Cheesy Polenta Lasagne with Mushrooms and Seitan

I made this last night and it was absolutely delicious. I used chicken breast instead of the seitan, but did everything else by the recipe. It's like a delicious macaroni and cheese, but with polenta. The polenta became super creamy and it was just a fabulous combination of tastes and textures!

preparation

Preheat oven to 425°F with rack in upper third. Lightly butter a 2-to 2 1/2-quart shallow baking dish.
Make cheese sauce:
Melt butter in a 2-to 3-quart heavy saucepan over medium heat. Whisk in flour until smooth, then cook roux, whisking frequently, until pale golden, 2 to 3 minutes.
Meanwhile, heat milk in a separate small saucepan until just about to boil. Add milk to roux in 2 batches, whisking constantly until very smooth. Bring to a boil, whisking, then cook, whisking, 30 seconds. Remove from heat and whisk in Fontina, half of Gruyère, nutmeg, and 3/4 teaspoon salt. Cover and set aside, whisking occasionally.
Make mushroom-seitan filling:
Cook garlic in oil in a 12-inch heavy skillet over medium-high heat, stirring, until beginning to turn pale golden. Stir in mushrooms, 1/2 teaspoon salt, and 1/4 teaspoon pepper and cook, stirring occasionally, until mushrooms are softened, about 3 minutes. Add seitan and thyme and cook, stirring occasionally, until mushrooms and seitan are slightly golden, about 4 minutes. Add water and cook briefly, scraping up any brown bits.
Assemble and bake lasagne:
Spread 1/2 cup cheese sauce in bottom of baking dish.
Slice 1 log of polenta into 1/4-inch-thick rounds and arrange enough rounds to cover bottom of dish, overlapping slightly. Spoon half of filling evenly over polenta, then spread with half of remaining cheese sauce (about 1 cup). Slice enough rounds from second log to form a second layer. Cover with remaining filling, then cheese sauce. Sprinkle with remaining Gruyère and bake until top is just bubbling and slightly browned, 15 to 20 minutes. Let stand 5 minutes before serving.
