Instructions

Preheat your oven to 400F (200C). Grease a 9" x 13" baking dish with vegan butter, oil, or omit for an oil-free version.
Make the creamy vegan sauce by adding the non-dairy milk, all-purpose flour, garlic, and salt to a blender, and blending until completely smooth. *If you do not have a blender, simply mince or press the garlic and whisk everything together in a bowl instead. Set aside.
Layer the potato and onions slices by spreading about 1/3 of the potatoes across the bottom of the baking dish. Spread 1/2 of the onion slices over the potatoes. Cover the onions with another third of the potato slices, followed with the remaining half of the onions. Top with the rest of the potatoes slices.
Pour the creamy vegan sauce over the potato and onion mixture, cover with foil and bake for 30 minutes. The liquid should be lightly bubbling around the edges. Remove the foil and bake for another 25 to 35 minutes until the potatoes are cooked through.
Spread the Melty Stretchy Gooey Vegan Nacho Cheese across the surface of the potatoes then return to the oven for another 5 - 10 minutes to melt the cheese. You can optionally put the baking dish under the broiler to brown the cheese for just 1 - 2 minutes, keeping a close eye so it doesn't burn.
Serve hot, garnishing with fresh thyme leaves, chopped chives, or nothing at all.

Notes

Notes on the vegan cheese:

The vegan cheese topping is optional and you can skip it if you prefer.
I use my Melty Stretchy Gooey Nacho Cheese recipe or my Nacho Cheese Love recipe found in my cookbook to top the scalloped potatoes. When making these cheeses add 1/2 cup more water to the recipe so that the cheese will be easier to spread over the scalloped potatoes. If you make the cheese ahead of time, it may tighted up as it cools, feel free to add more water if needed.
If you prefer to use a store-bought vegan cheddar, use 2 cups grated cheese. Note that store-bought vegan cheese usualy doesn't melt as well.

To make ahead of time: bake the potatoes and make the cheese sauce and store them separately in the fridge for 1 - 2 days. I recommend underbaking the potatoes slightly so that they don't get too mushy when reheated. When ready to enjoy, cover the potatoes with foil and reheat at 350F (180C) for 20 - 30 minutes, or until warmed through. Then spread the cheese over top and bake another 5 - 10 minutes to melt the cheese.

Soy-Free: To keep this recipe soy-free, choose almond or oat milk rather than soy milk.
