Method

  • Bring the sauce to room temperature.
  • In a large bowl, whisk the ricotta, egg yolks, Parmesan, 1 1/2 teaspoons salt, black pepper, nutmeg, and cayenne pepper.
  • Chill the filling until ready to assemble the lasagne.
  • Preheat the oven to 400F.
  • Butter an 11 x 14 x 3-inch lasagne baking pan.
  • Bring a large pot of water to a boil.
  • Add the olive oil and the remaining tablespoon salt.
  • One at a time, add the lasagne noodles; cook until al dente, 2 to 3 minutes less than the manufacturers instructions.
  • Remove the noodles with tongs; drain in a colander.
  • Spread about 3 cups sauce on the bottom of the baking dish.
  • Place a single layer of lasagne noodles over the sauce, overlapping them slightly.
  • Spread about 2 cups sauce over the noodles and about half of the ricotta filling mixture over the sauce.
  • Top with a layer of lasagne noodles, again slightly overlapping them.
  • Repeat with more sauce and the remaining ricotta filling mixture.
  • Top with a final layer of lasagne noodles.
  • Spread a layer of sauce over the noodles, and finish with a layer of sliced mozzarella rounds.
  • Bake until the sauce is bubbling and the cheese is melted, at least 1 hour.
  • Cover with aluminum foil if the cheese starts to brown too early.
  • Let the lasagne stand 10 to 15 minutes before serving.
  • Heat the butter and olive oil in a large cast-iron or enamel pot over medium heat.
  • Add the onions, and cook until they begin to soften, about 5 minutes.
  • Add the celery and carrots, and cook until the vegetables are tender, 8 to 10 minutes.
  • Add the ground sirloin and veal, and cook, stirring occasionally, until the meat is no longer pink.
  • Add the milk, and cook at a gentle simmer, skimming fat from surface, until the liquid has reduced by half, about 50 minutes.
  • Add the wine, and simmer until liquid is reduced by half again, about 40 minutes.
  • Add the beef stock, tomato paste, salt, and pepper; simmer gently until the sauce thickens, 40 to 45 minutes.
  • If using for lasagne, set aside to cool slightly before assembling.
