Ingredients

3 lb Yukon Gold potatoes, thinly sliced (about 6–7 medium potatoes)
2 large yellow onions, thinly sliced
4 cups mushroom broth
⅓ cup whole wheat flour
1 tsp dried sage
1 pinch dried thyme
1 tbsp fresh rosemary, finely chopped
½ tsp garlic powder, optional
Freshly ground black pepper, to taste

Directions

Preheat oven to 375°F (190°C).
Thinly slice the potatoes (about ¼-inch thick) and onions.
Toss the potatoes and onions together and spread evenly into a 9x13-inch baking dish.
In a saucepan, whisk together the mushroom broth and whole wheat flour until completely smooth.
Stir in the thyme, rosemary, and black pepper.
Heat over medium, whisking constantly, until the mixture just begins to thicken slightly, about 3–5 minutes. It should still be pourable, not as thick as traditional gravy.
Pour the gravy evenly over the potatoes and onions.
Cover tightly with foil.
Bake for 2 hours, or until the potatoes are completely tender when pierced with a knife.
Remove the foil for the last 15–20 minutes if you’d like more browning on top.
Let rest for 10 minutes before serving.
