There is a little prep work that needs to be done before cooking this recipe. Dice the chuck steak into 2 cm chunks, and remove the big chunky pieces of fat. You don't want a mouthful of that.
Dice the onion, and chop up the carrots and celery into small pieces. Mince 3 garlic cloves in a garlic crusher, or use pre-minced garlic (1 teaspoon equals one clove).
Thinly slice the mushrooms, or use pre-sliced.Now for the rosemary and thyme, remove the leaves from the stems and finely chop these up. Now, heat up some olive oil in a pot or Dutch oven. Add the beef chunks, brown them up for a few minutes, and then remove them from the pot and set them aside in a bowl. No need to fuss over it for too long. It is also best to do this in batches to make the browning easier.(Refer to the notes below for how to do this in your slow cooker) Next, add the onions, garlic, carrots, celery, and white mushrooms to the same pot. Easy peasy! Please give them a quick sauté until they're softened and fragrant.
Time to amp up the flavours. Add tomato paste, beef stock, red wine, thyme, rosemary, and those beautiful mushrooms to the pot. Bring it all to a boil, and let the magic happen.
Now, reintroduce the beef to the pot and stir it well. Lower the heat, cover it, and let it simmer for a few hours. No need to babysit it—just let the Dutch oven do its thing constantly.
When the beef is tender and the flavours have melded into a tantalizing symphony, it's time for the final touches. Mix cornflour and water in a bowl until dissolved, then add it to the pot along with the gnocchi. Stir, let it cook for a bit longer to thicken the sauce, and cook the gnocchi to perfection. Finally, dish up your mouthwatering creation. Serving it with steamed green vegetables or crusty bread, prepare to savour the flavours. Sprinkle some fresh parsley on top for a pop of colour and freshness.
