMAP scalloped potatoes. You can replace this with lactose-free half and half if you have it.

Seasonings

My partner is French so that meant no deviating from the original dish. I used nutmeg, salt and some pepper for this dish. Modern variations have other herbs like thyme, rosemary or oregano. 

But enough talk about ingredients and FODMAPs. It’s time to get cooking!

How To Make Scalloped Potatoes

All you need is 3 ingredients and some TLC to make a beautiful dish of low FODMAP scalloped potatoes. I mean come on, look at those layers.

Start by preheating the oven to 150 F or 302 C and washing the potatoes. Pat the potatoes dry and use a vegetable peeler to remove the skin. Rinse the potatoes and dry them again.

Use a mandoline slicer (if you have one) to slice the potatoes as thinly as possible. You can do this with a knife or use pre-sliced potatoes. Just make sure that the potatoes are about the same size so everything cooks evenly.

Mix the cream and milk in a bowl. Next, butter the sides of an oven safe baking dish. Add ¼ cup of the cream and milk mixture into the baking dish and arrange a single layer of potatoes. 

Season the potatoes with a generous pinch of salt and lightly season with black pepper and nutmeg. Pour another ¼ cup of milk and cream mixture and repeat with another layer of potatoes, seasoning and liquid. 

Do this until the baking dish is filled. Place the low FODMAP scalloped potatoes into the oven and bake on low for 1 hour and 25 minutes. These potatoes cook low and slow so that they melt in your mouth. Doesn’t that look like a thing of beauty?

TIP: Cover the potato dish with a layer of aluminum foil if your oven runs a little hotter and the potatoes start to brown. This will let the potatoes cook without burning the top.

Take the potatoes out of the oven and let them cool before serving. This dish is not only a favorite because of the flavor but mostly because it’s so easy to make and store!

Can I Prepare Scalloped Potatoes Beforehand?

I love this dish because I can prepare everything a day ahead and bake it when I need it. I make sure to cover the dish with a layer of saran wrap or aluminum while it’s in the fridge so it doesn’t dry out. 

Or you can bake the dish halfway through and place it covered in the fridge. Take it out of the fridge an hour or so before you’re going to serve and finish cooking it in the oven.

Can You Freeze Cooked Scalloped Potatoes?

Scalloped potatoes keep for up to 2 days in the fridge. After that, any leftovers should be frozen.

Portion scalloped potatoes into portions, wrap in aluminum foil and seal in a zip lock bag. Storing them in an airtight ziplock will keep them good for about 3 months.

How To Reheat Frozen Scalloped Potatoes

The best way to reheat frozen scalloped potatoes is to defrost them overnight in the fridge and heat them up in a 180C or 356C oven for about 15-20 minutes. You could microwave it too.
