Be sure to allow yourself plenty of time (about 3-4 hours minimum) to prepare everything and get it right. It will pay off. I actually sometimes make the sauce one day and the finished dish the next day.
SAUCE: Heat oil in a large Dutch oven or large kettle. Crumble beef and sausage into the pan and cooked until nolonger pink, breaking up clumps with a large fork. Meanwhile, process the onion, carrot and garlic in a food processor until very finely chopped. Add vegetables to the meat, mix well and cook over medium heat, stirring occasionally, until meat is no longer pink. Season with salt and pepper to taste then stir in crushed red pepper and oregano. Add tomaoto paste and mix well. Add the wine and mix well. Stir in the crushed tomatoes, tomato sauce and bay leaves and mix well.
Bring slowly to a simmer; cover and simmer 1-2 hours stirring occasionally. Add the brown sugar and the 3 tablespoons of grated Parmesan cheese amd mix well, simmering for anothger 15-30 minutes. Taste and adjust seasonings and remove the bay leaves. (This can be prepared early and set aside up to 2 hours, even a day ahead.)
FILLING: In a medium bowl, all filling ingredients and mix until thoroughly combined.
TO ASSEMBLE: Preheat oven to 350 degrees. Cook noodles (you'll need about 24) in a very large kettle in boiling salted water until just al dente, about 7-8 minutes and drain into a colander. Lightly spray a 13x9x4 baking pan** with non-stick cooking spray. Be sure to have all the all the assembly items ready before beginning. (NOTE: **If using a smaller 9" square pan, use 16 noodles and refrigerate any leftover filling.)
Spoon 1 cup of the sauce over the bottom to barely cover. Carefully layer ingredients over the sauce in the order given below:
Repeat the process 2-3 more times. Top all with remaining Noodles. Spoon remaining sauce over all to cover. Sprinkle with the 1 cup shredded Parmesan cheese.
Cut a large piece of foil big enough to "tent" it over the pan, and seal around the edges tightly as possible. Bake 45 minutes. Remove foil cover and bake an additional 15 minutes or until bubbly and lightly browned on top. Let stand at least 20 minutes before serving.
