Spezzatino di Manzo is a delicious Italian beef stew that's packed with vegetables and tender beef in a rich red wine gravy. Serve over polenta for a warming comforting meal the whole family will love.
Preheat the oven to 320°F (160°C). Heat the olive oil in a large casserole and sear the beef over high heat, in batches, until browned. Transfer to a bowl and set aside.
Add the diced pancetta and cook, stirring, until it starts to crisp up. Transfer to the bowl with beef.
Add a splash of red wine to the pan and let it cook down. Reduce the heat, add a little olive oil and the onion, celery and carrots. Season with the salt and pepper and sprinkle with the sugar.
Sauté over low heat for 10 minutes, stirring frequently, until the vegetables are very soft. You can add a splash of broth or wine to the pan, as needed, while the soffrito is cooking.
Stir in the mushrooms and garlic and cook for a minute or so. Add the wine and balsamic vinegar and stir in the tomato paste.
Pour in the beef broth and bring to a simmer. Return the beef and pancetta plus any juices to the pan and stir everything together. Add the rosemary and bay leaf, cover the pot with a tight fitting lid and transfer to the oven for 90 minutes.
Check the stew at this point – is the beef very tender? If yes then take out of the oven. If not, continue to cook for a further 30 minutes.
Dissolve the cornstarch in a little cold water and add to the stew. Bring to a simmer and stir until the stew thickens.
Discard the bay leaf and check the seasoning, adding salt and pepper if needed. Serve over buttery soft polenta , mashed potatoes or pasta.
