- Place a large pot of water over high heat; bring to a boil. Add noodles; boil for 10 minutes, stirring to prevent sticking. Drain noodles and briefly rinse under cool water to prevent sticking; set aside.
- Place a very large nonstick skillet over medium-high heat. Add 1 tablespoon of oil and onions; cook, without stirring for 3 minutes, and then continue to cook, stirring occasionally, for another 7 minutes. Add rosemary and water; scrape up any food from bottom of pan using a wooden spoon. Cook until water evaporates, about 2 to 3 minutes. Add soda and cook until onions are nicely browned and soft, about 3 to 4 minutes; remove to a large bowl and set aside.
- Coat same skillet with cooking spray; place over medium-high heat. Add mushrooms and cook, without stirring, until they start to brown, about 2 to 3 minutes; sprinkle with salt and stir. Continue to cook mushrooms, stirring occasionally, until liquid evaporates and mushrooms are browned, about 3 to 4 minutes; add to onion bowl. (If mushrooms are too cramped in skillet, either use 2 skillets or cook them in 2 batches.)
- Preheat oven to 350ºF.
- To make sauce, place same skillet over medium heat. Add remaining 2 tablespoons of oil and butter; allow butter to melt. Add flour, stirring constantly with a wooden spoon, until combined, about 1 minute. Add milk, a little at a time, stirring to prevent lumps; bring to a boil. Stir in garlic and cook, stirring continuously, until thick, about 3 to 4 minutes. Add nutmeg and 2 tablespoons of cheese; stir to combine and set aside.
- To assemble lasagna, spread 1/3 cup of sauce over bottom of a 9- X 11-inch lasagna pan or baking dish. Place 3 noodles over sauce in a single layer; spread with 1/3 cup of sauce and about 1 1/2 cups of onion-mushroom mixture. Top with 1/4 cup of sauce and then 3 more noodles; spread with 1/3 cup of sauce and about 1 1/2 cups of onion-mushroom mixture. Top with 1/4 cup of sauce and then 3 more noodles; spread with 1/3 cup of sauce and about 1 1/2 cups of onion-mushroom mixture. Top with 1/4 cup of sauce and then top with the remaining 2 tablespoons of cheese.
- Bake for 20 minutes; change oven temperature to broil. Broil until top of lasagna is crispy, about 2 to 3 minutes. Remove from oven and let rest for 10 to15 minutes before slicing into eight pieces. Yields 1 piece per serving.
