Preheat oven to 325°F. Liberally season the pork roast with salt and pepper on both sides. Add olive oil and butter to large Dutch oven and heat over medium-high until the butter melts, but does not burn. Add the pork roast to pan and brown on both sides, for about 8 to 10 minutes total.

Add the onions and garlic and sauté for 1 minute. Add the tomatoes, wine, thyme, oregano, fennel and hot sauce (if using) and bring to a boil. Cover, and put in oven. Braise for 3 to 4 hours, flipping once halfway through cooking time. If you are cooking less pork (only 1 pound or 1.5), you only need to braise for about 2 to 2.5 hours. Add more liquid (water, wine, or tomato sauce) if needed. I recommend adding more tomato sauce. (The liquid should come to about ⅓ of the way up the pork.) Meat is done when it’s practically falling apart. Place onto a cutting board and pull it apart with two forks, then add back to the pot and stir to combine.

Cook pasta according to package directions. Stir pasta into the pork shoulder ragu and serve with freshly grated parmesan cheese! Enjoy!
