Place pancetta and garlic into the food processor and pulse until finely minced. Set aside.

Warm olive oil in a heavy-bottomed pot over medium heat. Add the pancetta and garlic mixture. Sauté, stirring, until the pancetta renders and the garlic is fragrant, about 4 to 5 minutes.
04 -
Add the processed carrot, celery, and onion mixture to the pancetta-garlic base. Season with 1 teaspoon kosher salt. Cook, stirring occasionally, until deeply browned and aromatic, about 15 to 20 minutes; lower the heat if browning too rapidly. Move the mixture to the pot's edges.

Generously season ground beef and pork with 1 teaspoon kosher salt each. Add the meats to the center of the pot. Let brown undisturbed for 2 to 3 minutes per side, then break up into crumbles and combine with the vegetables. Sauté until thoroughly browned, 8 to 10 minutes.
06 -
Stir in tomato paste and cook for 2 to 3 minutes, allowing it to coat the meat and vegetables and darken slightly.
07 -
Raise the heat to medium-high and add the red wine. Stir vigorously, scraping any browned bits from the bottom. Cook until the wine is nearly absorbed, about 4 to 5 minutes.
08 -
Bundle together rosemary and thyme and secure with kitchen twine, or chop finely if needed. Add herbs, bay leaves, parmesan rind if using, crushed tomatoes, and broth or water. Stir thoroughly.
09 -
Reduce heat to medium-low and simmer uncovered, stirring occasionally, for 90 minutes. If the sauce thickens excessively, add a splash more broth or water, adjust heat lower, or partially cover the pot.

In a large baking dish, spread a thin layer of bolognese sauce. Arrange lasagna noodles over sauce. Layer half of the ricotta mixture, then top with mozzarella and Italian cheese blend, using about one quarter of combined cheeses. Repeat bolognese, noodles, ricotta, and cheese layers to create four alternating layers. Finish with remaining cheeses.

Preheat the oven to 375°F (190°C) with the rack in the center position. Transfer cold baking dish to a rimmed baking sheet. Bake covered for 60 minutes, removing foil for the final 10 minutes to brown the top. For an extra golden finish, broil during the last 5 minutes if desired.
