Preheat oven to 400°F. Lightly grease a 9x9 baking dish with butter. Thinly slice the potatoes using a mandoline.
4-6 large yukon gold potatoes
In a large stockpot or sautee pan, melt butter. Add onion and saute for 2-3 minutes, adding a pinch of salt to begin layering in the flavor. Add garlic and continue to saute for 1-2 minutes. Then stir in the flour and continue to stir for 1-2 minutes to ensure the flour does not burn.
Whisk in the vegetable broth until combined, then whisk in milk. Add any remaining salt as needed, white pepper, and 1 1/2 teaspoons thyme. Bring cream sauce to a simmer and continue to lightly simmer for 4-5 minutes, being careful it doesn't boil. Remove from heat.
1/2 cup vegetable stock, 1 cup whole milk, 1/2 teaspoon kosher salt, 1/4 teaspoon white pepper, 1/4 teaspoon black pepper, 2 teaspoons fresh thyme
Layer half of the potato slices at the bottom of the greased baking dish for the first layer.
Pour over half of the cream sauce on top. Sprinkle ¾ cup of the shredded gruyere and ½ cup of parmesan on top of the first layer of cream.
Layer the rest of the potato slices in the pan and pour the remaining cream sauce on top. Sprinkle the remaining 1/2 cup of gruyere on top of the finished dish.
Cover the baking dish with foil and bake for 25 minutes. Uncover and continue cooking for 15-20 minutes, until cheese begins to turn golden brown and potatoes are tender when pierced with a fork. The sauce should also be bubbly.
Let cool slightly for about 10 minutes. Garnish with the remaining thyme. Serve and enjoy!
Notes
9x13 baking dish will also work, just reduce the cooking time by 5-10 minutes as it will be thinner and need less cook time.
Dried Thyme: to substitute dried thyme, use 1 teaspoon in the cream sauce and omit the garnish.
*Look for cheese specifically labeled vegetarian, if needed.
