½ cup grated Parmigiano-Reggiano, plus more for serving
Freshly ground black pepper
Chopped parsley
Instructions
Season pork with salt and pepper. Heat oil in a large heavy pot over medium. Cook pork, turning often, until evenly browned, 10–12 minutes. Transfer to a platter and pour off pan drippings.
Wipe out any burned bits from pot, but leave the golden-brown pieces (doing this will keep the finished sauce from tasting bitter). Add onion and garlic to pot and cook, stirring occasionally, until onion is starting to brown and caramelize, 12–15 minutes. Stir in tomato paste and cook, stirring occasionally, until slightly darkened in color, 5–8 minutes.
Add wine and cook, scraping up any browned bits, until reduced by about half, 5–8 minutes.
Add tomatoes, crushing with your hands as you go, then add thyme, rosemary, and bay leaves; stir in 2 cups water. Add pork with any juices accumulated on the platter; season with salt and pepper.
Bring liquid to a boil, then reduce heat and simmer, partially covered, until pork is falling-apart tender, sauce is thickened (it will be thicker than a typical pasta sauce), and flavors have melded, 2½–3 hours.
Using 2 forks, shred the pork; taste and season with salt and pepper.
Pork can be prepared a few days ahead. Let it cool, cover and chill. Reheat gently before serving.
To make the polenta, bring chicken stock and milk to a simmer in a large pot. Whisking constantly, gradually add polenta; reduce heat to medium-low. Cook, whisking often, until polenta is tender and creamy, 20–25 minutes (if polenta becomes too thick too soon, loosen mixture by adding a little water and continue cooking). Add butter and ½ cup Parmesan to polenta and whisk until melted; season to taste with salt and pepper.
Spoon polenta into bowls or onto a platter and top with pork. Scatter parsley and more Parmesan over top.
