01 - Heat olive oil in a large pot over medium heat. Add the chopped onion, carrots, and celery. Sauté for 5 to 7 minutes until the vegetables are soft and translucent.
02 - Incorporate minced garlic and continue to cook for 1 to 2 minutes until fragrant.
03 - Add ground beef and ground pork to the pot. Brown the meats, breaking them apart with a spoon, and cook for 8 to 10 minutes until fully cooked and no pink remains.
04 - Pour in the red wine to deglaze the pan, scraping up any browned bits. Let the wine simmer for 3 to 5 minutes until it reduces slightly.
05 - Stir in the tomato paste and cook for 1 to 2 minutes until the paste is blended and aromatic.
06 - Add crushed tomatoes, milk or cream, bay leaves, dried oregano, dried thyme, salt, and black pepper. Mix thoroughly to combine all ingredients.
07 - Bring the mixture to a gentle simmer, reduce the heat to low, cover, and cook for 90 to 120 minutes. Stir occasionally to prevent sticking.
08 - Taste and adjust seasoning as necessary. Remove the bay leaves before serving. Serve hot over cooked pasta, finished with grated Parmesan cheese.
