Directions:

1. Preheat the oven to 400 degrees F.

4. Add the flour and stir to combine. Slowly whisk in the vegetable stock, followed by the milk.
5. Add the salt, white pepper, black pepper, and thyme. Bring to a boil then reduce the heat and simmer for about 5 minutes.

7. Add the other 1/2 of the potatoes in an even layer, pour the remaining onion mixture over the top, and sprinkle the remaining cheese evenly over the top.
8. Cover with foil and bake for 25 minutes. Remove the foil and bake for another 15-20 minutes or until the cheese begins to turn golden brown on top.
