Ingredients

• 9 tablespoons unsalted butter, divided
• 3 tablespoons plus 1 teaspoon all-purpose flour
• 2 2/3 cups whole or lowfat milk
• 1/4 teaspoon freshly ground nutmeg
• Salt and ground black pepper
• 1 medium onion, chopped
• 1 garlic clove, minced
• 1 pound assorted (shiitake, oyster, porcini, chanterelles, etc.) or just cremini mushrooms, thinly sliced
• 1 tablespoon finely chopped fresh sage (I used less)
• 2 pounds Napa cabbage, 12 large leaves removed from the head, and reserved, the remainder sliced thin
• 1/2 cup dry white wine
• 1 1/2 pounds (about 4) yukon gold potatoes, sliced 1/8-inch thick
• 1 cup grated Parmesan cheese, or Västerbotten (the chef’s preference).

Preparation

Heat oven to 350 degrees.

In a large sauté pan over medium heat, melt 6 tablespoons of the butter. Add flour, stir for 3 minutes (do not allow to brown), then gradually whisk in milk, stirring until thickened, 5 to 8 minutes. Stir in nutmeg and season with salt and pepper to taste. Scrape sauce into a bowl, and reserve.

Wipe out sauté pan (rinse if needed) and melt 2 tablespoons of the remaining butter over medium heat. Add onion and garlic, and sauté until onions are translucent. Add mushrooms, sage and sliced cabbage, and sauté until fragrant and the cabbage is tender, 10 to 12 minutes. Add wine and sauté until it has evaporated. Add reserved sauce and simmer for 10 minutes. The mixture should be very thick. Season with salt and pepper to taste.

While the mushroom and cabbage mixture is simmering, pour 6 cups of water into a stock pot, and bring to a boil. Add whole cabbage leaves, and blanch for 2 minutes. Drain under cold water, and pat dry on towels.

Grease a 9-by-9-inch baking dish or a lasagna pan of your choice (I used this, which is 8-by-12-inch) with remaining 1 tablespoon of butter.

To assemble the lasagna, line the bottom of the dish with half the cabbage leaves, and top with half the potatoes, half the creamed mushrooms. Repeat the layering of cabbage, potatoes and mushrooms, and top with grated cheese. Cover snugly with foil, and bake for 30 minutes. Uncover, and bake until the top is golden brown and potatoes are tender, about 20 minutes but up to 10 minutes longer if needed. Allow to cool for 10 minutes, and serve.

Notes

Do ahead: I prepared the sauce and all of the vegetables and then ran out of time when I made this, stashing them in the fridge separately and baking it the next day, which works totally fine. You can also make the dish, chill it, and bake it when needed, and leftovers reheat well too. Finally, you could freeze the whole dish for a later date.
