I’ve gotten many requests to veganize myclassic scalloped potatoes au gratin recipe and i challenged myself to make it WFPB compliant without using any oil. Mission accomplished friends!

But if you want to indulge a bit during the holidays you can top them with your favorite plant based cheese, i won’t judge! I’m a fan of provolone, pepper jack and smoked gouda from Follow Your Heart butwhatever rocks your tastebuds is fine! This walnut parmesan is a great choice too!

You are going to need a mandoline slicer to slice up the potatoes as thinly as possible.Preferably you’d be able to read the morning paperthrough those slices but don’t stress over it. Do your best to get them as thin as you can and if need be just increase the cooking time by 15 to 20 minutes or so.

I did a quick soak of the cashews that I then blended into a cheesy cream sauce with nutritional yeast, lemon juice, garlic and water. This is all you need toachieve that cheesy classic flavor and texture au gratinpotatoes have.

Let’s talk about the leeks!

Most definitely a favorite staple in myrefrigerator, leeks pack so much wonderful flavor I just can’t do without them.Basically a sweeter version of onions but with way more depth.

They are a great source of lutein and zeaxanthin twoimportant carotenoids for eye heath, on top ofbeing rich in fiber, calcium, iron, magnesium, phosphorus, potassium, vitamins A and K. You can use the entire leek including the mineral-dense little roots / filaments, just make sure to rinseeverything well as they are known to be full of grit and dirt.

Make the Scalloped Potatoes:

  • Slice the leeks lengthwise then chop them up. Add them to a bowl with cold water. Stir to rinse well and allow them to stay in the water for a few minutes.

  • Preheat a large skillet on medium low flame. Add a splash of water and the leeks with a pinch of sea salt. Saute until wilted and they start to get some color adding more water if needed as not to burn them, about 10 to 15 minutes Adjust seasonings to taste with more sea salt and black pepper. Set aside.

  • Meanwhile use a mandoline to thinly slice the potatoes. Rinse well in some cold water and dry on a tea towel. Sprinkle all over the top with a good pinch of sea salt and black pepper.

  • Lightly oil a large gratin dish including the sides. (You can use 2 small gratin dishes if you wish)

  • Layer the thinly slice potatoes on the bottom of the gratin dish overlapping each other. Spoon the sauteed leeks and spread them on top of the potato slices. Sprinkle with the fresh thyme.

  • At this point you can top with your favorite vegan cheese, loosely cover with aluminum foil and bake in the preheated oven for 45 minutes. Remove the foil and cook another 10 minutes or so until the cheese has melted. To brown the top you can transfer the gratin under the broiler flames for a few minutes until golden to your liking, just make sure that you are using a broiler proof dish.
