1. Preheat oven to 375°F. Cook onion in large nonstick skillet coated with cooking spray over medium-high heat 3 minutes, stirring often. Add all mushrooms and garlic; cook, stirring often, 3 to 4 minutes, or until onion is tender. Add 3/4 cup milk, and bring to a simmer, stirring occasionally.
2. Mix cornstarch with remaining 2 Tbs. milk, and stir into mushroom mixture. Add cream cheese and wine, and cook, stirring often, 1 to 2 minutes, or until smooth and blended. Remove from heat. Add salt, pepper and nutmeg.
3. Coat 10x10-inch baking dish with cooking spray. Spread 3 Tbs. mushroom sauce in bottom of dish. Layer 1/3 of polenta slices over sauce. Sprinkle 1/4 cup Parmesan cheese over polenta. Top with half of remaining mushroom sauce. Layer with 1/3 of polenta slices and remaining sauce, and top with remaining polenta.
4. Bake, uncovered, 35 to 40 minutes, or until bubbly. Sprinkle lasagna with remaining 1/4 cup Parmesan. Broil 3 to 5 minutes, or until cheese is lightly browned. Remove from heat. Cover loosely with foil, and let stand 10 minutes before serving.
Does anyone know if you can make your own polenta from corn meal for this recipe? I'm not sure if polenta is in any way different than just making it from scratch with course corn meal - any suggestions?!
I am sure you can make your own with cornmeal. I've tried the polenta in the tubes, and I personally prefer the homemade stuff. I guess you could cook it in a baking sheet and then cut it into squares rather than using the circles. it would just take a bit more preparation for cooking and setting but it would be worth it :)
Best of luck to you! :)
This recipe says you can cook it, then cool it overnight if you want to slice the polenta.
