Scalloped potatoes VS Potatoes au gratin
There are a few key differences between scalloped potatoes and potatoes au gratin. While both contain milk and butter, potatoes au gratin contains cheese and usually omit the flour. The latter is also sometimes referred to as Dauphinoise potatoes. Regardless of whatever you call it, it WILL take center stage at your thanksgiving or holiday table.
Now, traditional scalloped potatoes tend to use butter, cream, and other forms of dairy, but not this one! No dairy and no eggs are needed, but you’d never tell. It’s just as rich and creamy and perfect to make ahead of time too.

How do you make vegan scalloped potatoes?
- Potatoes- Starchy, white potatoes are best. Russet, Yukon gold, and Idaho potatoes are all fantastic options.
- Vegan butter– Avoid using vegan butter from a tub or spread. Instead, use blocks or sticks, which generally don’t have added fillers or water in them.
- Onion and garlic– To flavor the roux.
- Flour– White all purpose flour or plain flour.
- Milk of choice– I used unsweetened almond milk, but soy, coconut, and other plant based milks can be used. Just be sure it has no added sugar or flavorings in it.
- Vegetable broth– Also known as vegetable stock .Use a good quality and full flavored vegetable broth.
- Salt and pepper– To taste.
Start by thinly slicing your potatoes, around 1/8 inch in thickness, and set them aside. Next, prepare the sauce. In a non-stick pan or small saucepan, add the butter and place it over medium heat. Once melted, add the onion and garlic and cook until they have softened. Add the flour and whisk until a thick paste appears, then reduce the heat to low. Combine the milk and vegetable broth then slowly add it to the pan, while continuing to whisk, until smooth. Once everything is added in and smooth, turn the heat back up to medium and let it simmer for another minute. Add the salt and pepper and remove from the stove.
Now, grease a 9 x 13-inch baking dish. Place 1/3 of the sliced potatoes to the bottom of the dish, then season with salt and pepper. Carefully pour 1/3 of the sauce/roux over the top of them. Repeat the layers, ensuring the final layer is the sauce. Cover and bake for 45 minutes. Uncover and bake for a further 30-35 minutes, or until golden on top.
Remove the scalloped potatoes from the oven and let it sit for 15 minutes before serving.
Can I make this ahead of time?
Easily make dairy free scalloped potatoes ahead of time.
Prepare everything as instructed except keeping the 1/3 cup of sauce/roux separate. When ready to bake, pour it over the top of the potatoes then cover and bake it. You can make this dish up to 3 days ahead of time.
Storing, freezing, and reheating tips
- To store: Leftovers can be stored in the refrigerator, covered, for up to 5 days.
- To freeze: Transfer the potatoes from the baking dish and place them in an airtight container, then store that in the freezer for up to 2 months.
- Reheating: Either microwave the potatoes in 30-second spurts until warm or in a preheated oven.
