Your slow cooker will do most of the work to make this aromatic pasta dish. The lamb stew meat becomes tender in the slow cooker as it absorbs the ragù sauce flavors, making a delicious topping for pasta along with freshly grated Parmesan cheese.
Slow-Cooker Lamb Ragù with Rigatoni
In a 5-to-6-quart slow cooker, combine the tomatoes and juices, wine, onion, tomato paste, oregano, garlic, and chili flakes. Season the stew meat with the salt and nestle it in the tomato mixture. Cover and cook until the meat is very tender and can easily be pulled apart, about 4 hours on high or 6 to 8 hours on low.
Shred the meat with 2 forks and stir it into the sauce. Taste and adjust the seasoning with more salt as needed. Add enough vinegar to brighten the flavor.
Cook the pasta according to the package directions. Return the pasta to the same pot and add enough of the sauce to coat the noodles, stirring over medium-low heat for about 2 minutes.
Serve the pasta in warm bowls, with another big spoonful of the sauce on top of each, and plenty of Parmesan cheese.
